After struggling with low open rates in my small lifestyle software business, I decided to go down the rabbit hole that is email deliverability, learned a bunch of things I didn't know even after being in tech for a decade.

We have ideas on how to expand this but first we'd like to know if someone else might find this useful too (we know that this is only a solution for people who get tons of (unsolicited) email). Underlying to all of this is the idea to put…
