I have a mailing list with 788 recipients. When run, the hosting server choked at 520 records because of server limitations. When I run the sent/scheduled mailings report I can generate the delivery summary and can get a .csv of both the intended recipients and the successful deliveries. The list of "intended recipient" contacts has one of two entries in the Delivery Status field: Successful and Unknown.
What I need to do is filter the original recipients list for delivery status=Unknown, but that I can't find a method to accomplish that.
I've solved the host resource limitations issue by using Mailchimp and the Joomla Mailchimp extension. Now I want to resend the email only to the 228 people the server never got to. Is there any way? I have tried custom searches, filters, various reports, but no luck.
Any help would be appreciated. Thanks.
