To correct the syntax of your query:
Delete sp
FROM (Select *,
			Row_NUmber() over (partition by EmailAddress order by CreationTime Desc) rn 
		from OpenClickThru where EmailAddress is Not NULL
	) sp
Where sp.rn > 1

Did you run the query as is? Maybe you left out the word "FROM" since I get the same error without it.

Original query not missing "FROM", missing "SP" before the "FROM". :>)
