Very well written article! Thanks for sharing!!! Just that I would add another tool to this list- intellyMail.com. It is really one of the best email marketing tools that I have come across. intellyMail eliminates the need of manually sending bulk emails through an automated process, thus saving you time and money, besides helping you generate leads
There are lots of ways to buy an email list, but none of them will actually benefit your campaign. Why? Since the owners of these email addresses didn't explicitly agree to receive content from you, there's no telling how interested they are -- or if they're even a fit for what you have to offer. A bought email list is also in violation of GDPR (we'll talk more about this in just a minute).
Last but absolutely not least – Aweber, GetResponse and Vertical Response all have solid Privacy and Anti-Spam Policies in place that are 100% trustworthy as of Dec 2016 at last check. All companies change their policies though so always check the final print (toward the bottom) and make sure you know exactly what you and your clients have “Opted In” for.

Support availability is an important aspect to consider any time you purchase online marketing services, especially if you are a novice. Check if the email marketing software provider you plan to use offers 24/7 support via phone, chat, or email as well as comprehensive documentation. This is especially important when your marketing campaigns are time sensitive. You don’t want to end up not sending out your Black Friday newsletter just because of a technical glitch you weren’t able to fix.
Moonmail is great platform that utilizes Amazon SES  – which means you are only paying for what you send (vs. subscribers in your account), making it at cost effective solution for small businesses. With a powerful drag and drop editor, deep analytics, and built-in heatmaps (so you can see what content is working) all under a clean and easy-to-use interface, it’s a excellent choice to scale your email marketing needs.

Another way to extend the clicks on your email beyond its shelf life is to prompt your audience to forward the offer. The folks at Litmus found that the most forwarded emails were 13X more likely than the typical email to include “Share With Your Network” calls-to-action. By including forward-to-a-friend (or social sharing links, as we discussed above), you put it in recipients' minds to share.
