This is the company that invented the term dogfooding and forced everyone to use Exchange until all the bugs were worked out.
I’m building a next gen web mail app at work and there are a ton of UX edge cases but the performance of the core UI is not rocket science.
I’m looking for help play testing to squash bugs, improve the last mile of performance, and to add Outlook support.
The incentive is the mail app is “malleable” so you can craft custom workflows and UI widgets to help you get to inbox zero.
