The Math Behind Window & Door Replacement Postcards

Say you have 1,000 homes to reach. Here's what a PostKnock campaign looks like:

  • 1,000 postcards × 3 waves = 3,000 cards × $0.79/card (Pro) = $2,370 total spend
  • At a 2% response rate → 20 in-home estimates
  • At a 15% close rate → 3 booked jobs at $8,000 (average project)
  • 3 × $8,000 = $24,000 in new business

That's a 10:1 return on a $2,370 investment.

Frequently Asked Questions

How much do window & door replacement postcards cost?▼

PostKnock postcards start at $1.05 per 4x6 card on the Free plan and drop to $0.79 on Pro. No setup fees, no minimums, no contracts — you only pay for what you send.

What should I put on a postcard for window, door, and siding replacement companies?▼

The most effective cards lead with a clear offer ($1,000 Off Any Full Window Project), your business name and phone number, and a QR code to book online. PostKnock templates include all of these with smart fields that auto-fill each recipient's name.

Does direct mail beat email for this?▼

Yes — direct mail gets far higher response than email (postcards have a 100% open rate, no inbox to ignore). Adding a phone follow-up call after delivery lifts response further, which is exactly what PostKnock automates.

How fast can I launch?▼

About 30 minutes from signup: upload your customer list as a CSV, pick the pre-built playbook, customize the offer, and click Launch. Postcards mail via USPS First-Class within 1–2 business days.

Can I cancel anytime?▼

Yes. Pro is $99/mo (or $799/yr). Cancel anytime from Settings → Billing; you keep Pro features until the period ends, then revert to Free. No contracts or cancellation fees. Annual plans include a 30-day money-back guarantee.

Why use postcards plus calls for window, door, and siding replacement companies?▼

A single touch rarely converts. PostKnock runs a 3-wave sequence — a postcard, then a follow-up call after delivery, then another wave for non-responders — so homes who ignore the first touch still get reached.
