An address for everything, all in one inbox
Addresses should be cheap. Make one per shop, newsletter or project in a couple of seconds, see where mail comes from, and switch off any address that starts getting spam.
Kinds of addresses
| Type | Example | How it behaves |
|---|---|---|
| Main address | ana@yourdomain.com | Your default sending identity. It does not have to match your login. |
| Alias | info@yourdomain.com | Delivered to the same mailbox. You can send from it. |
| Plus addressing | ana+shop@yourdomain.com | Always works, no setup. The +tag can file mail into a folder automatically. |
| Catch-all | anything@yourdomain.com | Catches addresses that do not exist yet. The first message "learns" the address, so you can block it later on its own. |
| Subdomain wildcard Later | x@shop.yourdomain.com | Like catch-all, but on a separate subdomain, so your main domain stays tidy. |
| Masked alias | bright.otter.17@yourdomain.com | Random, linked to the website you used it on. Created from the API, the Bitwarden generator or webmail. |
| Forwarding | mum@yourdomain.com → mum@example.net | Not a mailbox, just a redirect to another address, done in a way that keeps SPF and DMARC passing. |
Plan limits for aliases, masked aliases and catch-all are on the pricing page.
Replies come from the right address
When you reply, eoinbox picks the address the message was sent to. This matters most for catch-all and masked aliases: your main address never leaks to a shop or a stranger.
Pause or block in one click
Every message has a "Block this address" button. Paused addresses bounce with a clear error; blocked addresses are dropped quietly, if that is what you choose. Either way you can turn them back on.
Notes and statistics
Each alias can carry a note such as "signed up at example-shop", and shows how many messages it received and when the last one arrived. Leaks become obvious.
Deliver where you want
Per alias: into the inbox, into a folder, forwarded to another address, or both. Create a new alias right from the From field while writing.
Aliases on the Free plan
The Free plan is a forwarding service. You keep your current inbox, and we give you aliases on your own domain or on our shared alias domain that forward to it.
To keep replies private, each forwarded message gets a reverse alias as its reply address. You press reply as usual, we check the reply really came from you, remove traces of your real address and send it from your alias.
A reply through a reverse alias
- A shop writes to
shop@yourdomain.com. - We forward it to your Gmail, with reply address
r.k3j9x2@reply.eoinbox.com. - You reply in Gmail as you normally would.
- We verify it is you, then send it to the shop from
shop@yourdomain.com.
Make aliases from your password manager
Our alias API is compatible with SimpleLogin and addy.io, so tools that support them, like the Bitwarden generator, can create aliases on your domain.
