The problem is that I want it to send out duplicates and the Personalized Emailer will not do it. After I use Personalized Emailer Field Inserter the messages that I want to send out are very different, but some of them go to the same address.

    Example data file:

    The message with data_3 fails with a Duplicate recipient error.

    I do not think that Personalized Emailer should see duplicate recipients as an error if any fields have been insterted. At the very least I would like to see an option to ignore the duplicate recipient checking.
