🚨

Action Plan: What To Do If Nearing Daily Limits (>80%)

1. Understand the Quota Cap: Personal Gmail accounts (@gmail.com) enforce a strict 500 messages per 24 hours rolling limit. Official Google Workspace domains (@pythagorastoolbox.com) allow 2,000 messages per 24 hours.

2. Instant 30-Second Failover (Zero App Rebuild): If usage surges near 400+ messages today:

Create a free account on Resend.com (gives 3,000 free emails/month, 100/day) or Brevo.com (gives 300 free emails/day).
Generate an API key and paste it into the API Key field above.
Switch the Active Email Delivery Provider dropdown to Resend REST API or Brevo REST API.
Click Save & Sync to Field Tablets.

3. Automatic Field Propagation: Every Android tablet in the field checks Firestore every 5 minutes. The tablets will immediately route all subsequent verification requests through your new provider without requiring any app update or Play Store re-approval.
