Hey everyone! 👋 spFlat! started as a personal itch I couldn't stop scratching. Running email for multiple domains, I kept hitting the same silent killer: SPF records with too many `include:` mechanisms quietly pushing past the RFC 7208 10-DNS-lookup limit — resulting in PermErrors and mail landing in spam. And the frustrating part? You often only find out after deliverability has tanked. I looked at the existing tools and found great DMARC reporting suites - but nothing that simply and affordably *keeps your SPF record valid* automatically. Flattening an SPF record by hand is a one-time fix that silently breaks the next time a provider changes their IP ranges. That's not a fix, that's a ticking time bomb. So I built spFlat!: 🔍 Free SPF lookup & PermError audit: paste your domain, see your lookup count instantly ⚙️ Automated flattening - includes resolved to direct IPs, 1 DNS lookup total 🔄 24/7 monitoring - provider IP range changes are picked up and the record stays valid, hands-off 🏢 MSP-friendly - built to manage SPF for many client domains The site just got a fresh redesign too, check out the before/after flattening demo on the homepage. I'd love your feedback: does the free lookup tool give you what you need? What would make you trust an automated DNS tool? AMA — I'm here all day. 🙏
