I found out (after creating a trigger) that Mass Email actions do not invoke triggers :( (to my delight!!)

 What I was trying to do is update a date field for all the leads from a Mass Email.  Has any one done any type of workaround similar to this?

fyi:

I found this from the developer guide:

I found this from the developer guide:

Operations That Do Not Invoke Triggers

Triggers are only invoked for data manipulation language (DML) operations that are initiated or processed by the Java

application server. Consequently, some system bulk operations do not currently invoke triggers. Some examples include:

• Cascading delete operations. Records that did not initiate a delete do not cause trigger evaluation.

• Cascading updates of child records that are reparented as a result of a merge operation

• Mass campaign status changes

• Mass division transfers

• Mass address updates

• Mass approval request transfers

• Mass email actions

• Modifying custom field data types

• Renaming or replacing picklists

• Managing price books

Note: Inserts, updates, and deletes on person accounts fire account triggers, not contact triggers.

DOES this mean I cannot do this at all?  Any workarounds that anyone can think of?
