Growth Wave

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.

Le contexte

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.

Notre approche

  • 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
