In their own words
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.
Mohmal
Mohmal provides temporary email addresses for receiving messages without exposing a personal inbox. Its web service is intended for tasks such as test registrations, OTPs, file downloads and reducing spam. The free anonymous service does not require registration, and inbox controls let users refresh, delete, inspect history, change an address or open the inbox through a QR code on a compatible device. Attachments can be viewed, but mailboxes cannot send email. Temporary message content is removed within a short period and is not retained longer than needed to provide the service. The privacy policy says the service needs no personal information, though it may collect browser and device details, viewed sites, IP address, general location and cookie data for analytics, advertising and functionality. Addresses are public and automatically generated, so another person with the same address may access messages. Mohmal cautions against using temporary email for sensitive, personal or confidential information. The free plan is available; paid plans start at $4.99/mo. Monthly or yearly Pro users can configure a personal domain for temporary addresses.
