The challenge
A database containing hundreds of thousands of contacts creates significant delivery risks when invalid addresses, outdated records, and poor list hygiene are not addressed.
Our approach
Growth Scale Agency worked on cleaning and preparing a database of approximately 680,000 contacts, focusing on verification, suppression, segmentation, and controlled email sending practices. The work included processing approximately 680,000 contacts, email verification and database cleaning, suppression and segmentation, deliverability monitoring, and controlled sending preparation.
The outcome
The project achieved a reported bounce rate below 0.18%, supporting cleaner sending operations and stronger list hygiene.
