We have 3 Campaigns
2 with each about 900 email addresses of which 2/3rd belong to both of the campaigns
The 3rd Campaign is sent out as an Invite Campaign with an email address list of 1600 addresses partly the same as the address list of the other 2 Campaigns.
Now I have Blacklisted by Invite Plugin for all the email addresses which the 3 Campaigns have in common and are not confirmed.
The 2 other Campains had no Blacklisted users when I started the 3rd campaign.
How can I undo the Blacklisted by Invite Plugin for the 2 affected campaigns?
