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.

Everything you need to know about advertising with My Giant Postcard in Castle Rock.
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.
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.
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.
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.
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.
Each mailing reaches 5,000 households across Castle Rock, Colorado — targeted, high-income residential neighborhoods where homeowners are actively seeking local services.
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.
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.
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.
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.
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.
Hi, I'm Graylan Stewart. I've called Castle Rock home since 2013 and have spent years helping local businesses connect with local families throughout our community.
Long before launching My Giant Postcard, I published Local Ad Mag in Castle Rock for nearly seven years, helping hundreds of local businesses generate leads and grow through direct mail advertising.
That's why I'm excited to bring My Giant Postcard to Castle Rock. Instead of fighting for attention online, or getting lost in a newspaper or magazine filled with competing ads, local businesses join forces on one oversized postcard that is delivered directly to thousands of Castle Rock mailboxes.
And while Castle Rock is home, my experience extends far beyond Douglas County. Since 2003, I've helped thousands of business owners across the country generate leads through direct mail, postcards, digital marketing, and more recently, AI-powered automation systems that help businesses capture, follow up with, and convert more leads.
My Giant Postcard combines local relationships with more than 20 years of proven marketing experience, helping Castle Rock businesses stand out, generate leads, and grow. I'd love for your business to be part of it.
Strictly limited to ONE business per industry per mailer. Don't let your competitor steal your spot.
