I have a master-detail relationship between Verification Documents and Document Master custom objects,master-detail relationship between Verification Documents and Opportunity.What i am doing through my code is when ValueSet contains 2 values 2 emails are sent.If ValueSet Contains the previous 2 values and if an additional value is added it is sending email to the previous 2 values and new additional value.Is there any possibility of sending a single mail with all the List of values in the email to be sent through code.
