FAQ
Frequently asked questions
- How do I add verification status to Klaviyo profiles?
- Import results with a custom property like "email_verified" that you can use for segmentation.
- Can I automate verification for new subscribers?
- Yes. Trigger on new-profile creation and call https://api.kawaa.com/v1/verify — from your own code, or from a generic HTTP step in Zapier or Make — then write the result back via Klaviyo's API. Kawaa is not published as an app on Zapier or Make yet, so the generic HTTP step is the route.
- Should I suppress or delete invalid emails?
- Add invalid emails to your suppression list to prevent future sends while maintaining the profile data.
