Suggested Query parameters for email:

Avoid combining more than 3 different Queries, if there are more than 10 total rows of criteria. 

If you need to send an email out with more than 10 rows of criteria, duplicate your mailing list and send separately.  

Also try to combine criteria when possible.  For example, do not add Email Address = and Email Address = as separate criteria.  Instead choose Email Address Is One Of and enter both addresses in the same criteria set.
