Hi Lily,
As long as you are receiving your "Dailymail Report" each day we should not need to suspect the cron task.
I can point out one problem with your situation: With the "cron-style followups" feature the message is sent once, when it matches the cron, and then the user moves to the next followup in sequence. It is currently not possible to send an email automatically every Monday.
With a cron timing of:
* * 1
Your message should be sent once on the Monday following subscription.
I plan to implement cron-style scheduled messages very soon which will allow you to do what you want.
Please let me know if I can be of further assistance!
Regards, DW
