Resend domain stays pending because the DNS host rewrote resend._domainkey or the send MX

Domain stuck in pending or failed for hours

Verified 2026-10-15 · Confirmed by 0 builders · Trust 50/100

Cause

Many DNS dashboards append the zone name to the host and sometimes to the MX value, and Cloudflare proxying hides CNAME targets. The records Resend checks then never resolve as entered.

Fix

Enter only the prefix as the host (resend._domainkey, send), add a trailing period to the MX value, set Cloudflare records to DNS only, then use Restart verification.

Apply

nslookup -type=TXT resend._domainkey.example.com && nslookup -type=MX send.example.com && nslookup -type=TXT send.example.com

Affects: Resend domain verification with Cloudflare, GoDaddy, Namecheap and similar DNS hosts, as of 2026-10
