Bad addresses cost you money. That’s why BirdseyePost includes automated address verification in every campaign — whether you're uploading a CSV, syncing from Klaviyo or Shopify, or targeting a new acquisition audience.

Before a single postcard is printed, our system checks each address against USPS (or Canada Post) databases to make sure it's valid, complete, and deliverable. We catch issues like misspelled street names, missing apartment numbers, or invalid zip codes — and flag or fix them automatically whenever possible.

This ensures your campaigns reach real people — and not the recycling bin at a mail sorting facility.

Why it matters:

• Boosts deliverability and ROI by eliminating undeliverable mail

• Reduces waste and environmental impact

• Protects your brand from looking sloppy or careless

• Ensures compliance with postal regulations for bulk mail

• Improves campaign performance metrics by cleaning bad data before launch

Address verification runs in the background of every BirdseyePost campaign — you don’t have to lift a finger. But you’ll always be able to review any flagged addresses before we print, giving you full visibility and control.

It’s especially useful for CSV uploads, older customer databases, or B2B lists where addresses may be outdated or incomplete.

Whether you’re sending to one neighborhood or 100,000 homes, we make sure every piece has a valid place to land.
