TestFlight

Before you jump in, please take a moment to read the following information carefully. It's really quite important.

This is an early pre-release build of Big Mail, and as such some features may not work as intended or at all. You'll also find there's a lack of "fit and finish" across the app. Always check the known issues before installing.
To help us troubleshoot any issues you may have, pre-release builds have increased logging. This increased logging has some impact on performance.
Debug logs stay on your device until you explicitly share them with us in Settings. All shared logs get destroyed after 24 hours.
Whilst we don’t mind you Tooting or Tweeting your Big Mail experience, we’d kindly ask you hold off reviewing it until we have a final release.
Due to different encryption keys between our development and production systems, we’ll be unable to transfer your Big Mail data over to the App Store release. We may also periodically ask you to reset and reinstall Big Mail from factory settings.
Whilst every effort has been made to squash serious bugs, pre-release builds do not go through our usual QA process, and as such data loss is a possibility. If that makes you uncomfortable, we’d suggest waiting for the App Store release.
We really want to hear what you think! Join us over at The Email Emporium to discuss new features and ideas. We're also tracking bugs there. And of course you can always just email us [email protected] if you prefer.

If you're happy and that all makes sense, then proceed below.
