Disposable Inboxes

Frequently asked questions

  • Is PocketInbox free?
    Yes — 100% free, no signup, no credit card. PocketInbox is supported by display ads (only loaded after you accept the advertising category in our cookie banner).
  • Do disposable inboxes receive verification codes?
    Yes. Most signup, login and password-reset emails arrive within seconds. We auto-detect 4–8 digit OTP codes and surface them with a one-tap copy button.
  • How long does an inbox last?
    Between one hour and seven days, depending on the upstream provider. Mail.tm and Mail.gw retain inactive accounts for ~7 days; Guerrilla Mail expires after ~1 hour.
  • Can I send email from a temp address?
    No — by design. Disposable inboxes are receive-only. This keeps the service useful for anti-spam and prevents anonymous-spam abuse.
  • Is it safe to open emails here?
    PocketInbox sanitises every HTML body with DOMPurify and renders it inside a sandboxed iframe with no script execution. Cross-site script attempts in incoming mail can’t run.
