Replacements
Listings that take over the same core job as ElectronMail.
Proton Mail
Official Proton Mail apps for reading and sending end-to-end encrypted email on phones, desktops and the web.
Proton Mail's official apps cover desktop, mobile and web with the calendar included, but they are closed source and the desktop apps need a paid plan after the trial.
Proton Mail Bridge
Local gateway that lets standard mail clients read a Proton Mail account.
Proton Mail Bridge lets Thunderbird, Outlook or Apple Mail read a Proton account through a local IMAP and SMTP server, but requires a paid Proton plan.
Also worth comparing
These listings name ElectronMail as their own alternative, so the relationship runs both ways.
Tuta Desktop
The desktop client for Tuta's encrypted mail service, with end-to-end encrypted mail, calendar and contacts.
ElectronMail is an unofficial open-source desktop client for Proton Mail on Windows, macOS and Linux, so switching also means moving to a Proton account.
