A disposable email, also called temp mail, temporary email address or throwaway email, is a fully functional inbox created in seconds, with no account, no password and no personal information required. On mail123.click, your address is ready to receive messages instantly; data is automatically deleted after 7 days.
Why is your main email address at risk?
Every time you sign up online, your email is exposed to three real threats: spam (averaging 160 unwanted messages per inbox per day in Europe), targeted phishing (hackers buy databases of real email addresses), and data breaches (over 3 billion accounts compromised in 2023). A free temporary email address acts as a digital shield: it intercepts these risks before they reach your real inbox.
How to create a temporary email on mail123.click?
The process takes three steps:
- Choose a username from 3 to 32 characters (letters, numbers, hyphens), or let the generator create one randomly.
- Select a domain from the 12 available, all interconnected, the same username works on each.
- Access your inbox immediately, no confirmation, no SMS code, no waiting.
Emails arrive in real time; the inbox refreshes automatically every 30 seconds. After 7 days, everything is permanently deleted server-side. No email is ever forwarded to a third party or exploited commercially.
