Email Aliases and Compartmentalisation

Updated 13 Oct 2026 3 min read

Aliases are extra @prmail.uk addresses that deliver to your PrMail inbox. This guide shows how to create and manage them, and how to use anonymous identities for sign-ups.

Why use aliases

If you use one address everywhere, one data breach exposes it to every spammer and data broker. Give each service its own alias instead. If an alias starts getting spam, you know who leaked it, and you can pause or destroy that alias without touching your main address.

For example, if your address is [email protected], you might sign up to a shop with [email protected] or a random alias like [email protected].

How many aliases you can have

  • PrMail Pro (including PrMail included with a VPN plan): 5 aliases.
  • PrMail Business: 20 aliases.
  • PrMail Free: no aliases.

The Aliases section in Settings shows how many you've used, for example 2 of 5. Paused aliases still count.

Create an alias

  1. Go to PrMail › Settings and scroll to Aliases, or click Aliases under Privacy tools in the PrMail panel.
  2. Click New alias. (The button only appears while you're under your limit.)
  3. Optionally add a Label, such as "Amazon" or "Newsletter", so you remember what it's for.
  4. Either type a Custom address and click Create alias, or leave it empty and click Random address for an address made of 8 random letters and numbers.

Custom addresses follow the same rules as your main address: 3 to 32 characters, using letters, numbers, dots, hyphens and underscores, starting and ending with a letter or number.

Manage your aliases

Each alias in the list shows its label, whether it delivers to your inbox or is paused, and any spam reports.

  • Copy: copies the address so you can paste it into a sign-up form.
  • Pause: the alias stops receiving mail. Use this to cut off a service without deleting the address.
  • Resume: turns a paused alias back on.
  • Spam: records a spam report against the alias. After 5 reports, the alias is paused automatically.
  • Destroy: permanently deletes the alias. This can't be undone.
Pause or destroy? A destroyed address is released, so it could later be registered as an alias by someone else, who would then receive anything still sent to it. If a service might keep emailing an address, pause it rather than destroying it.

Anonymous identities

For sign-up forms that ask for more than an email address, PrMail can generate a complete made-up persona: a name, username, date of birth, gender, city and country. If you have a PrMail mailbox, each identity also gets its own random alias that delivers to your inbox.

  1. Click Identities under Privacy tools in the PrMail panel, or open Anonymous identities.
  2. Optionally add a Label and choose a Gender (or leave it on Random).
  3. Click Generate identity.
  4. The identity's details are shown on its card. Use the copy button next to each field, or Copy all details.

Use the New buttons to make up a new name, location, birthday or username on its own, Edit label to change the label, or Delete to remove an identity. Deleting an identity also removes its alias. The page shows how many identities you've used and how many your plan allows.

Identity aliases appear in your alias list with the label "Identity: (name)", and they count towards your alias total.

Use generated identities for privacy, not where the law or a contract requires your real details, such as banking, travel or official forms.
