Looking for good mailout/newsletter app - Email Manager Pro or Mail Build?

[jonnya]

I have been looking around for a good newsletter/bulk emailer solution. This is not for spam purposes and I am intrested in commercial products.

A front-runner at the moment is Email Manager Pro - this seems to offer pretty much everything I am looking for and is within budget. All the open source ones I have checked out don't really seem as fully featured as this.

Does anyone have any other suggestions for solutions such as this, both commercial or open source?

The person I am looking into this for currently has around 10,000 contacts with a potential monthly circulation of 100,000 emails a month, so throttling of some sort, robust management and scaleability for the future is very important. I am eager to choose a solution that takes into consideration large distributions like this, and throttles to conserve server resources.

I have also looked into hosted solutions such as Mail Build - although the pricing structure is higher than expected, even with bulk discounts. I'm not sure if my associate will see this as value for money and on-going charges are not so attractive (ignoring hosting with Email Manager Pro).
