Amazing Product With Exceptional Support from the team. By using Knit we managed to speed up our development by orders of magnitude.

Seamless integration experience. Well-documented, self-explanatory APIs, and excellent service and support.
Easy to integrate. Knit's dashboard is intuitive for setting up and testing integrations, and the sandbox is extremely useful during development.
Knit shipped a brand-new Timesheet API in a week and handed us a ready-to-use NetSuite sandbox. That velocity is priceless when you're running payroll in 40+ countries.

Common questions about Waitlist + Customer.io
Is there a pre-built Waitlist + Customer.io automation?
Not yet, but Knit's Integrations Agent can build one — describe what you want and it researches Waitlist and Customer.io's public API docs (or your own uploaded docs) and builds a working automation.
Does this require a pre-built Waitlist or Customer.io connector?
No. The Agent works whether or not Waitlist or Customer.io 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's the most common Marketing + Email automation?
Adding a new contact to a campaign in Waitlist whenever they're added to a list in Customer.io, or logging a reply from Customer.io back onto that contact's record in Waitlist.
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.
