Promotional emails are one of the most economical ways for any business to connect with customers. Research shows a message is five times more likely to be seen through email than on social media like Facebook or Twitter. That’s why musicians use email marketing software to share their performance schedule with their fans, non-profits use it to get donations and photographers use it to promote their portrait services. It just works.
If you’re serious about growing your business, building a healthy email list should be one of your top priorities. When it comes down to it, your list is one of the only online assets that you have 100% control over. Having a solid social media presence is absolutely essential (here’s why), but you’ll always be at the mercy of new and changing algorithms (think Facebook’s Edgerank). And achieving high search engine rankings is great too, but again, you’re at the mercy of changing algorithms and updates.
Save any new documentation as a PDF for download, and require that individuals enter their names and email addresses in order to access it. The value of the information you are offering is directly proportional to the amount of personal data your customers are willing to provide, so make sure the tradeoff is fair. A highly anticipated white paper or report can garner a high number of new email subscribers who are openly expressing interest in your brand, so don’t leave this opportunity unaddressed. https://www.sageworld.com/img/dist-emailcampaigns-top.png
In dividing your list in this manner, you give yourself the ability to send more targeted communication. Some customers want both product and sales updates, while others might only want to hear about new versions. If you don’t give them the chance to choose, you risk losing them all-together. Since customers make the best buyers, it’s fairly obvious why you want to keep them subscribed to your customer email list.
Word of mouth communications and peer-to-peer dialogue often have a greater effect on customers, since they are not sent directly from the company and are therefore not planned. Customers are more likely to trust other customers’ experiences.[22] Examples can be that social media users share food products and meal experiences highlighting certain brands and franchises. This was noted in a study on Instagram, where researchers observed that adolescent Instagram users' posted images of food-related experiences within their social networks, providing free advertising for the products.[26]
A call to action (CTA) is a word or phrase that encourages readers and subscribers to do something specific. Examples of calls to action include “subscribe”, “shop now”, “get the free ebook”. You use CTAs on landing pages, blog posts, in email newsletters, and more. When someone does what you want as a result of your call to action, that’s called a conversion. In email marketing, a conversion often means following a link in a newsletter to visit another resource.
Even better was the fact that we had built the Foundr brand up to the point where we had people actually ask to become an affiliate of ours. Our very brand became an important leveraging point for us because we had developed it to the point where people would want to become associated with our brand. Obviously this didn’t happen overnight and it took many years of work to get us to that point, but it was a great side-benefit to all the success we had achieved so far.
Within the past decade there has been a podcasting revolution going on, with the number of Americans who listen to podcasts doubling in seven years. Maybe it’s because they’re just so convenient and so much easier to consume, or maybe it’s because the format is just somehow perfect for storytelling. Whatever it is, podcasting is here to stay and is one of the most engaging forms of media out there.
BuzzFeed – The popular news and entertainment website earns revenue by selling advertisements on their site, so the key objective of their marketing team is to drive more traffic. With that in mind, BuzzFeed sends regular email newsletters containing links to stories on their website with the goal of increasing the number of visits they get each month and increasing the amount of revenue they generate.
Shifting the focus to the time span, we may need to measure some "Interim Metrics", which give us some insight during the journey itself, as well as we need to measure some "Final Metrics" at the end of the journey to inform use if the overall initiative was successful or not. As an example, most of social media metrics and indicators such as likes, shares and engagement comments may be classified as interim metrics while the final increase/decrease in sales volume is clearly from the final category.
With so many of the us depending on the internet to stay tuned into what's going on in our lives and in the world, it's no wonder that direct mail, or "direct classic" as the industry sometimes refers to it, has become an afterthought for small business marketing strategies. Postage is getting more and more expensive. Plus, email delivery and online communications are near immediate compared to the time it takes to go through the production, proofing, printing, and mailing process.
You can send people to a landing page on your website that has a URL that is specific to your direct mail campaign. You will then need your vanity URL to redirect to a tracking URL. Unfortunately, this will only be a useful measure of success if you are trying to drive traffic to your site. To learn how to do this, view this white paper by Brian Clifton explaining ways to track offline marketing. You can purchase your vanity URL here.

