Every list has its own web sign-up form, however, one or more lists may have several segments. You can create segments after the subscribers are already on the list based on their needs, but you can be one step ahead if you give the new subscribers an option to choose which segments they want to be in.
Adding Segments in your Sign-up Form
Adding segments is not much else than adding new value for every subscriber in the list. This can be used, for example, to subscribe to your newsletter in a particular language.
Steps you have to take to add segments in your sign-up form:
STEP 1 Go to web form section and choose a list.
STEP 2 Add a new field to your list by clicking on "select form fields". Choose a "checkbox" type and define the options. This should be a required field.
STEP 3 Go to segments section and create a segment for each given option (in this example language). Do not forget to enable auto-update.
Now every new subscriber will have an option to choose a language and will be automatically added to a particular segment. You can now send a content that is relevant to the subscriber.
