Hi,

If your automated action and cron job run successfully but no emails are generated, it usually means Odoo isn’t actually triggering the “Send Email” step. First, check your automated action in Settings → Technical → Automation and make sure the Action To Do field is set to Send Email. If it’s using Execute Python Code, ensure the code explicitly calls the email template with something like template.send_mail(record.id, force_send=True). Without this, no messages are created.

Next, review the email template under Settings → Technical → Email → Templates to confirm it’s active, linked to the correct model, and has a valid recipient address. You can test it manually with “Send Test Email.” If that works, check the Outgoing Emails list to verify that messages are being queued, and confirm that your Outgoing Mail Server configuration is valid and can send emails successfully.

Finally, verify that the user running the automation has permission to create and send emails, and that the domain in your rule actually returns records. If everything looks right but emails still don’t appear, try creating a simple test automation (for example, on contacts) to confirm that the mail system itself works. Once the rule is configured with a proper action, valid template, and an authorized execution user, Odoo will generate and send the scheduled emails as expected.
