I am trying to understand where to locate the logic to send an email via a contact form in my Angular App (using angular-fullstack MEAN stack from Yeoman).

You need to create a route on the server that you can post form values to from Angular using $http.post. The following lets you enter details in an Angular form. The form is then posted to Node where the req.body values are extracted and added email object. The email is then send by SendGrid.

SERVER.JS

var express = require('express');
var http = require('http');
var bodyParser = require('body-parser');
var dotenv = require('dotenv'); 

dotenv.load(); //load environment variables from .env into ENV (process.env).

var sendgrid_username   = process.env.SENDGRID_USERNAME;
var sendgrid_password   = process.env.SENDGRID_PASSWORD;

var sendgrid   = require('sendgrid')(sendgrid_username, sendgrid_password);
var email      = new sendgrid.Email();

var app = express();
app.use(bodyParser.json()); //needed for req.body
app.set('port', process.env.PORT || 3000);
app.use(express.static(__dirname + '/public')); 

app.post('/email', function(req, res) {
    email.addTo(req.body.to);
    email.setFrom(req.body.from);
    email.setSubject(req.body.subject);
    email.setText(req.body.text);
    email.addHeader('X-Sent-Using', 'SendGrid-API');
    email.addHeader('X-Transport', 'web');

    sendgrid.send(email, function(err, json) {
    if (err) { 
        return res.send("Problem Sending Email!!!!");
    }
        console.log(json);
        res.send("Email Sent OK!!!!");
    });
});
var server = http.createServer(app);
server.listen(app.get('port'), function() {
  console.log('Express server listening on port ' + app.get('port')  ) ;
});

          To
        
        
      
          
          From
        
        
      
          
          Subject
        
        
      
            
        

        
            Submit
        
    
    
       
    

CLIENT SIDE APP.JS

angular.module('myApp', [])

.controller('MainCtrl', function($scope, $http) {

        $scope.submitEmail = function() {

            console.log("TEST");
        //Request
        $http.post('/email', $scope.email) 
        .success(function(data, status) {
            console.log("Sent ok");
        })
        .error(function(data, status) {
            console.log("Error");
        })
    };
});
