We automatically adapt to your Worker as you send. Generally speaking, if you are sending only a few messages per hour, you won’t trigger any adaptive rate limits at all. If you want to blast to a huge list, then keeping your initial sending rate under about 1,000 per hour will ensure we don’t slow you down. As a general rule, if you get a rate limiting error response from our API, just pause for a bit and then keep going, backing off until your mail is accepted again.
