Hi,

In your Automated Action, set the action type to "Execute Python Code" and use this:

# Get the assigned user

user = record.user_id  # adjust field name if different in your version

if user and user.email:

mail = env['mail.mail'].sudo().create({

        'subject': 'Inventory Count Assigned to You',

        'body_html': f"""

            <p>Hello {user.name},</p>

            <p>An inventory count has been assigned to you.</p>

            <p><b>Reference:</b> {record.name}</p>

            <p>Please log in to Odoo to review and complete it.</p>

        """,

        'email_to': user.email,

        'auto_delete': True,

    })

mail.send()

This bypasses the mail.thread restriction entirely by creating and sending an email directly through the mail queue.

Hope it helps
