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.


The best time to send an email blast depends a little on the best time you think your recipients would like to receive it. Most business contacts receive an average of 75 emails per day. To make sure they have the time to review (and hopefully, read) your email, try to have your email blast arrive on Tuesday Mornings between 8am and 11am. Mondays (especially after holidays) is typically a day where most contacts are catching up on email from the weekend. Fridays are difficult, as most contacts are wrapping up work from the week and may not have the time to look at your message. Even if they do find time to read it, they may have forgotten about you, and your message, by the next Monday. If Monday is a holiday, time your email blast to arrive on a Wednesday Morning after the holiday. Mornings are best as most people are planning or finalizing their day in the mornings. This gives them more time to react to your email message that same day. Afternoons and evenings are typically too late in the workday to encourage immediate action.
The most advanced email marketing services offer custom workflows where you can specify triggers based on actions (such as opening an email or making a purchase) or on inaction (such as ignoring emails). With these services, you can also set up a series of emails (such as tutorials) to be sent to segments of users, and you can pause or stop a campaign at any time. You can also move contacts into new segments once they have completed tutorials.
Testimonials – If you work with contractors or freelancers, you can reach out to them to offer your testimonials in exchange for a link. Moreover, if you are using consultants’ or specialists’ services, you can also do the same as you do with contractors. Lastly, if there are customers who are happy with your product or service offering and they do not mind you linking to their site, this could be a good opportunity for your business.

Online banner advertising began in the early 1990s as page owners sought additional revenue streams to support their content. Commercial online service Prodigy displayed banners at the bottom of the screen to promote Sears products. The first clickable web ad was sold by Global Network Navigator in 1993 to a Silicon Valley law firm.[16] In 1994, web banner advertising became mainstream when HotWired, the online component of Wired Magazine, sold banner ads to AT&T and other companies. The first AT&T ad on HotWired had a 44% click-through rate, and instead of directing clickers to AT&T's website, the ad linked to an online tour of seven of the world's most acclaimed art museums.[17][18]


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.

Understand the statistics. Click-through rate or CTR is how often customers click on links contained in your email. There is also a conversion rate, which tracks how many people took action after clicking your link, as well as a rate for how many people opened and read your email. Many email blast software will have these metrics built in. Do not make things in the email blast confusing or complicated as it can prevent people from taking action or even reading the blast.
Scammers can take advantage of consumers' difficulties verifying an online persona's identity,[98]:1 leading to artifices like phishing (where scam emails look identical to those from a well-known brand owner)[99] and confidence schemes like the Nigerian "419" scam.[100][101][102] The Internet Crime Complaint Center received 289,874 complaints in 2012, totaling over half a billion dollars in losses, most of which originated with scam ads.[103][104]
Particular groups of customers can be targeted or even individuals. Offering individual customers special deals on merchandise and/or services on the customer's birthday, for instance, is one example of email marketing personalization. (A restaurant might send an email to customers on their birthday offering 50% off an entree,) Email marketing helps a business develop and maintain a relationship with a customer over time that hopefully results in increased sales and increased customer loyalty.
