Email form responses, but do not include blank responses - email

Question

So I am using a script i found on line to send an email everytime a Google Form is completed, which includes the data in the form via a Google Sheet.
function sendFormByEmail(e)
{
var email = “email#address.com”;
var s = SpreadsheetApp.getActiveSheet();
var headers = s.getRange(1,1,1,s.getLastColumn()).getValues()[0];
var message = "A new travel request has been submitted.";
var subject = "New Travel Justification Request: ";
for(var i in headers)
message += headers[i] + ': '+ e.namedValues[headers[i]].toString() + "\n\n";
subject += e.namedValues[headers[2]].toString() + " - starts " + e.namedValues[headers[15]].toString();
MailApp.sendEmail(email, subject, message);
// Based off of a script originally posted by Amit Agarwal - www.labnol.org
// Credit to Henrique Abreu for fixing the sort order
}
It works well, but I want it to exclude the headers for empty cells, as not all parts of the form require completion.
I know very little, so all help is appreciated.

I have updated the original Google Form script to not include fields that are empty. You can add a simple condition in the for loop:
for(var i in headers) {
if ( e.namedValues[headers[i]].toString() != "") {
message += headers[i] + ': '+ e.namedValues[headers[i]].toString() + "\n\n";
}
}
