Upload the raw `.eml` of an email you already sent, or paste the HTML, and Will It Spam tells you in plain English why it might land in spam. It runs 12 checks: SPF, DKIM and DMARC read from the real headers, RFC 8058 one-click unsubscribe, the seven CAN-SPAM requirements, and content signals like spam words and image-to-text ratio. Every failure names the exact fix — the header to add, the line to change. No signup, nothing stored, and it runs on Cloudflare Workers — free, and it stays free.
