Grow a Klaviyo list and trigger flows from every submission.
The AntForms Klaviyo integration subscribes respondents to your chosen list, fires a custom event, and can route different respondents to different lists based on their answers - all via native OAuth.
Three patterns AntForms customers ship most often, each reachable from the Integrations tab in under two minutes.
Grow your Klaviyo list with every submission
Every form submission upserts a Klaviyo profile and subscribes it to your chosen list, ready for your existing flows and campaigns.
Route respondents to different lists by answer
Use routing rules to send a submission's profile to specific Klaviyo lists based on their answers - a respondent can match more than one rule and join every list that applies.
Trigger Klaviyo flows from a custom event
Each submission fires a custom Klaviyo event (default: AntForms Submission), so you can build flows that react to a form fill the same way you would any other Klaviyo event.
