On my web site I have a contact page. On that page you'll find an email address: that email address routes to the inbox I use every day. If you email that address then your mail appears without delay.
And every day I receive a lot of unsolicited, non-spam mail. These mails contain suggestions for The Geek Atlas, questions about GNU Make, people asking where they can find some article I wrote n years ago, requests for assistance getting shimmer working correctly, requests for bits of source code or other data that I hold, and much, much more.
I try to answer all my mail within 24 hours.
And here's where I want to rant: most people are grateful when I reply to them, but there are some who simply don't bother to reply. Would it kill you to hit Reply and just enter even a one word "Thanks"? Seriously, I've often gone out of my way to get find something for people to hear nothing back.
Perhaps, it's because I'm British that I expect a bit of politesse, but it cost me (unpaid) time to answer your query, use just a few seconds of your time and say thanks. That's all the compensation I ask for.
