What do you think about “What do you think?”

“What do you think?” is a weak ending to an email, according to Power Sales Writing: Using Communication to Turn Prospects into Clients by Sue Hershkowitz-Coore.

I said “uh oh” to myself upon reading this because I’ve used this in emails accompanying proposals. Hershkowitz-Coore suggests you encourage your reader “to give you the result you want by offering your opinion and asking for her approval.” She prefers a closing such as “Please let me know which direction you prefer, and with your approval, I’ll move ahead. “

I like the idea of nudging prospects in the right direction, but I also want to show that I’m open to my prospect’s feedback.

There must be a middle ground. What do YOU think?
