Hi,
Within the ac_EmailListUsers table there is a column for "LastSendDate". I would think that would be populated when a newsletter is sent out but I sent a newsletter out today and the field remails "0" in all cases. How does this get populated?
Is there any way to see when a user received a newsletter last?
Thanks

I noticed the same thing in my AC 7.0.5 when I did a bulk send a few weeks ago. Some users had values from a previous mass mail back in 2009, so I know it used to update it.

But none of the ac_EmailListUser records updated to reflect the send date of my mailing 2 weeks ago.

I just moved this in our logs
