Filter all contacts of accounts with opportunities
Our Team has been struggling since quite sometime now to filter out leads, contacts of accounts that has opportunity (SFDC) above certain stage. We would want to avoid sending emails to these contacts who are already engaged with active opportunities. I do understand that we can filter out contacts that are associated with opportunities but we do not normally have all contacts associated with the opportunity.
Is there any possible work around to filter out contacts from sending emails who has opportunities.
