Email lists decay as people change jobs or switch email providers, or because an address was wrong when it was entered. To counter this, we recommend regular email verification to remove expired, invalid or unwanted emails from your list.
Any email list will decay at a rate of around 22.5% each year1. Regular maintenance is needed to avoid high bounce rates while keeping conversion rates healthy.
Why does my email list decay over time?
- Job change
- ISP change
- Fake: sometimes people use fake emails
- Disposable
- Syntax error
Our email verifier will tell you whether an address is valid and flag any risks associated with it.
