I guess is is mail merge. I am on the other hand hesitant to call it Mail::Merge as that rather implies it does mail merge in the word processing sense which isn't true. It's much more generic that that.

And yup, I'm sure you could use it to spam people. But then the same is true of MIME::Lite, Mail::Mailer or the handily named Mail::Bulkmail. If the only application of the module was spam then you might have a point but as this isn't the case I don't see why this is relevant to the question.
