Why verify before the send

Sending to invalid, risky, catch-all, or disposable addresses spikes your bounce rate and erodes sender reputation. A verification gate before the Drip step removes that risk automatically — only deliverable addresses continue, the rest are flagged.

The workflow

BillionVerify — verification sits right before the send.
