Whether you’re emailing over confidential documents for work or in your everyday life, knowing how to keep your information secured properly is crucial. Confidential documents often include personal information, financial data, or private business updates.

In 2021 alone, almost 309.6 billion emails were delivered and accepted. This figure is anticipated to increase to 376.4 billion in 2025. Businesses and individuals use email as an important communication channel because it’s accessible, cheap, and fast.

However, email is not always a secure channel for sending and receiving sensitive data. If you’ve ever been worried and searched “how to send a confidential document via email”, you’ve come to the right place.

Let’s look at all the steps you can take to ensure the safe transmission of private information through email.

Should You Send Confidential Documents Via Email?

If you want to protect private and confidential information, then sharing it via email isn’t a good idea. A confidential document sent via email can be easily intercepted and exposed to hackers or third parties.

Why do you need to protect a confidential document in the first place? Sensitive data usually consists of private information that a business may not be ready to release. Failure to protect it with a password or encryption can lead to theft or misuse.

In addition, many businesses that fail to handle their confidential information face lawsuits and may lose their reputation and money.

If you have no choice but to send confidential information via email, you should avoid sending information such as social security numbers, passport numbers, credit and debit card details, bank account numbers, and passwords. Make sure you are careful with what you plan to send and take all steps to protect it. Don’t forget to check you have the recipient’s correct email address.

How to Send Confidential Documents via Email

If you have no choice but to send confidential information over email, there are a few ways you can try to make sure your documents are as protected as possible. The most common way is to activate password protection and email encryption.

Here are some general steps to follow to protect your Word documents before sending them out. You can also use a similar process to place a password on your PDF file.
