Automate Continuous Database Hygiene with AutoSMTP
Real-time background verification and automated engagement sunsetting pipelines.
The Inevitable Reality of Email List Decay
Industry research shows that marketing databases naturally decay by 22% to 35% annually. People switch jobs, companies rebrand their domains, and consumers abandon secondary email addresses.
Corporate Turn-Over in B2B
B2B lists decay at the highest rate. When executives change companies, IT departments disable accounts or configure automated bounce-backs that degrade your sender score.
Sunset Policies Save Reputation
Implement an automated sunset workflow: any subscriber who has not opened or clicked an email in 90 days should be removed from active mailing streams.
Re-Engagement Verification
Before launching win-back campaigns on dormant segments, run the list through AutoSMTP SMTP verification to purge addresses that have bounced since the last send.
