I agree with this. From the perspective of the coach, I don’t really understand it. Even if you ignore the fact, that it would be good to actually know what works, writing an email to a client a year afterwards asking: “We had our coaching a year ago, and I’m curious about whether the effects lasted?” is useful purely from a marketing perspective. If the person answers “Yes”, the coach just reminded them that the coach successfully helped them with a problem that they have in the past which makes it more likely that they will come back as a client and book another coaching session or recommend the coach to other people.
