FAQ

Common questions

Can Knit build “Turn website form submissions into newsletter subscribers” between SendMails and Passion.io?

Yes — describe it in the box above and Knit's Integrations Agent researches SendMails and Passion.io's public API docs (or your own uploaded docs) and builds a working workflow, whether or not either app already has a pre-built connector.

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