# Account Quotas and Limits

Mailofly enforces quotas to ensure infrastructure stability, protect IP reputations, and prevent accidental burst sending.

## Handling Over-Quota Requests

* **Rate Limit (HTTP 429)**: If your application exceeds the per-second API burst rate, Mailofly returns a `429 Too Many Requests` header with a `Retry-After` timestamp. Use an exponential backoff retry mechanism.
* **Monthly Quota Exceeded**: You will receive email notifications when you reach 80% and 100% of your plan allowance. You can enable automatic overage protection in **Billing Settings** to avoid delivery interruption.
