the problem

EVERY LIST COLLECTS DEAD WEIGHTduck

Typos at signup. Inboxes that quietly died. Disposable addresses from people who never meant to hear from you. Keep sending to them and mail providers notice. At first your bounces climb, then your good emails start landing in spam. Let's help you prevent that.

what we catch

SEVEN KINDS OF GRIMEduck

Invalid addresses

Mailboxes that don't exist. The classic bounce.

Disposable emails

Ten-minute inboxes. Gone before your welcome email.

Spam traps

Bait addresses that torch your reputation on contact.

Typos identified

gmial → gmail. We suggest the fix, you keep the subscriber.

Catch-alls

Domains that accept everything and confirm nothing.

Role accounts

info@, sales@. Deliverable, but nobody owns them.

Duplicates

One person, one email. Your stats will thank you.

…and it all happens in one pass ✦
us vs the rest

HOW ARE WE DIFFERENT?

Cheaper cleaners check that an address exists. We check that it is safe to send to. One spam trap gets your domain blocked, and that does not cost you one campaign: it hamstrings every campaign after it until your reputation is rebuilt, and that takes months. That is what the difference in price buys.

A handshake with the mail server. Nobody on your list hears from us.

3

Seen by you only

Verdicts land in your account. Nothing is copied out.

4

Deleted on schedule

7, 30 or 90 days, your call. Or one click, right now.
