Ask HN: Freelancers, do you charge for time spent writing emails, etc?

I've been doing freelance work for a client for a few years on an hourly basis. Typically I charge for time spent behind the computer coding, and testing. Usually I would not charge for time reading emails and responding, but I've begun to notice that this time really adds up. Sometimes the client's emails are somewhat garbled, which does not help.

If I were charging per day, this would be less of an issue, but this client is not going to agree to that.

So this question is for freelancers who charge per hour: do you charge for time spent communicating with clients (email, slack, etc)?

I do charge for time spent with reporting or bug-tracking tools like JIRA... I've assumed this is the norm.
