What it does
If you collect signups with NEX-Forms and send newsletters with Mailster, moving contacts between the two can turn into a chore. Exporting entries, cleaning them up and importing them into a list takes time and invites mistakes. This add-on removes that step. New contacts captured by your forms go straight into the Mailster list you pick, which keeps your mailing lists current without any manual data entry on your part.
The add-on works through field mapping. You decide which form fields line up with which Mailster list columns, and there is no limit on how many columns you can map. That means names, email addresses, preferences and any custom details you ask for can land in the right place in your subscriber data. It suits newsletter signup forms, event registrations and other form-driven ways of gathering contacts, and it runs on responsive forms that work across devices.
Best for
- Sites using NEX-Forms and Mailster together
- Bloggers and businesses growing newsletter lists
- Event organizers collecting registrations into mailing lists
