Why email startups fail

I was engineer 12 at SendGrid and left after IPO and subsequent acquisition by Twilio. Being infrastructure and the backing many email marketing companies, we did really well. Kind of like selling shovels in the gold rush. We struggled more on the product front breaking into the much larger marketing space. Learned a lot there leading and scaling teams and scaling the email infrastructure to support over 8 billion daily sends.

The marketing emails they send will be somewhere between things people actually want to see and mildly annoying. There are plenty of things I subscribe to which are marketing emails I want to see.

"mildly annoying"

That's another name for spam.
