What you get
01AI-targeted lists. Home age, permit history, system age, and property data identify homes most likely to need replacement in the next 6 months.
02Personalized postcards. AI generates copy and design for each neighborhood, referencing local rebates, system age, and replacement urgency.
03Trigger-based timing. Mail goes out when system signals fire: heat events, permit data updates, or seasonal stress patterns.
04AI receptionist + call tracking. Every campaign gets a unique tracking number. PingMunk's AI receptionist answers 24/7, captures lead details and call transcripts, and sends them to your team in real time.
05Real-time dashboard. Photo proof of every mail piece. Full call recordings and transcripts. Direct attribution from postcard to inbound call.
"But your cost per piece is higher."
True. And that's the point.
Mail Shark and PostcardMania charge per piece because more pieces means more revenue for them, even when those pieces hit homes without HVAC. Their incentive is volume. Yours is booked jobs. PingMunk charges flat monthly so we make the same whether we mail 1,000 or 5,000 pieces. Our only incentive is sending fewer, smarter pieces that produce calls.

Our promises
Four things you won't get from Mail Shark, PostcardMania, or Cactus.
Cancel anytime, processed in 24 hours. No locked contracts. No hidden auto-renewals. Refunds for any unsent mail.
Flat monthly pricing, no per-piece games. We don't make more by mailing more. Our incentive matches yours: book replacement jobs.
Everything included. Design, lists, printing, postage, AI receptionist, call tracking, dashboard. No setup fees, no surprise charges.
Smart de-duplication. If we work with multiple HVAC contractors in your metro, no household ever receives mail from two of our clients in the same month. Your campaigns never look like spam.
