Thankfully, Apple hasn’t forgotten about AppleScript, and neither has Mail.app. That seemed like a good starting point to build the macro I was looking for. I was inspired by this old post by Shawn Blanc (he solves a different problem than mine) to fire up Keyboard Maestro and start playing around with actions thanks to Shawn’s post, I remembered that Keyboard Maestro’s keyboard shortcuts are intercepted by OS X before the system ones – which means, if I were to use the same ⌘R shortcut that Mail uses but I assigned it to my custom action, OS X would launch my action first (instead of the default Mail one). I don’t want to click on menus for accounts and signatures: I want to hit ⌘R and receive a new Reply window with the account and signature I want already set. Apple’s Mail app makes it easy to see all messages sent to all accounts with the unified Inbox, but it makes it surprisingly hard to set default accounts and signatures that should always be treated as, well, default ones. I receive several messages every day to different email addresses, but I always want to reply with the same address and the same signature. As you can guess, I came up with a way to automate the process using AppleScript and (optionally) Keyboard Maestro. But there is one thing I don’t like: Apple’s Mail app and how many clicks it takes to switch between configured accounts and signatures. I have multiple addresses set up, I have my filters and smart folders to automate the process of filing and finding emails, and I’m enjoying the renewed interest of iOS developers in building email apps that solve old problems in new ways. I’m aware of the fact that it’s a common trend to call email a “nightmare” these days, but the truth is – email works for me.
