Evaluate how personal the email is.
If an email contains a bit of small talk at the beginning and is quite personal, you are probably dealing with a Green or Yellow. But if it gets straight to the point and is very formal, it’s probably a Red or Blue.
Determine what information it contains.
A vague email that doesn’t contain too much detailed information is likely written by a Green or Yellow. If it has clear information about what outcomes the person wants but not doesn’t include much-supporting information, it is likely a Red. If it is a long, well-structured email packed with detailed information and answers to your questions, it’s likely a Blue.
Determine whether it was drafted more than once.
You can never know this for sure, but you may tell it based on how well-polished the email is. If it has spelling errors and looks as if it has been written spontaneously, it’s probably a Yellow or a Red. Greens and Blues are more likely to agonize over the email and redraft it, so it’s perfectly worded.
