Prioritize Campaigns & Select the number of daily messages
In order to avoid being marked as spam (happened to me in a particular country) or to create an event like "50 winners each day", the users should be able to set the number of messages delivered for each campaign on a daily basis.
e.g. 100 / daily - 3000 receipeints will get the messages in one months times.
However, this creates an issue when there are a lot of scheduled campaigns. The user should be be able to dynamically select the campaign he thinks that they will have the priority, using the available quota for the ones with the highest one.
As an advanced option, the user should be able to set the time window (dates and time of the week) during which the Yamm will deliver. If for any reason a specific window is overloaded, the campaign with the highest priority, is served first.
