  • 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. If provided alongside subject or body, all supplied fields are sent.
  • params — Optional key-value pairs for template variables. Converted to an object, with later values replacing earlier values for duplicate keys.
