Use a temporary email
For one-time verification, downloads, trials, and replaceable forum accounts. You do not need ongoing contact or email-based recovery after the task ends.
Inbox exposure check
Should you share your real email?
Check the signals that match your current situation. This is not a security certification, but a guide to choosing between a temporary address, a long-term alias, and your everyday email.
Check the signals that match your task
Assess the use case, then choose an address
Temporary email suits short-term, replaceable situations with high marketing risk; important identity accounts should use an email address you control long term.
Decide first, then share your address
Three cards to define yourexposure boundary
Use a long-term alias
When you need ongoing notifications but do not want to expose your primary email. Use one alias per source and revoke only that entry point if marketing gets out of control.
Use your everyday email
For banking, government, work, healthcare, and important paid accounts. You must control the address long term, with recovery options and two-step verification enabled.
Exposure is more than a breach
Repeatedly submitting the same email can create a linkable identity
Your everyday email connects sign-ups, marketing, and data incidents across different sites. A separate address cannot stop third parties from collecting activity on their own site, but it can reduce direct links between sources.
- Use a separate alias for public sources
- Let the address expire when a short task ends
- Keep reliable recovery methods for important accounts
