Queuing email lists in specific order to get better open rate

How do you get email lists to send in a specific order for a campaign. I send to my customers that open most quickly first to “warm” my campaign send to be less likely to go to spam. So I need my lists to go in a specific order, but I don’t want to babysit each list as it sends to que the next when it finishes. I just want to load them up.

I don’t think that there is a ‘super simple’ way to do this.
Here’s what I do…

  1. Query the database to generate a list of subscribers that have opened an email.
  2. Generate another list of subscribers that received an email but not opened it.

setup two campaigns:
3. the first one goes to the list described above in #1
4. the second campaign goes to the list described in #2, but set it to start at a later time than the scheduled start time than campaign listed in #3, everything else is the same.

set your system to only send one email at a time (in the config.php file),
This should make the system work the way you want…
