Sendinblue email verification options

Sendinblue email verification options using mailfloss

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

Before explaining the five options, make sure you have properly connected Sendinblue 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 Sendinblue account.

Here’s a screenshot of the five options you have with Sendinblue email validation:

The first option “Manually decide action on invalid 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 invalid emails” will unsubscribe the contact from Sendinblue and remove the contact from the lists it belongs to. This action is irreversible. You’ll see the contact in Sendinblue in red and marked as blacklisted from receiving emails.

The third option “Delete invalid emails” is also irreversible. Once deleted, the contact is gone from the lists it belongs to inside Sendinblue.

The fourth option is a little more advanced and intended for advanced users. It will update custom fields inside of Sendinblue, which you can use to sync with your other databases and CRMs.

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 Sendinblue 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 Sendinblue account and nothing more.
