XML Publisher-Emails not Going

The bursting process working properly with below configuration however email not going and not getting error message. Output also showing PDF document properly and it submit request for XDOBURSTREP and it complete also successfully but why email not reaching?

Question -> Does bursting process depends on the workflow process? Means emails going through workflow process or BURSTING IS INDEPENDENT OF WOKFLOW?
