Hi,
in order to sync Marketo with Salesforce, we are using the Salesforce license of an existing user (and not a dedicated user how is recommended). This user is not so active in Salesforce, that's why we decide to use his license. However the user needs to have access to a custom object (email messages from gmail attached to each lead by MatchMyEmail app). If we set this object to be visible from "custom objects permission set" section of the profile, the object (and its fields: mail subject, body, recipeint etc.) will sync with Marketo. Would this be an issue for Marketo? I mean if it wont overload the system or any other issues.
Thanks,
