In their own words
1SecMail
1SecMail provides temporary disposable email for sign-ups, with mailbox creation that does not require registration or personal information. Users can send and receive messages, create custom aliases, and receive attachments to download before they expire. Its guide says addresses and related communications are usually erased automatically after 24 hours. The service is available on web and Android, and a Chrome extension provides access to temporary email. Developers can use published API documentation covering domains, mailbox creation and management, message retrieval, and attachment downloads; however, the API-key feature is currently under development. Premium offerings list additional domains, inbox records, saved messages, attachment viewing, and support. The Premium page also advertises 100MB storage and no ads. A free plan is available; Standard costs $4.99 a month, and paid plans start at $4.99 a month. 1SecMail cautions that public temporary addresses are not suitable for sensitive or financial information.
EmptyInbox
EmptyInbox provides disposable email inboxes for AI agents and developers through a REST API, an MCP server and a web inbox. A new address can be created for each task or agent run. Messages can be polled, or received through the MCP wait_for_message flow, which can extract verification codes. The web inbox uses passkey sign-in and displays extracted codes and links alongside messages. Each inbox creation uses one credit; receiving, listing and reading messages are free. Messages are deleted automatically after seven days. EmptyInbox receives email only and has no sending endpoint or SMTP credentials. Listed integrations include MCP-compatible agents, OpenAI GPT Actions, LangChain, CrewAI and OpenAPI-compatible frameworks; workflow guides cover Playwright, Cypress, n8n and LangChain. The free plan includes five inbox credits and REST API and MCP access. One-time top-ups start at 1.00 USD for 10 credits, payable by Bitcoin or USDT. The project is open source under the MIT license, and questions go through GitHub issues.
