With HEY, if you know you need to reply to something later, just tap the “Reply Later” button to move the email to a dedicated ‘Reply Later’ stack at the bottom of the screen. It sticks around, but stays out of your way. Queue ‘em up throughout the day.
Then, when you do have the time, click the ‘Focus & Reply’ button. This lines up every email in your Reply Later stack, all open on a single page, one after another, with a reply box next to each one. Now you can knock them all out without being distracted by anything else. It feels like magic, and there’s absolutely nothing else like it.
