Google Sheets, how to send email with attachment to every customer - google-apps-script

Question

I have a sheet, with some tabs, in one tab i make statement for my clients, there i select a customer in B2 and using a query formula i get the desired data, after that i have a script to first hide blank rows and then send that email with the pdf as attachment, and i do thins only when need send that email.
this is my script:
function HideEdoCta() {
var ss = SpreadsheetApp.getActiveSpreadsheet()
var sheet = ss.getSheetByName('Edo Cta');
var lastRow = sheet.getLastRow();
var range = sheet.getRange(1, 4, lastRow, 1);
var data = range.getValues();
//Rows
for (var i = 0; i < data.length; i++) {
if (data[i][0] == 1) {
sheet.hideRows(i + 1)
}
}
sheet.hideColumns(4, 1)
}
function UnHideEdoCta() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Edo Cta');
sheet.unhideRow(sheet.getDataRange());
}
function MailEdoCta(email, subject, body, sheetName) {
var ss = SpreadsheetApp.getActiveSpreadsheet()
var sheet = ss.getSheetByName('Edo Cta');
var valueToCheck = sheet.getRange('C1').getValue();
if (valueToCheck == true && casa != '') {
HideEdoCta()
SpreadsheetApp.flush()
var email = sheet.getRange('D1').getValue(); // Enter the required email address here
var casa = sheet.getRange('B2').getValue();
var subject = 'Estado de Cuenta Sky';
var body =
"Hola, <strong>" + casa + "</strong><br><br>" +
"xxx.<br>" +
"-- <br>" +
"<strong>xxx</strong><br>"
;
// Base URL
var url = "https://docs.google.com/spreadsheets/d/SS_ID/export?".replace("SS_ID", ss.getId());
var url_ext = 'exportFormat=pdf&format=pdf' // export as pdf / csv / xls / xlsx
+ '&size=letter' // paper size legal / letter / A4
+ '&portrait=true' // orientation, false for landscape
+ '&scale=1' // 1= Normal 100% / 2= Fit to width / 3= Fit to height / 4= Fit to Page
+ '&fitw=true&source=labnol' // fit to page width, false for actual size
+ '&sheetnames=false&printtitle=false' // hide optional headers and footers
+ '&pagenumbers=true&gridlines=false' // hide page numbers and gridlines
+ '&fzr=false' // do not repeat row headers (frozen rows) on each page
+ '&gid='; // the sheet's Id
var token = ScriptApp.getOAuthToken();
var response = UrlFetchApp.fetch(url + url_ext + sheet.getSheetId(), {
headers: {
'Authorization': 'Bearer ' + token
}
}).getBlob().setName(sheet.getName() + ".pdf");
// Uncomment the line below to save the PDF to the root of your drive.
// var newFile = DriveApp.createFile(response).setName(sheet.getName() + ".pdf")
GmailApp.sendEmail(email, subject, "",
{ name: 'xxx', htmlBody: body, attachments: [response] }
);
SpreadsheetApp.flush()
UnHideEdoCta()
sheet.getRange('C1').setValue(false)
sheet.getRange('B2').clearContent()
}
else {
sheet.getRange('C1').setValue(false)
}
}
in this script i have a validation that if there is a customer selected in B2 and C1 is true, send the email, because the trigger is set to run every minute.
now what i need is send the same email, every 5th of the month to all my customers automatically (i only have 24 customers)
how can i make this possible without selecting one by one ?
any help please ?
here is a sample sheet with sample data

Answer 1

Try this
function mailing() {
var doc = SpreadsheetApp.getActive();
var sh = SpreadsheetApp.getActiveSheet();
var data = doc.getRange('listOfCustomers').getValues();
for (var i = 0; i < data.length; i++) {
if (data[i][1]) {
sh.getRange('B2').setValue(data[i][0]);
SpreadsheetApp.flush();
Utilities.sleep(1000);
}
}
};
a copy of your spreadsheet would have been appreciated for testing.

In response to your comment from above:
This is the basic script that reads the information spreadsheet and calls the email function along with an object that identifies the template and other important information.
function sendEmails() {
const ss = SpreadsheetApp.getActive();
const sh = ss.getSheetByName('Emails');
const [hA, ...dt] = sh.getDataRange().getValues();
const vs = dt.filter(r => r[0] && r[1] && r[2] && r[3] && r[4] == 'Send' && r[5]);
const idx = {};
hA.forEach((h, i) => { idx[h] = i; });
vs.forEach(function (r) {
let obj = { index: idx, row: r }
this[r[5]](obj);//This executes the function named in r[5] and passes it obj
});
}
This is one of the functions that sends emails or creates a draft:
function sendEmails103(obj) {
const ss = SpreadsheetApp.getActive();
const sh = ss.getSheetByName('libImages');
const [hA, ...dt] = sh.getDataRange().getValues();
let idx = {};
hA.forEach((h, i) => idx[h] = i);
let imgObj = {};
vs = dt.filter(r => r[idx['filename']] == obj.row[obj.index['htmlFile']])
vs.forEach((r, i) => {
let params = { muteHttpExceptions: true, headers: { "Authorization": "Bearer " + ScriptApp.getOAuthToken() } };
let aurl = "https://photoslibrary.googleapis.com/v1/mediaItems/" + r[idx['mediaItemId']]
let resp = JSON.parse(UrlFetchApp.fetch(aurl, params).getContentText());
let burl = `${resp.baseUrl}=w${r[idx['maxwidth']]}-h${r[idx['maxheight']]}`
imgObj[r[idx['Key']]] = UrlFetchApp.fetch(burl).getBlob();
});
let htmlTemplate = HtmlService.createTemplateFromFile(obj.row[obj.index['htmlFile']]);
let html = htmlTemplate.evaluate().getContent();
if (html) {
if (obj.row[obj.index['operation']] == 'Create Draft') {
GmailApp.createDraft(obj.row[obj.index['Recipients']], obj.row[obj.index['Subject']], '', { htmlBody: html, inlineImages: imgObj, replyTo: obj.row[obj.index['replyTo']] });
} else {
GmailApp.sendEmail(obj.row[obj.index['Recipients']],obj.row[obj.index['Subject']],'',{htmlBody:html,inlineImages:imgObj,replyTo: obj.row[obj.index['replyTo']]});
}
}
}
This probably not for everyone, but I like having more room to customize my letters and having been a web developer for a long time I'm quite comfortable composing letters in html which is probably not true of everyone.
