Inquiring about Email Notification Failure and Pricing for Netlify Pro Version

I have a question regardings the pro version. We’re considering about it
We’re currently managing two websites on Netlify. However, when the Netlify build failed, we didn’t receive email notifications. May I inquire if upgrading to the pro version would include both sites for the $19/month, or only one?

@vinhliverpool I’m not sure what you’re referring to regarding build failure & email notifications, there should be no difference in that behavior between a Starter Plan and a Pro Plan.

Number of sites wise, as shown in the information on the Pricing Page, the Pro plan supports up to 500 sites, but may of course cost more than the $19 depending on the number of members/git contributors and various usage/overage pricing:

Thanks for letting me know!
