We have a current onboarding campaign that triggers when a SFDC opportunity closes (using Opportunity is Updated trigger with trigger attribute: Entitled Issued field becomes True and previous value is False). This triggers all contacts under that opportunity to receive a series of emails that onboard them as new customers. Our goal is to onboard all contacts under the account, not just under that opportunity, when an opp closes. Is this possible? I don't see a trigger that looks for account changes, and the Opportunity is Updated trigger won't look for other account contacts that aren't under that opp, will it? Thanks for any advice.
