Klaviyo email verification options using mailfloss

If you’re using mailfloss for Klaviyo email verification, you have four options at your disposal.

Before explaining the four options, make sure you have properly connected Klaviyo to mailfloss. You only need to do this once and from then on mailfloss will be able to automatically perform email verifications for the connected Klaviyo account.

Here’s a screenshot of the four options you have with Klaviyo email validation:

The first option “Manually decide action on bad emails” will display emails deemed invalid so you can decide an action on them, like so:

With manual mode set, you can later decide to delete, unsubscribe, ignore, or report the status as incorrect for all contacts mailfloss determined as invalid.

The second option “Unsubscribe bad emails” will unsubscribe the contact from Klaviyo and remove the contact from the lists it belongs to. This action is irreversible. You’ll see the contact in Klaviyo under “List Suppressions”.

The third option is a little more advanced and intended for advanced users. It will update custom fields inside of Klaviyo, which you can use to sync with your other databases and CRMs or do whatever you please with them.

The final option is “do nothing”. Basically, all this option does is send you an email report of the latest floss session, but doesn’t actually change anything inside of Klaviyo or mailfloss. This is most like boring, traditional email validation services, but is useful if you just want a report of the email verification statuses determined by mailfloss for the connected Klaviyo account and nothing more.
