Hey everyone! I built DMARCKit because I kept getting emails from friends asking "why are my business emails going to spam?" The answer was almost always missing or misconfigured DMARC/SPF/DKIM records.
The free scanner checks everything and gives you exact DNS records to copy-paste. The paid tier ($12/mo) monitors your domain daily and alerts you instantly if anything breaks... because DNS changes, DKIM keys expire, and email providers update their requirements.
Built solo on Cloudflare Workers + D1 + Next.js. The scanner is completely free with no signup required. Happy to answer any questions about email authentication or the architecture.
