The PostKnock Postcard Designer lets you experiment with a real postcard layout in your browser. Pick one of the nine pre-set industries to load themed colors, copy, and a stock photo — or start from scratch with the Custom option. Switch between four design styles (Bold, Photo, Minimal, Gradient) to see your message in different visual treatments.
Every input updates the preview instantly. Headline, offer, business name, call-to-action, and the two brand colors all flow into the postcard layout the same way they do inside the PostKnock app. The four styles are the same shells we use to render real postcards mailed via USPS — so what you see is what your customers would actually receive.
When you're ready to send, the "Use this design with PostKnock" button takes you to signup. Inside the app you'll upload your contact list, pick a campaign playbook (with timing, follow-up calls, and tracking already configured), and the postcards drop in the mail within 1–2 business days.

No. The designer runs entirely in your browser and is free to use without an account. You only need to sign up if you want to actually mail the postcard via PostKnock.
Yes. Click "Save as image" to download a PNG of your postcard front. Note the downloaded image is preview quality — production postcards are rendered at 300 DPI inside PostKnock for crisp printing on USPS stock.
PostKnock supports 4×6, 6×9, and 6×11 inch postcards. The designer previews the 4×6 (the most popular size and the cheapest to mail at $0.79/card on the Pro plan).
Canva and Photoshop are general design tools — they give you a blank canvas and full control. The PostKnock Designer is the opposite: every layout is engineered to print cleanly at USPS bleed/safe-zone specs, with QR codes, addressing, and personalization tokens already wired in. Pick a style, type your offer, and you're done. No DPI math, no bleed setup, no print files to upload.
