(Nice plugin. It might be the solution for many of my clients.)
My question is in the topic title.
If emails are not batched, would you put that on the wishlist?
A typical use case for my clients would be to use EAN to send notices to subscribers imported from Constant Contact, MailChimp, etc. That could be hundreds or thousasnds of addresses. Shared-Hosting clients are typically subject to hourly email limits (in the neighborhodd of 400). Hence my question.
