Agencies send on behalf of many client domains and must isolate reputation per client.
What email data retention is#
Data retention policy defines how long mailbox data and marketing records are kept and when they are deleted. DSARs (data subject access requests) require producing or erasing a person's data on request.
Why it matters#
GDPR and similar laws require minimization and timely response to requests; over-retention increases breach exposure.
Implementation plan for marketing agencies#
- Classify data: consent records, engagement logs, message content.
- Set retention periods per class and automate deletion.
- Build a DSAR process that can search and export across ESP, CRM, and mailbox.
- Log every deletion and export for accountability.
Priorities specific to marketing agencies#
Agencies send on behalf of many client domains and must isolate reputation per client. Weight your effort toward the steps above that address this constraint first, and measure with metrics that match how marketing agencies generate value from email.
Common mistakes#
- Deleting consent records that you need to defend a complaint.
- No process for AI tools that have processed mailbox content.
Frequently asked questions#
How long can I keep unsubscribed contacts?
Keep the suppression record indefinitely (email only) so you never re-mail them; delete profile data per your retention schedule.
