SimpleLogin gives you separate email addresses for websites and contacts, then forwards incoming messages to a mailbox you already use. You can reply from an alias, disable individual aliases when they start attracting unwanted mail, and keep your real mailbox address out of ordinary correspondence. It is a way to manage address exposure—not a guarantee of anonymity or a shield against every kind of tracking.
What SimpleLogin does
An email alias is a separate address that forwards messages to your chosen mailbox. Instead of giving a website your everyday address, you give it an alias. SimpleLogin routes incoming mail for that alias to you. When you reply through the supported workflow, the recipient sees the alias rather than your mailbox address.

Aliases are persistent unless you delete them. If one becomes a source of spam or unwanted contact, you can disable it individually rather than changing the address you use everywhere else. That makes aliases useful for separating sign-ups, services, and contacts, and for identifying which address is receiving unwanted mail.
An alias does not make you anonymous to the service you email. A site may still identify you through an account, payment, device or other information, and email content or links can still be used for tracking. SimpleLogin limits disclosure of your mailbox address; it does not remove those other signals.

How to create and use aliases
Choose a random or custom address
SimpleLogin supports randomly generated aliases and custom-named aliases. Random options can use random words or UUID-style text. A custom name can make it easier to remember which site or purpose an address belongs to; documentation also describes adding a note for that purpose. See SimpleLogin’s getting-started guide.
Forward messages to your mailbox
You can add and verify mailboxes, then choose which mailbox or mailboxes receive messages for an alias. The mailbox remains your normal destination for reading email; SimpleLogin handles the alias routing. Its mailbox documentation explains adding and selecting destinations.

Reply or start a new conversation
When a message arrives through an alias, you can reply using your regular email client. SimpleLogin routes the reply so it comes from that alias, keeping your mailbox address hidden from the original sender. To initiate a message to a new contact from an alias, you first create a reverse alias for that contact. SimpleLogin documents this new-outbound-message feature for paid plans, including Premium and Proton Pass Plus or higher. Details are in the FAQ and sending guide.
Catch-all domains and directories are additional ways to create aliases on the fly, rather than setting each one up in advance. Catch-all and custom-domain features are Premium plan features according to the current pricing page.
Free and Premium plans
SimpleLogin’s official pricing page currently lists the following plans. Prices and included bundles can change, so verify the pricing page before subscribing.
| Plan | Published price | Published limits and features |
|---|---|---|
| Free | $0 | 10 aliases; one mailbox; unlimited bandwidth; reply from alias; browser extensions; iOS and Android apps; TOTP and/or WebAuthn (FIDO) account security; Sign in with SimpleLogin. |
| Premium | $36 per year or $4 billed monthly | Unlimited aliases; custom domains; catch-all; new outbound messages from aliases; five subdomains; 50 directories/usernames; unlimited mailboxes; PGP encryption; Proton Pass Premium features. |
The practical dividing line is not simply whether you can forward mail: the Free plan includes forwarding, one mailbox, and replies from aliases. Premium raises the alias limit and adds features such as custom domains, catch-all, more mailbox options, and initiating new messages from aliases.

What happens if Premium ends?
SimpleLogin says aliases already created continue receiving and sending mail after a subscription ends. If you have more than the Free plan’s 10-alias limit, you cannot create additional aliases; you also cannot add a new domain, directory, or mailbox while over the applicable free-plan limits. Check the subscription FAQ for the current account behavior.

Account security and who operates SimpleLogin
SimpleLogin supports TOTP and WebAuthn (FIDO) account security. Registering a WebAuthn security key is optional; it is an account-protection accessory, not a requirement for using aliases. The security setup documentation describes registering a key.
SimpleLogin says the project began in 2019, the company was created in 2020, and the service joined Proton at the beginning of 2022. Its About page identifies Proton AG as the product owner: SimpleLogin’s About page.
Quick Recap
What to consider before relying on aliases
- Address separation: An alias helps avoid giving every site or contact the same mailbox address, and lets you disable an address independently.
- Service dependency: SimpleLogin sits in the mail-routing path and manages your aliases. You are trusting a third party with that routing and account-management role.
- Not complete anonymity: The recipient sees the alias, but that alone does not prevent identification through account details, message content, links, or other tracking methods.
- Plan fit: The Free plan is limited to 10 aliases and one mailbox; consider whether you need custom domains, catch-all, additional mailboxes, or new outbound messages before choosing a plan.
