Simple & effective

I have spent the day looking for a simple plugin that would have minimal UI and would actually work with very little manual interaction.
The plugin only had one review which led me to think perhaps this wasn’t the one but I was wrong. This plugin will add a simple email and button to your single product page which you can easily style to your liking with a bit of CSS. It will also record a list of email addresses and it automatically emails the users upon updating the stock levels.
The only thing it doesn’t do is a confirmation email upon registering for the out of stock notice, but that’s okay.

Overall, if you want something simple and effective, this plugin is for you.
