Hi Bentacular,
Did you ever check your log/results file? I just set it up for a smartlist of 20 emails and in steps of 10%. The first 2 hours it went okay.Then it started repeating sending the email to the same people in the second sending. Fortunately I tested it on a sample size for 20 people so I only annoyed 2 people but for whatever reason, it didn't work for me.
Any insights why it started sending emails to people already sent to?
TIA
Patrick
