Use Case

Send personalized postcards with visual creative via API

Before-and-after photos, property renders, project mockups, service showcases, and promotional offers — designed per recipient from the operator's own targeting data. mailbox.bot turns the approved creative into physical postcards and returns lifecycle events to the campaign system.

Postcards with real visual creative outperform generic text mailers. A roofing company that sends a postcard showing the homeowner's actual roof with a rendering of the finished project gets a different response than one sending a stock-photo template. mailbox.bot lets your agent or software generate the creative per recipient, submit it with campaign metadata, and receive lifecycle events per piece.

Capability Map

What makes visual postcards work

What triggers the postcard?

A building permit, a property sale, a seasonal signal, a CRM event, a lead score threshold, or a scheduled campaign cadence.

What goes on the postcard?

Before-and-after photos of similar projects, AI-generated renders of the recipient's property with proposed work, seasonal promotions, menu highlights, product launches, or service area announcements.

How is each piece personalized?

Your system or agent generates the creative per recipient. Different property photo, different offer, different copy. Submit the final design with campaign metadata so mailbox.bot can return status to the right record.

Why postcards instead of letters?

Postcards are seen immediately — no envelope to open. Visual creative (photos, renders, before-and-after) is the first thing the recipient sees. Higher engagement for outreach and prospecting.

What industries use this?

Home services (roofing, solar, windows, HVAC, landscaping, painting), restaurants and retail, real estate agents, auto dealers, dental and medical practices, and any local business doing area-specific outreach.

What tracking do you get?

Proof photos, delivery tracking per piece, and webhook events for status changes. Reply mail can be forwarded into mailbox.bot through an existing address today; new real mailing and package addresses with scan/photo intake and agent notifications can be reserved now and begin issuing August 31, 2026.

Flow

From targeting to delivered postcard

1
Identify the recipients

Your system selects targets based on permits, property data, CRM events, geographic area, or campaign rules.

2
Generate the creative

Agent or design system renders the postcard creative per recipient — property photos, before-and-after images, personalized copy and offers.

3
Submit and dispatch

POST the final PDF to mailbox.bot with recipient data, campaign metadata, and any approval policy. mailbox.bot prepares the postcard and applies postage.

4
Track and measure

Delivery tracking and photo proof per piece. Route responses (calls, website visits, reply mail) back into the campaign system.

Comparison

Generic mail house postcards vs. API-driven visual postcards

Both put ink on cardstock. Only one lets every piece have different creative tailored to the recipient.
