How To Securely Send Files Via Email

Email is one of the most commonly used document-sharing channels present day. Since it is able to accommodate the transferring of practically any file type, email can address several different use cases within your company.

Although email is convenient and efficient, that doesn’t change the fact it simply is not secure. Unfortunately, cybersecurity threats have increased since the onset of the pandemic. Many companies switched to remote work which meant a lot of information being uploaded to the internet – and hackers took advantage. Phishing attacks, the most common malware attack, have increased and a whopping 94% of malware is delivered via email in an attempt to steal personal information. Due to the lack of encryption and security provided by email, it’s not very safe to share files via email. So how can you securely send files via email?

In this article, we will share pro tips for protecting your files and sharing them online.

Why Should You Secure Your Email Attachments?

Email attachments have sensitive information that is intended only for the recipient. However, experienced hackers can easily intercept the transmission, gain access to your data, and use it with malicious intent. This can be disastrous if the attachments have sensitive information such as credit card details, client data, or other sensitive information.

Currently, it’s very easy for hackers to intercept electronic mail before it arrives in the intended recipient’s inbox. Since email is not encrypted, any information travelling from one computer to the next can easily be stolen, altered, or damaged. That’s why it’s important to prevent these occurrences by taking the necessary precautionary measures to avoid information leakage.

What Type of Documents Can You Send Via Email?

Many email providers allow you to send different file formats as email attachments. In fact, you can send any file if it does not exceed the size limit set by the provider. For example, Gmail file attachments should not be more than 20 MB.

.word and .pdf are the most common file types people add as email attachments, but the list is long. You can send any of the following:

  • Text files (.doc, .docx, .txt)
  • PDF documents (.pdf)
  • Presentations (.ppt, .pptx)
  • Spreadsheets (.xls, .xlsx)
  • Images (.jpeg, .png, .gif)
  • Sound files (.mp3, .m4a)
  • Video files (.mp4, .mov, .avi)
  • eBooks (.mobi, .epub)

How To Securely Send Documents Via Email

If someone correctly guesses the password, they get unlimited access to your inbox, outbox, and customized folders.
