I'm sure I've read somewhere how to do this but I am not able to find it at the moment.
I have Postmaster installed, and I am using that to send various emails based on entry creations and status changes.
This all works great, and I have a customised template (with inline css) to produce a nice looking email.
Now I would like to customise the system messages, (i.e new member regs, activation links etc.)
I know there is the Email Notification Templates under the Design>Message Pages option, and these templates produce plain text simple emails.
Is there a way to customise these? Ive read on the Postmaster docs that you can use postmaster for this purpose, but I have been unable to find any more info, or documentation other than to say it can be done.
