Email verification for Mailchimp

Why verify in Mailchimp

Audiences fill up with typos, old mailboxes and imported lists. Clean the audience once and every send bounces less.

A Mailcut account and a CSV export from Mailchimp. New accounts get free credits, so you can test a sample first, and paid credits are bought once with no subscription.

How every integration works

1. In Mailchimp open Audience, then All contacts, and choose Export Audience. Download the CSV when the export is ready.
2. Upload the CSV to the bulk verifier and pick the email column.
3. Download the results: valid, invalid and risky files.
4. Back in Mailchimp choose Add contacts, then Import contacts, and upload the invalid file with the status Unsubscribed and the option to update existing contacts.
5. Import the risky file the same way with a tag such as risky, and send to that tag in small batches first.

A tip: Keep the original export. You can compare it with the verified file if something looks wrong.

What the results mean

• Valid: The mailbox exists. Send.
• Invalid: The address cannot receive mail. Remove it.
• Risky: Accepts mail but cannot be confirmed, for example a catch-all domain. Send in small batches and watch bounces.
• Unknown: The server did not answer. Retry later.
