Direct mail that runs on the tools you already use.

Postie connects to your marketing stack, e-commerce platform, and CRM — so you can run direct mail from the audiences, segments, and signals already living in your system. No dev project. No parallel data model.

How it connects.
Three ways to wire it up.

Method 1: Direct app-level integrations

Point-and-click connections with major marketing, e-commerce, and CRM platforms. Pick your tool, authenticate, and go. Most setups take minutes, not days.

Best for: Shopify, Klaviyo, HubSpot, Iterable, Salesforce

Method 2: S3 or SFTP

Send audience files from your data lake, warehouse, or CDP on a schedule — daily, weekly, or monthly depending on the use case. Postie receives them automatically, no manual work on your end.

Best for: Teams with a data warehouse, CDP, or custom stack alongside a direct integration

Method 3: Pixel and tag manager

Drop the Postie pixel into your existing tag manager. Site behavior starts feeding retargeting and attribution logic immediately — no separate engineering lift.

Best for: Browse retargeting, cart abandonment signals, attribution assist

Automation & Reporting

What happens after setup?

Your audiences stay current. Your mail runs automatically. Your results show up in reporting.

Once connected, Postie keeps your audience data fresh without manual intervention. Most teams set up a few recurring automations and let them run:

• Weekly full audience refresh — first-party lists stay current without manual pulls
• Daily trigger segments — behavior and lifecycle changes update targeting in real time
• Monthly prospecting training sets — feed lookalike and acquisition models with fresh data
• Daily conversion audiences — power attribution matchback and suppression simultaneously

Reporting

Campaign performance lives in Postie natively. If you want results in your own BI stack or analytics environment, data exports are available. You control what gets shared — field by field — so you expose only what you need.
