Two main areas you should focus are:
- The moment your message is sent when you hit the send button
- Identity of the email, which confirms it is actually sent by the person who you think rather than someone else — it’s not a malicious email.
The following tips below will ensure that your email is more secure and trusted from inbox to outbox.
- I would advise not to send any confidential information of any type for example, including National Insurance (NI) number, Bank details, passports, driver license etc. in case it lands in the wrong hands, via email that is not encrypted.
But if do you need to send such information, you can do this by encrypting the entire email itself or send a zip file which is encrypted (there are many but 7zip is one that I use — which is also FREE!).
This way it cannot be read without a password, of course the other person would also need 7zip installed to decrypt and enter the password.
The underlying technology used is called Transport Layer Security (TLS) and all it does is make the message unreadable whilst is moving across the world wide web but does not make it secure when it is stored.
But in order for TLS to work both parties need to support the encryption.
Most email service providers will show you signs that the recipient you are sending or receiving emails from does not support TLS.
I have sent an email from Outlook to Gmail and the screen above shows the email was encrypted and authenticated using TLS.
Below example is what you will see If the email is not encrypted (red unlock icon):

Also make sure that the HTTPS is clearly shown as below, you will notice this same protection scheme when you login to check your bank account or making online purchases.
The best way to find out if your email service provider supports encryption is to check it yourself.
For example Gmail, you can go here: https://transparencyreport.google.com
You can request to download your data and export a copy by creating an archive with your data from Google products: https://takeout.google.com/settings/takeout
For other domains if you want to find out if your email service provider supports encryption is to enter the domain in the URL address bar for example and you will see the lock + https showing.
…continue sending emails securely! #levelitup💻 💪🏽
