Drip campaigns need to gave the ability to filter out product sales only clients (clients that visited x number of days ago and purchased products as opposed to clients that had a service) and they also need to be able to filter out clients that have already rebooked and have a future appt on the books. We want to send a series of nurturing e mails/texts, but it would be annoying for clients to receive them if they had already rebooked their next appt. And if we want to include an offer it would irritate a client that they didn't get that offer (or it would just train them to not book and just wait for an offer)
