What is the plan to make money off this? Sell what you read in my emails? Charge me a monthly fee at some point? Also my initial reaction was that I wasn't aware that composing an email is slow.
It definitely isn't slow for all users! However, there are some that send so many emails that any incremental speed-up is very helpful. Plus, we're looking to start working on mobile, where it should be most useful!
If that's the case, that's a fascinating insight - thank you so much for sharing it!
