Does Mailchimp have built-in email verification?

Mailchimp offers Omnivore, an abuse-detection system that flags some risky addresses during import. However, it does not perform full SMTP verification on your existing audience. Truelist checks every address individually.

How do I connect Mailchimp to Truelist?

Click "Connect Mailchimp" in your Truelist dashboard. You will authorize through Mailchimp OAuth and your audiences sync automatically.

Can Mailchimp suspend my account for bounces?

Yes. Mailchimp enforces strict bounce rate limits and will suspend or terminate accounts that exceed them. Verifying before sending is the best way to avoid this.

Will cleaning my list actually lower my Mailchimp bill?

Yes. Mailchimp bills based on total audience size. Removing invalid and inactive contacts can drop you to a lower pricing tier.

How often should I verify my Mailchimp list?

Verify before any major campaign and at least quarterly. Lists with high signup volume or older contacts decay faster.

How the Mailchimp integration works

Truelist connects to Mailchimp via OAuth 2.0. After authorization, Truelist reads your audiences and segments through the Mailchimp API, runs SMTP-level verification on each contact, and delivers results you can act on directly without manual CSV exports or imports.
