If you use Gmail, you already have encryption built in as your emails go through Google’s servers. Gmail uses S / MIME to support advanced encryption and also encrypts your outgoing emails when possible. However, Gmail encryption does not protect your email when it reaches its destination, and this is a serious limitation.
If you regularly send and receive sensitive emails through the Gmail system, you might want to strengthen your encryption Fortunately, there are several free plugins to help you secure every message you send.
Some require you to provide a password, while others decrypt at the other end without it. You will also have the option to use an encryption tool that prevents email from being stored on any mail servers.
FlowCrypt
FlowCrypt
After installing the FlowCrypt plug-in, a new green button will appear in the message compose field that says “Encrypt and Send”. As you write, the program will automatically encrypt your message as it is saved, so your information will be encrypted even before you send it.
This means that even drafts that you save but don’t send will be encrypted. If the subscriber on the other end does not have FlowCrypt, you will need to provide a password and pass it on to the recipient before they can access the emails.
Lockmagic
Lockmagic
Lockmagic uses a much more covert encryption button, placing it next to the regular Submit button. This makes it ideal for those who only need to encrypt a message from time to time.

One of the best features of Lockmagic is that it eliminates the need to add a password and share it with each recipient. You will also receive a notification every time you open a message, allowing you to track any suspicious activity.
Mailing envelope
Mailvelope
The standard version of Mailvelope is quite tricky to set up as you have to manually set the keys. If you have Gmail, the plugin was designed to work out of the box.
Emails are encrypted in transit and you can encrypt attachments as well. If you would like to add another internet email provider, you can do it with one click, if that email provider is supported. Currently, Yahoo! Besides Gmail, Mail, Outlook.com and GMX are supported.
Snapmail
Snapmail
You’ve probably heard of Snapchat self-destructing messages. Snapmail uses a similar concept, giving recipients 60 seconds to read a message before it disappears forever. The email is encrypted as it is sent to the other party, and the recipient receives a link to read the message.
Of course, nothing prevents the recipient from taking a screenshot of the message so that they can access it later, but this is safe because the message is not stored on the server indefinitely.
The right encryption tool will give you peace of mind, especially if you need to send sensitive information such as account numbers and contact information. Make sure you choose a tool that not only protects your data but is also easy to use on the recipient’s side.
