When you’re selling boarding, lessons, or training, (and if you’re not selling, why aren’t you?) ask for the prospect’s email address.
Simply say at that end of your conversation, “Would it be OK if I emailed you more information about our program?” 99% of the time the prospect will say yes.
Then follow up with more information and your contact information. Serious buyers don’t mind being “sold” with more information to help their buying decision.
