70% invalid contacts. -80% bounce rate after the audit.
A decision-maker database built over years, but without maintenance: nearly 7 in 10 contacts unreachable. Campaigns were bouncing, deliverability was dropping. We audited, cleaned and segmented the entire base.
The context
A database that grows without maintenance becomes a liability. Without email verification or job-change detection, years of commercial work depreciate silently. The bounce rate was penalizing campaigns and flagging a systemic problem to email providers.
Our approach
- →Full audit: email verification, detection of invalid addresses, hard bounces, spamtraps
- →Multi-pass cleaning: removal of unrecoverable contacts, correction of malformed addresses
- →Segmentation: active contacts, cold, to re-engage, to remove
- →Entry validation process set up to prevent re-contamination
