Any SAIL function to send Email

I have a scenario like among so many users available in a grid i can assign roles to each user (One at a time).
On updating his role..i need to send a mail to him.
I should do this to all users in the same User Input Task (SAIL Form) without navigating to next node in Process Model;
So i have to do this in SAIL itself.
Is there any SAIL Function (smart service) to send Email?
