Your company upgraded to an enterprise account, and took you along with it! When a company buys a premium subscription they whitelist email domains (.e.g @doodle.com).

That’s why you may have seen all those previously blocked Premium features become available. If you’re curious about your new Premium account you can dig a little deeper here.
