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 SMTP.com + CallRail
Is there a pre-built SMTP.com + CallRail automation?
Not yet, but Knit's Integrations Agent can build one — describe what you want and it researches SMTP.com and CallRail's public API docs (or your own uploaded docs) and builds a working automation.
Does this require a pre-built SMTP.com or CallRail connector?
No. The Agent works whether or not SMTP.com or CallRail 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.
