WhatsApp templates that actually convert
The 6 templates we A/B-tested with 50,000 gym members. The winners aren't what you think.
Last quarter we ran a controlled test of 6 different WhatsApp templates across 50,000 members from 28 gyms. The goal: figure out which messages actually drive renewals, and which ones just feel busy.
Setup
Each member was randomly assigned to one of six template variants 10 days before their renewal date. We measured response rate, renewal rate, and unsubscribe rate. We also measured perceived friendliness via a follow-up survey.
What won
- Personal salutation > generic greeting (12% lift)
- Specific recent activity reference > general account info (18% lift)
- Question format > statement format (9% lift)
- Single CTA > multiple options (24% lift)
- First-person from a real human > 'Team Kasratbook' (31% lift)
- Sent at 11 AM > sent at 7 AM or 9 PM (8% lift)
What lost
Emoji density beyond 1-2 per message reduced renewal by 6%. Time-pressure language ("only 24 hours left!") reduced renewal by 14%. Discount-led copy reduced renewal by 11% — surprising us, until we realized the framing was making members feel like the gym was desperate.
The winning template
"Hi Rohan, this is Priya from Iron Club. I noticed you've been crushing it in the morning slot — 14 sessions this month. Your membership renews on April 30. Want me to send you the link?"
It's specific, it's personal, it acknowledges effort, it has one CTA, and it sounds like a human wrote it. Renewal rate on this variant: 78%. The control variant: 53%.
