Okay so rather than using my vbulletin forum to send out bulk email to users (Newsletter), how can I use it to generate an email list that I can just copy and paste into my gmail TO line, and then send off?
Under "Users" in the acp there's "Generate Mailing List" which might work for you. But if you paste the entire mailing list in "To" you'll be sending everyone all the email addresses, which you may not want to do.
