Import subscribers from Mailchimp and verify them

Connect your Mailchimp account, choose an audience, pull subscribers into mails.expert, and start bulk email verification without exporting CSV files by hand.

Spreadsheet imports

Upload CSV or XLSX files, map your columns, and send the list into the same verification flow used by the app.

File uploads

Paste or upload TXT and simple contact files when you just need a quick batch check without wiring any integration.

Mailchimp audience sync

Connect Mailchimp in your account, choose an audience, and import subscribers directly into a bulk verification job.

How integrations work

One account area for every import source

Connect the source in your account

Integration credentials live in your account settings, so public pages stay simple while the actual connection remains private.

Choose what to import

Pick the audience, file, or contact segment you want to verify. Each source feeds the same verification pipeline.

Review results in the same workflow

Imported emails land in bulk verification, where you can monitor progress, filter statuses, and export the clean list.
