Seven ways a bad email slips past you
"disposable": trueCatch throwaway signups instantly
We track 200,000+ disposable domains — updated daily — so fake signups get blocked before they waste a single credit.
"relay_domain": true"provider": proton.meSee through email masks
Firefox Relay, Apple Hide My Email, SimpleLogin — forwarding services are everywhere. We expose them so you can ask for the real address.
"mx": trueConfirm the mailbox exists
No MX records, no mailbox. We check DNS in real time so you never send into a void and burn your sender score doing it.
"public_domain": trueKeep B2B forms business-only
Flag Gmail, Yahoo, and Hotmail automatically. Enforce work-email policies on your forms without writing custom rules.
"did_you_mean": "gmail.com"Rescue typos before you lose the lead
gmial → gmail. hotmai → hotmail. We catch the typo and suggest the fix in real time, so a mistype doesn't cost you a real signup.
"role_account": trueSkip the inboxes nobody reads
info@, support@, hello@ — nobody converts from a shared inbox. Flag role accounts and focus your follow-ups on real people.
test@company.xyzBlock bad format before it breaks anything
Invalid TLDs, missing @ symbols, broken structure — we catch RFC violations at the edge so your database stays clean.

What teams say
“We cut our bounce rate by 94% in the first week. The API took less than an afternoon to wire up.”
SCSarah Chen
CTO, MailFlow
“The credits-never-expire model is the reason we switched. We validate in batches, not continuously — so paying monthly made no sense.”
MRMarcus Rivera
Head of Growth, Launchpad
“Cleaned 80,000 contacts before our Q4 campaign. Saved us from sending into a list that was 30% garbage.”
PSPriya Sharma
Marketing Director, ScaleUp
