We did a Bulk Add of a list of e-mail addresses and 30% of them were not added. This was a straight add with no current addresses to throw duplication errors. I am assuming that Listserv does some validations on the addresses before they are actually added. I can't find documentation on this up to this point and we need to know why the high failure acceptance rate. Can anyone point me to what checking/validation Listserv does on bulk adds.
