How do I set up DMARC on a Squarespace domain?

What does Squarespace say?

Where the record goes depends on how your domain is connected.

Tip: If your third-party domain is connected via DNS Connect, edit your DNS settings in your third-party domain provider account instead of following this guide.

If your domain provider is Squarespace, the DKIM key is automatically created and added to your domain's DNS records.

What record do I publish?

Use your own domain and a mailbox you read for the reports.

1. Start herep=nonereports only
2. p=quarantinesuspicious mail to spam
3. Where to aimp=rejectforged mail refused

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

v=DMARC1; p=quarantine; rua=mailto:[email protected]

v=DMARC1; p=reject; rua=mailto:[email protected]

How do I add it at Squarespace?

3. Click Add record and sign in again if asked.Choose TXT in the Type menu.

In our words, from Squarespace's help page on adding TXT records, read 14 October 2026. If a screen has changed since, follow the host's own page.

Where is the change made?

Your DNS settings at Squarespace, in the list of DNS records for your domain. Nothing is changed in your mailboxes. If the domain is only connected, at the company that holds it.
