Temporary email generates a disposable inbox address instantly — no sign-up required — for receiving registration verification emails, testing email systems, or keeping your real address off untrusted sites. The inbox auto-refreshes every 10 seconds, and you can view HTML or plain-text email bodies as well as download attachments.
Custom Address Name Rules
You can type a custom username before the domain, or leave it blank for a random one. Allowed characters are letters, numbers, dots (.), hyphens (-), and underscores (_). The name cannot start or end with a dot, and two consecutive dots like a..b are rejected. The UI shows the specific error when a name fails validation.
Different domains have different delivery rates depending on the site you're registering with. Some sites maintain a blocklist of known disposable email domains. If mail isn't arriving on one domain, switch to another and regenerate.
How Long the Address Lasts
Addresses and their mail are not kept permanently. The default validity window is about 1 hour — after that the address expires and received emails are cleared. Use or copy any verification links or codes immediately; do not rely on temporary mail for anything you'll need to access again later.
Your current session's inbox token is stored in browser localStorage. Closing and reopening the tool tab will attempt to restore the last address, but clearing browser data or switching devices makes recovery impossible.
When Mail Doesn't Arrive
- The target site blocks disposable email domains → switch to a different domain and retry
- Mail is still in transit — wait 30 seconds, then hit manual refresh
- The address has already expired → generate a new one and re-register
- The site's own validation rejected the address format → try a different custom name
