Illustrative example
One card · Multiple advertisers
One postcard. Multiple local advertisers.
Shared-postcard advertising brings several businesses together in one mailing. You organize the campaign, work with advertisers, and coordinate the steps that turn individual offers into a finished card.
- Select the area your campaign will reach.
- Bring together a complementary mix of local advertisers.
- Coordinate artwork, approvals, and mailing preparation.
Illustrative example.
From advertiser idea to approved artwork.
A clear, repeatable sequence moves each campaign from planning to a reviewed, approved postcard.
- 1
Plan the campaign
Choose your mailing area and organize the advertiser mix.
- 2
Research and develop
Use the custom GPT to research businesses, review potential category conflicts, and develop proposed offer wording.
- 3
Create the artwork
Generate a complete production prompt, then use it in a separate image-capable ChatGPT conversation to create the advertising tile.
- 4
Place and review
Place the artwork in the postcard template, inspect its fit, and correct wording or positioning when needed.
- 5
Approve and prepare
Obtain advertiser approval for the exact version and complete the required production review before mailing.
Note on the custom GPT
The custom GPT builds production prompts. It does not automatically generate finished, approved, print-ready campaigns in one step.

Choose your mailing volume and subscription options to estimate revenue, expenses, and potential profit from fully sold postcard campaigns.
Include labor, administration, and other expenses for a more complete estimate.
Your estimate
Projected annual income
Based on 12 months of ongoing monthly profit at the current selection. Excludes the one-time $499 setup, taxes, and any expenses you have not entered.
Itemized expense breakdown
Planning estimates based on fully sold advertising, not guaranteed earnings. Revenue assumes $3,567 in advertising sales for each group of 1,000 cards mailed. Profit is before taxes and any expenses you have not entered. Actual sales, collections, costs, and results vary.

A complementary advertiser mix

Spend less effort starting from a blank page.
The AI-assisted workflow helps organize business research, offer decisions, creative instructions, and corrections. You remain responsible for the advertiser relationship, factual verification, and final approvals.
Starting from scratch
- Gather details across disconnected notes.
- Write creative instructions repeatedly.
- Track revisions without a consistent process.
With a guided workflow
- Collect the required information in a structured conversation.
- Produce a complete prompt for the selected advertising tile.
- Follow a consistent placement and approval checklist.
Built for people who connect with local businesses.
Good to know: You do not need to start as a professional graphic designer. You do need to be comfortable working with business owners, learning the tools, and following the review process.
Who can advertise on your postcards?
Local businesses that serve the households in your mailing area are potential advertisers. Build a mix of useful services, everyday purchases, and special offers that gives residents a reason to keep the card.
Keep in mind: These are prospecting ideas, not automatic approvals. Each advertiser should serve the mailing area and have an appropriate, accurate offer. Review overlapping services before placing competing advertisers on the same card. Some industries have additional advertising requirements.
A workflow that can fit your operating model.
Independent operation
Use the training and creative workflow while managing campaign production through your own Mailbox Power arrangement.
Agency-supported operation
Discuss available options for combining the workflow with agency support and account services.
