Database Mail not working from SQL Agent job

I have SQL job setup which has query which sends the query result in e-mail. This query works fine from SSMS and send query result in e-mail using Database Mail. But when I am running this job , job get succeeded but not getting query result in e-mail. 

Running on SQL Server 2008R2 

DB mail profile created and set to default. 

SQL Agent properties using same database default mail profile. 

Any solution for this?

Thanks
