In the digital age, email has become a popular communication and information sharing tool. However, sending emails and attachments containing sensitive data poses many risks if not done properly. Here are 5 common mistakes that many people make when sending emails containing sensitive data:

  1. Sending unencrypted email:

Sensitive data such as financial information, medical records, or confidential business information should be protected by email encryption. This applies to files sent as attachments as well. Sending unencrypted emails makes data vulnerable to theft by hackers or unauthorized users.

  1. Sending emails to many people unnecessarily:

Emails containing sensitive data should only be sent to those who really need it. Sharing data with too many people increases the risk of information leaks.

  1. Attaching files is not safe:

Instead of directly attaching files containing sensitive data, use a secure cloud storage service with encryption such as 689Cloud SecureMail and share a link to the file instead of attaching it.

  1. Use weak passwords:

Your email password should be strong and difficult to guess. Avoid using the same password for many different accounts.

  1. Not using anti-virus and anti-malware software:

Antivirus and anti-malware software help protect your computer from cybersecurity threats, including data theft.



  • Use an email service with encryption like Gmail or Outlook.
  • Use cloud file sharing services with encryption instead of attaching files..
  • Install anti-virus and anti-malware software on your computer.
  • Use strong and unique passwords for each account.
  • Only send emails containing sensitive data to those who really need it.
  • Be careful when opening emails and attachments from unknown senders.

By following the advice above, you can minimize the risk of sending emails containing sensitive data and protect your information from attackers.

Data security is an important issue in the digital age. Be careful when sending emails containing sensitive data to protect your information from potential risks.
