Direct Mail Postcard Strategy Review — Solar Panel & E-Waste Recycling (B2B)

I’m launching a direct mail postcard campaign targeting solar installation companies to promote our solar panel and inverter recycling services. I’ve run a successful cold call program targeting this same audience, and I’ve drafted an initial postcard concept. I’m looking for an experienced direct mail consultant to review my plan — not write copy from scratch. Specifically, I want feedback on: * Whether my offer/CTA structure is likely to perform, based on real B2B direct mail response-rate benchmarks * Gaps or weaknesses in my targeting, format, or messaging approach * Best practices for tracking response (phone line vs. QR code vs. unique URL) for a first test batch * Any changes you’d recommend before I move to print/mail Deliverable: a written list of recommended changes, plus a short call to walk through them. Scope: This is a single strategy review, not an ongoing engagement or a copywriting job. Flat-fee proposals preferred over hourly. Ideal candidate: Direct mail experience in B2B recycling, sustainability, or waste/materials services — someone who understands niche commercial service providers, not just consumer retail. Real response-rate data to back up recommendations is a plus.
