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…
