In this video, I'll explain the difference between groups and segments in MailerLite.
Groups are used for when people join your signup form, so you know where they're coming from (e.g. from the main page pop-up).
Segments are dynamic and automatically updated. The segments change based on the conditions you set.
Let's first go to Forms. I created a pop-up called Weekly Newsletter and activated it. When you click on the title, you'll see an overview. Under Subscribe to groups, you'll see that every new subscriber is automatically added to the group Weekly Newsletter. When you click on the tab Groups, you'll see all your groups.
When you click on Campaigns in the upper menu, you'll navigate to all your campaigns. For this example, we'll look at a retargeting campaign. Click on Recipients and you'll see all the selected subscribers (either a group or segment). For this newsletter, I have 1 group selected who should receive my newsletter and a couple of groups that I want to exclude. To save these settings in an easy way for a future newsletter, you can use segments.
Go to Subscribers and then click Add segment. Give it a name (in this case, Weekly Newsletter). First, we want to add the condition "Group belongs to Weekly Newsletter." You can add as many groups as you'd like. For all the groups that you'd like to exclude, you can use the condition "Does not belong to." Finally, save your changes.
You can also create segments based on location, time zone, whether someone did/didn't open a specific newsletter, signup source, open rate and much more.
For the conditions, you can use And and Or. This means subscribers need to adhere to all conditions or only the upper or lower condition(s).
The next time you send a newsletter, you don't need to manually include and exclude all your different groups. Instead, you can use the segment you just created.
