Take control of when you send and receive email messages with the Boomerang plug-in for Gmail . This app absolutely lives up to the reputation of the Australian tool it's named after, allowing you to - hypothetically - throw emails out of your inbox when you want and, in this case, have them come back in when you schedule them to reappear.

Write an email now and schedule it to be sent, automatically, at the perfect time. Clean up your inbox by asking Boomerang to remove certain emails and bring them back when you actually need them.

Plus, say you need to make sure you follow up with a client within a specific time frame after sending a message. You can ask to be reminded so you'll never forget to follow up with people again. Another alternative is to avoid email altogether and use SavvyDox to track due dates on your tasks and use SavvyDox to determine if your recipients have completed their review by the designated time and even understand how many pages of the document that they have read.
