You can add a Meeting Scheduler link to campaigns built on Gmail or Outlook.

To use your Meeting Scheduler Link in a Campaign, find the "Meeting Link" button at the bottom of the compose area for your email touch. You can then choose if you'd like to use your general calendar link or a Custom Meeting Type. Once you select which you'd like to insert, it will add the meeting link to your Campaign Touch content, streamlining meeting booking workflows. 

Once a recipient books a meeting, they will be removed from the Campaign, as this counts as a "connection" (if you've kept the default setting to remove recipients after connection).
