Thanks for sharing this. Looks really useful since I'm working on a drip email campaign. Have saved it in pocket for reading later since its so long! I've also signed up to GetDrip recently, its pretty good to use for drip marketing.
It's one thing to have the Google Brigade defend their corporate parent's every move on HN. But these kinds of posts bring out the hucksters to plug their products, and that's (arguably) even worse.<p>Nothing against the content itself - it looks like a great article - it's the shilling in the comment section that ruins it.
