So the email doesn't come from "ram chat" actually.  It'll be from 
[email protected] via a salesforce bot type of thing. mine showed up (to me and someone from my dealer was cc'd) about 3 weeks after my order (and about 2 weeks after i got my VIN in a Ram Chat) and it said my VIN and my estimated delivery date to my dealer which was a range of about a week.  And the subject is all caps "A MESSAGE ABOUT YOUR RECENT RAM VEHICLE ORDER"  At this point their estimated delivery window 
could actually hold. And judging by 
@triple_B 's data it's an average of 23 days WS-DL to Massachusetts, which puts it smack in the middle of the week FCA estimated, and i have only been in KZP for a week. But a lot of things get moved around for a lot of reasons to which we aren't privy, so ya nevah know. 
¯\_(ツ)_/¯
