I wrote a new version of MailMergeApp over the weekend. Here’s the press release:
MailMergeApp 1.1 ($10) is an AppleScript Studio application with plugin support, which offer compatibility with any scriptable email program (currently supports Apple’s Mail.app and BareBones’ Mailsmith). This version also adds support for attachments and interface improvements. – Objective Labs
I implemented a plugin environment to allow other scripters to add support for their own email applications. There arent many (any?) other AppleScript Studio programs that have plugins so I’m getting a few emails from curious developers wondering how I pulled it off.