A trick banner is a banner ad where the ad copy imitates some screen element users commonly encounter, such as an operating system message or popular application message, to induce ad clicks.[34] Trick banners typically do not mention the advertiser in the initial ad, and thus they are a form of bait-and-switch.[35][36] Trick banners commonly attract a higher-than-average click-through rate, but tricked users may resent the advertiser for deceiving them.[37]
Answer . Go to one of the providers, such as Yahoo.com, Hotmail.com, Gmail.com, etc. and register for a free account. That is the easiest way. Then you give the address you signed up for to someone else, who uses their e-mail account to write you a message and send it to that address. You get it by logging into your account and reading new messages.. You can also sign up for a paid account at one of the same services, and your account is then stable (won't disappear if you don't sign in often enough) and you get other privileges and choices.. There are many e-mail providers. Use a search tool such as Google to look for e-mail services. You could ask your friends if they like their e-mail providers, and take their recommendations.
Hey Jonathan , enjoyed the article but it’s far fetched for startups and beginners like me who came here to see how in the first place we bring people to our website and not how we engage them or get email out of people who are already there.. getting people on your website is a bigger challenge, love your knowledge about the field is there an article which will help solve this?
Using an omni-channel strategy is becoming increasingly important for enterprises who must adapt to the changing expectations of consumers who want ever-more sophisticated offerings throughout the purchasing journey. Retailers are increasingly focusing on their online presence, including online shops that operate alongside existing store-based outlets. The "endless aisle" within the retail space can lead consumers to purchase products online that fit their needs while retailers do not have to carry the inventory within the physical location of the store. Solely Internet-based retailers are also entering the market; some are establishing corresponding store-based outlets to provide personal services, professional help, and tangible experiences with their products.[24]

Whether you’re wanting to send emails quarterly, monthly, or more often, put your email creation dates on a calendar and stick to the schedule. You’ll build momentum for yourself and your contacts. They’ll come to start expecting your emails to arrive within a certain timeframe. If you’re good about sending your emails for a while but then suddenly go dark, you’ll start to lose the momentum on both ends. Keep the bigger picture in mind when forming this schedule. If you have a busy season or other foreseen challenge up ahead, for example, you may not have the same amount of time to allot to emailing as you do right now. Take the various factors affecting your business into account, and then increase or decrease the frequency of your emails accordingly so that you can maintain consistency.
Not only is InVision's newsletter a great mix of content, but I also love the nice balance between images and text, making it really easy to read and mobile-friendly -- which is especially important, because its newsletters are so long. (Below is just an excerpt, but you can read through the full email here.) We like the clever copy on the call-to-action (CTA) buttons, too.
The big difference is that people will be giving you their contact information voluntarily. Also, you know these people value what you offer—especially if you pick a prize that is particularly desirable to your buyer persona. For example, if you own an HVAC installation business, give away a prize related to home improvement that will attract homeowners.
Every week, the folks at InVision send a roundup of their best blog content, their favorite design links from the week, and a new opportunity to win a free t-shirt. (Seriously. They give away a new design every week.) They also sometimes have fun survey questions where they crowdsource for their blog. This week's, for example, asked subscribers what they would do if the internet didn't exist.
Mobile advertising is ad copy delivered through wireless mobile devices such as smartphones, feature phones, or tablet computers. Mobile advertising may take the form of static or rich media display ads, SMS (Short Message Service) or MMS (Multimedia Messaging Service) ads, mobile search ads, advertising within mobile websites, or ads within mobile applications or games (such as interstitial ads, "advergaming," or application sponsorship).[24]:23 Industry groups such as the Mobile Marketing Association have attempted to standardize mobile ad unit specifications, similar to the IAB's efforts for general online advertising.[49]
A/B testing is trying two different techniques that communicate the same message on a small percentage of your list, seeing whether A or B performed the best, then using the better performing option when you email the rest of the list. It sounds complicated, but there are plenty of email marketing solutions out there that take all the math and guesswork out of it. (All you have to do is come up with the option A and option B you want to try.)
After that, you need to make a choice about how to construct an online presence that helps you achieve that goal. Maybe you need to set up an e-commerce site. If you’re interested in publishing content to drive awareness and subscribers, look into setting up a blog. A simple website or landing page with a lead capture form can help you start developing your brand and generating traffic. A basic analytics platform (like Google Analytics, which is free) can help you start to measure how you are tracking towards your initial goal.

