As a growing business, you may also be looking for a CRM solution, and you'll find that the more advanced email marketing services have begun to crossover into CRM. It makes sense: Both types of software deal with managing and communicating with customers. A handful of these services are one-stop shops, either offering both email marketing and CRM out of the box or as add-on services.
Write a compelling subject line. The subject of your email will be the first thing that people will see when viewing it. Because of the immense amount of spam that exists, it's important that you draw the recipient in enough so that they open the message. The subject line should invite the reader to some benefit or include a sense of urgency which requires action. Avoid cliche marketing terminology like "act now" or "free limited offer" as these subject lines can make recipients feel suspicious and turned off. Your subject line should be 50 characters or less.
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)
