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.
8 situations where a disposable email saves the day
- Sign up on an unknown site — receive the confirmation link without risking your real address.
- Download free resources — guides, ebooks, templates: get access without the automatic newsletters.
- SaaS free trial — test without being followed up commercially forever.
- Secondary social media account — Instagram, Reddit, Discord without exposing your identity.
- One-time online purchases — avoid unwanted post-purchase emails from unreliable shops.
- Forms and contests — participate without feeding marketing databases.
- Development testing — verify your sign-up flows, transactional emails and webhooks.
- Enhanced privacy — no IP address, no tracking cookies, full GDPR compliance.
mail123.click: what sets it apart
Most disposable email services force a random address impossible to remember. mail123.click lets you choose your own alias: come back hours later and simply re-enter the same identifier. With 12 distinct domains, if one gets blocked, switch in one click — your inbox stays the same. The inbox automatically detects OTP codes, extracts action links and supports push notifications for a frictionless experience.

Built-in Advanced Features
Attachments up to 5 MB — mail123box.tech receives and displays attached files: images, PDFs, archives, documents. Each attachment is downloadable directly from the inbox. Potentially dangerous files (.exe, .bat, .scr) are automatically blocked for your security.
Automatic OTP code detection — when an email contains a one-time verification code (2FA, registration confirmation), mail123box.tech identifies it and highlights it. Copy it in one click, no need to search through the message body.
Action link extraction — "Confirm", "Activate", "Validate" buttons are extracted and displayed at the top of the email. No more hunting for a link inside a complex HTML email.
Push notifications — enable browser alerts from the mailbox. You'll be notified the moment an email arrives, even with the tab in the background. Available on desktop and mobile.
Embeddable widget — developers and webmasters can embed an address generator directly on their site via a simple <iframe> tag. Learn more →
Security, privacy and GDPR compliance
No IP address is associated with created inboxes. No advertising cookie or third-party pixel is set without your consent. HTML emails are rendered in a sandboxed iframe that blocks scripts and external resources. Executable attachments (.exe, .bat, .sh, .js) are automatically filtered. The service follows GDPR privacy by design principles: minimal data collection, limited retention period, automatic deletion.
