1) Get a disposable address
-
Visit m2u.io; an inbox is generated automatically or via a one‑click button.
-
Copy the address and use it where email verification is required.
2) Switch domains (optional)
-
If a target site blocks the current domain, choose another available domain.
-
Education‑related domain: for certain edu scenarios. Use lawfully and do not impersonate institutions.
3) Check the inbox
-
Return to m2u.io and view incoming messages. Some emails may arrive with a delay; refresh after a short wait.
-
If search/filter is available, use subject or sender to locate messages quickly.
4) Open messages and copy codes
-
Click a message to view its content and copy OTPs/links.
-
Be cautious with attachments and external links.
5) Cleanup and expiry
-
Messages expire automatically after a short period (typically no more than 48 hours; see site notices for specifics).
-
If a “clear/delete” function exists, you can manually purge the inbox.
Tips
-
Privacy & safety: disposable inboxes can be accessed by anyone who knows the address—avoid sensitive or long‑term content.
-
Delivery issues: try switching domains, check for filters, or ask the sender to resend.
-
Rate limits: to keep the service stable, we may throttle usage; wait and retry if you hit limits.
-
Do not use for critical matters: e.g., account recovery, finance/healthcare/government, contracts.
