ElectronMail VS proton-api

an application i use a lot is electronmail, the only problem with it is it's only aur package is a binary that bundles it's own electron. if you could make a package that built it from source and used system electron i would greatly appreciate it!

Using Electron-Mail as a Desktop client on multiple devices (Windows, Linux, MacOS) and can say nothing bad about it - it's basically an electron wrapper with added features - I like having my email in a dedicated app. https://github.com/vladimiry/ElectronMail You could also install the website as an app (should work in most browsers).

Electron-Mail offers offline access/ a database. https://github.com/vladimiry/ElectronMail

You van use Electronmail to do this in the meantime: https://github.com/vladimiry/ElectronMail

also you can look into ElectronMail, which is basically what the official desktop app will probably more or less be

It's not self-hosting, but ElectronMail lets you use ProtonMail in an electron app using their frontend code.

Is there a reason that everyone is asking for an official client and not just using ElectronMail? It's had support for Drive for months

The general go-to recommendation for cross-platform email clients is Mozilla Thunderbird (PrivacyGuides, OpenSource.com). I like to be able to have access to my emails offline and currently, I am using ElectronMail, which encrypts the offline datastore with a password that has be input every time the application is launched (GitHub README.md).
