Our verdict on each
addy.io
addy.io suits people who want a fresh address for every site without a new mailbox for each one, and it starts on a free plan. Paid tiers begin at $1, under the €4.38 secure email median, though stored mail is not end-to-end encrypted.
Proton Pass

The provider also lists apps for Android, iOS, Windows, macOS and Linux, and says all fields, including usernames and web addresses, are encrypted. These are provider descriptions, not an independent security assessment.

Pros and cons
addy.io
Pros
- The free plan allows unlimited standard aliases, plus shared domain aliases and alias domains, so building a large set of addresses costs nothing.
- Custom domains are supported, so aliases can sit on a domain you already own instead of a shared one.
- Open source, so the alias and forwarding logic can be read and checked by anyone.
Cons
- Support runs on email, help centre and community, so anything urgent waits for a written reply or a community thread.
- The free plan's recipient limit and monthly bandwidth allowance are tight, so more than light forwarding means paying.
- Jurisdiction is GB, which puts the contract and any dispute under a single country's rules.
Proton Pass
Pros
- The listed free-plan features include unlimited logins, notes and credit cards, plus unlimited devices.
- The provider lists 10 hide-my-email aliases and passkey support.
- Apps are listed for Android, iOS, Windows, macOS and Linux.
Cons
- Vault contents cannot be unlocked by the company, so a lost route to the account leaves no fallback
- Built around a single account holder, so unlocking the vault depends on that person's own care
Who each suits
addy.io
Who it suits
- People signing up to lots of sites who want a new alias for each and can begin on the free plan.
- Readers who want custom domains on an address they own, with apps across browsers rather than a system-level setting.
- Users happy to forward mail onward and who judge the service on open source and price rather than on encrypted storage.
Who should look elsewhere
- Anyone who needs end-to-end encrypted mail storage: addy.io encrypts only forwarded messages, and Posteo at €1 is the other option here at a close entry price.
- Apple users already set up inside that ecosystem, where Apple's alias generator at $0.99 is the shorter path, while addy.io's $1 buys open source aliases across iOS, Android and Web.
Proton Pass
Who it suits
- People who want a password manager with listed apps across desktop and mobile platforms and passkey support.
Who should look elsewhere
- People who want a password manager that the provider can unlock for them
- Anyone wanting a tool limited to one type of device

Questions about each
addy.io
Is there a free plan, and what comes with it?+
Yes. The free plan allows unlimited standard aliases, and adds shared domain aliases, alias domains, a recipient limit and a monthly bandwidth allowance. That is enough for light use without paying anything. Beyond that, paid plans in the free and budget range start at $1.
How much does addy.io cost at the entry point?+
Entry is $1, which sits under the €4.38 median for secure email brands and below the €8.94 upper marker. You can also stay on the free plan as long as the allowance suits, which is the practical way to judge the service first.
Proton Pass
Which platforms are listed for Proton Pass apps?+
The provider lists Android, iOS, Windows, macOS and Linux.
Can outside experts check how the software works?+
The code behind the software is publicly available, so people outside the company can review it. This openness is part of its approach to transparency. Anyone who wants to understand how vault contents are protected can look at the encryption design, since only the account holder can read stored items.
