Resend

Showing 25 of 39 from the live probe.

• Resend Cancel Email

  Cancel a scheduled email before it's sent. Only works on emails with scheduled_at in the future.

• Resend Create API Key

  Create a new API key. Returns the token once — it cannot be retrieved later. Optionally restrict to sending-only access or a specific domain.

• Resend Create Audience

  Create a new contact segment (mailing list). Same resource as Resend segments — add contacts to the segment with the contact upsert tool afterwards.

• Resend Create Contact Property

  Create a custom contact property definition (account-wide). Properties can be set on contacts and used in broadcast templates as {{{property_key}}}. Key and type are immutable after creation.

• Resend Create Event

  Create a custom Resend event definition for automation triggers. Event names cannot start with the reserved resend: prefix.

• Resend Create Template

  Create a reusable email template with HTML content and optional defaults for subject and sender. Templates must be published before use.

• Resend Create Webhook

  Create a webhook to receive real-time notifications for email events. Returns a signing secret for request verification.

• Resend Delete API Key

  Revoke an API key. The token stops working immediately and cannot be recovered.

• Resend Delete Audience

  Delete a contact segment and its segment-scoped contacts. Destructive — do not delete production Newsletter or bundle:* segments.

• Resend Delete Broadcast

  Delete a draft or scheduled broadcast. Sent broadcasts are immutable and cannot be deleted.

• Resend Delete Contact

  Delete a contact. For legacy audiences pass audience_id. For global/segment contacts omit audience_id (uses DELETE /contacts/{contact_id}).

• Resend Delete Domain

  Delete a sending domain from Resend. Sending from that domain will fail until re-added and verified.

• Resend Delete Template

  Delete an email template.

• Resend Delete Webhook

  Delete a webhook endpoint. Resend stops delivering events to that URL.

• Resend Get API Keys

  Get API keys. Pass api_key_id for one row; omit to list key names and IDs (never the secret token).

• Resend Get Automations

  Get Resend Automations. Pass automation_id for the full step graph; omit to list automations (optional status filter).

• Resend Get Broadcasts

  Get broadcast campaigns. Pass broadcast_id for draft/scheduled/sent content and metadata. Omit broadcast_id to list status and send times. For open/click/bounce rates after a send, list sent emails or run the growth/resend pull scripts — not broadcast GET alone.

• Resend Get Contact Properties

  Get all custom contact property definitions (key, type, fallback value).

• Resend Get Contacts

  Get contacts in a Resend segment. Pass segment_id or segment_name to scope the list. Pass contact_id with a segment scope for one row. Set summary_only=true to count targetable subscribers before a broadcast (campaign sizing).

• Resend Get Domains

  Get sending domains. Pass domain_id for verification status and DNS records. Omit domain_id to list all domains. Only verified domains may appear in from addresses.

• Resend Get Emails

  Get sent emails from Resend. Pass email_id for one message (subject, recipients, last_event, timestamps). Omit email_id to list with cursor pagination — use this for broadcast deliverability checks and growth email pulls. Per-recipient open/click stats aggregate from list mode; broadcast GET does not replace list_emails for campaign metrics.

• Resend Get Segments

  List or fetch Resend contact segments (Newsletter, bundle:shopify, etc.). Omit segment_id to list; pass segment_name for an exact name lookup; pass name_prefix=bundle: to discover bundle segments. List responses do not include sizes — set summary_only=true with segment_id, segment_name, or name_prefix to count subscribers (use top_n to rank bundle segments). Resend aliases /audiences to the same IDs; prefer segment_id here.

• Resend Get Templates

  Get email templates. Pass template_id for full HTML and publish status; omit to list templates.

• Resend Get Webhooks

  Get configured webhooks. Pass webhook_id for one endpoint; omit to list all.

• Resend List Automation Runs

  List Resend Automation runs for one workflow. Filter by status to count in-flight runs before nurture cutover.
