Email validation
Bounces cost more than you think.
Every invalid, dead or risky address is a small hit to your sender reputation. Enough bounces and inbox providers start treating all your mail with suspicion, so even your good contacts stop seeing you.
Spam traps, abuse and do-not-mail addresses are held back and never imported. Catch-all and unknown addresses are flagged, because they carry some bounce risk.
How it works
From a risky purchased list to a clean, sendable one.
Upload your list
Import a purchased or cold CSV, or point us at a list you already have in FlipSend.
Every address checked
We verify each one — valid, invalid, catch-all, risky, or a known spam trap.
Risky addresses held back
Spam traps, abuse and do-not-mail addresses are flagged and never imported.
Import the clean list
Bring in only deliverable addresses — and validation runs again at the point of send.
Protect your reputation
Never send to a dead or risky address, so providers keep trusting your mail.
Cut your bounce rate
One of the fastest ways to improve deliverability across everything you send.
Stop wasting credits
Addresses that were never going to arrive do not consume your send volume.
A safety net at send
Validation also runs at the point of send, at no extra charge.
