I am very sorry to report there are simply too many privacy/usability weaknesses and bugs to use this properly - at least on WP 3.5.1.
- Ensure subscription and un-subscription work reliably.
- Make sure unsubscribed E-mail addresses are actually removed and re-subscribing is possible
- Provide useful welcome and goodbye message on opt-in/out landing page (not just the unsubscribe function)
- The confirmation E-mails must support adding a signature in the right place, adding subscriber name and Email address, not just showing the default admin email
- Don't reset everything when deactivating plugin
- Dashboard usability...
- English language...
Sorry to be so harsh...Obviously, I'd much rather this were to work as promised. Would have been happy to donate a few bucks too. Now hoping for updates...
