I was looking for a way to disable newsletter module in Magento. The newsletter module is in place by Magento default install and is really complicated to remove by playing around with module positions in design.
Here's how to completely disable Magento's newsletter module:
- Log in to Magento's backend
- Go to System -> Configuration -> Advanced
- Find Mage_Newsletter and from the dropdown select Disabled
- Save configuration
- Flush Magento cache (System -> Cache Management -> Flush Magento Cache)
- Refresh your Magento page and see that the newsletter module is disabled/gone/disappeared.
