How technical person can write good corporate email
I think that engineering email is complex as any other engineering. Emails should properly code and wire quantum neural networks of Homo Sapiens you communicate to. There are good tools to make the technical part right. Please give a try for next steps:
Do 1, 2 and 3 again. Experiment if and as necessary.
Tools compile and validate your text, but the design is up to you. There is no tool to properly structure your email and choose right recipients.
Feel free to contact me with any suggestions to improve this guide.
P.S. Be careful pasting top secret and very confidential texts into 3rd party tools.
