Output shape
A single API response record for the scheduled email.
The operation sends the email scheduling request to the Lettr API; the source excerpt only exposes function signatures, so the exact response fields are not shown.
Examples
Example 1: Schedule an email with raw content
Provide the sender, recipients, subject and HTML or text body, then set Scheduled At to a valid future UTC time.
Example 2: Schedule a templated email
Provide the sender, recipients and Template Slug; optionally provide substitution data and a template version. The template subject can be used when Subject is omitted.
