Smart SPF Auto Builder & Infrastructure Scanner

SPF Records Tools

Automatically construct the perfect SPF record. Our smart DNS crawler scans your live A and MX records, detects your email providers, and pre-configures a secure, RFC-compliant policy tailored to your exact infrastructure.

Smart SPF Auto Builder

Enter your domain name to let our backend crawler discover your current email infrastructure and auto-generate the perfect, RFC-compliant SPF record for you.

Why Use SPF Auto Builder?

Don't guess which mechanisms you need. Let our smart DNS crawler analyze your domain and automatically construct the perfect, secure Sender Policy Framework for you.

Smart Infrastructure Scan

The Auto Builder queries your live DNS to detect your existing A and MX records. It uses this real-time data to pre-configure your SPF mechanisms accurately.

Auto-Suggested Providers

If your MX records point to Google, Microsoft, Zoho, or ProtonMail, the builder instantly detects it and automatically recommends the correct `include` statement.

Interactive Visual Studio

No need to memorize complex syntax. Toggle core mechanisms, add specific IPv4/IPv6 addresses, and switch strictness policies using a clean, visual interface.

Existing Record Detection

If you already have an SPF record, the builder extracts it, parses its current mechanisms, and loads them into the interactive studio so you can safely edit and upgrade it.

Catch-All Policy Enforcement

Easily select how receiving servers should handle unauthorized emails. Choose between Soft Fail (~all) for safe deliverability or Hard Fail (-all) for strict spoofing prevention.

100% Private Processing

Your domain lookups and generated configurations are processed securely. Your data remains completely private and is never logged on our backend servers.
