Each recipient counts towards your quota. Use `scheduled_at` to send later (up to 30 days ahead). Pass `tenant_id` to send on behalf of a tenant (not needed when the `from` domain belongs to one). Fails with `422` if `tenant_id` conflicts with the domain's tenant, `403 sending_paused` if the tenant is paused and `429 daily_quota_exceeded` if it reached its daily cap. `from` must be on a verified domain (e.g. "Acme "); call list_domains to find one. Provide `html`, `text` or both. Send to delivered@test.spacepost.dev (or bounced@ / complained@) to test without sending real mail. Delivered email cannot be recalled: confirm recipients and content with the user when unsure. Pass `idempotency_key` when retrying so the email is not sent twice. Request body: Either `html` or `text` is required. `reply_to` is also accepted as `replyTo` and `scheduled_at` as `scheduledAt`. Works with a `sending_access` or `full_access` API key. API: `POST /emails` (operationId `sendEmail`, Emails). ``` ### `update_broadcast` - The name "update_broadcast" says "update": a word for a change. - The name "update_broadcast" also says "broadcast": a word for sending, and what is sent cannot be taken back. - Tag outbound: The name "update_broadcast" says "broadcast": it sends or publishes something to other people.
