LOTS_OF_MONEY

This error means that your email is referencing a lot of money. This is a common spam tactic, and it's not a good sign.

Specifically, it triggers on the following kinds of strings:

• $100,000
• one million dollars
• huge sums of pounds

You get the idea. If you're seeing this flag show up, try removing the offending strings from your email and using something more oblique.
