MySmartMove.com - Provide adverse action letter?

[Brandon C.]

Closed on my first house just over a week ago. Had a couple showings yesterday and one tenant filled out the application. I sent them to MySmartMove and they completed the background and credit check. 

I'm declining them for a number of reasons - particularly due to a terrible credit report. 

My question - Once I select "Decline" on the MySmartMove website, does it send them an adverse action letter or do I still need to do that separately? 

Thanks!
