How it works
One campaign.
Each step connected.
Your prospect list builds itself, too.
Saving routes finds and ranks local businesses, with available contact details and reasons to call. Work your first 50 leads free. You make the outreach; the workspace keeps your notes and follow-ups together.
A yes becomes a spot on the card.
Choose a paid plan, connect Stripe and publish. Advertisers choose a spot and pay online. The payment, buyer and placement stay together automatically.
The spot sells.
The busywork shrinks.
Payment. Recorded.
The spot is marked sold, with the buyer and payment attached automatically.
Details. Collected.
A private link lets your advertiser submit their business details and offer. No account to create.
Proof. Approved.
You prepare the ad. They approve it or request changes. You see what’s ready for print.
Explore the advertiser’s side of a campaign. No signup, charges or messages. Opens in a new tab.
The operator behind the software
I run cards, too.
I’m Dustin. I run community postcard campaigns under the SpotDrops name, and I build and support 9x12 Tools.
The original version put the website first. Working with operators taught me to focus on finding businesses, following up and collecting payments. That’s the work I’m building this to help with.
More about me and my cards Have a question? Ask me.A few things before you start.
What can I do for free?
Build your card, choose USPS routes, set spot prices and preview your campaign website. Your prospect list generates automatically, and you can work your first 50 leads free. No credit card required.
When do I need a paid plan?
When you’re ready to publish and take payments. A plan unlocks your domain, advertiser checkout and reservations. Paid prospect discovery continues as you work. Connect Stripe to collect advertiser payments. Plans start at $97/month; printing, postage and Stripe processing fees are separate.
Can I bring a card I’m already selling?
Yes. Recreate your layout and record paid spots as Sold offline, including payments collected elsewhere. Advertisers keep their placements without being charged again and receive a private workspace link. Choose a plan to publish and sell the remaining spots.
Does it sell the spots or mail the card for me?
You contact advertisers and make the sale. The platform finds prospects, drafts outreach and tracks follow-ups. You prepare the artwork, collect approvals here, then export for your own printer. Printing and mailing stay with the providers you choose.
