Reporting: UE v.4
There are numerous companies out there that have created entirely new online businesses offering internet mass email mailing services, Constant Contact, Topica, etc.
I have been able to utilize UE v.4 for the past 5 months successfully sending over 12,000 messages in 5hrs for (5) separate monthly newsletters (60,000+ messages in 5 months!).
The step that I'm missing is reporting. UE v.4 records (success/fail) data in the email_log table. This data is handy, but I'm looking for data on Clicks, Opens, etc... Which is stored on the server log files.
I wish there was a WA solution that would simplify the laborious task of collecting this data and producing a sexy graphical report. Google Analytics imports would be really cool too.
