Send Email When New Rows Are Added (Google App Script & Google Sheets) - google-apps-script

Question

I have a google sheet containing 4 columns; title, url, published date and email sent (in that exact order).
When new rows are added to the sheet i want to execute a google script that will look through the 'email sent' column to see if an email has been sent and if not send an email containing the new rows and update the associated row(s) with a yes.
My current code is only getting the first row and nothing else.
Thanks in advance,
Mark
(see my current code below)
function sendemail() {
//setup function
var ActiveSheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
var StartRow = 2;
var RowRange = ActiveSheet.getLastRow() - StartRow + 1;
var WholeRange = ActiveSheet.getRange(StartRow,1,RowRange,4);
var AllValues = WholeRange.getValues();
//iterate loop
for (i in AllValues) {
//set current row
var CurrentRow = AllValues[i];
//set subject line
var Subject = "New Content on IG.com";
//set HTML template for information
var message =
"<p><b>Title: </b>" + CurrentRow[1] + "</p>" +
"<p><b>Article: </b>" + CurrentRow[2] + "</p>" +
"<p><b>Published Date: </b>" + CurrentRow[3] + "</p>";
//define column to check if sent
var EmailSent = CurrentRow[4];
//define who to send grants to
var SendTo = "TEST#gmail.com";
//if row has not been sent, then...
if (EmailSent != "Yes") {
//set the row to look at
var setRow = parseInt(i) + StartRow;
//mark row as "sent"
ActiveSheet.getRange(setRow, 4).setValue("Yes");
//send the actual email
MailApp.sendEmail({
to: SendTo,
cc: "",
subject: Subject,
htmlBody: message,
});
}
}
}

Try this:
function sendemail() {
const ss = SpreadsheetApp.getActive();
const sh = ss.getActiveSheet();
const sr = 2;
const rg = sh.getRange(sr, 1, sh.getLastRow() - sr + 1, 4);
const vs = rg.getValues();
vs.forEach((r, i) => {
let Subject = "New Content on IG.com";
let message =
"<p><b>Title: </b>" + r[0] + "</p>" +
"<p><b>Article: </b>" + r[1] + "</p>" +
"<p><b>Published Date: </b>" + r[2] + "</p>";
let EmailSent = r[3];
let SendTo = "TEST#gmail.com";
if (EmailSent != "Yes") {
sh.getRange(i + sr, 4).setValue("Yes");
MailApp.sendEmail({to: SendTo,cc: "",subject: Subject,htmlBody: message});
}
})
}
