Free SPF Checker & Lookup
Instantly check if your domain’s SPF record is set up correctly and safe for email sending.
Why SPF Matters for Your Emails
SPF tells inbox providers which servers are allowed to send emails from your domain. If it’s missing or broken, your emails are more likely to:
- Land in spam
- Get rejected
- Damage your sender reputation
What This Tool Checks
Our SPF checker instantly analyzes your domain and shows:
- Whether an SPF record exists
- If multiple SPF records are detected (invalid setup)
- Which servers and services are authorized
- Your current SPF policy (~all, -all, etc.)
- Potential risks affecting deliverability
