Listname/Subset Max Number

The maximum number of recipients to receive this message. This number may be less than the total Recip Count if limited by Maximum Number of Recipients in the Advanced Message Send (1 of 2).

Note that if you select a Maximum Number of Recipients for multiple lists or subsets, the maximum number of recipients will be selected from each list or subset. For example, if you set this number to be 10, and you select three lists to send to, there will be thirty recipients of the message, ten from each list.
