Mass emailing.

is there software that can be added on to do mass emailing.  I need to break down my list and send on times, since my host server will only allow me to mail out 80 email an hour. 

Once you have smaller distribution lists, you can use eM Client’s delayed send feature.

Another option is to add the recipients to a single email as BCC, then it will only count as one email with some providers, but you won’t get the customization that you get with the mass mail feature.
