YOUR AD LANDS IN
REAL MAILBOXES.
NOT SPAM FOLDERS.
98% of people check their physical mail every single day. Unlike digital ads that get scrolled past or blocked, a giant 9×12 postcard physically demands attention the moment it hits the mailbox.
It's tangible. It's oversized. It's impossible to ignore — and it carries your brand directly into the homes of 5,000 Castle Rock families.
Physical mail is seen, not filtered
No pop-up blockers or ad fatigue
Reaches every household, guaranteed
WHY STANDARD MAIL IS IGNORED
Over 90% of standard 4×6 postcards are thrown away before they are even read. They slip between magazines, get buried under bills, and blend perfectly into the 'junk mail' stack.
- Lost in the shuffle: Standard sizes are physically hidden by larger mail.
- Wasted budget: You pay full postage for mail that goes straight to the trash.
- Zero authority: Flimsy cardstock communicates a cheap brand image.

Frequently Asked Questions
Everything you need to know about advertising with My Giant Postcard in Castle Rock.
Will my competitors be on the card?
No. We offer strict category exclusivity. Once you lock in your territory and ad block, no other business in your industry can advertise on that same mailer. Your message stands alone.
How do I know it was actually mailed?
Total transparency. We provide official USPS Postal Receipts and tracking documentation the moment your campaign hits the mail stream. You’ll know exactly when homes in your zone receive the card.
Who handles the design of my ad?
Our expert design team handles everything. We custom-build your ad block to maximize response rates at no extra design cost. You just approve the final proof.
Do I have to commit to multiple mailings?
No. You can start with a single 1X drop to test the response. We also offer significant discounts for 4X and 12X campaigns to build consistent local frequency.
How does shared direct mail advertising work?
Multiple local businesses share space on a single oversized 9×12″ postcard. We handle design, printing, and mailing — you claim your slot, provide your content, and we do the rest.
How many homes will see my ad?
Each mailing reaches 5,000 households across Castle Rock, Colorado — targeted, high-income residential neighborhoods where homeowners are actively seeking local services.
Can I design my own ad?
Absolutely. You can provide your own design, or we can help create a professional ad that fits your slot size. We want your ad to look great and drive real results.
How often are postcards mailed?
We mail on a regular schedule — typically monthly. Once all slots are filled we finalize the design and send to print. You’ll receive confirmation of your mailing date once your spot is reserved.
What kind of businesses advertise?
Any local business serving homeowners is a great fit — HVAC, plumbing, roofing, landscaping, restaurants, salons, dental offices, real estate agents, gyms, pet services, and more.
Is there a contract?
No long-term contracts. You reserve a spot for a single mailing, and if you love the results you can renew for the next one. We believe in earning your business every single time.
What kind of return can I expect on my investment?
The math is straightforward. A 5,000-piece drop at a conservative 1.5% response rate generates roughly 150 inquiries. If your business closes 30% of those, that’s about 45 new customers from a single mailing. For a home services business averaging $350 per job, that’s over $15,000 in new revenue from one postcard. Most advertisers see a strong return within the first mailing and renew immediately. Results vary by offer, business type, and follow-up, but the fundamentals of direct mail are predictable in a way that digital advertising simply is not.
Built by a Castle Rock
Business Founder
Hi, I'm Graylan Stewart, a Castle Rock local and the founder of My Giant Postcard. Like you, I know firsthand what it feels like to pour everything into a business and wonder if the right people are even seeing it. I launched My Giant Postcard because I believed there had to be a smarter, more connected way for local businesses to grow together.
The idea is simple: when local businesses support each other, the whole community wins. Instead of competing for attention on crowded social feeds, we pool our resources and show up together, right at the front doors of the Castle Rock families we all serve. One beautiful mailer. Multiple great businesses. Real neighbors, real results.
This isn't just advertising. It's community. And I'd love for your business to be part of it.
And here's what gives our advertisers real confidence: this isn't my first rodeo. I've been in the postcard and magazine advertising space for local businesses since 2003, working with thousands of business owners across the country. I bring that deep industry knowledge directly to every mailer we produce right here in Castle Rock. You're not just getting a neighborhood idea. You're getting over two decades of proven direct mail expertise behind every campaign.
