GmailApp not sending emails to gmail account every time

Question

I am using this code to send emails (composing email content getting text from the sheet named ranges:

 //compose issue emails to student and admin function composeIssueEmail() { //student's name, last name and email var email = ss.getRangeByName("CourseProgressEmail").getValue() var name = ss.getRangeByName("CourseProgressName").getValue() var lastName = ss.getRangeByName("CourseProgressStudentLastName").getValue() var subj = ss.getRangeByName("SetUpIssueTitle").getValue() var subject = subj.replace("*imya*", name) var bodyText = ss.getRangeByName("SetUpIssueBody").getValue() var body = bodyText.replace("*imya*", name) var link = getChecksheetURL() var text = body.replace("*link*", link) //send email to student var studentEmail = sendEmail(email, subject, text) var adminEmail = "AGcourseSup@gmail.com" var adminSubj = ss.getRangeByName("SetUpAdminIssueTitle").getValue() var adminSubject = adminSubj.replace("*imya*", name) var adminSubjectFinal = adminSubject.replace("*familia*", lastName) var adminText = ss.getRangeByName("SetUpAdminIssueBody").getValue() var adminTextReplace = adminText.replace("*imia*", name) var adminBody = adminTextReplace.replace("*familia*", lastName) var adminText = adminBody.replace("*link*", link) //send email to admin sendEmail(adminEmail, adminSubjectFinal, adminText) } //gets current checksheet URL function getChecksheetURL() { var Url = ss.getUrl() var linkMiddle = "#gid=" var sheetID = sheet.getSheetId() var shecksheetURL = Url + linkMiddle + sheetID return shecksheetURL } //sends emails function sendEmail(email, subject, body) { GmailApp.sendEmail(email, subject, body) } 

Execution transcript: [19-06-12 16:39:43:396 EEST] Execution succeeded [2.399 seconds total runtime]

It sends stably to the gmail account that is the same as spreadsheet's one.

But to another gmail account it sends about every other time.

Details:

• This code is executed (I log the line after this code)

• The emails are visible in my outbound box but not arriving to any of the boxes of the recepient gmail.

• Not in spam etc.

• I don't get any messages, error or bounce notifications.

I tried MailApp instead - it's even worse and sometimes doesn't send even to my own email.

I tried to change things in settings config, but didn't find anything to work.

I set up a filter "never send to spam" and "always star it" - didn't work.

I deleted a link from it so it has no link - didn't work.

What can be a solution?

Answer 1

I handled this issue. The issue is about anti-spam filters not about the code.

I gained more trust to the email account by adding "Reply To" option within GmailApp.sendEmail method. It magically solved the problem so each email reaches target now.
