(2) Boomerang

With Boomerang, you can write an email and schedule it to be sent automatically at a specific time later. Just write the messages as you normally would, then click the Send Later button.

There are times you need to make sure you follow up within a specific time frame after sending a message. You can select to only be reminded if nobody replies, or regardless. This way you won't let messages slip through the crack and will never forget to follow up with people.

By using Boomerang you remove messages from the inbox until you actually need them. You just need to click the Boomerang button when the email is open, and choose when it is needed again.
