Transactional and lifecycle mail share a brand, so one bad campaign can degrade password-reset delivery.
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 SaaS companies#
- 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 SaaS companies#
Transactional and lifecycle mail share a brand, so one bad campaign can degrade password-reset delivery. Weight your effort toward the steps above that address this constraint first, and measure with metrics that match how SaaS companies 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.
