Take the email below from Paperless Post, for example. I love the header of this email: It provides a clear CTA that includes a sense of urgency. Then, the subheader asks a question that forces recipients to think to themselves, "Wait, when is Mother's Day again? Did I buy Mom a card?" Below this copy, the simple grid design is both easy to scan and quite visually appealing. Each card picture is a CTA in and of itself -- click on any one of them, and you'll be taken to a purchase page.
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.
Email marketing has evolved rapidly alongside the technological growth of the 21st century.

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.

However, the key to success is to think through the process during the build out and to monitor the program carefully for the first several months in order to optimize it. We'll discuss auto responders throughout the remainder of this book when talking about email design, implementation, tracking and optimization.

3. Email converts better. People who buy products marketed through email spend 138% more than those who do not receive email offers. In fact, email marketing has an ROI of 3800%. That’s huge! And if you are wondering if social media converts even better, think again: the average order value of an email is at least three times higher than that of social media.
