A short label for the offering: how long it lasts, that it is one-to-one, and who it is for.
Name of the mentorship
One sentence. Say the roster is full, then ask them to join the waitlist so they hear when a spot opens. This is the line that does the asking — keep it to a single sentence.
Two or three sentences on the work itself. The goal of this paragraph is to help someone decide whether this mentorship is for them: who you sit with, what a session is like, and what changes if they stay. Do not repeat the waitlist ask here.
