Notice attendance, not just expiry
A paid membership can still hide falling engagement. Compare attendance with the member’s own routine and check whether a pause or schedule change explains the gap.
Offer support
Ask whether a different session time or a trainer check-in would help. Avoid judgment about bodies, fitness or motivation. Keep the response optional.
Keep renewal separate
An attendance check-in and a payment reminder solve different problems. Use clear eligibility and timing, and avoid sending both together unnecessarily.
Measure the return to habit
Track attended sessions after the check-in, not just replies. Look at repeat attendance in a defined period and count the cost of any included benefit.
