Hi Product Hunt! 👋 I'm the maker of DKIMCheck.
Email deliverability has become a massive headache recently, especially with Gmail and Yahoo's strict new sender requirements. I built DKIMCheck because existing tools were either incredibly slow, bloated with ads, or locked simple DNS checks behind expensive paywalls.
What makes DKIMCheck different? ⚡ Speed: Built entirely on Cloudflare Workers edge nodes. It runs encrypted DoH (DNS-over-HTTPS) queries in under 50ms. 🛠️ SPF Flattening: If you use Google Workspace + SendGrid + Hubspot, you've likely hit the RFC 7208 10-lookup limit (PermError). We automatically generate a flattened 0-lookup SPF record for you. 🏅 Verified Badges: Once your domain is healthy, you can embed a dynamic "100% Pass" badge on your site to build trust.
It's completely free to run the scanner. We also offer automated monitoring to alert you if a third-party service breaks your DNS records silently.
I'd love to hear your feedback, and I'm here all day to answer any questions about the tech stack (Cloudflare Hono + D1) or email deliverability in general! 🥂
