Two campaings simultaneously

Is it possible to have two campaigns sending mail simultaneously?

yes, you need the following in your config.php file:

# max messages to process
# if there are multiple messages in the queue, set a maximum to work on
define('MAX_PROCESS_MESSAGE', 999);

# process parallel
# if there are multiple messages in the queue, divide the max batch across them
# instead of sending them one by one.
# this only works if you use batch processing. It will divide the batch between the
# campaigns that need sending.

The PROCESSCAMPAIGNS_PARALLEL tells the system to send more than one campaign at a time, and the MAX_PROCESS_MESSAGE tells the system how many to send at a time.

Note that your batch settings will be split between the messages, i.e. if you are sending 100/hr, and sending 2 campaigns, the system will send 50 messages from campaign 1, and 50 messages from campaign 2 in one hour.

Thanks. I will try and let you know how it went.
