SimpleLogin

SimpleLogin creates email aliases that forward messages to your inbox while keeping your real address hidden. You can reply to messages or send mail using an alias, and create aliases with a subdomain or a catch-all domain. Users can bring their own domain. With PGP enabled, email is encrypted using the user's PGP key before it is forwarded to a mailbox.

SimpleLogin offers a free plan with 10 aliases, one mailbox, and unlimited bandwidth; reaching the alias cap prevents creating more. Premium costs $36 a year, billed annually at $36/year or monthly at $4, and includes unlimited aliases, custom domains, and mailboxes, as well as PGP encryption. Premium includes Proton Pass premium features, while Free includes its free features. The service lists web, API, self-hosted, browser extension, iOS, and Android options, including Android on F-Droid. Its components are open source and can be self-hosted. Accounts can use TOTP and/or WebAuthn two-factor authentication. SimpleLogin says data is encrypted at rest and that it joined Proton in early 2022.

SimpleLogin provides email aliases with forwarding and the ability to reply or send from an alias. The free plan covers basic alias use, while Premium raises the alias limit and adds features such as PGP encryption.

SimpleLogin suits people who want to use aliases for email while keeping their main address private. It may also suit users who want custom domains, PGP encryption, or self-hosting options.

SimpleLogin is an email-alias service for keeping your real address out of sign-up forms and ongoing conversations. It is best for privacy-conscious users who need to reply or send from aliases, especially those managing their own domains. The free tier is useful for light use, while Premium is the practical choice for extensive alias and encryption needs.

Overview

SimpleLogin forwards messages from disposable or long-term aliases to your mailbox without exposing your actual address. You can also reply to incoming mail and send new messages from an alias, so an alias remains useful after the initial registration. Aliases can be created as needed with a subdomain or a catch-all domain, and you can bring your own domain for addresses under a domain you control.

SimpleLogin joined Proton in early 2022. The service is based in Plan-les-Ouates, Switzerland, while Proton is headquartered in Geneva. Its components are described as open source and self-hostable, giving technically capable users an option beyond the hosted service.

Key features

On-the-fly alias creation suits one-off accounts and services where you do not want to reuse an address. Catch-all support is more useful for a domain-wide addressing strategy, while custom-domain support lets businesses, projects, or privacy-focused individuals keep aliases under their own identity.

Premium adds unlimited aliases and custom domains, catch-all domains, five subdomains, and 50 directories or usernames. Those allowances remove the practical ceiling for users separating many sign-ups, clients, or projects; they are unnecessary if a small set of aliases meets your needs.

Premium also enables PGP encryption. With it enabled, messages are encrypted with your PGP key before forwarding to your mailbox. SimpleLogin says the feature works with Proton Mail and tools including Thunderbird and GPGTools, making it a meaningful option for readers already using PGP rather than a general-purpose replacement for mailbox encryption.

Account protection includes TOTP and/or WebAuthn (FIDO) two-factor authentication. The service says data is encrypted at rest in a PostgreSQL database and that backups older than seven days are deleted. Support is provided by email at [email protected] or through the forum.

Premium and Free both include corresponding Proton Pass features: Premium includes Proton Pass premium features, while Free includes Proton Pass free features.

Pricing

The Free plan is a credible starting point, but its ten-alias cap stops you creating new aliases once reached. Premium is aimed at people who need multiple domains, many identities, more than one mailbox, or PGP. Choose monthly billing for flexibility or the $36 annual price for a full-year commitment.

Platforms

SimpleLogin supports the web, API, browser extensions, Android, iOS, and self-hosting. Extensions are listed for Chrome, Firefox, and Safari; Android is also available through F-Droid. The broad platform mix suits users who create aliases from a desktop browser, phone, or automated workflow.

Who it's for

Choose SimpleLogin if you want separate addresses for services, need to communicate from those addresses, or want custom-domain and catch-all control. Premium is the better fit for domain owners, heavy alias users, and people who use PGP with Proton Mail or compatible tools. Free is sufficient for occasional sign-ups within ten aliases. Users who do not need replies, custom domains, or more than ten aliases may find the paid tier unnecessary.

Pros and cons

Pros

• Replying and sending from aliases protects your real address during ongoing correspondence.
• Custom domains, catch-all addresses, subdomains, and directories support organized multi-identity setups.
• Premium combines unlimited aliases and mailboxes with optional PGP encryption.
• TOTP and WebAuthn, open-source components, and self-hosting options provide stronger control for security-focused users.
• Web, extension, mobile, API, and self-hosted access cover varied workflows.

Cons

• The free plan stops new alias creation at ten, which can quickly limit active users.
• PGP and the larger domain and mailbox allowances require Premium.
• The premium trial has no stated duration, and refunds are unavailable.
• Self-hosting and PGP require more technical involvement than a forwarding-only service.

Alternatives

Verdict

SimpleLogin is a strong choice for anyone who wants private email aliases that remain usable for replies and outgoing mail. Its free ten-alias tier covers modest needs, while Premium earns its price for unlimited aliases, custom domains, multiple mailboxes, and PGP. Look elsewhere if you only need basic forwarding, want a simpler free service, or cannot justify a paid plan once ten aliases are reached.
