This guide from Pangea explains everything you need to know to make your email more secure, beginning with plain-language explanations of the concepts involved and then moving on to the tools you will need and easy-to-follow instructions on how to use them.
In my line of work I spend a big part of my day sending and receiving emails. In this post I will try to clarify the concepts and practices of emailing in the hope that I might save some inbox congestion for some people, and some carbon dioxide from the planet’s atmosphere.
