That's flattering, but not accurate. I am by no means the world's leading expert on email marketing, nor even lifecycle email marketing or drip marketing, both of which I am legitimately good at. (I have no results to write home about for sending newsletters, and sending newsletters is a multi-billion dollar industry.)

I do write about this a wee bit in a fashion which is easy for engineers/startup-ers to understand. I also do it for clients on a fairly consistent basis. I will be covering it in more detail in the future. (Sign up for my mailing list. I mean that in both the ironic and unironic senses.)
