Rather than sending an email in a campaign, you have the option to create a Task to remind you to send the email. 

You choose when subsequent emails go out , and can personalize each one before they're sent. Access this task right from your inbox in Gmail and Outlook, and in your Live Feed in our web application. To have your email queued up as an email task, just check the email task option.

When you select this option, the email will show up in your Task bar in the Command Center.

If you click Email, it will pop out the Template you selected in the Campaign to send to the contact (we will also complete your task so your Campaign moves forward).
