Carewell Uses Lob Address Verification API to Build Customer Loyalty and Cut Costs

https://www.carewell.comCarewell, an online retailer of healthcare products, prides itself on being a trusted partner to caregivers. But their team noticed a recurring issue: packages were being returned due to undeliverable addresses, especially when customers forgot to include apartment or facility details.
Each return came with added shipping costs and a bigger risk: damaged customer trust. Some caregivers never received what they ordered. Others received shipments late. Even when the issue stemmed from a bad address, customers blamed Carewell.
To solve this, Carewell first tried shipment tracking software to catch delivery problems in progress. Then they tested a lightweight address verification tool, but it didn’t tell them why an address was undeliverable. In many cases, it flagged a missing suite number even though delivery was still possible.
That’s when Carewell turned to Lob.
With Lob’s Address Verification API and detailed documentation, the team implemented a new workflow in just four hours. Now, every order is verified before it's sent, helping the team fix incomplete or ambiguous addresses before they become a problem.
- Lob reduced undeliverable mail and cut shipping costs by $5,000/month
- Address validation stopped delays before they happened
- Welcome letters and printed communications are now automated through Lob’s Print & Mail API
- Fewer complaints, stronger relationships with caregivers
“Customers are no longer blaming us for wrong addresses.”
