By default you get an email at **25%, 50%, 75%, and 100%** of your allowance. ## How they work Each alert is a threshold — a percentage of your [monthly credit allowance](/documentation/billing/credits) — and a recipient email address. We check your usage across all regions every few minutes, and the moment your consumption crosses a threshold, we email the recipient. * **Each threshold fires once per month.** Once the 50% email has gone out, it won't fire again until the allowance resets. * **The counters reset at the start of each calendar month.** All four alerts re-arm on the 1st, so you get the full 25 / 50 / 75 / 100% sequence again against the new month's usage. * **Only crossed thresholds fire.** If a sudden spike takes you from 40% to 80% between two checks, both the 50% and 75% alerts fire together. ## What the email looks like The email comes from **Composo Alerts** (`alerts@composo.ai`), with the subject **Composo API Usage**. It names the domain, how many credits you've consumed against your allowance, the percentage, and which threshold you crossed — plus a link to your [`/usage` page](https://platform.composo.ai/usage) for the full breakdown: ``` acme.com has used 375.00 of 500.00 monthly credits (75.0%), crossing your 75% usage alert threshold. See your full usage breakdown on the platform: https://platform.composo.ai/usage ``` ## Alerts don't block requests Usage alerts are notifications, not limits. Crossing 100% — or going over it — doesn't throttle or stop your evaluation calls; they keep succeeding, and your usage simply shows an overage. See [What happens if you go over](/documentation/billing/credits#what-happens-if-you-go-over). ## Changing recipients or thresholds Want alerts sent somewhere else, extra thresholds, or a different set of recipients?
