POST endpoints
send_email
Send a transactional email with 'from' (verified domain), 'to' (string or array), 'subject', and 'html' or 'text' body. Supports 'cc', 'bcc', 'reply_to', 'headers' (custom), and 'tags' [{name, value}] for tracking. Returns email ID for status polling.
https://api.resend.com/emails
add_contact
Add a contact to an audience by audience_id. Pass 'email' (required), 'first_name', 'last_name', and 'unsubscribed' (boolean). Returns contact ID. Duplicate emails are silently merged.
https://api.resend.com/audiences/{audience_id}/contacts
send_batch
Send up to 100 emails in one API call. Each entry in the array uses the same shape as send_email (from, to, subject, html). Returns array of email IDs. More efficient than individual sends for bulk notifications.
https://api.resend.com/emails/batch
GET endpoints
get_email
Get email delivery status by ID. Returns 'from', 'to', 'subject', 'created_at', and 'last_event' (delivered/bounced/complained/opened/clicked). Use to verify delivery or debug bounce issues.
https://api.resend.com/emails/{email_id}
list_domains
List verified sending domains with ID, name, status (verified/pending/not_started), DNS records needed (SPF, DKIM, DMARC), and created_at. Domains must be verified before sending.
https://api.resend.com/domains
list_audiences
List all audiences (contact lists) with ID, name, and created_at. Use audience ID to manage contacts or send batch emails to a segment.
