What is a postcard template for direct mail?

A postcard template is a reusable layout that defines where fixed creative, address content, response paths, and variable fields appear before a campaign is approved for print.

The template is not just artwork. It is a production record that should connect design decisions to address space, variable data, proof approval, campaign IDs, and batch release.

What should the template record include?

A useful postcard template record should make the layout, data contract, and approval history clear enough for operators to review before release.

Template fieldWhy it matters
Postcard sizeConnects the layout to the selected physical format.
Design zonesSeparates headline, offer, response path, address area, and production marks.
Address spaceKeeps the recipient block and postal context visible during proofing.
Variable fieldsNames each merge field and the source record that supplies it.
Fallback copyShows what prints when a variable value is missing or held.
Proof versionConnects the template to the approved production view.
Usage recordLinks the template to campaign IDs, batch IDs, and later audit review.

How does variable data fit after consolidation?

Variable data is now part of the postcard template record. The template should list each variable field, the expected source value, fallback copy, proof example, and whether a missing value should hold the record.

This keeps personalization tied to proofing and release. For proof-specific review, see the print proof guide. For the event data entering the workflow, see the event payload guide.

How should templates connect to proofs?

A template should not be treated as approved until a proof shows the final version with real or representative data. The proof should show address layout, variable fields, fallback values, response paths, and any fields that may hold a record.

Keep the approved proof version attached to the template version and batch record. That makes it easier to explain which design was used for each mailing.

What should a template not decide?

A template should not decide whether a record is eligible to mail. Address readiness, suppression, duplicate-send checks, approval queues, and batch release decisions need their own records.

Use the workflow hub, list hygiene hub, and approval queue guide for those adjacent controls.

FAQ

What should a postcard template include?

It should include postcard size, design zones, address space, barcode context, template version, merge fields, fallback copy, proof version, and usage records.

Is variable data separate from the template?

No. Variable data should be documented inside the template record and verified during proof review.
