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
