HI Ben,
I have a list containing about 45000 names, I also split it into 9 sub lists.
This was done to ensure that if there were too many bounces or spam complaints I would have my SES account shut down.
I've sent out some mailing to the sub lists and would now like to merge all these addresses into one list.
In a previous post it was suggested that exporting the active users and importing them into a new list was the way to go, but then how do I stop addresses that were previously removed from getting back in?
Is there a way to combine these lists so that the unsubscribed addresses and bounced addresses are still known?
Thanks
