Last Updated On 12th March 2026. A wrong email address data breach occurs when personal, sensitive, or confidential information is mistakenly sent to an incorrect recipient via email. Whether the data breach was caused by a failure to use Blind Carbon Copy (BCC), attaching the wrong file, or mistakenly using autocomplete, sensitive personal data can be exposed, including names, addresses, and medical information. According to the data security incident reports from the Information Commissioner’s Office (ICO), there were 2,459 reports in 2025 of emails being sent to the wrong recipient.
The UK General Data Protection Regulation (UK GDPR) and the Data Protection Act (DPA) are the fundamental laws governing how personal data is processed. If an organisation fails to comply with these laws and you suffer mental and/or financial harm as a result, you could make a data breach compensation claim.

What Are Wrong Email Address Data Breach Claims?
Personal data is data that can identify you as a person. For example, this might include information such as your full name, your phone number, or your email address. Personal data also includes special category data. This is a kind of personal data that, due to its sensitive nature, requires extra protection.
A wrong email address data breach can arise if an email containing personal data is sent to the incorrect person. When a security incident such as this allows the confidentiality, integrity, or availability of your personal data to be compromised, this is a personal data breach.
Data controllers and data processors must comply with data protection laws. A data controller is in charge of deciding how your data will be used, as well as why. A data processor goes on to process this data on behalf of the controller.
The UK GDPR sets out the criteria that claims have to meet to be valid for compensation. According to this legislation, you have to be able to prove that the breach:
- Includes your personal data
- Is the fault of the data controller or processor
- Has caused you to experience harm

Causes Of Wrong Email Address Data Breaches
There are many ways in which a personal data breach can occur. However, as we have previously mentioned, you can only make a claim for compensation if the breach was the fault of the data controller or processor. With this in mind, wrongful conduct that could lead to an email data breach may include the following:
- An employer accidentally sends an email that contains personal data to the wrong person
- The wrong person is copied into an email, allowing them access to the personal data
- An employee accidentally attaches the wrong document to an email, allowing the recipient unauthorised access to personal data
What To Do Immediately After Sending An Email To The Wrong Address
If an email has been sent to the wrong recipient containing personal data, you should take immediate action to reduce the risks of causing mental and financial harm. As such, please see the following steps that could be taken, which are commonly recommended by data protection professionals:
- Try to recall the email. If you’re using Gmail, you may be able to click ‘Undo’ at the bottom of the screen immediately. Similarly, if you’re using Microsoft Outlook, you may be able to use the recall feature by going into your ‘Sent Items’.
- Contact the unintended recipient. If the recall window closes, you could contact the person who received the incorrect email. In doing this, you could politely ask them to delete the email before viewing it and to confirm when done.
- Report the incident within your organisation. If the email contained sensitive, personal, or confidential information, you should formally report the incident to a data protection officer (DPO), your manager, or your IT department so the breach can be officially recorded.
- Decide whether the breach should be reported to the ICO. If the personal data breach is serious, you must report the incident to the ICO within 72 hours if it compromises people’s freedoms or rights.
- Document the email data breach. You should record the date and time that the email was sent, what information was compromised, and how the incident occurred. This will help to support any future claims or investigations.
Even if you’re not able to recall an email sent to the wrong address, taking the above steps will demonstrate that measures were taken to protect and rectify a personal data breach.

What Are The Impacts Of A Personal Data Breach?
The impacts of a personal data breach can be serious and far-reaching, affecting both your mental health and your finances. For example, a credit or debit card data breach could lead to criminals stealing money from your bank accounts or making illegal purchases on your credit card.
If you have experienced a personal data breach, this might also lead to experiencing mental health problems as a result. For example, you could suffer stress after a data breach, or you could experience anxiety caused by the breach.
What To Do If Your Email Is In A Data Breach
If an organisation experiences a personal data breach that can affect your rights or your freedoms, they must contact the ICO and report it. They must also notify you as soon as possible.
If you receive notification of a personal data breach or if you suspect your personal data has been compromised, you can make a complaint to the organisation responsible. They may be able to confirm the breach or provide more information.
If their response is not satisfactory, or if they do not respond at all, you can make a complaint to the ICO. Do this within three months of your last meaningful contact with the organisation. Whilst the ICO does not award compensation, they can still investigate the breach and any correspondence can be used to strengthen your claim.

Calculating Wrong Email Address Data Breach Settlements
Notably, data breach compensation can be seperated into two heads of losses that you could be awarded with if your claim is successful. Material damage is the head of claim that provides compensation for the financial impacts of the personal data breach. This can include a loss of earnings, damage to your credit score, or debt accrued in your name.
Non-material damage offers compensation for any emotional distress or psychological injuries that you suffer as a result of the breach. For example, you may suffer distress, depression, or post-traumatic stress disorder (PTSD).
The table below showcases figures taken from the Judicial College Guidelines (JCG) in relation to non-material damage awards. Please note that the brackets in this table are guidelines only, as the JCG provides solicitors with guideline compensation amounts to help them value claims. Please also note that the top figure has not been taken from the JCG.
| Harm To Mental Health | Severity And Injury Notes | Compensation Payout |
|---|---|---|
| Multiple Instances of Severe Harm and Financial Losses | Severe - including material damage such as therapy costs and lost earnings. | Up to £250,000+ |
| Mental Injury | Severe - Overall, this person has been severely impacted across multiple areas of life. They have a bad prognosis. | £66,920 to £141,240 |
| Mental Injury | Moderately severe - The impact has been similar to the most severe cases, but there is a better and more optimistic prognosis. | £23,270 to £66,920 |
| Mental Injury | Moderate - Significant improvements can be seen in symptoms by the time of trial. The prognosis is much better. | £7,150 to £23,270 |
| Mental Injury | Less severe - Compensation payouts depend on symptoms' effect on daily life. | £1,880 to £7,150 |
| PTSD | Severe - As a result of the trauma, the person is not able to return to functioning or working at the same level they did before. | £73,050 to £122,850 |
| PTSD | Moderately severe - With professional treatment, there is some chance of recovery. | £28,250 to £73,050 |
| PTSD | Moderate - While there has been a large degree of recovery, some non-disabling symptoms may continue. | £9,980 to £28,250 |
| PTSD | Less severe - In around two years, an almost complete recovery has taken place with only minor symptoms that continue. | £4,820 to £9,980 |
