Default email app on iOS

[ganthern]

As an owner of an iOS device i want to be able to configure the Tutanota app as the default email app. When clicking on a email address (e.g. from address book or a mailto link) the Tutanota application should start and open an email editor.

Acceptance critera:

• In the Settings of the iOS device under "Settings > Mail > Default mail app" Tutanota should appear as default mail handler
• Clicking on an email address from the native address book should start Tutanota and open an email editor with that address as recipient
• Mailto links within a web browser should also start Tutanota and open an mail editor (including recipient, subject, body if specified)

Implementation hints:
This is supported since iOS 14 and it seems that this kind of integration is based on passing around mailto links. As the web view can already handle mailto links we just have to forward the mailto link from the native part to the web view when the application is invoked. To enable the default mailto integration just have to set a property and ask apple for permission.

Here is what we need to do to prepare:
https://developer.apple.com/documentation/xcode/preparing-your-app-to-be-the-default-browser-or-email-client

Some links how native side will receive these links

I contacted apple to request permission to enable tutanota as a default mail client. I finally got a response with some dot points:

The application does not take the ‘mailto:’ URL scheme. This means that it is not contained in the CFBundleURLSchemes member of the CFBundleURLTypes dictionary in the Info.plist.

This implies we should be able to get a test version of the app working and enabled for mailto, which we would then submit for review, however I spent some time looking into this and couldn't get it to build due to the missing permission (maybe i was confused about something)

The application requires an account, and no test credentials were provided.

The owner of the developer account probably needs to make the request rather than myself

Hi,

Has there been any progress on this?
Is there any way someone outside Tutanota could help with?

It is scheduled and some research was made but it wasn't in development yet. We've been also offset by waiting for permission from Apple which we do have now I believe.

So, when is it coming?

4 years later and this is still an existing issue?
Other free apps have this from day 1, so why tuta still doesn't have it ?

Tuta won me with the price \ features ratio, mainly for being able to use unlimited custom domain aliases ❤️ , but not having it as default app got me off guard and searching on google to see if i did something wrong until i stumbled on this open issue. 🤯
