Emails being sent through n8n but not received

Describe the problem/error/question

I am using a Gmail node to send emails to around 30 users, with time schedule (custom cron setting) set as the trigger. n8n logs the executions as complete, my sent box in Gmail logs all emails as sent but my users are not able to receive my mails.

Has this error occurred to anyone? Is it a problem on n8nโ€™s side or gmailโ€™s?

Also wondering if using a different node to send email (other than Gmail) might help, we are looking for the quickest fix.

What is the error message (if any)?

None.

Information on your n8n setup

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Hey @deeplinkwriting hope all is good. Welcome to the community.

Since a lot of the workflow is in Korean, could you please also include an example of the sheet content (headers and some rows)?

Hi jabbson, hope allโ€™s going well too.

The workflow basically just gets rows in the sheet, uses one filter to sort out email recipients, one other filter to sort out if the recipient is a new user or a recurring user, and sends the corresponding version of the email.

An example of a row in the sheet in json format as below;

@jabbson had the same error. The Gmail node give sent output but the email is not found in inbox, spam, promotions..

@deeplinkwriting Can you save the raw content of the sent email in a file and upload it here so I can check a few things?
