NewEmail API
- Send an email: each recipient gets its own email ID. Schedule with an ISO 8601 date, a Unix timestamp or natural language such as “tomorrow at 9am”, and prevent duplicates with the
Idempotency-Keyheader. - Retrieve an email: status, headers, content, tracking settings and metadata.
- Update a scheduled email: change the send time up to 3 minutes before it’s due.
- Cancel an email: stop a scheduled or queued email.
Every send response includes ratelimit-* headers. See Rate limits.
