That's actually fairly sophisticated (bordering on overkill, but then again it is overkill with a marketing purpose given that they're analytics folks...)

If I were going to do it:

1) Is my book about sadomasochism? If "no", I would reconsider "Submit" as button copy. People like "Get My Free X" a lot more, which leads into...

2) "Join the conversation" sounds like something that only a marketing person would love. If you want to offer something to convince people to join your list -- and you do! -- promise them immediate value from it. There has to be an early chapter you can give away for free. If your publishers are too 19th century to cotton to that, a) they should be fired but b) you can produce something short & actionable which is spiritually aligned with the book and then give that away.

3) Microcopy to the general effect of "We won't spam you" pretty much invariably works. It's also a good idea to set expectations as to what kind of email they'll be getting and how frequently.

Took me a few beats to get #1, but point well expressed :)
