<h4>Introduction</h4>
Thank you for trying In Stock Mailer for WooCommerce!
This WooCommerce extension allows your online store to have a customizable in stock alert button and email. If a product or product variation is out of stock this plugin will display an animated button with a “Notify when available” option. 
Registered users can simply click on the button and they will be automatically notified by email when the product/s is back in stock. In addition, your Mailchimp account can be linked to this plugin and new visitors email can be added for future marketing campaigns. 
This is a useful tool to collect email and consent from a visitor.
For optimal customer experience, non-registered users/visitors will be prompted to enter their email address only once since it will be saved in a cookie; Once a product or more products become available, the application will check and group the requests by email address, and send one email per customer, including images and links to the product pages they were initially interested in.
In the admin pages you can see the pending alert requests and email sent to customers, sort by date, users and status or group requests by email address. You can also customize your back in stock email, which will always begin with “Hello {customer name},”; You can choose a custom header image that shows in the top of the email, a custom subject and even modify the body of the email.
<h4>Notes</h4>
It’s important to understand that this plugin uses cookies. It’s your responsibility to abide any laws and regulations within your country or jurisdiction ( eg. EU Cookie laws ).
