If you don’t have any comment box it’s hard to give you any feedback.
"Why is nobody calling to invite me to parties", says man who unplugged his phone.
Edit: Ok, I'm old. For younger people, pretend I said "turned off his phone".
This reminds me of a friend of mine who in a B2B setting contacted a potential vendor by filling in a form, with his email and phone number as contact details. Instead of emailing or calling back, this vendor continued the conversation by tracking down my friend on LinkedIn and messaging him there! They already had the email and phone number from their form.
I'm also not super impressed by the consulting gig's "Johnny Holton" reference talking about Jake's "engineering excellence". A google search says Johnny Holton is an American hand egg player.
If I were a potential client going in cold then this would not fill me with confidence in his attention to detail.

I put my email address on these things. All spammers already have it anyway. I get some feedback.
Or a normal web form with a captcha will create minimal spam. Certainly sufficient for someone not famous.
Or you can have a google form. Either with or without google verifying the senders email address.
It works for static sites, you just need to embed their script, and spam and moderation would be handled by GitHub.
