This is probably a good time to ask about how people handle transactional email generally.<p>I had a play with Mailgun a while back (and others, Mailgun felt nicest to me) but there was a feature that seemed to be missing from them all.<p>How do you handle rules between outgoing emails?<p>For example, say there's an email that gets sent out on a user action, but you only want to send it out once a day. It feels to me like I should be able to set rules within Mailgun to say, only send out this email every x minutes, or, don't allow it to go out if another type of email has gone out before etc.<p>Is there a way of dealing with that? At the moment we have to put all those rules into our app, and it seems like something the app shouldn't have to deal with.
