I use the Send2 Plugin from 4Team Corporation, which allows me to send out individual emails instead of trying to force bulk email.

This works very well for personalized emails to a small group of people.  However, the plugin is not as robust as I would like, causing many reboots if I have too many program open, despite having 8G of RAM on my machine, and often crashing or taking many hours to process just a few thousand emails.  While I have used many different bulk emailers, I really wanted to have something that was a plugin that showed the proper name of my addresses in the To: field and to have a perfect audit of what actually went out in my Sent Items.

So for now I am using Send2 in batches when I have thousands of emails to send out.  When I called their tech support about the problem they remoted in and said I had everything set up fine but that it just wasn’t intended for that many addressees.  So what is the limit?  They didn’t give me one.  I don’t understand how they can sell this as a bulk mailer if it truly isn’t.
