Most pool businesses neglect email and SMS to existing customers. Done well, this is your highest-margin marketing channel, you already have permission, you already have the relationship.
Use cases that work.
- Service-day texts: automated "Your pool tech will arrive between 10–2 today." Reduces customer-not-home headaches by 80%+.
- Post-service report: chemistry results + pool photo. Standard in modern routing apps.
- Seasonal communications: "Open your pool" reminder in spring; freeze warning in winter; algae bloom alert during heatwave.
- Maintenance reminders: salt cell cleaning, filter media replacement, heater service.
- Birthday / anniversary messages: for 5+ year customers, a quick handwritten card or a $25 service credit on their service-anniversary year.
Upsell motions.
- Annual filter cleaning at a flat fee ($75–$150)
- Salt cell replacement when nearing end of life
- Seasonal equipment inspections ($50–$100)
- Vacation watch (extra service days at premium pricing)
These typically add 5–15% to revenue per account from the same customer base, with near-zero CAC.
Frequency rules.
- Operational texts (service-day, post-service): every visit, expected
- Seasonal alerts: as needed, 4–8 per year
- Educational / nurture: monthly is plenty; weekly is too much for service customers
- Promotional: rare, only for genuine offers (e.g., "we've added repair service")
Compliance.
- Get explicit consent at signup (most CRMs handle this)
- Honor opt-outs immediately (TCPA fines for SMS violations are $500–$1,500 per message)
- Never share lists with anyone
- Use a TCPA-compliant SMS platform, not your personal phone
