Can I chain together several campaigns?

No. Currently, campaigns cannot be chained together. 

We do have other options to make your contact follow-up strategy easy and seamless. 
Within each campaign template, you can add to the sequence to extend the length of the campaign.
You can also move contacts into a new campaign OR schedule an individual followup for a later date.

We also have an auto-nurture feature, which can be accessed by clicking the Auto-Nurture tab in the main menu. Note: Auto Nurture is only available with our Premium Subscription.
