Quickly Verify Your CNAME, SPF, DKIM, and DMARC Records

To ensure your email authentication records are correctly configured, follow these steps to check your CNAME, SPF, DKIM, and DMARC DNS records.

Note: Replace customer.com with your actual domain name.

Recommended Tool

You can use the Google Admin Toolbox Dig for a quick, browser-based way to check DNS records.
Alternatively, Mac and Linux users can use the dig command directly in the terminal.

1. CNAME Record

Command:

dig smart.customer.com

Expected Result:

whs.sendergen.com

2. SPF Record

Command:

dig txt customer.com

Expected to include:

include:_spf.sendergen.com

3. DKIM Record (Optional)

Command:

dig txt sg._domainkey.customer.com

Expected Result:
Your domain's DKIM record (generated from your email service provider) should appear.

4. DMARC Record (Optional)

Command:

dig txt _dmarc.customer.com

Expected Result:

v=DMARC1; p=none; rua=mailto:dmarc-reports@customer.com
