How do I disable notification emails in Magento?

Question

How do I disable a particular notification email, for example the welcome email when a user creates an account?

Answer 1

There is no buit-in ability to disable particular email notifications in Magento. I suggest you to look at the Mage_Core_Model_Email_Template::sendTransactional method. You can overload this class and add check against allowed/disallowed email notifications (based on template name).

Update: you can use extension for disabling specific email notifications in Magento 1.

Also, there is Disable Emails extension for Magento 2.
