Why don't I see my campaigns in the Salesforce integration?
Please make sure your connected integration user has "Marketing User" rights. If you have connected the Salesforce integration, it's important to ensure that the connected user has Marketing User rights in Salesforce. Otherwise, when you are trying to use our Salesforce integration mapping rules, you may notice Campaign is not selectable as an entity on the Salesforce side of mapping rules.
If you notice this, please review your Salesforce user account and make sure the user has the Marketing User rights enabled as this is required to gain access to Salesforce campaigns.
