People who care about what you do want to hear from you
It’s strange, but we often forget or oversee this point. When you actually create a product or service that people enjoy using, they will be happy to hear from you.
We say this about several YouTube channels we’re subscribed to, various newsletters, and companies who we really care about. We rarely say it when we receive an email blast saying “Time is running out, only 2 days to take advantage of this exclusive offer”. That’s so 2000.
If you can write “I built this and I want to share it with you” to people who actually care, both sides win!
