I love getting charged $75 for emails that just say “OK”

I do consulting, but not as a developer, more business growth/strategy.

I tell all my clients, you are not paying for my time spent on a specific task, you are paying for access to my 25+ years of experience, learnings, and contacts.

An email that just says "OK" might be the net result of a set of experiences and knowledge that would take the client 2 weeks and $2,000 to obtain on their own. $75 would therefore be a bargain.

I too delude myself into believing an "OK" from me is worth $75.

You obviously haven't been the decision maker for anything remotely important.

Keep fooling yourself.

You’re underselling it. You’ll get a message saying:

“OK”

THE CONTENT OF THIS EMAIL IS CONFIDENTIAL AND INTENDED FOR THE RECIPIENT SPECIFIED IN MESSAGE ONLY. IT IS STRICTLY FORBIDDEN…

I've always thought that was weird. What is the underlying reason do you think? I get 6 minute phone calls, but to then pivot to another 6 minute+ task is too granular

Suspect 6 minutes being increment has more to do with being 1/10 of an hour (easy to calculate rate) & and as fine-grained as you can get without being so obnoxious you can't track.
