Mail Shark is one of the most HVAC-aligned direct mail vendors on the market, with an entire vertical practice built around heating, cooling, plumbing, and electrical contractors. Their flagship RRN Program bundles three proven home services mail plays: Radius mailings that target neighbors of recent installs, Retention mailings to current customers, and New Homeowner mailings.
Everything is produced in-house at their Mohnton, PA facility, which includes an on-site USPS office for faster drop times. Mail Shark's mailers include postcard magnets (fridge-stick), plastic mailers, scratch-offs, rebate-check lookalikes, and oversized postcards. Saturation mailings can hit 15.5¢ postage per piece.
Mail Shark is ideal for HVAC contractors who want a real strategist, oversized or specialty formats, and tight integration between recent-install address lists and radius drops.
