Magento 2 provides this facility to send emails to customers. Along with that, it also sends a welcome email if the admin adds a new customer from the admin panel!
But there may be a situation where you would not want to send a email to the customers!
You can disable Email communication from the Admin Panel,
Login with admin panel,
- Go to Stores -> Settings -> Configuration,
- Choose Section, Mail sending Settings,
- Set Yes to Disable Email Communications Dropdown.
- Click on Top Right Save Config Button to save changes.
Also you can stop email sending for the specific store view level. Just choose specific store view scope from the Left Top bar and apply your changes for the store view level.
Thanks!
