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 Poptin + Unisender

Is there a pre-built Poptin + Unisender automation?

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

Does this require a pre-built Poptin or Unisender connector?

No. The Agent works whether or not Poptin or Unisender 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 happens when someone completes a survey in Poptin?

You can automatically add or update their contact profile in Unisender and assign them to specific mailing lists based on their survey answers.

Can email engagement in Unisender initiate a survey request?

Yes, when a contact clicks a specific link in Unisender, you can automatically add them as a respondent or send them a transactional email linking to a relevant Poptin form.
