Email List Decay Rate
Email list decay rate is the speed at which contact data becomes outdated as people change jobs, companies, inboxes, or buying relevance over time.
Email List Decay Rate
Email list decay rate measures how quickly a prospect list becomes stale.
Even good lists degrade. Titles change, people switch companies, inboxes get disabled, and accounts fall out of scope.
Why it matters
Higher decay creates more bounces, more irrelevant outreach, and more sender-risk. That reduces conversion quality and eventually hurts inbox placement.
How teams control it
- refresh data on a cadence
- verify addresses before large sends
- remove stale or unengaged segments
- monitor bounce patterns by source
