How It Works

From sign-up to first postcard sent in under 30 minutes.

1

Pick a Playbook

Choose a pre-built campaign template or start from scratch. Wave count, timing, call scripts, and postcard copy are pre-configured.

2

Import Your List

Upload a CSV of your target contacts. Our field mapper auto-detects columns and lets you preview before importing.

3

Launch the Campaign

Review your settings and hit launch. The platform mails postcards via USPS, then populates your front-desk call queue a few days later.

4

Work the Call Queue

Your front-desk staff see a prioritized call list with pre-loaded scripts. Log outcomes, and non-responders automatically roll to the next wave.

The Only Platform That Turns Your Front Desk Into a Follow-Up Machine

Other tools send postcards and hope for the best. PostKnock sends postcards and tells your staff exactly who to call, when, and what to say.

☎

Systematic Callback Queue

After postcards land, your staff sees a prioritized call list with scripts, talking points, and outcome tracking. Home services customers average 5.5 touchpoints before converting1—PostKnock makes sure they happen.

★

Postcard → Call → Postcard → Call

Coordinated waves where each postcard warms the prospect and each callback moves them closer to booking. Non-responders automatically advance to the next touch.

✉

Real USPS Postcards That Get Opened

Direct mail averages a 4.4% response rate2—and response hits 5–9% on house lists. When your staff calls, the prospect already knows who you are. The postcard warms the lead so the callback isn't cold.

Frequently Asked Questions

How much do postcards cost to send?▼

PostKnock postcards start at $1.05 per 4x6 card on the Free plan (includes printing + USPS First-Class postage). Pro plan drops it to $0.79/card. Larger sizes (6x9, 6x11) are available. No setup fees, no minimums, no contracts.

What is postcard marketing with follow-up calls?▼

PostKnock combines direct mail postcards with automated phone follow-up. You send a postcard, and a few days after delivery, your team gets a call queue with the right script for each contact. The postcard gets attention, the callback closes the deal.

What industries does PostKnock support?▼

PostKnock has ready-made campaign playbooks for healthcare-style practices (dental, optometry, chiropractic, med spas, veterinary clinics) and home-services contractors (HVAC, plumbing, pest control, landscaping). But it works for any local service business.

How does PostKnock compare to other direct mail tools?▼

Most direct mail tools only send postcards. PostKnock adds phone follow-up calls, industry-specific playbooks, and a built-in call queue. See how we compare to Postalytics and PostcardMania.
