Hi Stefano,
We miss the bounces tab! Just to let you know - it was much easier to use than the advanced import plugin.
The built in import mechanism (.../wp-admin/admin.php?page=newsletter_users_import) is easier to use and has the same features except field mapping.
Can we get the bounces tab back, please? The bounces tab and built-in import allow to paste e-mail addresses - that ability is in my opinion great!
