What TempoMail is

TempoMail provides disposable email addresses for sign-ups, verification codes, and other situations where you do not want to share your regular address. You can choose an inbox name or generate one, then set its retention to 1 hour, 24 hours, 7 days, or 30 days. Messages are permanently deleted when the selected period ends. The service is receive-only: composing, sending, and replying are not available. Its free plan costs nothing and requires no registration. The read-only REST API allows 30 requests per minute, with up to 50 messages in a message-list response. The official extension for Chrome, Edge, Brave, and Firefox can create and autofill addresses on signup forms and open the inbox in a side panel. TempoMail says stored email is encrypted at rest with AES-256-GCM and connections use TLS, but this is not end-to-end encryption. Inbox access uses a six-character code that cannot be recovered if lost. Emails over 5 MB and messages from invalid senders are rejected. It works in a mobile browser, with no dedicated mobile app.
