What this SPF record generator does

This SPF record generator helps you create a standards-friendly SPF TXT value from structured form fields. Instead of manually writing mechanisms, you can select providers, add IP ranges, and choose your policy, then copy a ready-to-publish record.

Why SPF matters for deliverability

SPF tells receiving servers which systems are authorized to send mail for your domain. A correct SPF setup reduces spoofing risk and supports stronger inbox placement when combined with DKIM and DMARC.

Publishing tips

Keep only one SPF TXT record per domain, avoid unnecessary include chains, and validate after DNS propagation. If you send from multiple platforms, document every sender source before enforcing -all.
