EmptyInbox vs Getnada

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.

Getnada provides disposable email addresses with browser inboxes for signups, verification codes, trials and testing. Inboxes receive incoming messages only; they cannot send outbound email. Messages in public inboxes may be readable by anyone with the inbox URL, and temporary inboxes and messages are short-lived, with retention depending on operational policy. Its API supports creating and opening inboxes, listing and reading messages, polling and server-sent event streams when Redis is available. The maker describes API uses such as signup-flow and verification testing, inbox monitoring and automation, with cURL, PHP and Node.js examples. The free Guest plan provides guest-tier domains and up to three distinct @getnada.com addresses per browser or IP, but no API keys. The free Member plan requires email verification and allows up to two API keys, 40 active private inboxes and 10,000 API requests per day. Premium requires a manual upgrade; higher limits are negotiated through support. Getnada advises against using disposable inboxes for confidential or sensitive information.
