Klaviyo email verification options
1 min
When mailfloss finds an invalid email in Klaviyo, the Cleanup tab decides what happens. The setting applies to every list in the connection, and you can change it any time.

- Ask me first. The safest option. mailfloss lists invalid emails in Waiting for you, and nothing changes in Klaviyo until you decide.
- Report only. mailfloss emails you the results. Nothing changes in Klaviyo.
- Update a field. mailfloss sets profile properties in Klaviyo, so your segments can exclude invalid emails. This is reversible. Available on the Pro plan or as an add-on.
- Unsubscribe. The recommended option. The profile is suppressed in Klaviyo and stops receiving campaigns. You can resubscribe it in Klaviyo at any time.
- Delete from Klaviyo. Removes the profile for good. In Klaviyo, Delete removes the profile and its history from your whole Klaviyo account, not just this list. Before Delete turns on, mailfloss shows what your last run would have deleted and asks you to confirm.
Typo Fixer works alongside every option: when an address has a common typo, such as gmial.com, mailfloss can correct it on the profile instead of treating it as invalid.
