Using aliases and catch-all
Create aliases, use plus addressing, set up a catch-all, generate masked aliases and stop unwanted mail.
An alias is another address that delivers to the same inbox. In eoinbox they are cheap: make as many as your plan allows, and turn off any that start getting spam.
Create an alias
- In webmail: open Settings → Addresses → New address, pick the domain and type the name.
- While writing: type a new address on your domain into the From field. It is created when you send.
- From the API or a password manager: see Using the API.
Each alias can have a note, for example "signed up at example-shop", and shows how many messages it received and when the last one arrived.
Plus addressing
Every address also accepts a +tag: mail to you+shop@yourdomain.com reaches you@yourdomain.com. No setup needed. You can create a rule that files mail with a given tag into a folder.
Some websites reject the + character. Use a real alias for those.
Catch-all
With catch-all on, mail to any address on the domain reaches you, even addresses you never created. Turn it on in the domain's settings. While it is off, mail to unknown addresses is rejected with a clear error to the sender, never silently dropped.
When a message arrives through catch-all, eoinbox remembers that address and lists it with your other addresses. If it starts getting spam, block just that address and keep catch-all on for everything else.
Catch-all is included in the Standard and Plus plans.
Masked aliases
A masked alias is a random address such as bright.otter.17@yourdomain.com, made for one website. Create one in Settings → Addresses → New masked alias, from the API, or straight from the Bitwarden password generator (setup). If you do not pick a domain, masked aliases use our shared domain alias.eoinbox.com.
Pause or block an address
Every message has a Block this address button, and every address has a status:
| Status | Effect |
|---|---|
| Active | Mail is delivered |
| Paused | Mail is rejected and the sender gets an error |
| Blocked | Mail is accepted and quietly dropped, so the sender cannot tell |
Use Paused when you want the sender to know the address no longer works. Use Blocked for spam. You can switch an address back to active at any time.
Where mail goes
Per address, choose: the inbox, a specific folder, forwarding to another address, or both inbox and forwarding. External forwarding addresses must be confirmed by clicking a link we send them.
Replying from aliases
When you reply, eoinbox sends from the address the message was sent to. This keeps your main address private when you reply to mail that came through catch-all or a masked alias. You can always pick a different address in the From field.
Aliases on the Free plan
On the Free plan, aliases forward to the address you signed up with. Each forwarded message gets a reverse alias as its reply address, such as r.k3j9x2@reply.eoinbox.com. When you reply from your normal mail app, the reply goes through eoinbox and is sent from your alias, with traces of your real address removed. Reverse aliases only work for replies to the person who wrote to you, and there is a daily limit.
