Every business inbox is full of personal data: customer names, phone numbers, addresses, CVs, invoices and sometimes far more sensitive information. That makes email one of the most important systems to consider under data protection law. Here’s what businesses need to know.
This article is general information, not legal advice. Consult a qualified professional about your specific obligations.
Which laws may apply
- GDPR (EU and UK). Applies to organisations handling personal data of people in the EU or UK, wherever the business is based.
- Sri Lanka’s Personal Data Protection Act No. 9 of 2022 (PDPA). Sets out obligations for organisations processing personal data in or from Sri Lanka.
- Other national and sector rules, such as those covering finance, healthcare or government contracts.
While details differ, these laws share common principles that apply directly to email.
Key principles and what they mean for email
Security of processing. You must protect personal data with appropriate technical and organisational measures. For email, that means strong filtering, malware protection, two-factor authentication and access controls.
Data minimisation. Only collect and keep the personal data you need. Avoid sending unnecessary personal information by email, and don’t keep messages forever without reason.
Accountability. You must be able to show how you protect data. Documented policies, admin logs and clear security settings help.
Processor relationships. Your email provider processes personal data on your behalf. You should understand where data is processed, which other parties are involved and what security measures are in place.
Breach response. Many laws require organisations to assess and, in some cases, report personal data breaches within set timeframes. A compromised mailbox can be a reportable breach.
Practical steps for compliant email
1. Choose a business-grade provider with clear security features and business terms.
2. Enforce two-factor authentication to reduce the risk of account compromise.
3. Restrict access by country so mailboxes can only be reached from where you operate.
4. Filter threats before delivery with AI-driven antispam and virus scanning.
5. Understand AI processing: prefer services that analyse email on their own servers rather than sending content to external AI providers.
6. Set retention rules for how long email is kept.
7. Train staff on handling personal data and spotting phishing.
8. Have an incident plan for suspected mailbox compromise.
Common compliance mistakes
- Staff using personal free email accounts for customer communication.
- Sending large spreadsheets of customer data as unprotected attachments.
- No process to remove access when employees leave.
- No visibility into what the email provider does with data.