Neil O’Keefe, senior vice president of marketing and content at the Data & Marketing Association, says that marketers began questioning direct mail’s endurance in 2007. That year, Statista reports that smartphone sales jumped 70% from the previous year to $8.7 billion. At the same time, the volume of mail sent through the U.S. Postal Service began to plummet: In 2006, people in the U.S. sent 213.1 billion pieces of mail, according to USPS; by 2017, they were sending 149.5 billion pieces each year, a 29.9% decline. By this point, smartphone sales had reached $55.6 billion. The price of postage and paper had skyrocketed, as did the number of internet users—everything seemed to hammer a nail into direct mail’s coffin.
The old formula for direct marketing success was mass marketing: "Mail to as many people as you can; someone has to be interested." However, paper and postage costs are always increasing, and with so much mail ending up in the trash, businesses have changed their way of thinking. Why waste money mailing to everyone when everyone is not a potential customer? You need to target the leads who will buy. That is the difference between mass marketing and target marketing.  Targeted mailing lists pinpoint your best leads.  There is less waste and a higher percentage of prospects responding to your mailing. http://www.emailvendorselection.com/wp-content/uploads/2014/12/email_drips_hobsons.jpg
When it comes to rented or purchased lists, you may come across vendors or marketers who say, "This email list is totally opt-in!" This means the people on the list opted in to an email communication from someone at some point in time -- the list provider, for example -- by filling out a form or checking a box to receive more content from that provider.

It's practically impossible to overstate the importance of direct mailing lists to the success of your direct mail program. The correct mailing list will contain your most valuable prospects. The more careful you are in analyzing and selecting direct mailing lists, the better your chances for success. There are several different categories of mailing lists available on the market today ranging in cost and appropriateness for your market. When you are considering what type of mailing list to buy consider the following three types:
Hi Jonathan, great post and well done on your prolific growth. It would be really interesting to know how many of the 56,717 subscribers came from each channel that you wrote about. Based on past experiences, I’ve seen JV launches really explode list size. My guess is that your JV partners/affiliates made up a decent chunk of these new subscribers during this period? It would cool to know what moved the needle the most. Cheers!

More recently, companies have sought to merge their advertising messages into editorial content or valuable services. Examples include Red Bull's Red Bull Media House streaming Felix Baumgartner's jump from space online, Coca-Cola's online magazines, and Nike's free applications for performance tracking.[18] Advertisers are also embracing social media[22][23] and mobile advertising; mobile ad spending has grown 90% each year from 2010 to 2013.[24]:13

Does the difference in these terms and their definitions matter? No, of course not, it's semantics! But it is interesting to see how the scope of Internet marketing vs Digital marketing has changed over time. In my books, when discussing alternative definitions, I explain that, no it doesn't really matter, but the scope and responsibility is important to make the most of managing the opportunities. So the scope of digital marketing activities should be agreed within a business and/or between a company and its agencies. The biggest difference is whether digital marketing is simply seen as about communications (online marketing) or whether it is broader, looking at underpinning marketing technology and options for new online business and revenue models.

