The challenge

The brand's list had grown fast through checkout, promotions and discount popups, but quality had decayed. Heading into Black Friday, a high-volume send to a dirty list risked bounces that would damage sender reputation right when revenue mattered most.

The solution

Before the campaign, the team bulk-verified the entire customer database, removed invalid addresses and segmented risky ones. They also added API verification at checkout so new signups were validated in real time.

Frequently asked questions

When should an ecommerce list be cleaned?
Before any high-volume send such as a seasonal sale, and on a recurring basis because lists decay by a few percent every month.
