Sharing with you two different ways on how to add contacts to a campaign in Agentgogo CRM: 


  1. On the Contacts tab (from the navigation button) > go to the campaign on the right side, hit the plus button, and then find the campaign you're looking for.
  2. Another way is by adding contacts in bulk; you may either do one at a time or check the "select" box, then add people. Once done, add people to the campaign.
