Partnership Proposal: The "SlowPostBox" Campaign
March 13, 2026
To: Coffee Shop Owners & Managers
Turn Your Coffee Shop into a Destination for Memories
The SlowPostBox event is not just "extra work"—it is a powerful branding tool designed to encourage customers to stay longer and return more often. We invite you to become a campaign partner and add the "Value of Waiting" to your aromatic space.
In a world that moves too fast, help your customers pause. Let them write a heartfelt letter to their loved ones or their future selves, delivering the excitement of a message that arrives one year later.
Why the "Slow Post Box"?
Beyond just serving coffee, your cafe will be remembered as a place where memories are recorded and cherished. This naturally leads to:
Increased Dwell Time: Customers stay longer to decorate and write their letters.
Enhanced Brand Loyalty: Your cafe becomes a special landmark in their personal history.
[How the Event Works]
Participation: Customers use the stationery provided at your shop to write a letter, then register it on our official platform (www.slowpostboxbook.com).
The "Nationwide Tour" Challenge: We run a challenge where participants visit 100 designated coffee shops across the country. By visiting your shop, writing a letter, and earning "Likes" on our app, they become your most dedicated "regular" customers.
[Exclusive Benefits for Partner Cafes]
New Customer Inflow: Enthusiastic participants completing the "100-Shop Challenge" will visit your cafe as a must-stop destination.
Organic SNS Marketing: Customers will naturally share photos of their decorated letters against the backdrop of your cafe on Instagram and blogs to earn "Likes."
Premium Brand Image: Establish your cafe as a warm, emotional space that values "Analog Sentiment" and the "Aesthetics of Slowness."
Marketing Support: Free exposure of your cafe’s location and a dedicated promotional page within our official app/web platform.
[Collaboration Requests]
Space: A small area to display event stationery (B5 or A4 size).
Handling: Once a month, please send the collected letters to our headquarters via registered mail (postal costs to be covered by the cafe).
Incentive (Optional): Small perks for participants (e.g., a free size-up or a small coupon) will greatly maximize participation and engagement.
"Coffee cools in an hour, but a letter written here arrives warm even a year later."
We would love to start this special journey in your beautiful space. We look forward to your positive review and a potential partnership.
Sincerely, SlowPostBox Team
