How to Set Up SPF, DKIM, and DMARC on NameSilo
Prerequisites:
- Ensure you are using NameSilo's default nameservers:
- ns3.dnsowl.com
Or premium equivalents:
- If you’re using third-party nameservers, the records must be added at your DNS provider instead.
Set Up SPF (Sender Policy Framework)
What is SPF?
SPF prevents your emails from being marked as spam by verifying that mail servers sending on behalf of your domain are authorized.
Example SPF Records:
v=spf1 include:spf.titan.email ~all
How to Add on NameSilo:
- Value: Your chosen SPF string (e.g., v=spf1 include:spf.titan.email ~all)
Save and allow 48 hours for propagation.
Set Up DKIM (DomainKeys Identified Mail)
What is DKIM?
DKIM adds a digital signature to your emails, verifying that the message wasn't altered and is truly from your domain.
Steps:
- Click on the blue Manage Account button
- Next, Click on the Email Reputation Option
- Select the Add drop-down option to view the DKIM Record
- Add the TXT Record to NameSilo:
- Value: DKIM TXT value (starts with v=DKIM1; k=rsa; ...)
- Save and allow 48 hours to take effect.
- Return to Titan Manager and click:
- “I've added TXT records in my DNS control panel”
- Then click “Verify Changes”.
Set Up DMARC (Domain-based Message Authentication, Reporting & Conformance)
What is DMARC?
DMARC tells mail servers how to handle messages that fail SPF or DKIM checks and sends reports to help identify spoofing.
Example DMARC Record:
- p= options: none (monitor only), quarantine, reject
- rua=: Reporting email address
- pct=: Percentage of mail the policy applies to (start with 10–50%)
How to Add on NameSilo:
- Value: Your DMARC string (see example above)
- Save and allow 48 hours for propagation.
Best Practices:
- Start with: p=none to monitor without affecting delivery.
- Gradually move to: p=quarantine or p=reject as SPF and DKIM are confirmed working.
- Use a dedicated inbox for DMARC reports to manage volume.
Update your SPF/DKIM records if you add third-party senders (e.g., CRMs or marketing tools).
