Tips

01
B2B contact data decays at roughly 30% per year, so contacts older than 12 months likely have outdated information
02
Don't delete high-value contacts without re-enriching first. They may have changed companies but still be good prospects
03
Removing stale contacts can immediately improve your email deliverability by lowering bounce rates
04
Track the re-engagement rate of stale contacts. If less than 2% re-engage, it's more efficient to archive and focus on fresh leads

Frequently asked questions

How quickly does B2B contact data go stale?

B2B contact data decays at approximately 25-30% per year. This means that in a database of 10,000 contacts, roughly 2,500-3,000 will have outdated information after 12 months due to job changes, company changes, and email address turnover.

Should I delete stale contacts or just archive them?

Archive rather than delete. Stale contacts may contain valuable historical data: past deals, conversation history, and notes. Archiving removes them from active lists and reporting without losing the historical record. Only delete contacts that are clearly invalid (spam entries, test records).

How does removing stale contacts improve email deliverability?

Stale contacts often have invalid email addresses that cause hard bounces. High bounce rates signal to email service providers that you have poor list hygiene, which can lower your sender reputation and cause more of your emails to land in spam. Removing invalid addresses keeps your bounce rate under 2% and protects deliverability.
