SPF Checker

From "Spam Folder" to "Trusted Sender"

A healthy SPF record is the foundation of email success. Fixing it is the first step to unlocking your email's true potential.

🛡️ Protect Your Sender Reputation: Block attackers from impersonating your domain and maintain a good sender reputation with all major inbox providers.

📈 Maximize Your Deliverability: Land in the inbox, not the spam folder. A valid SPF is essential for passing DMARC and securing your place as a trusted sender.

A Single SPF Error Can Break Your Email Delivery

A hidden error in your SPF record is more than a technical problem, it's a business vulnerability.

Hidden Deliverability Issues

Blacklist or DNS errors can quietly damage your deliverability and lower open rates. These issues hurt your reputation.

Hidden Deliverability Issues

Your Emails Land in Spam

Mail servers (like Gmail, Outlook, and Yahoo) treat a broken SPF record as a high-risk signal.

Your Emails Land in Spam

You Hit a 'PermError' Wall

The most common and cryptic error is exceeding the 10 DNS lookup limit. This invalidates your entire record.

DMARC Checker

DKIM is your email's "digital signature." It proves that the email came from your domain and that its content hasn't been tampered with in transit.

Enforcement Policy: Checks your policy tag (p=) to see if you are at none (monitoring), quarantine (spam), or reject (block).

Reporting: Validates your rua= and ruf= tags to ensure you are set up to receive vital security reports.

Alignment: Confirms your SPF/DKIM alignment (adkim=, aspf=) is set to "strict" or "relaxed."
