I was researching WebMail providers, and noticed that most WebMail providers recommended in privacy communities are labelled as proprietary by AlternativeTo.
I made a list of WebMail providers, private or not, to see which ones were actually open source:
Proprietary
AOL Mail: Free
Cock.li: Free
CounterMail: Paid
Fastmail: Paid
GMX Mail: Free
Gmail: Free
HEY Email: Paid
Hushmail: Paid
iCloud Mail: Free
Mail.com: Free
Mailbox.org: Paid
Mailfence: Freemium
Outlook.com: Freemium
Posteo: Paid
Rediffmail: Paid
Riseup: Free
Runbox: Paid
Soverin: Paid
StartMail: Paid
Yahoo! Mail: Freemium
Yandex Mail: Freemium
Zoho Mail: Freemium
Open source
Criptext: Free
Disroot: Free
Forward Email: Freemium
Infomaniak kMail: Freemium
Kolab Now: Paid
Lavabit: Paid
Mailpile: Free
Proton Mail: Freemium
Roundcube: Free
Skiff/Notion: Freemium
Tuta: Freemium
Unless I’m missing something, it seems like people overlook this when deciding on WebMail providers. Is it a distinction between a proprietary backend server and a proprietary app, or is there a different way to decide if a WebMail provider is proprietary vs. open source? Lavabit was labelled proprietary by AlternativeTo, but open source by Wikipedia.
Note
If I have labelled an open source WebMail provider as proprietary by mistake, please provide evidence by linking to the source code, and I will happily change it.
It is very difficult to run an email provider and not get banned by the others. Google, Microsoft, and Apple control the US market, for example. If they decide your domain is spam, you suddenly can’t email anyone with a Gmail or Hotmail or Apple account. Avoiding getting banned means you have to regulate your own outgoing emails very carefully, rate-limit them just right, and yet also build up a reputation of trustworthiness by sending a lot of emails that don’t get marked as spam.
The only privacy-secure way to do your email would be DIY but this risks getting banned like… all the time.
Personally, I recommend having your own domain and setting up MX records to a reliable email provider that is not one of the big ones and ideally offers some kind of theoretical inbox protection (please note that they could always still read everything if they just copied all incoming messages to another database as well).
Email is itself not very secure. You can use GPG to make it better but most people won’t know how to receive your messages or send secure ones. For security, I recommend using a dedicated e2e chat service or in-person communication.
Yea, people mostly equate email to an electronic letter, but it’s more like an electronic postcard. Anyone handling it can simply read it.
So you’ll want encryption, too. So either you get everyone to use PGP/GPG or get them to use a privacy-by-default provider.
Good luck with the first option and I’m not sure how interoperable the various providers are, so in the worst case you’d have to rally everyone to the same provider.deleted by creator
- Skiff = Notion now, I doubt that it will be open source, but happy to see source code.
- Lavabit open source ? Where’s the code ?
- Roundcube is webmail software, not a webmail provider.
- Mailpile is email software for desktops, not a webmail provider.
Most “privacy” webmail providers, such as ProtonMail, Tutanota, and mainstream services like Gmail, Yahoo Mail, Outlook, and AOL Mail, are labeled as proprietary because they use closed-source software, meaning the code isn’t publicly available for review. These services operate on controlled servers, with features and infrastructures managed entirely by the company. The proprietary nature allows them to implement unique features and monetization strategies, but it also requires users to trust the company’s privacy and security practices without independent verification. This contrasts with open-source alternatives where users can inspect and verify the code themselves.
@Charger8232 Lists from #Alternativeto (which this is based on) are usually not very reliable and show information that just isn’t correct on a service or often includes services that are not real Alternatives to what you were looking for in the first place. The only thing that helps against that is doing your own research.
To pick out one example (I don’t have time to them all): they list #Posteo as being proprietary which just isn’t correct. That company is as #opensource as they come.
@Charger8232 @g0nz4 I guess in that case “proprietary” refers to the owners of the platform itself but not to the code of software. But then, they should make the distinction between proprietary/communitary and open source/proprietary code. Even between free/paid services. So, IMO that list from alternativeto is confusing.
Posteo is in fact open source.
