A significant element of email marketing is relationship. Does a recipient trust you? Does a recipient even know who you are? When an email jumps the gun by forcing familiarity too soon, the personalization comes across as skeevy. Intimacy is earned in real life, and it would appear to be the same way with email. Take this example from my inbox; no one has called me lowercase kevan l lee in years.
Great companies are always evolving, and your customers expect to experience change. What they don't expect (because too many companies haven't lived up to this end of the bargain) is to be told about those changes. That said, this email from ModCloth serves as a refreshing change of pace. If you're going to change the way you communicate with a lead or customer, give them clear, fair warning so, if they aren't on board, they can make the necessary adjustments to keep their inbox clean.

Minimal risk: Some top marketers expect to burn through $10,000 of advertising budget before even knowing if they can make a campaign profitable. (Nope, that’s not an exaggeration. But I’d usually aim for a few hundred dollars—not thousands.) With email marketing, the costs are much, much lower. A simple email marketing software like AWeber is very affordable even if your business isn’t a huge success, yet. And even if you go with something advanced like Infusionsoft, you’re still far away from the kinds of investments many other marketing tactics require. Sure, email marketing and advertising aren’t directly comparable (advertising is mainly used to reach new prospects). But you get the point.
Transactional emails (like an order confirmation) are best sent immediately after the purchase is made. Lifecycle emails—which are sent based on specific behaviors a customer exhibits—require a little more testing to get right. The best time to send an abandoned cart email, for example, can vary based on the reason for abandonment and your strategy for recovering those orders.
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.
Vertical Response is great email marketing tool for creating professional newsletters as it offers tons (over 700) of designs for email newsletter templates. It also has a lot to offer in terms of editing and integrations (e.g. various CRM software, survey software and more). Additionally, users can create landing pages, conduct A/B testing (e.g. subject line performance), test emails using the Vertical Response test kit and much more.
Sample review: Optinmonster “has various forms you can embed on your site to help with email conversion but one of the most interesting ones is the popup. You can set the popup only to appear on ‘exit intent’.  This means that your website visitor can browse all they want and when they are about to exit the website you can have a popup appearing tempting the visitor to leave their email address.” — RazorSocial (World)
Use your real email signature: Just like using a real reply-to email address, you want to use real contact information within the email and the best way to do that is to include your contact details in the email signature. Giving your readers the opportunity to contact you or connect with you online is a great way to be personal and build a relationship with them.
