Cannot update Auto Email search criteria

This happens when an auto email was set up using narrowed search results rather than all search results. 

If you select specific listings from the matches of the original search, Matrix will only send auto emails when there is an update on any of those selected listings, rather than based on the criteria used in the search. 

It is not recommended to narrow your search results when setting up an auto email. Instead, once you have finished the search and view the results, go right to the bottom of the screen and click Save> New Auto Email.
