You can select multiple emails at once and do a bulk action on them. You can also export all of them, use something like excel to clean them up, then drop all the emails from blacklist and then import them back again, this time the clean ones.
I have a total of around 3500 emails in my blacklist. I want to remove 400 that I have. I guess there is no way to do this from MW. I will do a delete query from MS access. So removing the 400 emails mw_email_blacklist table sufficient?
I was able to remove it from the blacklist in the backend but in the actual list it still says blacklisted. I tried taking the actual 400 emails and do a bulk action from source but it doesnt give me the option to "confirmed". It only gave me these options. See snap. I tried doing a bulk action and changing it to subscribed but it didnt work either.
