Seasonal maintenance postcards land right before peak demand. Then PostKnock tells your team exactly who to call and what to say—so you book jobs before the rush.
Start Free — No Credit CardHVAC is moment-of-need. Your past customers won't think about maintenance until something breaks. A well-timed postcard + call right before the season hits converts because you're solving a problem they haven't thought about yet.
Three campaign types. All pre-configured with timing, scripts, and postcard copy direction.
Seasonal urgency. Tune-up special + priority scheduling offer. Deploy late Feb/Mar for AC; late Sep/Oct for heating.
"We're booking up fast, want to lock in your spot?" Second postcard only if no contact.
Equipment age + failure risk framing. "Your system was serviced in 2022—units over 3 years without maintenance have significantly higher failure rates." Priority scheduling offer.
"We noticed it's been a while since we serviced your unit. Want to get ahead of any issues before the season hits?" Pre-loaded script with equipment history notes.
Different design with cost-of-breakdown framing. "Emergency repairs average $1,200—a tune-up is $89." Final call attempt for non-responders.
"Last chance before peak season" urgency. Limited-time discount. Non-responders rest 90 days, then recycle next season.
HVAC is moment-of-need—timing beats volume. Lists recycle spring + fall.
Choose "Spring Maintenance," "Fall Maintenance," or "Win-Back Campaign." Timing, scripts, and postcard direction are pre-configured.
Export past service customers from your CRM as CSV. Include last service date and equipment type for targeted messaging.
Postcards mail via USPS. Your call queue populates a few days after delivery. Time it right and customers book before the rush.
Pre-loaded scripts. Log outcomes. Warm leads get priority. The sequence runs itself, Mon–Sat.
