How to communicate at work: it's not how you talk to your friends, but it's not stiff or robotic either.
Texting your friends and emailing your manager call for two different voices. Professional language is clear, complete, and leaves out slang, texting abbreviations, and casual filler.
"hey! can't make the mtg tmrw lol, swamped rn. lmk what i missed"
"Hi [Name], I hope you're doing well! I won't be able to make tomorrow's meeting due to a scheduling conflict. Could you send me a quick summary afterward? Thank you!"
"yo idk if this is right, can u check it real quick"
"Hi [Name], I hope you're doing well. I wanted to double check this before moving forward, could you take a look when you get a chance?"
Every email starts with a greeting: "Hi [Name]," or "Hello [Name] and [Name],". A short, warm line like "I hope you're doing well" or "I hope you had a good weekend" is a great way to lead in before you get to your point.
Say why you're writing in the first sentence. Don't bury it.
Give the context needed, and be specific about what you need from them (a decision, a file, an answer by a certain date).
"Thanks," "Best," or "Looking forward to hearing from you," followed by your name.
