Free email list cleaner. Upload a CSV, cull the bad emails, export clean. No credits, no catch.

We built MailCull because every email list cleaner charges per email, buy credits, pay per verification, watch your free trial expire. For small teams and agencies cleaning lists regularly, that cost adds up fast.

MailCull is free forever. Upload a CSV, we check for dead domains, disposable addresses, typos, and syntax errors, then you export a clean list. No credits, no credit card, no trial.
