Set Up a DMARC Record on Namecheap
A DMARC record is a TXT record at _dmarc.yourdomain.com that tells inbox providers what to do with mail that fails SPF or DKIM, and where to send reports. This guide shows exactly where to add it in Namecheap. For the background, read What Are SPF & DMARC?.
What you'll need
- A mailbox address to receive DMARC reports, for example
dmarc@yourdomain.com. - SPF and DKIM already set up for your sending domain. See SPF on Namecheap and DKIM on Namecheap. DMARC checks them, so it is only useful once they pass.
Step 1: Open your domain's DNS in Namecheap
- Go to namecheap.com and sign in.
- Click Domain List in the left-hand menu, find your domain, and click Manage.
- Open the Advanced DNS tab. The Host Records section lists every DNS record on the domain.
Step 2: Add the DMARC TXT record
- Click Add New Record and choose TXT Record as the type.
- In the Host field: Enter
_dmarconly. Namecheap adds your domain to the end automatically, so typing_dmarc.yourdomain.comwould create the wrong record. - In the Value field: Paste
v=DMARC1; p=none; rua=mailto:you@yourdomain.com, using your own report address. - Leave TTL on Automatic.
- Click the green checkmark to save the row, then Save All Changes.
| Field | What to enter |
|---|---|
| Type | TXT |
| Host | _dmarc |
| Value | v=DMARC1; p=none; rua=mailto:you@yourdomain.com |
Start with p=none, then tighten
p=none only watches and reports. It is the safe way to start because it cannot block any of your own mail. After a few weeks of clean reports, move to p=quarantine (send failures to spam) and later p=reject (block them). Jumping straight to p=reject risks blocking legitimate mail if an SPF include is missing.
If you already have a DMARC record
A domain can only have one DMARC record. If Namecheap already lists a TXT record at _dmarc, edit it instead of adding another.
Step 3: Check DMARC in Warmerly
Warmerly rechecks your domain's DNS automatically. DNS changes can take anywhere from a few minutes up to 24 to 48 hours to spread, so if the DMARC warning is still showing right after you save, check again later. You do not need a selector for DMARC, because it is one record at a fixed location.
