I am unable to.
I've called my CSR and they can't identify the cause of the problem and nobody else has complained about it so far, so a ticket has been opened for me, but since I'm the only guy complaining, "someday" is likely when I'll hear back about it.
I use the email marketing in advance to advise folks when I'm going on vacation, looks like I won't be doing it this time around.
If you have been able to send an email marketing campaign out in the last couple days, please let me know, THX!
