Add Domain to Resend
First, log in to your Resend Account and add a domain.
It is best practice to use a
subdomain
(updates.example.com) instead of the root domain (example.com). This allows
for proper reputation segmentation based on topics or purpose (e.g.
transactional and marketing).
Log in to Hetzner
Log in to your Hetzner account:- Choose your Domain from the
Your Zoneslist. - Select the
Recordstab to get to the page to manage DNS records.

Add MX SPF Record
In theCreate Record section on Hetzner copy and paste the values MX from Resend:
- On the
Typepage, chooseMX. - Type
sendfor theNameof the record. - Select the
Valuefield. - Use the default
Priorityof10. - Copy the MX Value from Resend into the
Mail serverfield. - Select the TTL of
1800. - Select
Add Record.
Hetzner requires your MX record to have a trailing period when adding. Resend
will include the trailing period when copying. Removing the period will cause
the verification to fail.


| Hetzner | Resend | Example Value |
|---|---|---|
| Type | Type | MX Record |
| Name | Name | send |
| Mail server | Value | feedback-smtp.us-east-1.amazonses.com. |
| TTL | - | 1800 |
| Priority | Priority | 10 |
Do not use the same priority for multiple records. If Priority
10 is already
in use on another record, try a number slightly higher like 11 or 12.Add TXT SPF Record

Typepage, chooseTXT. - Type
