I used the shortcode to add a customised 'Unsubscribe' link, but it actually says 'Subscribe' in the newsletter (it is sent to subscribers, not a preview). The link does let me unsubscribe, but the wording is wrong. How can I fix this (or is it in the plugin code)?
Also: If I'm using a shortcode, how can I remove the built-in Unsubscribe line? I can blank the text but the line / space where it would be is still generated, so the formatting looks a little strange, with a large gap between the end of the newsletter and the post address.
