Summary

Submit a transactional email to Keplars’ asynchronous sending endpoint for each input item, using email content or a template. The operation is described as having a 0–5 minute sending window.

Inputs

  • to (required) — Recipient email address; sent as a single-element recipient array.
  • from (required) — Sender email address, which must be verified in Keplars.
  • from_name — Optional sender display name; omitted when empty.
  • subject — Email subject line; declared optional when using a template and omitted when empty.
  • body — HTML or plain-text email content; declared optional when using a template and omitted when empty.
  • template_id — Optional Keplars template ID; included when nonempty.
  • params — Optional template-variable key/value pairs. Converted into an object; later entries overwrite earlier entries with the same key.

Output shape

One JSON response item per input item.

Returns the Keplars API response directly; response fields are not defined in the source, and the node does not wait for delivery confirmation. With Continue On Fail enabled, failed requests return an item containing an error message; otherwise, the node throws an error.
