Stale Contact Cleanup Checklist
Identify, re-engage, or remove stale contacts from your CRM to improve deliverability, reporting accuracy, and sales team efficiency.
Identify Stale Contacts
Define your staleness threshold
easyDecide what 'stale' means for your business: no activity in 6 months? 12 months? No email opens in 90 days? Document the criteria.
Create a stale contacts report
easyBuild a CRM report or filter to find contacts with no activity (email opens, replies, calls, meetings) beyond your staleness threshold.
Segment stale contacts by value
mediumSeparate high-value stale contacts (enterprise accounts, previous customers) from low-value ones (old event attendees, content downloads).
Re-Engage or Re-Enrich
Re-verify email addresses for stale contacts
easyRun email verification on stale contacts — many will have changed jobs or email addresses. Remove invalid emails to protect sender reputation.
Re-enrich high-value stale contacts
mediumUse Cleanlist to update job titles, companies, and email addresses for valuable stale contacts. Many will have changed roles but still be good prospects.
Run a re-engagement campaign
mediumSend a targeted re-engagement email to stale contacts with verified emails. Use a compelling subject line and clear value proposition.
Clean & Archive
Remove contacts with invalid emails
easyAfter re-verification, remove or archive contacts whose emails are confirmed invalid. These hurt your deliverability metrics.
Archive non-responsive stale contacts
easyContacts who didn't engage with re-engagement campaigns should be moved to an archive status to keep your active database focused.
Set up automated staleness detection
mediumCreate a CRM workflow that automatically flags contacts as stale when they hit your inactivity threshold, triggering re-engagement or cleanup.
Pro Tips
- B2B contact data decays at roughly 30% per year — contacts older than 12 months likely have outdated information
- Don't delete high-value contacts without re-enriching first. They may have changed companies but still be good prospects
- Removing stale contacts can immediately improve your email deliverability by lowering bounce rates
- 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.
