What Throwaway is
Throwaway provides temporary email inboxes without requiring signup, with web and API access. Users can select a username and domain or generate a random inbox, then receive mail automatically. Available lifespans are 1 hour, 24 hours, 7 days, and 14 days; the inbox and messages are deleted after expiry. An optional password can lock an inbox. The public REST API requires no authentication and allows 300 requests per IP address during each rolling 7-day period. Checking inboxes has a separate cap of 300 distinct previously unchecked addresses per IP over that period. Throwaway also presents file and image sharing as part of a privacy toolkit for people and AI agents. File uploads can reach 5 GB, with resume support, metadata review, optional passwords, and automatic expiry; files up to 25 MiB are virus scanned. Mail, files, and images are live, VPN is early access, and SMS is coming soon.
