Function Reference

resend_send_email

Sends a single email through Resend's API with support for HTML and plain text bodies. Specify from address, to recipients, subject line, and optional reply-to, CC, and BCC fields. Also supports tags (an array of { name, value } tag objects) and scheduled_at (an ISO 8601 datetime string for scheduled delivery). Returns an email ID that can be used to track delivery status. Ideal for welcome emails, password resets, and order confirmations.

resend_send_batch

Delivers multiple emails in one batch request to Resend, supporting up to 100 messages per call. Each email in the batch can have its own recipients, subject, and content. Significantly more efficient than sending emails individually when you need to notify many users at once. Returns an object with a data array of email ID objects, e.g. { data: [{ id: "..." }] }.

resend_get_email

Fetches the current status and metadata of a previously sent email using its Resend email ID. Returns delivery state (sent, delivered, bounced, complained), timestamps, and recipient information. Useful for building delivery dashboards or triggering follow-up logic based on email outcomes.
