Sending an unlimited number of emails in an Ionic project with Angular

[ionicsiva]

I want to implement the ability to send an unlimited number of emails in an Ionic project with Angular, I've tried to send unlimited emails, but they are not being delivered. I've encountered a error in the "FirebaseError: Firebase: Exceeded daily quota for email sign-in. (auth/quota-exceeded), This is the code for sending email functionality. Please review it.

import { Injectable } from '@angular/core';
import { AngularFireAuth } from '@angular/fire/compat/auth';
import firebase from 'firebase/compat/app';

@Injectable({
providedIn: 'root'
})
export class AuthService {

constructor(private fireAuth: AngularFireAuth) {}
public sendAuthEmail(email: string) {
const actionCodeSettings = {
url: 'https://exampleurl.com',
handleCodeInApp: true
};

return new Promise<any>((resolve, reject) => {
  this.fireAuth.sendSignInLinkToEmail(email, actionCodeSettings)
    .then(() => {
      resolve('Email link sent successfully'); 
    })
    .catch((error) => {
      console.error(error);
      reject('Email link not sent');
    });
});

}

public async enterVerificationCode(email: string, emailLink: string) {
return new Promise((resolve, reject) => {

  if (!firebase.auth().isSignInWithEmailLink(emailLink)) {
    reject('Invalid email link');
    return;
  }

  firebase.auth().signInWithEmailLink(email, emailLink)
    .then((userCredential) => {
      const user = userCredential.user;
      resolve(user);
    })
    .catch((error) => {
      console.error(error);
      reject('Error confirming email link');
    });
});

}
}
