Set up email on a Squarespace Domains domain
Squarespace has its own DNS-record walkthrough, and we link to it for the registrar-side clicks. What this guide adds: the exact values to paste, a note for former Google Domains customers (your domain moved here in 2023), and how to confirm it worked in MailSprout.

Sign in and open DNS Settings
Go to account.squarespace.com (opens in a new tab), sign in, and open the Domains section.
Click the domain you're setting up. In the left sidebar, click DNS Settings. Scroll down to the Custom Records section. That's where you'll add and remove records.
Delete existing email records
Look through Custom Records and any “Preset Records” section above it. Delete:
- Any
MXrecords - Any
TXTstarting withv=spf1 - Any
CNAMEnamedautoconfigorautodiscover - Any
TXTnamed_dmarc
Common pre-existing values to remove: Google Workspace MX records (pointing at aspmx.l.google.com etc.), Squarespace email forwarding records.
Add the MailSprout DNS records
In the Custom Records section, click Add Record and select the type for each row below. For Host, use @ for apex (Squarespace also accepts blank).
| Type | Host / Name | Value | TTL |
|---|---|---|---|
| MX | @ | fusion.mxrouting.net (priority 10) | 3600 |
| Squarespace has a separate Priority field. Set to 10. | |||
| MX | @ | fusion-relay.mxrouting.net (priority 20) | 3600 |
| A second MX as the backup. Priority 20 means Squarespace only uses this if the priority 10 host is unreachable. | |||
| TXT | @ | v=spf1 include:mxroute.com -all | 3600 |
| TXT | (copy from dashboard) | (copy from dashboard) | 3600 |
| Both the host and the value for this record are unique to your domain. Open your MailSprout dashboard and copy them exactly as shown. | |||
| TXT | _dmarc | v=DMARC1; p=quarantine; rua=mailto:postmaster@yourdomain.com | 3600 |
Leave TTL at the default (typically 3600 / 1 hour) on every row.
Verify in MailSprout
Squarespace DNS is sometimes slower than other providers; wait up to 10 minutes if it doesn't verify on the first try. Go to your MailSprout dashboard, click the domain, press Verify DNS.
Add your first email account
Click Add account, type a name (e.g. hello), and scan the generated QR with your iPhone.
Troubleshooting
I see “Squarespace Email Campaigns” or “Acuity” warnings.
Google Workspace MX is still receiving mail even though I deleted it.
Verification is still failing 30 minutes later.
