Next up is building an email newsletter. The best services offer several ways to do this; you can import your own HTML, start from scratch, or use a predesigned template. Most of these services have drag-and-drop UIs that let you choose exactly the elements you want to include, as well as image libraries in which you can store assets such as your logo or company photos. Tools that let you test your emails for spam are also essential since there are some seemingly innocuous terms that may send up red flags and drop all of your hard work into your subscribers' junk folders or, worse, get your emails banned before they ever reach their recipients.
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).
