We're relatively new to Zoho and I'm trying to determine the best route when it comes to Contacts/Leads who unsubscribe. I was told about the unsubscribe form for the CRM but the Zoho representative wasn't sure about what that would do in MarketingHub, if anything. I would like to keep track of all Leads/Contacts, even if they unsubscribe, to keep from re-adding them in the future and sending them mail again by accident. Anyone aware of a place where such Leads/Contacts can be stored to avoid sending them emails from the CRM or MarketingHub? Thanks!
