Clean in layers
- Suppress hard bounces and prior unsubscribes.
- Merge duplicates without overwriting the newest valid preference.
- Flag generic, malformed, and suspicious addresses.
- Document source and permission where available.
- Separate active clients, former clients, prospects, and referral sources.
- Re-engage long-inactive subscribers before pausing them.
Don't use opens alone
A reader can be interested without loading tracking pixels. Consider clicks, replies, site visits, registrations, relationship status, and recency together.
Preserve operational records
Suppressing marketing email is different from deleting matter records or required business data. Coordinate CRM cleanup with the firm’s retention, privacy, and conflicts obligations.
Create a repeatable policy
Run light hygiene continuously and a deeper review quarterly. Define who can import contacts, which source fields are required, and how preferences flow between systems.
How to re-engage the people worth keeping
First, audit the list
Separate subscribers with clear permission from contacts collected for another purpose. Remove hard bounces, obvious role accounts, duplicates, and addresses that should never have entered a marketing list.
A three-message re-engagement plan
- Reconnect: Explain who you're, why the person is receiving the email, and what useful content is available.
- Offer a choice: Let readers choose practice areas, topics, or frequency.
- Close the loop: Tell nonresponders you will pause marketing email unless they choose to stay.
Make the value concrete
“Stay subscribed for updates” is weak. Promise a defined benefit: a monthly estate-planning reminder, a quarterly employer-law update, or a weekly appellate digest.
Protect deliverability
Send in controlled groups, monitor bounces and complaints, and stop if the data indicates the list isn't healthy. A smaller permission-based audience is more valuable than a large resentful one.