You could use your Hotmail, Gmail or Yahoo accounts, but if you need something professional and fool-proof and want to avoid being labeled a spammer, it’s a far better idea to use an email blast program provided by a professional email marketing company such as Benchmark Email. Benchmark’s partnerships with elite consortiums like The Email Sender & Provider Coalition (EPSC) and leading delivery experts like Return Path give you the best chance of reaching a prospect’s inbox, which is a major challenge in email blast marketing. Benchmark Email even has built-in data merging features, which allow you to import contact information from different databases so you don’t need to re-enter long email lists. Besides this, you can also customize your mails in easy-to-use HTML editors before sending them to your customers and prospects.
The effort you put into building your email list is one of the best investments you can make online. Having access to the inboxes of targeted prospects means you can continue to build and nurture relationships over time, and become a trusted source of valuable industry knowledge. Then, when it’s time for your prospects to buy, you’ll be the first one who comes to mind.
If you are still interested in trying direct mail, I would suggest using USPS Every Door Direct Mail Service. With this service, you can target the specific area you are interested in sending a mailer to. If you have the budget, send out 1,000 direct mail pieces to start and see how many sales you get. It’s a good idea to include a promotion, like 15% off of your first purchase, to entice people to buy your product. If you use a code that is unique to your direct mail campaign, you will also be able to track how many sales came directly from your direct mail piece.
Most popular email marketing services offer functionality that strikes a recipient from a list once a certain number of emails to a specific recipient ‘bounced’ back as undeliverable. Don’t be overeager to remove a subscriber, though; there are valid reasons why an email cannot be delivered. Consider only removing such a subscriber after four or five “bounces”.
But before any of you young guns scoff and discount the idea of a mail marketing campaign, you might want to read through this blog entry. Direct mail, while certainly a dinosaur in the world of marketing, can still be a powerful weapon in your arsenal – if it’s done correctly and intelligently, of course. We’ll lay out a few broad tips for you to consider if carrying out a direct mail campaign. While we would still urge the majority of business owners toward a more electronic/Internet based marketing strategy, you can still get solid results from direct mail.

This ties into the second 40 of the 40/40/20 rule – now you’re probably beginning to see why that was listed up front and why it’s universally considered the gold standard when it comes to direct mail marketing guidelines. With other forms of advertisements or marketing, it is perfectly acceptable to only go after impressions – a billboard in a highly-trafficked area or a TV spot that is more of a teaser in nature can sometimes go a long way toward educating the public of your existence, which is the first step in getting them to engage. With direct mailings however, you might as well be printing cash to send out to people if you don’t have a compelling call to action to give people.
Email marketing is now a very popular offshoot of direct mail marketing (See also Email Marketing). However, it’s worth bearing in mind that 37 states now have laws regarding “spam,” or unwanted junk email. Therefore, companies that wish to maintain a positive reputation use an “opt-in” policy for marketing email, targeting only interested customers.

It is increasingly advantageous for companies to use social media platforms to connect with their customers and create these dialogues and discussions. The potential reach of social media is indicated by the fact that in 2015, each month the Facebook app had more than 126 million average unique users and YouTube had over 97 million average unique users.[27]


E-marketing is a process of planning and executing the conception, distribution, promotion, and pricing of products and services in a computerized, networked environment, such as the Internet and the World Wide Web, to facilitate exchanges and satisfy customer demands. It has two distinct advantages over traditional marketing. E-marketing provides customers with more convenience and more competitive prices, and it enables businesses to reduce operational costs. http://www.jarcreativeuk.co.uk/assets/images/Ten_steps_to_email-success.jpg
When you send messages to a purchased email list, you don’t have explicit opt-in to be emailing those subscribers. Explicit opt-in — meaning subscribers actively and knowingly gave you permission to email them (i.e. filling out a sign up form on your website) — is required for a quality list, says AWeber’s Best Practices Manager, Josh Smith. “If you don’t have explicit opt-in, you are bound to have problems,” he explains.
While it’s tempting to say that we were able to create such a massive email list all by ourselves the reality is that it impossible to get that far without the help of some friends. As an entrepreneur one of our most valuable resources is our community of peers. While it may be easy to view others in your niche as your competitors, you’ll actually get a lot of more out of your entrepreneur community if you actually view them as potential partners who can help you out. http://fredericgonzalo.com/wp-content/uploads/2017/05/email_2.jpg
Marketers need to authenticate their email to prove to ISPs that their messages are legitimate, helping to ensure delivery to their subscribers. Sender Policy Framework (SPF) verifies a brand’s identity; DomainKeys Identified Mail (DKIM) verifies the message wasn’t tampered with in transmission; and Domain Based Authentication Reporting and Conformance (DMARC) requires both SPF and DKIM approval in order to authenticate.
It’s a best practice to ask the referrer not only for a friend’s email address, but also for a full name so that the message is personalized. Most important, remember to add the referee’s full name to the email as well. By referencing whom the email content was recommended by, you gain instant credibility and will attain much higher conversion rates.
There are lots of differend types of emails. Such as... Hotmail Googlemail Yahoo Btinternet All you have to do to get an email address is to type in one of the above suggestions on the internet. Once you have got on to the page, then you either sign in if you already have an email address or create one, which should appear on a button somewhere on the page. When you have found the button to create an email, you have to put in your full name, it doesn't have to be real, and type in a password two times. It will probably look like this... First name: Second name: Your email address to customize: _____________@______.co.UK/com Alternate email address*: Postal code: Country/city: Birth year: Something like that! * an alternate email is an email which has already been created. Sometimes this is optional weahther to include it or not. You either type in a family mamber's email address. This is used for resetting your password or changing name etc. You check that email to do so. I hope i have given you the right informatuon you want!

