I'm using e-Newsletter in some of my projects and came to some questions about possible functions.
1. Can i customize a template for a letter sent to confirm the subscription?
I've found a double_optin.html script, but i don't know, what tags can i use there. Also, i can't use PHP there (as it is *.html). And most important, all changes in this script wiil be lost on plugin's update.
2. I want to use a static pages to show the messages of successful subcription and unsubscription. Can i do it without hardcoding?
3. When i'm unsubscribing with sidebar widget, i see just a message "you've been unsubscribed" and a button to subscribe (and no options to subscribe again). It seems strange.
