You get one list each morning with everything that’s still open. And if you manage people, you can see what the whole team is waiting on.
FollowUpThen is a flexible personal reminder service where you choose a time in the email address. Loop is built around waiting on other people: every ask gets a due date automatically, closes when they reply, and shows up in a single morning digest and a team view.
