I don't think you can e-mail objects as they are i.e. a query as a query. You can e-mail the results by using the SendObject action.
If you need to e-mail the structure of the query then, providing your recipient has exactly the same .mdb as you, why not import the query into a new blank database and e-mail that. All they would have to do at the other end is to import that query into their copy of your .mdb
If it is the OUTPUT of a query, than Robert Dunstan has it right, but if it is the query itself, you can just Email the SQL and they can paste it in a query. Of course they have to have the same table structure/names etc.
