This is why I believe that email funnels are the way to run out of spots for new clients:
Email funnels, at least the ones I made, always start with a strong lead magnet. This leads a large number of people to sign up for the email list and go through a welcome sequence with a tested strategy. Leading to a bunch of automated inbound leads and booked calls. Then they will start receiving newsletter emails which will convert the rest of the potential clients in the list. A big wave of new subs will get on the list 1-2 times per month with every new lead magnet. And they’ll go through a 90% similar repurposed welcome sequence to save time while getting the same results.
