I made a list of WebMail providers, private or not, to see which ones were actually open source: ### Proprietary [AOL Mail](https://mail.aol.com/ ): Free [Cock.li](https://cock.li/ ): Free [CounterMail](https://countermail.com/ ): Paid [Fastmail](https://www.fastmail.com/ ): Paid [GMX Mail](https://www.gmx.com/mail/ ): Free [Gmail](https://gmail.com ): Free [HEY Email](https://www.hey.com/ ): Paid [Hushmail](https://www.hushmail.com/ ): Paid [iCloud Mail](https://www.icloud.com/mail ): Free [Mail.com](https://www.mail.com/ ): Free [Mailbox.org](https://mailbox.org ): Paid [Mailfence](https://mailfence.com ): Freemium [Outlook.com](https://outlook.com ): Freemium [Posteo](https://posteo.de/en ): Paid [Rediffmail](https://businessemail.rediff.com/ ): Paid [Riseup](https://riseup.net/ ): Free [Runbox](https://runbox.com/ ): Paid [Soverin](https://www.soverin.com/ ): Paid [StartMail](https://www.startmail.com/ ): Paid [Yahoo!

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.
