What I wanted to do was, delete or import several emails at one time.
If I understand what you're getting at, It seems that what you're looking for is a "List Manager." Something where you send email to a list of addresses.
UBB.threads relies on member accounts which have a username, password, forum settings and preferences tied together. Each of these is required.
There is no way to import a list of email addresses which are not tied to passwords/settings/preferences. They all are required features.
Email List Manager
https://en.wikipedia.org/wiki/Electronic_mailing_listWith an "Email List Manager," you can import a list of email addresses created from another source. At its very basic setting, each email address has nothing else tied to it, except a toggle between "send emails to this address" and "dont send emails to this address."
UBB.threads does a pretty good job for managing and emailing addresses for your UBB.threads members, but... If you have a list of emails completely unrelated to your UBB.threads member base, you can a expand upon your email campaign by adding a List Manager such as one of these:AWeber -

1) Create an email template to use.
2a) Send out emails to your Email List subscribers using that template which mentions that the email was sent from an Email List Manager, and directions of how to unsubscribe from that.
2b) Send out Emails to your UBB.threads members using a slightly altered template, which mentions that the email was sent because they are a current member on your forums, and directions of how to unsubscribe from that. Use the Member Manager directions I posted above, to send these type of emails.
