100% free. Forever.
No subscription, no hidden costs, no "Pro" paywalls. Mail4Free.net doesn't finance itself through your data.
No tracking
No analytics cookies, no ad networks, no third-party data sharing.
Minimal data retention
Temporary inboxes are held in memory only and are deleted automatically and irreversibly. Only with an account are the mails of permanent aliases stored in the database.
How we fund this
Through donations and hosting/sponsorship partnerships instead of selling your data.
Enjoying Mail4Free.net?
Running this costs servers & time. A donation helps keep it free and ad-light - completely optional.
We only store what's needed to run the service: for an account, just your email address and a password hash.
The next level of your anonymity
100% free - sorted into two groups, depending on whether an account is needed.
🔓 No sign-up needed
Usable right away, no account required - just get started.
Spam score display
Every incoming mail automatically gets a risk score – no account needed.
QR code for your address
Show your address as a QR code - handy for picking it up quickly on another device or in a form.
Tracking pixel blocker
External images in mails are blocked by default – tracking pixels can't reveal whether you opened the mail.
Save as PDF
Save important messages as a PDF with one click — right from the message view.
Real-time inbox
New mail appears instantly via Server-Sent Events – no need to click "refresh".
Temporary mail in RAM only
All temporary mail is held exclusively in memory and expires automatically. Only with a free account are the mails of permanent aliases stored in the database.
🔑 With a free account
For permanent aliases and a bit more convenience - registration stays entirely optional.
Alias Vault
Organize all your aliases with tags and notes per website – never forget what an alias was for again.
Time-limited forwarding
Automatically forward incoming mail to your real address – choose 1, 7 or 30 days, or unlimited.
Telegram & Discord forwarding
Get notified in your chat when new mail arrives - subject & sender only, no content.
"Burn after reading"
Configurable per permanent alias: the mail is permanently deleted right after you open it the first time.
Share inbox as a read-only link
Generate a time-limited link that lets someone else read your inbox - no account needed on their end.
Export all mails as ZIP
Download your entire inbox as a ZIP file (one .eml per mail) with one click - e.g. before an address expires.
