An alias is an address that forwards to your own. Give each website a different one, and a site never learns your real address, a leak tells you which site leaked it, and an alias that gets spam is turned off.
Aliases are in the web vault, the desktop app and the browser extension.
Make one
- In the web vault or the desktop app, open Email aliases and choose New alias. Add a note of what it’s for, such as the website.
- In the browser extension, open This site and choose New email alias for this site. Vautir makes one for the page you’re on and copies it, ready to paste into the sign-up form.
Vautir picks the address: three random words and two digits, easy to read out and not to guess.
Receiving and replying
Mail sent to an alias arrives in your own inbox. The sender’s name shows who wrote, and which alias they wrote to.
Reply as you would to any email. Your answer leaves from the alias, with your own address taken out. You can reply through an alias, but not write to someone new from it.
Turn one off, or delete it
Turn off refuses an alias’s mail, and counts what was refused. Turn on lets it through again. Deleting an alias removes it for good.
How many
Free keeps five aliases at once. Premium and Families have as many as you like.
What we can see
The alias, that it’s yours, whether it’s on, and how many emails it forwarded and refused. The note of what it’s for is encrypted with your keys, so we can’t read it.
Email itself isn’t end-to-end encrypted: our relay reads each message as it passes, as any mail server does, and keeps none of them.
