Landed: find out why your cold email lands in spam, and get the exact fix. Founders who sell by cold email lose deals they never see. The sending tool says "sent", but the message went to spam or junk, and nobody tells you. Finding out why means reading raw headers, DNS records, blocklists and provider codes most founders have never seen. The fix is usually a few exact DNS records and one or two sending changes. Landed is an agent that does that investigation. Give it your sending domain, and if you have them, the headers of an email that went to spam or a bounce message. Muse Spark plans the investigation and calls live tools: SPF with its include chain and the 10-lookup limit, DMARC, DKIM selectors and key size, MX and the receiving provider, domain and IP blocklists, reverse DNS, domain age, and a header parser that reads SPF, DKIM, DMARC and compauth results, Microsoft's spam scores (SCL, BCL, SFV, CAT) and one-click unsubscribe. It follows leads, like checking the sending IP it found in the headers, and returns one case report: the most likely cause in a sentence, the evidence it read, and the fixes in order, with copy-paste DNS records. A Re-check button reruns only the failing checks so you can see the fix take. Why it holds up in production: - Live data: every check runs against real DNS over HTTPS, on any domain you type. No canned results. - Honest gaps: when a blocklist refuses a public resolver, Landed says "could not read" instead of "clean". - Never a blank page: if the model is down, a deterministic rules engine still returns the report, marked "rules-only". - Built to be used by other tools: a JSON API and a command-line tool, so a team can run it before every campaign launch. - Tested: 104 unit tests for every parser and the agent loop. Open source, MIT. Builder: Richman Chea founded Operator Pipeline and built and runs the outbound system that has booked 2,447 meetings for 14 financial advisors since October 2025 (booked, not held). In October 2026 he stood up a sending fleet of 40 mailboxes on 20 domains, all passing SPF, DKIM and DMARC. Landed is the tool he wished he had.
