Porkbun
Publish your eusend DNS records at Porkbun — the Host field, the Answer field, and the 600-second TTL floor.
Porkbun's DNS editor is one of the plainer ones. The only thing to remember is
that the target field is called Answer, and that the root domain is an empty
Host field rather than @.
Add the records
Open the DNS editor
Sign in and go to Domain Management. Find your domain and click its DNS button — or open Details and choose the edit icon next to DNS Records. Click Add Record.
DKIM — required
| Field | Value |
|---|---|
| Type | TXT - Text record |
| Host | eusend._domainkey |
| Answer | the full v=DKIM1; k=rsa; p=… value from the dashboard |
| TTL | 600 |
Click Add.
DMARC — recommended
| Field | Value |
|---|---|
| Type | TXT - Text record |
| Host | _dmarc |
| Answer | 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 - Text record |
| Host | send |
| Answer | v=spf1 include:_spf.eusend.dev ~all |
Then a second record. The Priority field only appears once you choose MX:
| Field | Value |
|---|---|
| Type | MX - Mail exchange |
| Host | send |
| Answer | feedback.eusend.dev |
| Priority | 10 |
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.
Porkbun specifics
Host takes the subdomain only. Porkbun's documentation: for the root domain
"you will leave this field blank" — not @ — and for a subdomain "this is where
you will enter that subdomain name". So eusend._domainkey, _dmarc, send,
with no .acme.com.
600 seconds is the floor. Porkbun's minimum and default TTL is 600 seconds. You cannot go lower, and there is no reason to.
Porkbun's own email records. If you use Porkbun's email forwarding or hosted
email, leave the MX records at the apex exactly as they are. The eusend MX record
sits on send, which has no mail of its own, so the two never interact.
The Notes field is yours. It is local metadata, never published. Writing
eusend DKIM in it makes the record list readable a year from now.

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.
OVHcloud
Publish your eusend DNS records in an OVHcloud DNS zone — the trailing dot that decides whether your MX record works, and the record types to avoid picking.
