Instantly verify your domain’s SPF record configuration and strengthen your email security. Ensure your messages are authenticated, protected, and delivered successfully.
Cybercriminals will often use a trusted domain to send fake emails to trick users and customers. If a valid SPF record doesn't exist, your emails can be flagged as spam, or worse, be used for phishing.
That's why we created the SPF Record Checker - a free online tool that allows you to quickly analyze and verify your domain's SPF record in one simple scan. You'll learn if your SPF setup is properly validated for secure email delivery, and whether it is properly optimized.
The SPF Record Checker does a real-time lookup of the DNS records for your domain to find and confirm your SPF record. It evaluates each mechanism and modifier to indicate whether or not your SPF record correctly allows, denies, or fails email senders.
SPF (Sender Policy Framework) is one of the three foundations of email authentication, alongside DKIM and DMARC.
An SPF record that is properly configured will stop customers from sending mail on your behalf from untrusted servers.
If your domain ’s SPF record is not valid, the SPF record checker will offer actionable fixes and recommendations you can use.
It is a utility to check your domain’s SPF record to verify that only the authorized mail servers have the ability to send emails using your domain.
It uncovers configuration mistakes, invalid syntax and unidentified IPs, allowing you to keep your email communications safe and trusted.
No. Each domain should only have a single SPF record. Two records can lead to authentication problems.
Your domain will be open to spoofing and your emails could be marked as junk.
With any changes to the DNS or email services, use the SPF Record Checker to make sure your SPF record is still valid.
