ThunderBet had a 200K+ player database but was only sending weekly generic newsletters with a 12% open rate. Massive revenue was left on the table from unengaged and lapsed bettors. We implemented a full lifecycle email and SMS program with 18 automated flows, behavioral triggers, and dynamic content personalization.
ThunderBet Sportsbook had 200K+ registered players and a solid acquisition engine — but their CRM was almost non-existent. The marketing team sent one generic newsletter per week to the entire database. Open rates had declined to 12%, click-through was under 2%, and the unsubscribe rate was climbing. A massive segment of the database — 60K+ players who hadn't deposited in 90+ days — received the same content as daily active bettors. The estimated revenue left on the table from poor retention marketing was $350K+/month based on industry benchmarks for operators of similar size.
We built a complete lifecycle email and SMS program over 8 weeks. Week 1-2: integrated ThunderBet's database with a modern ESP, configured event tracking for 20+ behavioral triggers, and built 15 dynamic segments (new, active, VIP, at-risk, lapsed by 30/60/90 days, sport preference, deposit frequency). Week 3-5: designed and launched 18 automated flows — welcome series (5 emails + 2 SMS over 14 days), pre-match reminders based on favorite teams, deposit encouragement after login-without-deposit, bonus expiry alerts, milestone rewards (10th/50th/100th bet), VIP tier upgrade notifications, and a 6-step win-back sequence for lapsed players. Each email used dynamic content blocks adapting to the player's sport preferences, betting history, and segment. Week 6-8: launched SMS campaigns for high-urgency triggers (live match cash-out reminders, limited-time odds boosts) and implemented send-time optimization based on individual engagement patterns. Results: email open rates jumped to 34%, SMS click rate hit 18%, 15K lapsed players were reactivated in the first quarter, deposit frequency increased 45% among players in automated flows, and the program generated an additional $280K/month in attributable revenue.
