Background

AutoSPF focuses exclusively on solving the "too many DNS lookups" issue in SPF records by automatically flattening and compressing all includes and nested DNS lookups into a single, optimized SPF record. It provides real-time updates, requires minimal configuration via a Copy-Paste-Replace setup, and is backed by Cloudflare DNS for high availability. It offers a "60-second setup" guarantee or a free year. Its mission is to enhance email deliverability, enable DMARC compliance, and simplify SPF management for enterprises and SMBs.

Copy, Paste, Replace Setup

Continuous Automatic Scanning

SPF includes are flattened in near real-time with rescanning every ~15 minutes, maintaining a dynamically optimized SPF record.
