Continuing the discussion from [Abiding by Amazon SES's "14 emails per second" maximum send rate](https://meta.discourse.org/t/abiding-by-amazon-sess-14-emails-per-second-maximum-send-rate/372896):

I’ve been thinking of switching my SMTP relay to the generous [Emailit plan](https://emailit.com/pricing) of $20 per 100,000 messages, but they’ve recently set a [rate limit of 2 emails per second](https://emailit.com/blog/rate-limit-changes).

Reviewing topics that ask about rate limiting / throttling digests and emails, the only available setting seems to be `DISCOURSE_MAX_DIGESTS_ENQUEUED_PER_30_MINS_PER_SITE`.

I don’t know if I should assume that the value for that is distributed exactly into an X-per-second rate.

And it’s only digests – I’d have to account for other surges like watching-first-post blasts, etc.

With the info I have, it doesn’t feel workable to use an SMTP service with a rate limit. Is there anything reassuring that I’ve missed?
