Your email is probably sitting in a job queue. I would start looking at other options now.

I received this email about an hour ago, so it must be being sent out progressively.

I've not got this either and its not in the admin console. I'm guessing I'll see it in the next couple of days. Think I'll be moving to Zoho mail.

Fortunately, all my Google stuff like Youtube and Google Play purchases are tied to a gmail account. I intentionally didn't use my custom domain for that, as I thought this would happen one day. I didn't expect the free email to last so long though.

I didn't get the email either, or at least not yet, but when I logged on to the admin console the notice was there.

Unless you verify that it's not in the admin console (and continue to verify that it's not there), I'd assume you're subject to it.
