- Compose on the Emails page, or in Quick Actions on the dashboard, sends a one-off email from a verified domain, for example to test your setup. Under Advanced you can attribute the send to an API key. Compose allows 3 emails per minute and 10 per hour per workspace. See Compose.
- Cancel delivery pulls an accepted, scheduled or attempted email from the queue. Cancellation is best effort: an email that’s already being handed to the recipient’s server may still be delivered. See Cancel an email.
