I also would really like to see this feature
I have a few "Canned Email Response" templates for common business replies to inquiries. Currently I store them elsewhere (Evernote) and have to copy & paste them in. Auto-reply doesn't work because they need to be customized. I would LOVE to have templates to choose from within Airmail when replying!
Is there any updates on this?
GOOD idea ... Like Spark options
