In their own words
TempMaily
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.
