I'm working on a way to limit how many posts that will be public at one time. It would be awesome if I could have postie check every 10 minutes for 1 (or 2) emails then post it. At current I have about 6-7 posts coming into my email every 30 minutes and a plugin to auto post everything to my social media sites. So I get 6-7 posts on my other sites because of this. Having more flexibility with this could help spread out the posts for me.
