Automated emails can be an effective way for businesses to improve their customer communication and streamline their operations. Odoo's Send Email action in the automation feature enables users to set up emails to be sent automatically based on specific triggers or events, such as a customer placing an order. These emails can be customized with personalized content, allowing businesses to provide a more personalized experience for their customers. By automating these emails, businesses can save time and resources that can be allocated to other areas of the business. In the screenshot below, you can see automatic action for sending mail to customers when a sale order is created.
