MinuteMail vs Temp-Mail.org

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.

Temp-Mail.org provides disposable email addresses so you can receive messages without using your regular inbox. Addresses are available without registration. You can copy an address, refresh its inbox, change it, or delete it; the service does not send email. The free plan includes receiving messages with attachments and downloading them as EML files, with messages stored for up to 1–2 hours. Premium extends storage to one month and includes up to 10 simultaneous mailboxes, premium domains, private addresses, and no ads. Premium monthly costs $10 a month, billed monthly and auto-renewing; yearly costs $60 a year, billed yearly and auto-renewing. Both plans are desktop web only. The service is also available on Android, iOS, as an extension, and through an API. Its API supports automated email workflow testing with Selenium, Cypress, Playwright, or Puppeteer. Some government services and major financial institutions cannot send messages to it, and certain role addresses cannot be read. Messages in the public system may be visible to other users, so the service advises against using it for confidential information or important accounts.
