Why Direct Mail Fails at the Lobby Door (And How to Fix It)

A valid street address and postal code still won’t get your direct mail delivered if a customer lives in an apartment or condo. Without the unit or suite number, Canada Post carriers simply have to return the piece as undeliverable.

The printing and postage costs are spent, but your customer never sees the campaign.

StampIT! by Prism Data Services eliminates unit-level delivery failures before your files go to print:

  • Catches Missing Unit Numbers: Cross-references records against official Canada Post data to append missing apartment and suite details.
  • Secures Bulk Postage Discounts: Generates an official Statement of Accuracy (SOA) certificate directly from your data run.
  • Fits Your Workflow: Clean contact lists quickly via StampIT! Online or automate processing behind your firewall with StampIT! Server.

Stop paying to print direct mail that stops in the lobby.
