Please Help! Newsletter!

I am currently running sendblaster 2 to merge all my gathered subscribers and enables wysiwyg email template setup. This looks at my subscriber in box regularly for any emails that contain Subscribe in the subject line and automatically send out a response. Can i use the newsletter addon in CS-Cart that would enable users to simply enter their email and then have CS-Cart send an email to a specified address with the subject line being “Subscribe”

Any help would really be appreciated. Or a simple way of doing the same job hehe

Effectively I would like a second contact us with a specified subject line, I have created a form which asks for the email address etc but there is no where there to specify what the subject line will be.
