I did a bulk subscribe of several hundred thousand people, and the time it took really depending on whether I was using LISTSERV Classic or HPO and how many thread the LSMTP was. I ran tests of bulk subscribes on Classic vs HPO and the difference was drastic (minutes vs hours for the same amount of subscriptions). I've never done a web-based bulk add, but when I sent the email, there was a max capacity of addressses that could be accepted in one email, so I had to split up the list into significantly smaller chunks and add them one at a time. amanda Amanda K.
