Pick up the phone!
Disadvantages of email:
- the other person can't hear the tone of your voice, or where you are putting stress in the sentence.
- you can't hear the other person's reaction, and pause to clarify
- you can't check of this is a good time for communication
So if at all possible:
- pick up the phone and ask if this is a good time to talk.
- Or send an email and arrange a time to talk.
