Is Sharing An Email Address A Breach Of GDPR?

If you’re wondering ‘is sharing an email address a breach of GDPR?’, it could be. In general, if you give permission for an organisation to share your personal data, then sharing your email address might not constitute a breach. However, if an email address is shared without consent or another lawful reason, and you receive marketing emails as a result, for example, this could be a GDPR breach.

Your email address is considered personal information. Personal information or personal data is anything that can be used to identify you, whether directly or indirectly. Your personal data can be held by data processors (organisations that process personal data) and data controllers (organisations who determine the manner in how it will be processed and its purposes).

As such, exposing your email address without your authority or a lawful reason could be considered a breach of GDPR. However, this could only be the case if your address falls into one of two different categories.

Is an email address personal data?

When it comes to your personal email address this could be considered personal data. Your email address could be one you signed up to, such as Gmail, Outlook or Yahoo, for example.

Is my work email address personal data?

Your work email address could be personal data if it contains both your first and last name – one example could be fiirstname.lastname@placeofwork, for example. However, if your work email is from a shared inbox (for example, it starts with ‘info@’ or ‘hello@’) this address would not usually be considered personal data. After all, info@ and hello@ email addresses could be public knowledge, wouldn’t identify you and therefore anyone could access them.

If the sharing of an email address does constitute an email data breach, you could claim compensation if the breach exposes your data and causes you emotional or financial harm. However, in order to claim, you’d need to show that the organisation that was supposed to protect your personal information failed to do so through positive wrongful conduct.

As such, in relation to GDPR and email addresses, you wouldn’t necessarily be able to claim compensation if a company was sold your email address and began to contact you. You would need to prove that your personal data was accessed without your permission through an email data breach, for example, in which the data processor or data controller should have done more to protect your data.   

Below, we explain more about the types of compensation you could receive if an organisation is sharing an email address without permission, GDPR rules surrounding your personal email address, and how breaches could happen.

When Can Your Email Address Be Shared?

Sometimes, if you sign up for products and services, enter competitions or request information from an organisation, you could give out some of your personal data to do so. If you did in the past, prior to 2018 when the UK GDPR was implemented and the Data Protection Act 2018 updated alongside it, your personal data may not have been as well-protected.

Now, under the UK GDPR, giving out email addresses could be considered unlawful in some instances. However, in other instances, it may not be a breach of GDPR. In addition to this, under GDPR, sending personal data by email could be considered a data breach. So too could an email data leak, having personal information sent to the wrong email address, and this could have a number of unwanted consequences.

Organisations can lawfully share your personal information if:

  • You consent to it; or
  • They need to do so to fulfil a contract with you; or
  • They need to do so to comply with the law; or
  • Your life or someone else’s life is in danger and it’s, therefore, necessary; or
  • They’re using it to fulfil a task that’s in the public interest; or
  • They have legitimate business interests

Could I claim?

Under data protection law, if your personal information is involved in a data breach that exposes your personal information and that leads to financial or psychological harm, you could claim compensation.

However, you’d need to show that the organisation you entrusted your personal information to failed to protect it through positive wrongful conduct. For example, they might have not trained staff in data protection, which caused them to share your email address without a lawful basis. This is the type of email data breach you may be able to claim compensation for.

Your email address could legally be shared if you give a company permission. It is essential that you carefully check what you are signing up to when giving out your personal email address. That way, you will be aware of the data you are allowing an organisation to share and whether you are signing up for marketing emails.

If you’re looking into data breaches because of confidential information being sent to the wrong email address, this will be discussed in more detail below.

How Could Your Email Address Have Been Leaked?

There are various ways in which an organisation could expose your email address. One example has been widely reported in the media.

Real Email Data Breach Case Studies

To help illustrate how incorrect use of CC and BCC can contribute to a breach of GDPR that leads to a personal data breach, this section looks at a real email data breach case study from Serco in 2020.

At the beginning of the Coronavirus pandemic in May 2020, the outsourcing company Serco accidentally revealed the email addresses of 300 people training to assist the Government’s “track and trace” service.

The breach occurred when a member of staff wrote an email to the recipients asking them not to contact the help desk for information on their training. However, instead of listing the personal email addresses in the BCC section, all of the addresses were listed in the CC section. This means that instead of being hidden, the personal email addresses of all the fellow trainees were clearly visible.

At least one employee reported this breach to the ICO, and while the firm was not fined, many similar cases have resulted in companies being fined for their misuse of CC and BCC.

Other ways an email data leak could happen

  • Confidential email sent to the wrong email address – this could happen due to an error in typing an email address, or could relate to autofill settings.
  • Forwarding email chains but failing to check personal/private information is removed from the content.
  • Email addresses being hacked due to data not being stored securely or properly.
  • Malicious activity by way of those inside or outside the organisation sharing an email address without permission or another lawful reason.

Is Sharing An Email Address A Breach Of GDPR In Your Case?

If you would like our advisors to check whether an organisation has breached GDPR when sharing email addresses, we would be happy to do so. If we believe you could be eligible for compensation, we could connect you with a data breach solicitor who could help you.

What Can I Do If My Email Was Shared Without My Consent?

When you believe your email has been shared without your consent or without another lawful reason, or an organisation informs you that this has happened, you may be wondering what to do. Should you report the data breach? How do you go about doing so?

Initially, you should take the issue up with the organisation. You may want to ask them for further information on what personal data has been affected. They should work with any affected parties to resolve the issues raised by a breach.

If you’re not happy with the organisation’s response, you could report the issue to the ICO within three months of their final response for them to (potentially) investigate.

My data has been breached; what can I do about getting compensation?

You don’t have to report an email data breach to claim data breach compensation relating to a breach of GDPR when giving out email addresses. However, you would need to prove:

  • Your personal data had been exposed
  • It was due to wrongdoing on an organisation’s part
  • The breach caused harm to you – emotionally, financially or both

If we believe you could have a strong claim, we could connect you with a No Win No Fee solicitor. They could help you fight for compensation.

What Steps Should I Take If My Confidential Information Is Sent To The Wrong Email Address?

(Though confidential information might not always include personal data, in this instance, when we mention ‘confidential information’, we’re using it interchangeably with ‘personal information’.)

If your confidential information has been sent to the wrong email address by a data processor or data controller, they need to inform you as soon as possible. The information they need to provide includes what information has been shared and the potential consequences that come with the sharing of this information. 

The data controller or processor should then notify the ICO of the breach within 72 hours of them becoming aware of it. In terms of answering, “what steps should I take if my confidential information is sent to the wrong email address?”, you could:

  1. Directly contact the company that committed the breach. In some cases, they will admit that confidential information was sent to the wrong email address and offer compensation. 
  2. Make a compensation claim. If you have sufficient evidence that your personal data was shared from an email data breach, for instance, you could receive compensation if you suffered financial loss or psychological harm. You have six years to claim against a private body and one year to claim against a public body. 
  3. Furthermore, you can also make a complaint with the ICO. You do not need to do this in order to receive compensation as this is completely separate from a compensation claim. Therefore, you are able to do both at the same time.
