The alias-specialized Proton Pass alternative

Aliases on a shared provider domain (e.g. @emailalias.io) aren't portable — they live on our domain and stay with us. Aliases on a custom domain (yourdomain.com) are fully portable: you keep the domain, point its MX records at a new provider, re-create the same local-parts on their side, and the addresses keep working — provided the new provider supports custom local-parts (most do; some only issue random codes). Custom domains are a Premium feature on EmailAlias, but for anyone who plans to use aliases long-term, it's vendor-independence insurance worth having.

Unlimited aliases, up to 5 custom domains, unlimited verified forwarding inboxes (so each alias can route to the right mailbox), send & reply from any alias, real-time leak detection with exposure analytics, and priority processing — all for $4/month or $35/year (save 27%).

Because each service has its own unique alias, you'll know exactly which service leaked your data — when spam or phishing hits that alias, the source is obvious. Our exposure intelligence engine also flags suspicious senders in real time. Disable the affected alias and your real email stays safe.

Proton acquired SimpleLogin in 2022 and integrated its alias backend into Proton Pass. The SimpleLogin website and tier still exist, but most new users land in Pass. If you're comparing Pass aliases, you're effectively comparing SimpleLogin's engine with Proton's password-manager front-end on top. The alias mechanics are the same; the difference vs EmailAlias is sender-risk scoring, exposure analytics, and our REST API + MCP server.

If you don't already have a password manager and you specifically want one tied to your aliasing service, Pass is a reasonable choice. EmailAlias is alias-specialized — we don't try to be a password manager. Many users pair EmailAlias with 1Password, Bitwarden, or KeePass (which they were already using) instead of switching to a bundled product. It depends on whether you want one tool that does both okay or two tools that each do their job well.

No. Pass's privacy story is the encrypted vault + the alias — sender-risk intelligence isn't part of the product. EmailAlias runs continuous risk scoring on every inbound message (risky TLDs, typosquatting, phishing keywords) and surfaces a per-alias risk dashboard plus real-time alerts when a high-risk sender hits an alias. That's the main thing this page exists to highlight.

Aliases on @proton.me / @passmail.com / shared Pass domains stop working when you cancel Proton — those addresses are tied to the account. Custom-domain aliases are portable if you used Pass Plus's custom-domain feature: repoint MX records to a new provider, re-create the local-parts, and the addresses keep working. EmailAlias supports the same custom-domain portability without requiring a separate ecosystem subscription.

Not for aliases at the time of writing. Proton publishes APIs for some Proton services, but Pass alias management is primarily UI-driven. EmailAlias ships a REST API and an open-source MCP server so AI assistants (Claude Desktop, Cursor, Zed, ChatGPT Custom GPTs) can create, list, and audit aliases conversationally — useful if you want to script bulk alias creation, integrate with internal tooling, or chat with your inbox.
