The only reason I use Spark over Apple Mail is that I get push notifications as I receive emails on my Gmail account.

Unless you’re a paying Gmail customer, you can’t get push, only pull email.

With Spark you now don’t get priority email, whatever that is, so why would I stay? Back to Apple mail it is

Gmail's bad/nonstandard IMAP is one of the reasons my Gmail account has long been relegated to a spam bucket address. Anything important is going to either Fastmail with a custom domain or iCloud mail.
