Key facts

​
What it’s for

  • Receiving OTP codes, magic links, and verification emails
  • Signing up for trials and gated content without using your real address
  • Developer and QA testing of email-dependent signup flows
  • CI pipeline automation of email verification steps

​
What it’s NOT for

Do not use temporary email for accounts where long-term access matters: banking, healthcare, legal accounts, primary social media, or any service requiring email-based account recovery.
TempInbox is also receive-only — it accepts inbound SMTP mail but does not support sending outbound email.
