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.

FAQ

Common questions about Acelle Mail + Capsule

Is there a pre-built Acelle Mail + Capsule automation?

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

Does this require a pre-built Acelle Mail or Capsule connector?

No. The Agent works whether or not Acelle Mail or Capsule 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.

How do Capsule and Acelle Mail work together to nurture leads?

When a new lead is added in sales or marketing, prospect information is automatically synced between both platforms so your marketing team can launch targeted email sequences immediately.

Will customer unsubscribe status sync across both tools?

Yes, if a contact opts out or updates their preferences, their profile can be automatically updated across both Capsule and Acelle Mail to maintain compliance.
