I like Right Inbox because of its snooze functionality, and it integrates directly with Inbox by Gmail. Right Inbox lets you send, schedule, or snooze emails. You can classify emails with labels and prioritize them. It’s very customizable.

Right Inbox was cheap, and very handy with my email philosophy. It basically adds a "send later" button to your Gmail. I think we're all pretty healthy in our work habits, but if we happen to be working at a time that doesn't make sense to our client or team, we can just use the “send later” button and it automatically sends it in the morning. I used it more for the reminders when I was handling clients first hand, but my staff handles most of that now.
