Yes, GMail is absolutely terrible on that regard. I've been missing out on project mails from an UN organisation I have been working and exchanging emails with because of their aggressive and useless filters.
For me privately, switching to a better provider solved that.
But having >25% GMail customers and always landing in Spam is horrible. Pretty much any other provider likes our mail server, but GMail always says spam.
Then you're going double opt-ins but customers still mark mails as spam because unsubscribing is too hard. Thanks for nothing.
There is actually an industry in gaming GMails spam filter to somehow get into the inbox: some offer automated replies and unmarking spam, some manually run hundreds of mailboxes and don't do anything else all day than unmarking mails as spam.
