Best direct mailing solution, & the best relay/proxy solutions.
 

On the market today.

Who would you go with for your can-spam compliant opt-in lists?

Aside from Robomail which is clearly superior, but too pricey for me.

http://www.spammerware.com is pretty good mailer.

Lyris for a powerful full service application, unless you have the budget to buy or build a custom solution ...

But Lyris is even more expensive than Robomail :winkwink:
