This is the fastest way to build an agent that handles leads in your inbox: > go to sim.ai > type in this prompt > "Watch my inbox for new leads: classify each one, draft a personalized reply I can send, and post a heads-up in # sales with the category" > once a lead emails > an agent now reads it, figures out what they want, drafts a personalized reply > logs in your CRM and pings your team in Slack
