try changing the time between emails.in the universal email wizard, click the To button to go to the advanced to screen and Increase the Wait Between sending emails option.

I'm having a similar problem with clients receiving duplicate emails. I'm sending about 250 emails via looped option using a SQL table of email addresses. Each address receives two emails. I changed my timing settings to this:
$BurstSize = 25;
$BurstTime = 1;
$WaitTime = 2;
It used to be 50,1,1 respectively. Also, either setting seems to work ok with short email lists. Help. Thanks. Files attached.
