When seeking information from busy people via email the little things matter. Quick, minor tip: use a question mark if you’re asking a question. Compare the following cases:
Case A: Do you have any feedback for me on this point?
Case B: I would be interested in hearing your feedback on this point.
The question mark in A will yield a higher response than the passive Case B. Another example I learned when doing sales:
Case A: Will you be in town on Nov 5th for a meeting?
Case B: If you’re in town on Nov 5th, I would love to meet.
Again, I think the question mark yields a higher response. When I receive an email from someone I don’t know, I immediately search for the question mark.
Bottom Line: If you want a response, use question marks. Present active not passive questions!
