Stop letting dead addresses wreck your sender reputation.

MailVeri verifies every email address before you hit send — so your campaigns reach real inboxes instead of bouncing into spam folders and dragging your domain down with them.

The challenge

Every bounced email is a small tax on your reputation. Send to enough dead addresses, spam traps, or typo'd domains and mailbox providers quietly start routing you to the junk folder — even for the customers who do want to hear from you.

Most teams don't notice until open rates have already cratered and a quarter of their list is unreachable. The usual fix — manually scrubbing exports in a spreadsheet — doesn't scale past a few hundred rows and misses the dangerous stuff entirely.

What we built

We built MailVeri as a verification layer you can drop in anywhere: a real-time check for signup forms and a bulk cleaner for existing lists.

Each address runs through layered checks — format, domain, mailbox existence, plus spam-trap and catch-all detection — and comes back with a clear verdict, not a vague score.

It's fast enough to verify at the moment of capture and cheap enough to run across an entire list, so checking becomes the default instead of an afterthought.

How it works

Real-time API

Validate addresses at the point of capture so bad data never enters your list in the first place.

Bulk list cleaning

Upload a CSV, get back a scored, segmented file — deliverable, risky, and dead, clearly separated.

Trap & catch-all detection

Flags spam traps and catch-all domains that quietly torch sender reputation.

Layered checks

Syntax, MX, and live SMTP probing combine into a verdict you can actually act on.

The result

Teams using MailVeri before a send protect the sender reputation they've spent years building — cleaner lists, fewer bounces, and more messages landing where they belong.
