I'd like to create an automation rule to remind our customers that we're waiting for their response. Ideally the rule would execute once after 3 days of no response then again after 6 days of no response and then close itself after 10 days and notify the customer. I could do this in Zendesk without problem. I've fiddled with workflows in Zoho but I don't see any options that would enable the capability that I'm looking for. Thoughts?
