Squarespace Domains
Publish your eusend DNS records at Squarespace Domains — formerly Google Domains. The Name field appends your domain, and the default TTL is four hours.
Squarespace took over Google Domains, so domains bought from Google are managed here now. The panel appends your domain to the Name field, and its default TTL is unusually long.
You can only edit DNS here if the domain is registered with Squarespace or connected through
Nameserver Connect. If it is pointed somewhere else, the records belong at that provider — check
with dig +short NS acme.com.
Add the records
Open DNS settings
Open the domains dashboard, click your domain, then DNS → DNS Settings. Scroll to Custom Records and click Add record. You will be asked for your password or a 2FA code before the record saves.
DKIM — required
| Field | Value |
|---|---|
| Type | TXT |
| Name | eusend._domainkey |
| Text | the full v=DKIM1; k=rsa; p=… value from the dashboard |
Click Save.
DMARC — recommended
| Field | Value |
|---|---|
| Type | TXT |
| Name | _dmarc |
| Text | v=DMARC1; p=none; rua=mailto:dmarc@acme.com |
Use an address you actually read for rua — see DMARC.
Return-Path — optional, both or neither
| Field | Value |
|---|---|
| Type | TXT |
| Name | send |
| Text | v=spf1 include:_spf.eusend.dev ~all |
Then a second record:
| Field | Value |
|---|---|
| Type | MX |
| Name | send |
| Priority | 10 |
| Mail Server | feedback.eusend.dev |
Publish both and eusend switches your mail to a bounce address on your own domain, so SPF passes and aligns. One without the other does nothing.
Squarespace specifics
The Name field appends your domain. Squarespace's documentation puts it
plainly: "Squarespace automatically adds your domain to the Name field. This means
if your provider asks you add your domain to the Name field, like yourdomain.com,
you'll enter @." So eusend._domainkey, _dmarc and send — never with
.acme.com on the end.
The default TTL is four hours. Every custom record gets 14400 seconds unless you change it. That is fine for records you are publishing once, but it means a correction takes up to four hours to be seen. If you expect to fix a typo, set a shorter TTL on the way in.
Email presets can overwrite things. Squarespace offers one-click presets for Google Workspace and other mail providers that write a batch of MX and TXT records. Applying one after you have added the eusend records can replace records at the same names — add the presets first, then the eusend records.

dig +short TXT eusend._domainkey.acme.comIf it is empty, check whether the domain was appended twice:
