Spamgourmet vs TempMaily

Spamgourmet is a free disposable-email service available on the web, with released code for self-hosting. It creates an alias automatically when the first message arrives, then forwards only a chosen number of messages to a protected address before discarding later mail. An address can allow up to 20 messages; the default is three when no number is supplied. Advanced mode provides trusted-sender controls, watchwords, prefixes, reply-address masking, and tools to view or edit addresses. Reply masking routes replies through Spamgourmet and keeps the protected return address hidden. The service filters only messages sent to disposable addresses, not mail sent directly to the protected address. Its privacy policy says messages are forwarded immediately or erased from volatile memory and that the code does not store email. Standard web and mail logs record IP addresses and may be reviewed for support or fraud investigations. The service is described as volunteer-run and non-commercial, with optional donations. Its Free plan costs nothing.

TempMaily provides disposable email inboxes for receiving verification codes and signup mail through web and API access. Its free inbox is created without signup, a password, or personal details, and messages appear in the browser as they arrive. Mailboxes are receive-only, so they cannot send email, although incoming messages can include attachments. The free plan permits one shared-domain address at a time; the inbox and its messages are permanently deleted 24 hours after creation, with transient storage and ads. Premium supports up to 10 addresses, custom and dedicated domains, long-term or permanent addresses, and 2GB of email storage. It also adds a REST API and MCP server for programmatic inbox creation and message reading. The MCP server works with Claude Desktop, Claude Code, Cursor, and MCP-capable agent frameworks. Premium costs $7.50 a year when billed annually ($90/year), or $9.90 a month. HTTPS, HTML sanitization, sandboxed rendering, disabled scripts, and blocked remote images are listed protections.
