Comment summary: Addy.io is praised for its privacy features, sleek interface, and functionality as a superior alternative to burner mail services. Users appreciate its flexibility in handling subdomains and custom domains, as well as the ability to self-host. However, concerns are raised about potential spam vulnerabilities and issues with email delivery. While many find the tool indispensable for online privacy, one user expressed dissatisfaction with bandwidth management and delivery explanations being premium features.

Best alternative to burner mails.

Great tool to hide your email. Servers are in the Netherlands (not too bad), the web-UI is excellent (sleek, self-explaining and simple), chrome, brave, opera extensions work well. This is a must have tool for all privacy conscious people on the web.

DO NOT RELY ON THIS APP.

E-mails fail to deliver for no apparent reason (explanations of failed deliveries is a premium feature), no warning when you are getting close to your bandwidth limit, very hard to manage bandwidth as it is impossible to tell which aliases are using the most of it.

Started using it to improve my privacy. Nightmare app. Wish I had never used it.

Amazing tool, I also find it a big plus that you can self host it. I would definitely recommend it to anyone that cares about security and privacy. The interface is simple sleek.

But couldn't a sophisticated spammer harvest the user's email root domain (eg, @myusername.anonaddy.com) and start spamming random email addresses using that root, especially since anonaddy.com (and also bulc.club and others) by default allow the first email sent to an address to go through? How might one avoid such a hack as spammers often adapt fast?

Great question! The real power of BULC CLUB, beyond other email forwarders (and Plus Addressing, like GMail's), is the folksonomy-based filtering. We harness the power of our Membership to regularly block spammer addresses and domains, preventing their emails from ever forwarding to your inbox. It's our hope, with your continued support, that we'll be able to maintain the world's most accurate and current catalogue of spammers. To our knowledge, no other free service can claim the same.

Thanks for your inquiry, support, and referrals. Please let us know if you have further questions.

It is great email alias solution and more. I recommend this and SimpleLogin. AnonAddy is cheaper and easier to use but not as feature rich. SimpleLogin is much more powerful but that also adds complexity for those looking for the easiest email aliasing solution that works, secure, privacy focused, and more. I recommend paying the Lite plan for $12 for the entire year to support a great project and not put all your eggs in one product.

For the price

Pleased! Temporary emails that last as long as you want. They can be changed at will and will forward to your choice of email address. The free part is generous.

What is addy.io?

Addy.io is an open-source anonymous email forwarding service.

Why should I use addy.io?

  • Protect your real email address from spam by simply deactivating/deleting aliases that receive unsolicited emails
  • Identify who has sold your data by using a different email address for every site
  • Protect your identity in the event of a data breach by making it difficult for hackers to cross-reference your accounts
  • Prevent inbox snooping by encrypting all inbound emails using GPG/OpenPGP encryption
  • Update where emails are forwarded without having to go through and change your email address for each site individually
  • Reply to forwarded emails anonymously without revealing your true email address

How does it work?

  1. Register your username

Let's say your username is johndoe. You can now use *@johndoe.anonaddy.com (or .me) as your email. Where * denotes any valid local part for an email address.

If you would like to remain anonymous choose a username that is not linked to your real name or identify and that you haven't used anywhere else.

  1. Create Aliases On The Fly (or generate UUID aliases)

Next time you are signing up to a website or newsletter, simply make up a new alias and enter that instead of your real email address.

For example, if you are on vuejs.org and you want to sign up to their newsletter you could simply enter vuejs@johndoe.anonaddy.com (or .me).

We'll automatically create the alias in your dashboard as soon as it receives its first email. You can reply to emails anonymously too!

  1. Manage Aliases

Let's say a spammer gets hold of one of your aliases and starts sending unsolicited email to it. You can simply toggle a switch in your dashboard and deactivate that alias.

Our system will then silently discard any further emails and you won't be forwarded anything else for that alias.

You can also delete the alias. Then our system will reject any emails and respond with an error.
