Gmail, the free email service from Google will now warn you should your recipient not using secure email.
It will show you an open pad lock by way of telling you your intended recipient is using a service which does not support encryption.
Clicking on the padlock will give clear message such as “If your message is sensitive, consider removing these addresses or deleting any confidential information…”
This is a good thing and something we expect from corporations like Google. It is another step forward to an ever changing and more privacy conscious world.
