The biggest issue I have yet to resolve is the majority of clients I work with have customer lists in the the THOUSANDS, but have never embraced email marketing. Through personal experience with several of the platforms listed here they will not let you load your current customer list and start emailing. Even if the lists are validated and cleaned through a source like NeverBounce. With the new GDPR rules, they only want emails that have current, ongoing engagement. So in other words, even though you have been in business for years and have a list of current emails from current and past customers, you cannot load them in to these platforms with any success. This makes it very difficult for legacy businesses that now want to start communicating with all their prospects and customers.
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.

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.
I very much enjoyed your article. I currently send out a daily news blog to about 3,100 recipients. The program I use is not on your list, and I am shopping around for someone new. My biggest challenge is spam filters blocking my message. This seems to happen because of the appended coding that tracks click-throughs. However, it may also be because of my send-frequency. I’ve also discovered that the domain of the company I’m using has found its way to gray lists, and I often have to get my subscribers to add various domains to their safe-sender/white lists. It’s frustrating. So, my long winded question is – do different providers have varying ‘deliverability’ ratings? (PS – I use Mail Chimp on behalf of several small non-profits I do work for, and so am familiar with their services – but am curious about the others).

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). He claims that this resulted in $13 million worth of sales in DEC products,[2] and highlighted the potential of marketing through mass emails.
Effective email marketing campaigns are designed for all devices on which users can read their emails -- desktop, tablet, and smartphone. Email campaigns that are designed for mobile devices are especially important -- a quality known as "responsive design." In fact, 73% of companies today prioritize mobile device optimization when creating email marketing campaigns.
Loved reading this! Which of these would you recommend so that I could set myself reminders on certain clients so that I can follow up with them in the future? I feel like I am doing a lot of extra steps that I might not have to do if I was using an actual marketing software. I am in the very beginning stages of getting my business out there and I would like to follow up with potential clients down the road with an email… is this a possibility or should I just keep using my excel spreadsheet!? 

This rule might sound like bad news for your email marketing campaign, but it can actually improve your open and clickthrough rates. Limiting your subscriber list to just those who specifically asked to join you will ensure only the most interested people are receiving your messages. This maximizes the chances that you'll convert readers to qualified leads as a result of an email send.
In 2002 the European Union (EU) introduced the Directive on Privacy and Electronic Communications. Article 13 of the Directive prohibits the use of personal email addresses for marketing purposes. The Directive establishes the opt-in regime, where unsolicited emails may be sent only with prior agreement of the recipient; this does not apply to business email addresses.

Everyone's busy and their inbox is already full. Why add to the problem with a longwinded email? People generally like short, concise emails better than long ones because concise emails have an obvious focus. Plus, when your users are scanning through all their emails in a short amount of time, they're more likely to find the overall message before deciding to take any action.
Professional email marketing software offers you the tools to track results so that you can better understand customer behavior. This allows you to set customized messages, as well as to A/B test your messages so that you can constantly fine-tune your marketing campaigns. Let’s say, for instance, that you want to find out which is the best auto-responder for your high-rolling segment of customers. You can set different options, compare auto-responders, and make an informed decision. Sendinblue also features marketing automation, and its wealth of plugin capabilities make it easy to maximize your email campaign.
