Hi Everyone:

I want to send out a newsletter to my double opt-in members, but have found that the one's using Hotmail end up getting my account and shared server "blacklisted". (which is absolutely the last thing we want!!) I took the trouble to create a hotmail address for myself to discover WHY?? I found that hotmail has designed their email client interface so that it's extremely easier for their users to click on "spam" than it is to "delete" an email message.

This makes it incredibly frustrating as a website owner trying to send out legitimate newsletters to people using hotmail.com ....so, what to do??

I'd like to find a mail list/newsletter program that allows me to delete or suspend sending specific  newsletters by domain. eg "do NOT send to users with "hotmail.com" as an address.

Another option would be to deny users registering using a specific email domain address. eg "hotmail.com"

I use Wordpress.

Can anyone recommend a mail list/newsletter program  or WP Plugin capable of doing the above?
