FAQ

Common questions about Ninja Forms + MailUp

Is there a pre-built Ninja Forms + MailUp automation?

Not yet, but Knit's Integrations Agent can build one — describe what you want and it researches Ninja Forms and MailUp's public API docs (or your own uploaded docs) and builds a working automation.

Does this require a pre-built Ninja Forms or MailUp connector?

No. The Agent works whether or not Ninja Forms or MailUp already has a pre-built connector in Knit's catalog — it researches the real API surface either way.

How long does it take to build?

Minutes to build a first working version, not weeks — you test it against real data before it goes anywhere near production.

What happens when someone completes a survey in Ninja Forms?

You can automatically add or update their contact profile in MailUp and assign them to specific mailing lists based on their survey answers.

Can email engagement in MailUp initiate a survey request?

Yes, when a contact clicks a specific link in MailUp, you can automatically add them as a respondent or send them a transactional email linking to a relevant Ninja Forms form.
