FAQ

Common questions

Can Knit build “Send immediate welcome messages to new marketing leads” between to.co and Gmail?

Yes — describe it in the box above and Knit's Integrations Agent researches to.co and Gmail'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.

How long does it take to build?

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

What's the most common Marketing + Email automation?

Adding a new contact to a campaign in to.co whenever they're added to a list in Gmail, or logging a reply from Gmail back onto that contact's record in to.co.

Does this risk double-emailing the same contact?

No — the Agent can be configured to suppress a contact from one tool's send the moment they're active in the other, avoiding duplicate outreach.
