Oh wow, I was under the assumption that Google Apps(Now called G-Suite but I always remember it as the original) kinda gave you a guarantee if sending to other Gmail people and probably other big providers like Microsoft, Yahoo, etc would trust Google more too.

I'm far from shipping from what I'm working on though, but before going live want to get email setup for the main company website and product website for me and future staff, then want to be able to send email's for notifications, password resets, etc and then also have scripts receive and parse emails for replies to put into a database for the support portal part of the product domain but getting ahead of myself. Not sure if the product site would have users to people or just be all scripted sending/receiving while the main site is mostly emails hosted for humans.

I think one strategy would just run a mail server and have a script download the emails to the database and delete them, since doubt many solutions support a more of a webhoook type setup.
