Frequencies 

There are four types of frequencies specified in the e-Alert service. Subscribers can subscribe themselves ans specify at which frequency they will receive emails.

Cron jobs

To send the emails to the subscribers, some cron jobs have to be specified. The values that are specified for each cron job specify the time and frequency that mails will be send for each frequency. Below is an overview of the default values which are provided.
