We have modified the code a bit to get MM to work on a client site. Seems to be working now, but client wants to know if there is any way to confirm that messages have been received. They sent out over 2,300 messages and and only received 33 responses which they feel is a very low rate based on previous mailings. I have seen the progress bar i.e. '357 of 2,347 sent' and then at the end that '2,347 of 2,347 complete'. Is there any other reporting or tracking available beyond that? Thanks.
