Email systems are often the biggest data retention risk. Here’s what compliance and IT need to fix.

Email is often overlooked in data retention strategies — yet it’s where the most unstructured personal data lives.

Archived emails may contain salary details, medical information, and candidate records — often held for years without review.

UK GDPR principles at risk:

  • Storage limitation – keeping data “no longer than necessary”
  • Integrity & confidentiality – increased breach risk from over-retention

Action steps:

  • Implement email retention policies (e.g. 2–5 years max)
  • Use tools to auto-delete or archive based on keywords and age
  • Train staff to avoid using email as permanent storage

Email is not a filing cabinet. Treat it like a live data source — and control what’s inside.
