Add Email Signature to Email Notification Script - email

Question

I am writing a code on Google Apps Script to send an email every time there is a new announcement made in my site. Here is the code for reference:
var url_of_announcements_page = "https://sites.google.com/announcements";
var who_to_email = "emailaccount";
function emailAnnouncements(){
var page = SitesApp.getPageByUrl(url_of_announcements_page);
if(page.getPageType() == SitesApp.PageType.ANNOUNCEMENTS_PAGE){
var announcements = page.getAnnouncements({ start: 0,
max: 10,
includeDrafts: false,
includeDeleted: false});
announcements.reverse();
for(var i in announcements) {
var ann = announcements[i];
var updated = ann.getLastUpdated().getTime();
if (updated > PropertiesService.getScriptProperties().getProperty("last-update")){
var options = {};
options.htmlBody = Utilities.formatString("<h1><a href='%s'>%s</a></h1>%s", ann.getUrl(), ann.getTitle(), ann.getHtmlContent());
MailApp.sendEmail(who_to_email, "Announcement - '"+ann.getTitle()+"'", ann.getTextContent()+"\n\n"+ann.getUrl(), options);
PropertiesService.getScriptProperties().setProperty('last-update',updated);
}
}
}
}
function setup(){
PropertiesService.getScriptProperties().setProperty('last-update',new Date().getTime());
}
I would like to know if it is possible to add my gmail signature to the code. As when I send it with the script my signature is removed. Do I have to make my signature in the code or am i able to get my signature from gmail and automatically insert it at the end? Here is the line for the formatting of the email:
MailApp.sendEmail(who_to_email, "Announcement - '"+ann.getTitle()+"'", ann.getTextContent()+"\n\n"+ann.getUrl(), options);

Answer 1

Apps Script cannot access user's signature: there is no method for that in MailApp, or GmailApp, or even in Gmail API accessible via Advanced Google Services.
In principle, you could use GmailApp to get a recent outgoing message and search its text for the signature contained after the last -- found in message body. But this requires giving the script a lot more access (GmailApp can access, forward and delete existing email, unlike MailApp) and is error-prone (when text parsing fails, you might end up with an embarrassing fragment of text in your message).
Just append it directly:
var signature = "\n\n--\nFirstName LastName";
// ...
MailApp.sendEmail(... +signature, options);
(By the way, Gmail web interface and Gmail mobile app have different user signatures in general, so having another one for script-generated messages doesn't seem unusual.)
