  take: 20,
  order: "desc",
  eventTypes: ["EMAIL_OPENED", "EMAIL_CLICKED"],
});

Campaigns

// List with pagination
const { campaigns, total, pageCount } = await lumail.campaigns.list({
  status: "DRAFT",
  page: 1,
  limit: 20,

});

const { qstashMessageId } = await lumail.emails.send({
  to: "user@example.com",
  from: "noreply@yourdomain.com",
  subject: "Order Confirmation",
  content: "Your order is confirmed.",
  contentType: "MARKDOWN", // "MARKDOWN" | "HTML" | "TIPTAP"

await lumail.events.create({

Tools (V2 API)

// List all tools
const { tools, grouped } = await lumail.tools.list();

// Run a tool with typed response
const result = await lumail.tools.run<{ subscribers: unknown[] }>(
  "list_subscribers",
  { limit: 10 },
);

Error Handling

The SDK throws typed errors - catch specific error types:

import {
  Lumail,
  LumailAuthenticationError,
  LumailNotFoundError,
  LumailRateLimitError,
  LumailValidationError,
  LumailPaymentRequiredError,
} from "@/lib/lumail-sdk";

try {
  await lumail.subscribers.get("unknown@example.com");
} catch (error) {
  if (error instanceof LumailNotFoundError) {
    // 404 - subscriber not found
  } else if (error instanceof LumailAuthenticationError) {
    // 401 - invalid API key
  } else if (error instanceof LumailRateLimitError) {
    // 429 - rate limited, error.retryAfter has delay in ms
  } else if (error instanceof LumailPaymentRequiredError) {
    // 402 - plan limit reached
  } else if (error instanceof LumailValidationError) {
    // 400 - invalid request
  }
}

Retry Behavior

• GET/PUT/DELETE requests retry up to 3 times on network errors and 429s
• POST/PATCH requests do NOT retry (prevents duplicate subscribers/emails)
• Retry delays: 1s, 2s, 4s (exponential backoff)
• Respects Retry-After header from rate limit responses
• Default timeout: 30s per request
