### Selecting a Group Groups are like tags, and if you have any, they'll be listed in this section.

Select One or More Groups for Your Subscribers

You can also add your own Groups (tags) and refresh them if they are updated elsewhere. ### Selecting a Field (Custom Fields)

MailerLite Fields are Shown in the Custom Fields Section

With Custom Fields, you can map all of your MailerLite fields to the various comment fields available.

You're also able to refresh your Fields and add in new ones. If you need to delete any fields, I recommend doing so in the MailerLite interface.

{% hint style="info" %} All Fields created using this integration will have the type of 'text.' {% endhint %} ### Set up Default Options You can also set the sign-up label, whether to enable double-optin, and to have the signup checkbox enabled or disabled by default.
