Add Domain to Resend

First, login to your Resend Account and add a domain.

It is a 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).

Login to Route 53

Then, login to your AWS Management Console, and open Route 53 console, then click on your domain name. From there, click on Create Record.

Add MX SPF Record

Click the Record type dropdown, and select MX. Then, type in send for the Record name, and copy the record into the Value field. (be sure to include the 10, as seen in the screenshot!)

Omit your domain from the record values in Resend when you paste. Instead of send.example.com, paste only send (or send.subdomain if you’re using a subdomain).

Then, click on Create records.

Below is a mapping of the record fields from Resend to Route 53:

Route 53ResendExample Value
Record TypeTypeMX Record
Record nameNamesend
ValueValue & Priority10 feedback-smtp.us-east-1.amazonses.com
TTL-Use Route 53 Default (300)
Routing policy-Simple routing

Route 53 does not label the priority column, and you will need to add this in to the Value section, as shown in the screenshot. Do not use the same priority for multiple records. If Priority 10 is already in use, try a number slightly higher like 11 or 12.

Add TXT SPF Record

Once again, click the Record type dropdown. Then, select TXT. Then, type in send for the Record name, and copy the record into the Value field.

Below is a mapping of the record fields from Resend to Route 53:

Route 53ResendExample Value
Record typeTypeTXT Record
Record nameNamesend
ValueValue"v=spf1 include:amazonses.com ~all"
TTL-Use Route 53 Default (300)
Routing policy-Simple routing

Omit your domain from the record values in Resend when you paste. Instead of send.example.com, paste only send (or send.subdomain if you’re using a subdomain).

Add TXT DKIM Records

In the same section, click on Add another record.

This time, change the Record name to resend._domainkey, and change the Record Type to TXT. Add the TXT Record from your domain in Resend to the Value text box, then click on Create Records.

Below is a mapping of the record fields from Resend to Route 53:

Route 53ResendExample Value
Record typeTypeTXT Record
Record nameNameresend._domainkey
ValueValuep=MIGfMA0GCSqGSIbRL/a21QojogA+rYqIQXB/3DQEBDAQAB
TTL-Use Route 53 Default (300)
Routing policy-Simple routing

Omit your domain from the record values in Resend when you paste. Instead of resend._domainkey.example.com, paste only resend._domainkey (or resend._domainkey.subdomain if you’re using a subdomain).

Complete Verification

Now click Verify DNS Records on your Domain in Resend. It may take up to 5 hours to complete the verification process (often much faster).

Troubleshooting

If your domain is not successfully verified, these are some common troubleshooting methods.
