How to Create Email Aliases in Mailbux

An email alias is an additional address that delivers into an existing Mailbux mailbox. Create [email protected], [email protected], and [email protected] as aliases on your personal mailbox, and every message lands in the same inbox — no second login, no extra storage, no per-address fee. This guide walks through the exact steps in your Mailbux dashboard.

What is an Email Alias?

An alias is a virtual address. There's no separate inbox behind it — mail sent to the alias is delivered straight into the mailbox you attach it to. One real mailbox can hold several aliases.

Aliases are the right choice when:

• You want one inbox to receive mail addressed to multiple role addresses (info@, support@, sales@, hello@).
• You want to publish a different address for each context (website, podcast, newsletter, vendor signups) but read them all in one place.
• You want an extra address without using any of your plan's storage.

If you need separate inboxes — for example because a different person owns each address — create a dedicated mailbox instead and skip this guide.

Before You Start: The Domain Must Exist

Aliases can only use domains that are already added and DNS-verified on your account. The alias domain dropdown inside the dashboard only lists domains from your Domains page.

If the domain you want isn't there yet: open Manage → Domains → Add domain, enter the domain, and publish the records shown in Manage → DNS (MX + SPF). Wait for it to show as verified, then come back to this guide.

Step 1: Open Aliases

Sign in to dash.mailbux.com and open Services → your plan → Manage → Aliases.

Step 2: Pick or Create the Mailbox That Will Receive the Alias Mail

An alias always delivers into an existing mailbox. If you don't have the right one yet, create it first in Manage → Mailboxes → Create mailbox (address, password and at least 1 GB of storage).

Step 3: Add the Alias

In Manage → Aliases, add an alias: pick the alias address (for example info@, support@ or sales@) and the existing mailbox it delivers into, then save. The alias is live immediately.

Step 4: Use Any Domain on Your Plan

The alias can use any domain on your plan. To add another one, open Manage → Domains and publish its records from Manage → DNS.

Step 5 (Optional): Set Up a Catch-All

A catch-all captures mail sent to any address on a domain, even addresses that don't exist. It is useful when you want nothing to bounce, but it attracts more spam than specific aliases.

Open Manage → Catch-all and, per domain, choose ONE existing mailbox to receive that mail. To reach an outside address, add a forwarder from that mailbox in Manage → Forwarders.

Step 6 (Optional): Send From Your Aliases

Aliases receive mail out of the box. To send from an alias, add it as an additional sending identity in whichever mail client you use:

• Mailbux Webmail — when composing, pick the From address from the dropdown above the To field.
• Outlook / Apple Mail / Thunderbird — add the alias as an additional sending identity in account settings, using the same IMAP/SMTP server settings as your main mailbox (see IMAP/SMTP settings). When you reply to mail sent to the alias, the client will usually pick the alias as the From address automatically.

Common Questions

How many aliases can I have?

The Free plan includes up to 5 aliases; paid plans include unlimited aliases (fair use). There's no extra charge — aliases use zero storage because they deliver into the existing mailbox.

Can one alias go to multiple mailboxes?

An alias delivers into exactly one mailbox. If you need a single address to fan out to multiple inboxes — for example support@ reaching three team members — use a forwarder instead: Manage → Forwarders sends mail from an existing mailbox to one or more addresses.

Can I use an alias on a different domain from my main address?

Yes, as long as the alias domain is on your Mailbux account and DNS-verified. The domain list in Manage → Aliases shows every domain on your plan.

Do I need a separate password for the alias?

No. The alias has no login of its own. You sign in with the underlying mailbox's address and password, and the alias mail is just there in the same inbox.

Can I delete an alias later?

Yes. Open the mailbox in Edit Account, find the alias row in the Email Aliases/Catch-All section, click the red remove button on that row, and save.

Does Mailbux have shared team inboxes with assignment and internal notes?

No — Mailbux is an email hosting platform, not a help-desk tool. For team-shared role addresses, the standard patterns are: share one mailbox login, add the role address as an alias on each team member's mailbox, or set up a forwarder that fans out to multiple mailboxes. If you need ticketing, assignment, or internal notes, run a dedicated help-desk product on top of your Mailbux email.
