We run a brokerage shop and do not use a CRM (comment on that later). All fresh leads come direct to our site via online marketing campaigns. I am trying to find a round-robin type of e-mail system for Gmail that will evenly distribute these leads to our sales reps on a particular schedule so that they can all work on these exclusively for a given period of time and then shift them around. How can this be done via e-mail without a CRM? I am in talks to develop a software for this if there's interest lmk.
