How to Add Email Aliases in Tuta (and the Limits)

An alias in Tuta is a second address that lands in the same inbox as your main account, with no separate password and no separate mailbox to check. You add it once in settings, then send and receive from either address interchangeably.

The mechanics are simple. The limits and the edge cases — what happens when you delete one, whether the free plan gets any at all, how it differs from adding a whole second user — are where people get stuck. This post covers both.

Before you start#

You need a paid Tuta plan. The free tier does not include alias creation — it's one of the first things that separates free from Revolutionary/Legend on Tuta's pricing page.

You also need to know which domain you're aliasing on. Tuta gives every account a handful of built-in domains to pick from, and separately supports verified custom domains for a business or personal brand.

• A Revolutionary, Legend, or a legacy paid Tuta plan active on your account
• Access to Settings in the Tuta web app or desktop client
• If using a custom domain: DNS access to add the verification records first (covered in a separate post, not here)

Steps: adding an alias in Tuta#

1. 1

   Open Settings

   In the Tuta web app, click your account name or the gear icon, then go to Settings.

2. 2

   Go to Login credentials

   Find the "Login credentials" section. This is where Tuta lists your primary address and any aliases already on the account.

3. 3

   Click "Add alias"

   A new row appears with a text field for the local part (the bit before the @) and a dropdown for the domain.

4. 4

   Pick a domain

   Choose one of Tuta's built-in domains — tuta.com, tutanota.com, tutamail.com, or tuta.io — or a custom domain you've already verified on the account.

5. 5

   Type the local part and save

   Enter the name you want before the @ and confirm. Tuta checks it isn't already taken on that domain, then activates it, usually within a minute or two.

6. 6

   Confirm it's active

   The new address appears in the Login credentials list marked as active. It's now a valid receiving address, and available in the composer's "From" dropdown for sending.

Can you send from a Tuta alias?#

Yes. Once an alias is active, it shows up in the "From" field of the composer alongside your main address. Pick it before you write, and outgoing mail carries that address in the header — the recipient sees the alias, not your primary account, unless you set up a reply-to that says otherwise.

There's no extra login step and no separate outbox. It's the same account, the same Sent folder, just a different address on the envelope.

Tuta alias limits per plan#

Alias allowance is one of the concrete differences between Tuta's tiers. Free accounts get none. Paid tiers get a fixed number, and that number is part of what you're paying for if aliases matter to you — check the current allowance on Tuta's own pricing page before you commit, since plan names and counts have shifted before and will again.

Tuta alias vs. an additional user#

These solve different problems and it's easy to reach for the wrong one. An alias is a second address on one mailbox — one inbox, one set of folders, one password. An additional user (available on Tuta's Teams-oriented plans) is a genuinely separate mailbox with its own login, its own storage allocation, and its own inbox that doesn't merge with yours.

If you want "mail sent to hello@ and to me@ both land in the inbox I already check," that's an alias. If you want a coworker or a second identity to have their own private mailbox under one billing account, that's an additional user.

How to delete an alias in Tuta#

In Settings > Login credentials, find the alias and use the deactivate or remove option next to it. Deactivating stops new mail from being accepted at that address immediately; the alias disappears from your "From" dropdown right away too.

Reactivating a deleted Tuta alias#

Within the holding period, Tuta may still show the address in your account's history with an option to reactivate it, restoring it to active status on the same account. Once that window passes, the address is released and can be registered by anyone, including a stranger — Tuta does not guarantee it stays reserved for you indefinitely.

If an alias mattered to you — it's printed on a business card, or contacts have it saved — reactivate it inside that 30-day window rather than waiting to see what happens.

What to do when it doesn't work#

A faster way to manage many addresses#

Aliases solve the address side — one inbox, several names people can reach you at. They don't do anything about what happens once mail from all of those addresses lands together: sorting a hello@ inquiry from a personal reply from a notification, deciding what needs an answer today.

AI Emaily connects to any IMAP account, including Tuta, and layers automated triage, drafting and filing across every address feeding one inbox — so the alias sorts your senders, and the agent sorts your replies. Every send stays approve-before-it-goes; nothing goes out without you seeing it first. We build AI Emaily. If you're weighing whether the manual alias setup above is worth the trouble, a 7-day free trial on the Pro plan (card required, $0 if you cancel before day 7) is enough to see whether the automation earns its keep.
