Litmus is an email marketing tool that is primarily focused on testing and tracking your emails. This software offers a web-based drag-and-drop editor so marketers can easily build their own emails. They also have a large selection of customisable templates to choose from. Once emails have been built, previewed (in mobile/desktop) and sent out to your contact list(s), you can make use of their detailed engagement summary reports (including open rate, deletions, how long email was open, geolocation and more).

Give people a way to avoid more emails about the same offer. If you do a concentrated promotion for something, you might send lots of emails about it in a short time. Give people the option to avoid future emails about the offer. Just add a link to the end of the emails (e.g., “If you’re sure you’re not interested in [ offer ], click here, and I won’t send you any more emails about it this year.”). That way you won’t annoy people who aren’t interested in the offer now. You could argue that some of them might buy if they saw all the emails. Well, if you’re only interested in this month’s sales, send as many emails as you can. I just assume you want to have someone left on your list for next month.
While email marketing ROI is higher than that of social media, you’d be remiss if you’re not combining both. While keeping your brand top of mind is an obvious benefit of using email and social, the crucial data you can derive from both enables you to hyper-personalize your messaging and content. This makes integrating both an integral part of your social media strategy and vice versa.
