Email List Hygiene

A practical example

Example: a marketing team audits its database and suppresses 15% of contacts that have not opened anything in twelve months.

Subsequent campaigns show higher open rates and fewer spam complaints, improving how providers treat future sends.

What to evaluate before investing

• Check whether the platform automatically suppresses hard bounces and repeated non-engagers, or whether this is manual work
• Ask about integrations with third-party email validation services at point of capture and before large sends
• Confirm you can segment by engagement recency so re-engagement and sunset policies are enforceable

Limitations and tradeoffs

Hygiene reduces list size, which can feel like losing assets; the tradeoff is better placement and lower cost per engaged contact.
