Throwaway review
A free temporary email service with flexible expiry, inbox passwords, REST, and MCP access.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Throwaway creates disposable email addresses and temporary inboxes without signup. It is aimed at users who need a short-lived inbox for temporary communications, testing account flows, or separating disposable messages from a primary address. Users can choose a username, select an available domain, and set an expiry of 1 hour, 24 hours, 7 days, or 14 days. The service automatically deletes the inbox and its messages when that period ends, while password locking adds control for users who want to protect access to an inbox.
Throwaway is free, with no paid tier described in its published plans. Its web interface covers direct inbox creation and reading, while the REST API supports automated inbox creation and message reading. The published service notes also advertise 137 domains and a 300-requests-per-7-days allowance per IP, making the API useful for limited automation rather than unrestricted, high-volume workflows. The expiry choices are clearly defined, so the product fits tasks where retention should be deliberately short.
Its strongest distinction is the combination of user-selected inbox details, password protection, automatic fetching, and AI-agent access. REST and MCP endpoints connect with Claude, OpenClaw, Hermes, and OpenAI, giving developers and agent workflows a direct path to temporary email operations. Throwaway is a good pick for free users who want more control than a randomly generated disposable address provides, especially when API or MCP access matters. It is less suitable for workflows that depend on verified attachments, retention beyond 14 days, or an API allowance above the stated limit.
