Web-based email deliverability testing tool. Users send a message to a disposable address (accepts one message, expires after one hour) and receive a report with 42 checks covering SPF, DKIM, DMARC, ARC, TLS, reverse DNS, MX, blocklists, content analysis and Gmail/Yahoo bulk sender rules. Provides two scores: a classic SpamAssassin-style score (0-10, lower is better) and a proprietary 0-100 score. Also offers inbox placement tests showing which folder the message lands in at Gmail, Outlook, Yahoo and other providers, free DNS checkers (SPF, DMARC, DKIM, blocklist), an API, and an MCP server with four tools (get_test_address, wait_for_report, get_report, get_message_source). Built and maintained independently by Serhii Tanichev.