Pop-up forms provide visitors with a quick, convenient way to share contact information and subscribe to your list while they’re browsing your site, making them a powerful tool for audience growth. They’re easy to add to your site, and they’re proven to work—our research shows that Mailchimp users have seen their list growth rate increase by an average of 50.8% after adding a pop-up form to their site. https://reallygoodemails.com/wp-content/uploads/2015/01/Have-You-Seen-Our-Top-100-Email-Marketing-Campaigns.png
Thanks for the warning re ESPs, spam traps & spam treatments Crystal. That’s a shame. Who puts the Spam trap in there & I wonder what they’re trying to achieve? The clients I have already picked up with this purchased list may save our business. As mentioned, at $250-$500 per lead through our SEO campaign, this lead acquisition rate was unsustainable. In brief, this would not be a business. But at $13.75 per lead through the purchased cold email list, those are metrics which make a profitable business. I wonder why anyone would try to block this efficiency with Spam traps? Thanks for your time to help.

Email marketing has evolved rapidly alongside the technological growth of the 21st century. Prior to this growth, when emails were novelties to the majority of customers, email marketing was not as effective. In 1978, Gary Thuerk of Digital Equipment Corporation (DEC) sent out the first mass email[1] to approximately 400 potential clients via the Advanced Research Projects Agency Network (ARPANET). This email resulted in $13 million worth of sales in DEC products, and highlighted the potential of marketing through mass emails. However, as email marketing developed as an effective means of direct communication, users began blocking out content from emails with filters and blocking programs. In order to effectively communicate a message through email, marketers had to develop a way of pushing content through to the end user, without being cut out by automatic filters and spam removing software.
A trick banner is a banner ad where the ad copy imitates some screen element users commonly encounter, such as an operating system message or popular application message, to induce ad clicks.[34] Trick banners typically do not mention the advertiser in the initial ad, and thus they are a form of bait-and-switch.[35][36] Trick banners commonly attract a higher-than-average click-through rate, but tricked users may resent the advertiser for deceiving them.[37]
developing a planned approach to reach and migrate customers to online services through e-communications and traditional communications. Retention is achieved through improving our customer knowledge (of their profiles,behaviour, value and loyalty drivers), then delivering integrated, targeted communications and online services that match their individual needs".

