Email Authentication on Namecheap

Namecheap's Advanced DNS panel is where all email records live. Here's how to add SPF, DKIM, DMARC, and MX records correctly.

Everything lives under Domain List → Manage → Advanced DNS. Use the Host field: @ for root, subdomain only for DKIM, _dmarc for DMARC. TTL is usually Automatic — there's no orange cloud.

SPF record

One v=spf1 TXT at root — merge providers.

→

DKIM record

TXT at selector._domainkey — paste full key.

→

DMARC setup

TXT at _dmarc — start with p=none.

→

MX record

Priorities, hostnames, no proxy where applicable.

→

Expiry monitoring

Auto-renew and WHOIS cross-check.

→

Domain lock

Transfer lock — verify before you move.
