In Craft's documentation for email it says:
Gmail might be a good option depending on your appetite for risk.
But I don't see anything about what the risks are. Is there a risk of getting hacked, or just an increased likelihood of messages not getting through?
I have a small and internal user base, so Gmail might work for me, but I'm trying to make a quick decision and this is making me have to dig for info so I don't make a bad call.