Just an Idea as a facebook/social friends request is slightly different than a push to read my spam email and less intrusive. the prospect has the choice and through this decision you can pretty much ascertain they are looking for what you are offering or interested in the targeted keywords your profile centres around- when you are friends start a conversation and follow up.
Your social media strategy is more than just a Facebook profile or Twitter feed. When executed correctly, social media is a powerful customer engagement engine and web traffic driver. It’s easy to get sucked into the hype and create profiles on every single social site. This is the wrong approach. What you should do instead is to focus on a few key channels where your brand is most likely to reach key customers and prospects. This chapter will teach you how to make that judgment call.
Advertisers have a wide variety of ways of presenting their promotional messages, including the ability to convey images, video, audio, and links. Unlike many offline ads, online ads also can be interactive.[18] For example, some ads let users input queries[69] or let users follow the advertiser on social media.[70] Online ads can even incorporate games.[71] https://subiz.com/blog/wp-content/uploads/2015/06/email-marketing-campaign.jpg
Focus on the reader first. You should always write your emails to address the needs of your subscribers, not yours. Offer ways to solve their problems, don’t simply talk about your products and how great they are. (This is a part that so many companies get wrong.) Ask yourself, what are the biggest pain points/struggles for my subscribers? How can I solve their current problem in this email?
Expert marketer Ramit Sethi of GrowthLab agrees with Julie about saying goodbye to the email blast, going as far as to publish a blog post entitled “Stop sending email blasts! Do this instead”. The post takes the recommendation to segment even further by suggesting “hotlists” — sub-segments of your email list that subscribers can opt into based on their interest in a specific project of yours.

Marketing emails need to be personalized to the reader and filled with interesting graphics. Few people want to read emails that are addressed "Dear Sir/Madam" -- as opposed to their first or last name -- and even fewer people want to read an email that simply gives them a wall of text. Visuals help your recipients quickly understand what the point of the email is.
Are you really willing to risk not only your email deliverability, but also the reputation of your IP address and your company? Even if you find the light after purchasing or renting email lists and decide to only email those who have opted in with your company, it'll take you months (or maybe years) to get your Sender Score up and rebuild the reputation of your IP.
Purchased lists are ineffective, and they impact everyone else who uses Mailchimp, too. If you send emails to a list of people whose contact info you bought, many of the emails will get identified as spam. Some spam filters will flag a campaign if anyone with the same IP has sent spam in the past. When you use Mailchimp, your email is delivered through our servers, so if one person sends spam, it could prevent other users’ emails from reaching inboxes. But by forbidding Mailchimp users from using purchased lists, we increase deliverability for everyone.
Consumers also face malware risks, i.e. malvertising, when interacting with online advertising. Cisco's 2013 Annual Security Report revealed that clicking on ads was 182 times more likely to install a virus on a user's computer than surfing the Internet for porn.[105][106] For example, in August 2014 Yahoo's advertising network reportedly saw cases of infection of a variant of Cryptolocker ransomware.[107]
Direct mail is a type  of direct marketing in which businesses send letters, postcards or other promotional materials to past, current or potential customers or clients. Direct mail campaigns may be targeted to either a consumer or business or both.  In many cases, the mailing is directed to a target demographic (i.e. home owners) or geographic market (i.e. a specific neighborhood). In most cases, it's mass or bulk mailing, but you can send direct mail in smaller quantities as well.
Find things that encourage people to engage. By tracking the statistics on each of your emails, you'll be able to develop concise reports about what works and what doesn't for your target audience. Take note of the specific days and times for your highest open and conversion rates. Test different tones and subject lines and see what causes your audience to read the blast. Stick to the things that your consumer tends to favor or enjoy and avoid repeating aspects of emails that do poorly according to the stats.

Paid channel marketing is something you’ve probably come across in some form or another. Other names for this topic include Search Engine Marketing (SEM), online advertising, or pay-per-click (PPC) marketing. Very often, marketers use these terms interchangeably to describe the same concept — traffic purchased through online ads. Marketers frequently shy away from this technique because it costs money. This perspective will put you at a significant disadvantage. It’s not uncommon for companies to run PPC campaigns with uncapped budgets. Why? Because you should be generating an ROI anyway. This chapter walks through the basics of how.
While almost all reputable email service providers work very hard to make sure that your emails are not blocked by major ISP’s, they can’t control whether or not your emails hit the inbox or the spam box. Although most will help you by providing a quality score to help you determine availability, getting whitelisted is the most effective way to ensure that your emails get delivered properly.
Emails triggered by milestones, like anniversaries and birthdays, are fun to get -- who doesn't like to celebrate a special occasion? The beauty of anniversary emails, in particular, is that they don't require subscribers to input any extra data, and they can work for a variety of senders. Plus, the timeframe can be modified based on the business model.
