You can use GetFeedback for Salesforce integration to add Campaign Members to your marketing Campaigns as well.
From your survey in app.getfeedback.com, select Mappings > Salesforce Custom Mappings to map your survey to Salesforce. Use the following mappings:
After creating your mappings, format your survey link to include merge fields for your campaign ID and the contact, lead, or account ID you want to add as a campaign member. These merge fields tell us who to add to the campaign and which campaign we're adding them to. Learn how to add merge fields to your survey link.
Your formatted survey link may look like the sample link below:
The merge fields in the survey link pull in the appropriate Contact ID and Campaign ID when you send the survey from Salesforce. When a recipient takes your survey using the formatted link, we’ll map their information back to Salesforce to create a new campaign member.
