Pick your industry and a design, and we'll print and mail one to your address. No credit card. In your hands in about a week.
No account needed · One real postcard · Yours to keep
Three quick steps. No software to learn, no card to enter.
Choose the vertical that fits you and a postcard style. These are the same professionally designed templates our customers send.
Tell us where to send it. No credit card, no signup — just a name and a mailing address so USPS can deliver it.
We print it and hand it to USPS within a few days. It lands in your mailbox in about a week — and it's yours to keep.
The best way to judge a postcard is to hold one. So before you commit to anything, see the actual print quality in your own hands.
This isn't a PDF mockup. It's a real printed postcard on real card stock, mailed via USPS First-Class — exactly what your customers would receive.
Check the colors, the paper, the finish. No risk, no card on file, no obligation to send a campaign or upgrade.
PostKnock is built for small service businesses that want direct mail without the agency price tag — a straightforward alternative to tools like Postalytics. See the comparison →
One per address, please. Each sample is a real printed postcard with real postage, so we send one per mailing address. If you like what you get, the next step is a free account — no credit card to start, and you only pay per card when you're ready to send your own campaign.
Pick a design, enter your address, and we'll do the rest. No credit card required.
