Vercel
Verify your domain on Vercel with Resend.
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 Vercel
Login to your Vercel account and select the Domains tab.
Add MX SPF Record
Copy and paste the values in Resend to Vercel. Type send for the Name of the record in Vercel. Expand the Type dropdown and select MX. Copy the record value from Resend into the Value field in Vercel. Add 10 for the Priority.
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 Add.
Below is a mapping of the record fields from Resend to Vercel:
| Vercel | Resend | Example Value |
|---|---|---|
| Type | Type | MX Record |
| Name | Name | send |
| Value | Value | feedback-smtp.us-east-1.amazonses.com |
| TTL | - | Use Vercel default (60) |
| 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
In the same section, add another record in Vercel.
Once again, type send for the Name of the record. Expand the Type dropdown and select MX. Copy the record value from Resend into the Value field in Vercel. Add 10 for the Priority.
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).
