We are planing to use the Firebase Authentication Service instead a own OIDC Provider. As i could read, Firebase Authentication has a Limit for sending address verifications emails by 1.000 or 10.000 per day (based on the subscription).
But what happens when your App/Site hits this limit, is there a way to bypass them - for example by getting billed - or are the following users unable to create a account because they didn't get the verification email.
Could we add our own smtp provider to bypass that limits?
