Ok ... your email client is weird in how it put's html in, but that's a
different subject. The stack trace indicates that logic:iterate can't
find the collection you stored in "usersList". You could wrap the whole
table in logic:present tag and then have some error message in a
logic:notPresent tag to better diagnose what's going on. Are you sure
your action is being executed?
