I’ve been considering using Amazon SES for my main lists, but I was put off by their limits. Could someone help me understand how that works?

Generally, when I set up and ask for production access, they grant it, wth a limit of 50,000 messages they allow to be sent daily. This limit can go up - you can ask for this just like you ask for production access, or you can see if the limit is raised automatically. I believe SES is most interested in seeing you establish a good reputation with your sending: low bounce rates, lower complaints rates- that sort of thing. 

When you initially ask for production access, they'll ask you for a use case - and judging from that, they'll allow/deny you production access. They're basically taking a chance, based on your use case, if they'll allow you to use the system. They're making sure you're not blatant spammers, so it's good to pepper your use case with things like, "confirmed subscribers", "opt-in", "permissions" - that sort of thing. You still would want to follow that up, and make sure you ARE playing under their rules, as they'll be happy to simply stop allowing you to use their service. I've had this happen myself if my bouncerate is too high - say I mistakenly emailing a coupla thousand fake, "@example.com" addresses from a test list, and they all bounced back. They don't like that ;) 

Dada Mail allows you to send at a rate that stays below your daily quota, as well as the per second rate.  (60 * 60 * 24) * 50,000  = 1.78 messages that can be sent out, per second. I adjust the automatically send rates from time to time. If you have a list of 10,000 subscribers, you don't WANT to send@PROTECTED messages/second, you want to send out as fast as the per second rate is, until everyone has a message sent to it, BUT you also don't want to exhaust your quota for the day - what if you have another mass mailing to send out? 

Also the 24 hour limit is a rolling limit, which complicates (or simplifies) things, depending on how you look it it. 

The 24 hour limit used to default at 10k, rather than 50k, which was a very awkward number, as a lot of people have mailing lists larger than 10k, and having to do a mass mailing that took days really is unappealing.
