Establishment of customer exclusivity: A list of customers and customer's details should be kept on a database for follow up and selected customers can be sent selected offers and promotions of deals related to the customer's previous buyer behaviour. This is effective in digital marketing as it allows organisations to build up loyalty over email.[22]
You work with a list provider to find and purchase a list of names and email addresses based on demographic and/or psychographic information. For example, you might purchase a list of 50,000 names and email addresses of people who live in Minnesota and don't have children. There are several sustainable ways to use email marketing to grow your business. This isn't one of them.
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]
Set your target audience. Audiences can be split up in a variety of ways including gender, age, geographic location, or buying habits. Before you send your blast, you want to make sure that you can segment people into different lists so you can target your blasts to the right people. Consider what demographic you want to target, and what they will need to fulfill your call-to-action.

If someone didn't ask to hear from you yet, it doesn't mean they won't want to hear from you later. It's your job to prove to them -- through helpful content and valuable offers -- that they should stay up to date with your company via email. If you force your email content on anyone too early, even if you know in your bones they're a great fit for your products or services, you risk preemptively losing their trust and their future business.
With the GDPR now governing all email correspondence across Europe, adding an opt-out option to your email template no longer cuts it. Under this act, you must have explicit consent from your contacts to send them emails. Explicit, in this case, means the checkbox a person must click to opt in to an email subscription isn't pre-checked when they see it on your website. And when you buy your email lists, the people on it haven't been given this option -- making you non-compliant with GDPR before you send your first email.
 2. Select recipients based on a list, tag, or saved filter. For example, you may add the subscribers of your weekly newsletter by adding all supporters with the tag “weekly newsletter.” Alternatively, you may choose “All” and select all supporters in your nation, or all prospects. Remember that it is good practice to segment your email list in order to increase your email deliverability.
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]

Another collection method happens when list vendors buy emails lists from industry trade shows (or other events) where people give their info during the registration process. This is not the same thing as folks who signed up with you, directly, at your trade show booth! This is where list vendors purchase the entire registration list, from the trade show, itself.
The fact is, a significant percentage of millennials like mail. It has a built-in emotional response factor. Gallup reported that 36% of people under the age of 30 look forward to checking their mailboxes every day. What’s more, 95% of 18-to-29-year-olds have a positive response to receiving personal cards and letters. Notably this generation will wield a combined $1.4 trillion in spending power by 2020, as reported by Accenture.

Most of the article really talks about how to successfully get an email of a person who has already landed on your landing page/podcast page/affiliate/blog etc. but how to get those people there in the first place is a bigger challenge. Also, one of the ways you can include in your list is by offering free tools/widgets. For example, OpenSiteExplorer by Moz is a great example. Evergreen and very useful for the target audience.
Many laws specifically regulate the ways online ads are delivered. For example, online advertising delivered via email is more regulated than the same ad content delivered via banner ads. Among other restrictions, the U.S. CAN-SPAM Act of 2003 requires that any commercial email provide an opt-out mechanism.[108] Similarly, mobile advertising is governed by the Telephone Consumer Protection Act of 1991 (TCPA), which (among other restrictions) requires user opt-in before sending advertising via text messaging.

Have a clear purpose for the blast. Email blasting customers or partners is not an arbitrary task. Each blast should have a concise purpose before you begin to draft it. Determine what you're trying to deliver and how you want the recipients to react to the email. The blast's purpose could be enticing customers to purchase something, updating employees on a new project or initiative, or a newsletter to recap the month's events. Once you determine the purpose of the blast, you can work on making the message more clear to your recipients.[1]
