Add SPF, DKIM and DMARC records in Namecheap

In Namecheap open Domain List, click Manage next to the domain, then the Advanced DNS tab, and click Add New Record. SPF, DKIM and DMARC are all TXT Records: Host @ for SPF, <selector>._domainkey for DKIM and _dmarc for DMARC. Leave your domain out of the Host field; Namecheap adds it.

What goes in Name

SPF · Name: @
DKIM · Name: <selector>._domainkey
DMARC · Name: _dmarc

Check the records after you save them

Enter the domain: SPF, DKIM at common selectors, DMARC and MX are looked up live, so you see whether Namecheap is serving the new records yet.

Lookups go from your browser to Cloudflare's public DNS resolver. If no selector is given, the checker tries the common ones.

Questions

How do I add a DKIM record in Namecheap?

Domain List > Manage > Advanced DNS > Add New Record. Choose TXT Record (or CNAME Record if your provider gives a CNAME), enter <selector>._domainkey as the Host without your domain, paste the value and click Save all changes.

What do I put in Host for SPF in Namecheap?

@, which means the domain itself. Keep one SPF record and put every sending service's include in it.

Why does my Namecheap record show the domain twice?

The Host field had the full name, such as _dmarc.example.com. Namecheap adds the domain, so the Host should be _dmarc alone.

How long do Namecheap DNS records take?

Namecheap says new host records normally take effect in about 30 minutes. Run the check above after that.
