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.

Hi HN :) really excited to share this with you. The one thing AI reliably does is generate noise. Half the tools I see launch are just machines for producing more noise across more channels. And people are starting to see this in the form of emails in their inboxes as spam filters are struggling. There used to be a useful signal in email: the effort a sender put into customizing a message was a rough proxy for how relevant it actually was. AI killed that.
