We looked at renewal payment timing across the gyms running on GymProHub. The pattern is clear.
The baseline: no reminders
Gyms that don't send any renewal reminder collect 62% of renewals on-time (within 3 days of expiry). 38% are late or missed entirely.
Email-only reminders (7 days out)
Adding a single email reminder 7 days before expiry bumped on-time renewals to 74%. Better, but Nigerian gym members open email at ~30% within 24 hours.
Email + SMS 7 days out
Adding an SMS at the 7-day mark took on-time to 83%. SMS delivery rate is 95%+, open rate near 100% within 3 minutes.
Email + SMS with follow-up 1 day out
Adding a second SMS at 1 day out took on-time to 92%. Late payments cut by more than half.
