Yes. You can do it very easily. First use an “Input Dialog” activity and store the output to a String variable. Then use your desired “Send Mail” activity and pass that variable to the Receiver’s email address field.
This is very simple you just need to provide input dialog box activity to create a prompt so that user can type their email id at run time and in send mail activity provide the To address as output created in Input dialog box.
