Sends transactional email — modern developer-friendly alternative to SendGrid/Postmark. Supports React Email JSX rendered server-side or plain HTML, plus batched per-recipient personalisation.

What happens if Resend returns an error?

The run history shows the failed step with its input and the error message Resend returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.

Does Resend Send Email support batch operations?

Run Resend Send Email inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Resend's rate limits.
