Pair it with our SMTP-grade verification to keep your sender reputation healthy, drive higher open rates, and protect your inbox placement.

Whether you import lists from Mailchimp for a one-off cleanup or pipe new sign-ups through emailcheckerr in real time, you get the same disposable / role / accept-all detection, deep MX validation, and quality scoring used by enterprise teams — at a fraction of the cost.

How it works

Export your audience

In Mailchimp, export your subscriber list (or a specific segment) as a CSV.

Run it through emailcheckerr

Upload to emailcheckerr — we'll flag invalid syntax, disposable addresses, role-based mailboxes, and catch-all domains. Most lists complete in under five minutes.

Re-import only deliverable contacts

Download the cleaned subset and re-upload to Mailchimp. Suppress the risky ones, or unsubscribe undeliverable addresses to keep your sender reputation clean.
