Formstack is one of the easiest ways to build custom forms that let you collect data your way.
Catch missing merge details and report the contacts skipped during sends.
Your mail merge goes to eligible contacts from your campaign mailbox, with a tally of sends and contacts needing attention.
Apply team UTM rules to each link request.
Get a tracking link by email with your UTM rules applied, or a clear note about what you need to fix in the form.
