Our verdict

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.

Pros and cons

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.
  • Entry at $1 sits under the €4.38 median for secure email brands.
  • Apps reach iOS, Android and Web, covering phones, browsers and the main extensions.

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.

Scored 9.5 / 10 by ShieldCue.

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.

What it does well

Aliases here are addresses, not mailboxes. You point them at the same inbox and hand out a different one per site, which keeps sign-up forms away from your real address. The free plan covers the core job generously: unlimited standard aliases, with shared domain aliases, alias domains, a limit on recipients and a monthly bandwidth allowance on top. Custom domains are supported, so the addresses can sit on a domain you already own rather than on a shared one. That pairing is the part that stands out, breadth of aliases on the free plan plus the option of your own domain, and it suits people who live in their inbox across many sites.

Privacy and jurisdiction

The terms sit under GB law, which puts the contract and any dispute in a single jurisdiction. Logging is light in the ways that matter for advertising: analytics are self-hosted Umami with no cookies and no personal data, and no Google Analytics runs. Server access and error logs do record IP addresses, rotated each day and kept only briefly, and used to improve the service and prevent abuse. The bigger question is what sits in the mailbox. Stored mail has no end-to-end encryption. What addy.io can do is encrypt a forwarded message with GPG/OpenPGP against the recipient's own public key, attachments included, with the subject line optionally encrypted too. In practice the alias hides your real address, not the content of what you receive.

Who runs it

The team is based in the United Kingdom, the same country that sets the terms, so the company and its contract sit together. Support runs on email, help centre and community: email for anything specific, the help centre for the common ground, and the community for longer threads. It is a self-serve setup that suits an audience comfortable reading documentation, and answers arrive in writing at whatever pace each channel moves.

Frequently asked questions

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.

Is my mail end-to-end encrypted?+

Stored mail has no end-to-end encryption, so what sits in the inbox is readable on the service side. Forwarded messages can be sent with GPG/OpenPGP encryption to the recipient's own public key, attachments included, with the subject optionally encrypted. That is a different model from the 77.8% of secure email brands on this site, which keep stored content unreadable to the provider.

Where is the company based and which law applies?+

The team sits in GB and the terms are under GB law, so a single legal system covers the contract and any dispute. That keeps the legal picture short for a service that forwards mail onward rather than holding a full mailbox.

Is addy.io open source?+

Yes, the code is open source, so the alias and forwarding logic can be read and checked by anyone, and run yourself if you want to host it. Open source is not the norm here: it covers 69.8% of the secure email brands on this site.

Which devices and browsers can I use?+

Apps cover iOS, Android and Web. Phones, the web app and the major browsers are all handled, and Raycast is there for people who live in a launcher. You can manage aliases wherever you sign up, without hunting for a separate tool per device.

How do I get help if something goes wrong?+

Support runs on email, help centre and community. Email suits anything specific, the help centre covers the recurring questions, and the community is where longer threads get worked out. Plan for a written answer rather than a live one, and keep the alias you are troubleshooting in the subject line.
