How to Set Up DMARC for HubSpot

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

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 HubSpot domain authentication (SPF + DKIM) before enforcing DMARC.

Step-by-Step Setup

Complete HubSpot email domain setup

Ensure SPF and DKIM are both configured and verified in HubSpot settings.

Test email authentication

Send a test email from HubSpot and verify SPF and DKIM pass in the email headers.

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

Review aggregate reports

Monitor DMARC reports for 2-4 weeks to confirm HubSpot emails pass alignment.

Move to enforcement

Gradually move from p=none to p=quarantine to p=reject.

Common Gotchas

HubSpot must have email domain authentication complete for DMARC alignment. Without it, emails are signed with HubSpot's domain.
If you use HubSpot alongside other email services (Google Workspace, SendGrid, etc.), all must be authenticated before enforcing.
HubSpot free and Starter plans may have limited email domain authentication features. Check your plan's capabilities.

Verify Your Setup

After adding your DNS records, use our free DMARC checker to verify everything is configured correctly. DNS changes typically propagate within minutes, but can take up to 48 hours.

Frequently Asked Questions

Does HubSpot support DMARC alignment?

Yes, when email domain authentication is complete. This aligns the DKIM d= domain with your From domain.

Will DMARC enforcement block my HubSpot marketing emails?

Only if email domain authentication is not complete. With SPF and DKIM properly configured, HubSpot emails pass DMARC.

Do I need DMARC for HubSpot if I already have it for Google Workspace?

DMARC is one record per domain. If you already have a DMARC record, it covers all email from your domain, including HubSpot. You do not need a separate one.
