The ProtonMail app is open source: https://github.com/ProtonMail/proton-mail-android https://github.com/ProtonMail/proton-mail-android As is the bridge, and others. I moved over ~6gb of emails without issue. I set up the bridge and transferred everything from Google to ProtonMail.

I don’t have that much emails and faced lots of issues with the import tool, moving from a gmail account. After more than 10 attempts and 3-4 exchange with their support I still have a few emails that haven’t been imported successfully. Other than that I’m a happy user. But I think that they should invest more in the bridge and importer/exporter tool, the user experience really isn’t that great.

  Could be a matter of the client I use. I use Outlook; what are you using?

  yes, very interested in the emails you can't import. I don't work for ProtonMail btw, just have quite bit of experience with smtp and email. Just curious from a tech perspective what kind of email you are having trouble importing.

    I had tons of issues with mailman added headers causing entire HTML messages to be interpreted as plain text, rendering their encoding tags visible. I think they fixed this. I was still a bit surprised that this was an issue 1+ years into the IMAP bridge. Big plus is that if you complain about this to their support things actually seem to get fixed? That was kind of a shocker, I'd suggest sending them a note if you have issues. Though this particular IMAP transfer between accounts has worked between my other email accounts (exchange and some linux server long ago) and gmail since I first tried it so it's a little sad. But a smaller team I guess? But paying for it so... Mixed feelings for sure.

    I’m not exactly sure, I didn’t identify a clear pattern. One thing I noticed is that emails with French or German accents/umlauts in their subject line fail to be imported. But others don’t have that characteristic.

    I can't remember now, and there is a chance that it was the emails that were problematic. The behaviour of the import/export tool was just unforgivable though. It wouldn't handle the emails it couldn't import gracefully it would just hard fail.

  You could try a third party bridge: https://github.com/emersion/hydroxide https://github.com/emersion/hydroxide

  We have been working on improving the Import/Export tool, and have deployed some fixes and improvements requested by users. For example, we've: - Increased the number of supported mail providers by changing the way folder structures are handled - Improved the handling for unstable internet and pause/resume behavior - Fixed the rare cases where the application freezes when starting/stopping imports - Improved the manual update process The Import/Export tool will be exiting Beta with these improvements this month. If you try the production version, we're optimistic it'll work a lot better.

I stand corrected on this.
