SimpleLogin

SimpleLogin gives you separate email addresses that forward to your inbox, while preserving the option to reply or send from an alias. It is best suited to people who want control over the addresses they share, including those who need custom-domain or self-hosting options. The free plan is a useful starting point, but its ten-alias ceiling makes Premium the practical choice for heavier use.

Overview

Unlike a forwarding-only address, a SimpleLogin alias can remain the sender address when you reply or initiate a message. That makes it useful for ongoing correspondence as well as signups where you want to keep your real address private. Aliases can be made on the fly with a subdomain or catch-all domain, and users can bring their own domain.

Key features

Alias creation is flexible, but the free plan puts a firm limit on expansion: once you have ten aliases, you cannot create more. For a small set of signups that may be enough; people separating many services or identities will need Premium to avoid managing around the cap.

Premium allows unlimited aliases and custom domains, catch-all domains, five subdomains, and 50 directories or usernames. Unlimited mailboxes also make it more accommodating for users routing aliases to multiple inboxes. These tools are valuable for a larger personal setup, though they are overkill if a handful of aliases does the job.

Premium also enables PGP encryption, encrypting email with your PGP key before forwarding it to your mailbox. SimpleLogin says this works with Proton Mail and other PGP tools, including Thunderbird and GPGTools. It supports TOTP and/or WebAuthn (FIDO) for two-factor account security. The service says its components are open source and can be self-hosted, which suits users comfortable managing their own deployment.

The service says data is encrypted at rest in a PostgreSQL database and that backups older than seven days are deleted. Premium includes Proton Pass premium features, while Free includes Proton Pass free features. Support is available by email or through the forum.

Pricing

The Free plan costs nothing and includes ten aliases, unlimited bandwidth, one mailbox, browser extensions, iOS and Android apps, TOTP and/or WebAuthn, and Sign in with SimpleLogin. It is a sensible way to start, but the alias limit prevents continued alias creation once reached.

Premium costs $36 a year, billed $36/year or $4 billed monthly. It removes the alias cap and adds unlimited custom domains, catch-all domains, five subdomains, 50 directories or usernames, unlimited mailboxes, and PGP encryption, along with Proton Pass premium features. Choose it if you need those expanded limits or encryption; otherwise the free plan retains the core forwarding and alias-sending functions.

The service does not offer refunds, so the monthly billing option may suit readers who want to avoid committing to an annual term.

Platforms

SimpleLogin supports web, Android, iOS, browser extensions, an API, and self-hosting. Its site identifies Chrome, Firefox, and Safari extensions, with Android apps also available through F-Droid. This range suits users switching between desktop and mobile, as well as those who want a programmatic or self-managed option.

Who it's for

SimpleLogin is a strong fit for people who want aliases that support replies and outbound mail, not just forwarding, and for users who want custom domains or a large collection of addresses. The free tier works for modest needs. If you expect to create aliases regularly, or want PGP, Premium is the relevant plan. Users who only need a small number of forwarded addresses may not need its extra domain and identity controls.

Pros and cons

Pros: Aliases support both replies and sending, so they can be used for real correspondence rather than only receiving forwarded messages.

Pros: Premium combines unlimited aliases and custom domains with catch-all domains, multiple mailboxes, and PGP encryption.

Pros: Web, mobile, browser extension, API, and self-hosted options cover a wide range of ways to use the service.

Cons: Free users cannot create aliases beyond the ten-alias limit, a meaningful constraint for anyone building a larger set of identities.

Cons: There are no refunds, so buyers should be comfortable with the chosen billing term.

Alternatives

DuckDuckGo Email Protection is a free alternative with email forwarding, tracker removal, and personal and private Duck Addresses; choose it if those features meet your needs without SimpleLogin's paid alias and domain tools.

addy.io has a free plan with unlimited standard aliases, ten active shared-domain aliases, one recipient, and two available alias domains. It may suit someone whose needs fit those stated free-plan limits.

Firefox Relay is another freemium email-alias option.

GridInbox offers a free plan with five aliases, 10 outbound messages per month, 50 inbound messages per month, 512MB storage, a 5 MiB attachment limit, and REST API access. Choose it if those quotas and API access better match your use.

MailPal is a free option for users who want an open-source, auditable project with web, desktop, API, and self-hosted platform support.

AliasVault combines email aliases with password management, a built-in 2FA authenticator, and full offline mode in its free plan.

anon.li is a freemium, open-source alternative with web, API, and extension support.

33Mail has a free Lite plan with 10MB monthly bandwidth and aliases limited to five per 30-minute period; its $1 per month Premium plan raises bandwidth to 50MB monthly and allows 20 anonymous replies.

Verdict

Choose SimpleLogin if you want aliases that can handle replies and sending as well as forwarding, especially when custom domains, catch-all addresses, or multiple mailboxes matter. Its free plan is capable but deliberately bounded at ten aliases; the main reason to look elsewhere is if that cap or Premium's price is hard to justify for a small, forwarding-focused setup.
