What is it about the email that makes you think you have to respond soon? Is it the culture at the company around email?
I work at a non-technology Fortune 500 in the IT dept. (I work remote, too) and the general expectation is that we check our email 2-4 times a day. Occasionally I go a day going through my inbox once all day, and it has never been a problem.
I suppose it is a company culture issue?
