> we use Office365 and don't have this issue

I'm not surprised Microsoft's IP range is known by google. Sending from sendgrid, mailchimp, and a few others that send a lot of mail also works. It's when a new player wants to get in the market (or god forbid, an individual with their own nerdy server) where the trouble arises.

To clarify, I wasn't arguing that sending email to Gmail is easy especially if you're using an independent provider that is unknown to Google - which is how you're framing my response as (why?).

I was acknowledging the general issue of dealing with modern email problems and how opaque the underlying systems are.

Postmark requires a minimum of 50K emails a month for a dedicated IP address, and they state that minimum is for quality reasons. You won't get a good enough reputation on your IP without it.

That should give people an estimate of the required volume to get decent delivirability rates to big providers.
