Usage alert

Show measured usage and its limit without changing quotas or subscription state.

This application recipe uses the shared transactional layout. It returns a rendering Effect containing HTML and plain text; it does not submit email or implement the business operation.

import { renderReactEmail } from "@corven/email-sdk/react";
import { transactionalEmailLayout } from "./react-layout.js";

export const usageAlertEmail = (input: { usage: string; limit: string; reviewUrl: string }) =>
  renderReactEmail(
    transactionalEmailLayout({
      heading: "Review your usage",
      preview: "Your account is approaching a usage limit.",
      paragraphs: [
        `Current usage: ${input.usage}. Limit: ${input.limit}.`,
        "Review usage and available options.",
      ],
      action: { href: input.reviewUrl, label: "View usage" },
    }),
  );

Supply authorized data

Compute usage and thresholds in your application and suppress duplicate alerts for the same logical event. Do not infer that sending an alert changes a quota or subscription.

Keep URLs and template inputs under host control. React text escaping is not URL validation or a consent check. Treat the rendered body as private message content.

Send the rendered body

Yield the rendering Effect in your application, then supply its body to Email.send with explicit sender and recipients. Apply ordinary provider validation, submission policy and any required approval. The React integration shows this composition.

These recipes are application examples, not additional template exports from the SDK. Rendering and compilation do not establish delivery or compatibility with every email client.
