The Most Common GDPR Errors in Managing Business Email

Why Email Communication is a Critical Point for GDPR

Business email accounts are often at the center of internal and external communications, containing personal information of clients, suppliers, and employees. Documents, sensitive data, contracts, and communications involving personal data are sent, stored, and shared daily via email, turning it into a potentially vulnerable digital archive.

According to GDPR, any processing of personal data requires appropriate technical and organizational measures. This means that email, a widespread and practical tool but also exposed to risks, must be managed in compliance; otherwise, the company risks hefty penalties. Therefore, it is essential to know the most common errors and how to prevent them.

Improperly Protected Access

One of the most frequent errors concerns how access to email accounts is handled. Weak passwords, credential sharing among colleagues or external agents, and lack of two-factor authentication compromise the security and integrity of the personal data processed. It is often underestimated how easily unauthorized access can lead to data breaches.

Recommended measures:

• Set strong passwords and enforce periodic password changes.
• Use multi-factor authentication systems.
• Limit access to only those with a genuine need and monitor logs.

Managing Employees’ Accounts and Mailboxes

When an employee leaves the company or changes roles, it is crucial to properly manage the associated emails. The most common mistake is keeping mailboxes active and accessible without controls, exposing personal data and risking issues like undeleted information or improper use.

Best practices include:

• Promptly disable email accounts after employment ends.
• Archive relevant emails according to company policies, respecting GDPR retention periods.
• Avoid unauthorized sharing or continued access by unqualified personnel.

Email Retention and Deletion: Errors and Solutions

Many companies do not define and document clear policies for email retention, leading to over-retention or premature deletion that violate data minimization and storage limitation principles. Keeping data longer than necessary exposes it to attacks, while deleting too early can impede compliance with legal retention obligations.

Best practices include:

• Define retention periods based on data type and processing purposes.
• Automate archiving and deletion processes to reduce manual errors.
• Track decisions and procedures to demonstrate compliance.

Sharing Personal Information and Automatic Forwarding

Automatic forwarding rules are often configured without considering the risks of unauthorized transfer of personal data, especially to external accounts or uncertified cloud services. Data exchange with third parties must always respect privacy, with prior supplier assessment and proper agreements.

To avoid risks:

• Limit automatic forwarding to protected internal accounts.
• Check and validate third-party providers managing email data (including cloud services).
• Document all authorizations and forwarding rules in the processing register.

Using Personal Devices for Workplace Email Access

Many employees access corporate emails via personal smartphones or PCs, increasing vulnerabilities related to malware, theft, or device loss. Without proper controls, there is a risk of violating personal data privacy stored or transmitted via email.

Guidelines to follow:

• Implement BYOD (Bring Your Own Device) policies with minimum security requirements.
• Use encryption systems for email communications and stored data.
• Ensure remote wipe capability in case of loss or theft.

Choosing, Managing, and Securing Email Service Providers

The selection of an email service provider is a crucial issue for GDPR compliance. It’s not enough to aim for cheap or mass solutions; it’s essential to carefully evaluate security, data localization, and regulatory adherence, including digital sovereignty.

Managing Suppliers and Documentation

GDPR regulation cannot be properly addressed without diligent management of suppliers (data processors). They must adhere to the same standards required of the data controller, and the selection must be based on a thorough risk assessment of technical and organizational factors.

All decisions involving email management, security policies, and collaboration with suppliers must be documented and regularly updated to produce evidence during audits.

Practical Checklist to Identify Critical Issues and Reduce Risks

• Access: check password policies, MFA, and access logs.
• Employee accounts: clear procedures for deactivation and archiving after employment ends.
• Retention and deletion: define timelines, automate processes, and maintain records.
• Data sharing: forwarding rules, third-party safeguards, confidentiality agreements.
• Personal devices: BYOD policies and security measures.
• Suppliers: assessment, agreements, and ongoing monitoring.
• Documentation: activity logs, policies, and updated decisions.

Conclusions

Managing corporate email in compliance with GDPR is complex, but understanding and correcting common errors greatly reduces risks and enhances personal data protection. It is a responsibility shared across all company levels, from DPOs to IT managers and business owners. Only with a proactive and structured approach can email management be secure, transparent, and compliant with regulations.
