Simple macro app for Macintosh to just click the 'Delete' button?

Question

Here's a problem I can't seem to figure out.  We use Microsoft Exchange at work, and once or twice a year I get a message that my mail account is almost full.  But deleting old emails is an extremely tedious process; I have to do them either one at a time or in batches of about 15, either of which takes too much time. I do them from the Exchange web app since I use the Mac Mail client.
So I'm looking for a simple way of automating my mouse clicking the "Delete" about 1,000 times in a row.  Something really simple... is there anything built in to the system software that will do this? Or a really SIMPLE and cheap/free app or utility that will do this? (I'd appreciate limiting any answers to solving this immediate problem.. I've been all over the Exchange setting & rules with our system email admin and nothing seems to work.)
Thanks in advance.

You could
1. Copy/Paste the completed 25-step WMD action fifty times into the same workflow:
-- Watch Me Do
-- Watch Me Do
-- Watch Me Do
etc.
OR, better
2. Add a loop action -->
-- Watch Me Do
-- Loop
----  Loop automatically
------ Stop after --50-- times
