Spec score 7.4 #23 of 33 in Temporary Email Services

What it is

MinuteMail is a developer testing platform for email and authentication flows, available on the web and through an API. It provides isolated test inboxes with lifetimes from 1 to 60 minutes; the default is 15 minutes when no duration is specified. Real-time SSE delivery and message lifecycle tracking help follow email flows, while a mock OAuth identity provider supports OAuth 2.0 authorization code flows with optional PKCE. Access options include a REST API, official Python SDK, and MCP server; setup guidance covers Claude Code, Claude Desktop, and Cursor. Accounts can use verified custom domains within plan limits, and API keys can be restricted by operation scope and allowed mailbox domains. MinuteMail says it uses HTTPS/TLS in transit, database encryption at rest, hashed API keys, and row-level security. Temporary mailboxes and messages are permanently deleted at expiry; archived mailboxes retain only the email address. The service advises using it for temporary, non-sensitive communications. A free plan has 50 API calls per day, two active mailboxes, and four archived mailboxes. Paid plans start at $86/yr.
