Important Notes

• When adding domain records in Resend, if your DNS provider is hosting your 3rd level domain a.b.com, please remove the 2nd level domain prefix b from the default name generated by Resend, otherwise it will add a.b.b.com, causing verification to fail. After adding the record, you can verify it using:

nslookup -qt="mx" a.b.com 1.1.1.1
