How to Set Up DMARC for Mailchimp

Publish a DMARC record to protect your domain when sending marketing email through Mailchimp.

Quick Answer — The Record You Need

Record Type

TXT

Host / Name

_dmarc

Value

v=DMARC1; p=none; rua=mailto:[email protected]; ruf=mailto:[email protected]; fo=1

Complete Mailchimp domain authentication (SPF + DKIM) before enforcing DMARC.

Step-by-Step Setup

Complete Mailchimp domain authentication

Ensure both SPF and DKIM are configured and verified in Mailchimp before setting up DMARC.

Send a test campaign

Send a test email through Mailchimp and inspect the headers to confirm SPF and DKIM pass with your domain.

Create the DMARC record

Add a TXT record at _dmarc.yourdomain.com.

v=DMARC1; p=none; rua=mailto:[email protected]; ruf=mailto:[email protected]; fo=1

Monitor reports

Analyze DMARC aggregate reports for 2-4 weeks. Verify Mailchimp emails show aligned passes.

Enforce the policy

Gradually move from p=none to p=quarantine and then p=reject once all legitimate senders pass.

Common Gotchas

Mailchimp domain authentication must be complete for DMARC alignment. Without it, Mailchimp sends with its own domain in the envelope sender.
If you use Mailchimp alongside other email services, all services must be authenticated before enforcing p=reject.
Free Mailchimp accounts may have limited domain authentication options. Custom domain authentication is available on paid plans.

Frequently Asked Questions

Does Mailchimp support DMARC alignment?

Yes, when you complete Mailchimp domain authentication. This ensures the DKIM d= domain and SPF envelope sender align with your From domain.

Will DMARC enforcement block my Mailchimp emails?

Only if domain authentication is not complete. With proper SPF and DKIM configured through Mailchimp, your emails will pass DMARC and be delivered normally.

Do I need a separate DMARC record for Mailchimp?

No. DMARC is a single record per domain that applies to all email sent from that domain, regardless of provider. One DMARC record covers all your sending services.
