Simple suggestions for an appointment...
We could meet on Friday at 2 p.m.
Are you available on Monday at 10 a.m.?
...can become quite cumbersome when many possible dates have to be given due to one person being busy.
How could I shorten several suggestions in a formal mail? I have seen this approach:
Could we meet tomorrow (2-4pm), Friday (12-6pm), ...
...but I am unsure whether this would be correct, especially in formal writing?
What is the usual practice to give multiple suggestions for an appointment while keeping the writing as short as possible?
