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).
When it comes to deciding how to craft that perfect subject line, there appears to be really only one area to avoid: the subject line of 60 to 70 characters. Marketers refer to this as the “dead zone” of subject length. According to research by Adestra, which tracked over 900 million emails for its report, there is no increase in either open rate or clickthroughs at this 60-to-70 character length of subject line.
Dynamic segmentation – As alluded to earlier, you can’t just send out a generic message to everyone on your list. While basic demographic data can be used to segment your list, that’s far from taking the dynamic approach. Automation tools can help you segment your list as they go through the funnel, allowing you to send personalized messaging depending on their actions and behaviors.
