Close faster. Don't do any of this "custom code or helped with integration" bullshit unless they're paying you for it. Develop intuition. That's about all you can do. 75 emails is... A lot without making a sale. Fwiw I'll usually get 1-3 emails asking what client wants, hopefully a phone call, I write a proposal and send it over, I wait a few days and follow up asking what they think. Maybe the want to negotiate terms or whatever, that's 1-3 more emails and maybe another call. All in all <10 emails, 2 calls max, and I either have a sale or I say thanks and feel free to contact me in the future if they're interested in this or other work. I never work for free without getting paid for something first. I won't do coding tests, I won't write code, I won't figure out a problem. I will give them expert advice if I can and if it will help them see the value of my work. However say I've had a client pay for a job before and they have a small ask - I'll probably do it for free if it's 2 or less hours one time. And intuition - I mean that's hard but you gotta be able to read people. Know when they're kicking tires, know when they're in over their head or out of their element, know when they don't have the Auth to get a request filled.
