Bounce rates kill reputation
A bounce rate above 2% signals to ISPs that your list is unmanaged. Your sender score drops and every future email suffers.
Email Verifier · Mox Suite
Every addressverified.Every send protected.
Dead addresses destroy your bounce rate and kill your sender reputation. Moxcheck verifies every contact in seconds so you only send to real people.
The problem
Bad lists cost more than
you think.
You're paying to send to nobody
Every dead address in your list costs you money: ESP charges, wasted sequences, and sales time chasing contacts that don't exist.
Verification takes seconds, not hours
Most teams skip verification because it feels complicated. Moxcheck does it in bulk, so you can upload a CSV and get results in under 60 seconds.
