FAQ

Common questions about Klaviyo + AddEvent

Is there a pre-built Klaviyo + AddEvent automation?

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

Does this require a pre-built Klaviyo or AddEvent connector?

No. The Agent works whether or not Klaviyo or AddEvent 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.

Can event sign-ups start automated marketing campaigns?

Yes, registering for an event in AddEvent can automatically create a contact in Klaviyo and enroll them in a pre-event email series.

How can marketing activities register users for events?

When a lead enters a workflow or updates in Klaviyo, you can automatically register them as an attendee for an upcoming session in AddEvent.
