To send transactional emails via the Resend API with retries, provide your RESEND_API_KEY to dispatch messages while the system automatically handles common API errors using exponential backoff. This ensures reliable delivery without writing custom retry boilerplate.

Idempotency in batch email sending prevents duplicate message delivery by assigning unique identifiers to each chunk. If a network timeout occurs during a bulk send, the system safely retries the specific failed chunk without resending successfully delivered emails.

You do not need a webhook secret to send emails, but providing an optional RESEND_WEBHOOK_SECRET enables webhook-ready delivery tracking. This allows you to monitor delivery statuses and handle errors for robust, real-time email workflows.

Yes, you can use batch email sending for bulk message delivery without writing boilerplate code. By providing your RESEND_API_KEY, the system manages per-chunk idempotency and retries natively, ensuring your bulk sends scale easily and reliably.

Transactional email API requests often fail due to rate limits or transient network issues. This approach handles common API errors with exponential backoff, automatically retrying failed requests with increasing delays to ensure successful delivery without manual intervention.
