Keep identifiable data from browser-based email tests only as long as it is needed to run the test and correct resulting errors. There is no general legal or industry-wide number of days: the right boundary depends on the test’s purpose, the data involved, and the systems that hold it.
When should test emails be deleted?
Delete test messages and related personal data when the test and any necessary error correction are complete. If a specific debugging need justifies keeping data longer, define that need and its end point rather than relying on an open-ended retention period.
This approach follows two GDPR principles. Article 5(1)(e) says identifiable personal data must not be kept longer than necessary for its processing purpose; Article 5(1)(c) says data must be adequate, relevant, and limited to what is necessary. Controllers must also be able to demonstrate compliance. Read GDPR Article 5.
The Court of Justice of the European Union addressed a closely related situation in Case C-77/21, Digi. It held that storage limitation precludes keeping personal data in a database created for tests and error correction longer than necessary to conduct those tests and correct those errors. The case supports a purpose-based endpoint, not a fixed number of days for every test. Read the CJEU judgment in Case C-77/21.

How long should a test inbox keep messages?
Set a period that ends when the particular test purpose is satisfied. A short-lived delivery check may need no post-test retention; a test that requires investigating a reproducible error may need a defined debugging period. The duration should follow the task and the minimum data needed to complete it, rather than a vendor example or a convenient default.
The cited legal sources establish necessity, not a universal number of days. Two service-specific examples illustrate why a provider’s figure should not be treated as a general rule:

What counts as test email data?
A retention boundary should cover more than the visible message in the inbox. Depending on the tool and configuration, the data may include account identifiers or credentials, mailbox and message metadata, text and HTML bodies, raw RFC 5322 source, headers, attachments, authentication results, and service logs.
One sandbox policy describes message expiry through a configured cleanup job or per-message expiry, and deletion through its UI or API where implemented. It also says backups, logs, and snapshots are controlled by the instance operator. That is one service’s disclosure, not a description of every sandbox. Read the sandbox privacy policy.

How to set a workable deletion boundary
- Define the test purpose. Record what the test is checking and what error-correction work may follow.
- Minimise what you collect. Use only the message fields, identifiers, and operational data needed for that purpose. Avoid real personal data when the test can be performed with synthetic data.
- Set an end point. Choose a deletion trigger tied to completion of the run and any justified debugging period. Assign an owner to decide when that work is finished.
- Map every data layer. Check whether expiry or deletion covers the inbox, raw messages, attachments, metadata, logs, snapshots, backups, and copies held by subprocessors.
- Verify controls and exceptions. Confirm whether expiry is automatic, whether per-message expiry or UI/API deletion is available, and whether contractual, legal, dispute, or plan-specific terms affect deletion.
- Keep evidence of the rule. Document the purpose, retention trigger, system coverage, and relevant vendor terms so the organization can show how it applies the boundary.
Do browser email testing tools delete test data automatically?
Some tools describe configured expiry or manual deletion controls, but those controls may not cover every copy or data layer. A message disappearing from the inbox does not by itself establish that related logs, backups, snapshots, or subprocessor copies have also been deleted. Check the tool’s actual documentation and contract, and identify who controls each store.
When comparing tools, evaluate the scope of data covered, deletion triggers and controls, backup and subprocessor handling, purpose-linked exceptions, and whether the provider’s privacy information matches its actual processing. A headline retention figure alone cannot answer those questions.

When should privacy information be updated?
In the UK GDPR context, the ICO’s guidance says organizations should update privacy information and proactively bring changes to people’s attention before starting processing for a new purpose. It specifically includes the retention period for personal data used for that new purpose, and says notices should be reviewed for accuracy and currency. The cited ICO guidance is dated 2018, so check the current guidance before relying on it. Read the ICO guidance on data protection principles.
