First, don't use REI Reply, it's just a white-labelled/private-agency version of GoHighLevel (the actual provider of the CRM) that they just mark up and charge you extra for everything you do (every text, email, etc is 2-10x more expensive than just linking twilio/mailgun to your GHL account, etc).With that out of the way, you can get to making workflows.
