MailPoet WooCommerce Add-On is a simple plugin that adds a checkbox on checkout page for your customers to subscribe to your MailPoet newsletters.
Simply config this plugin under WooCommerce -> Settings in the MailPoet tab. The settings are in two sections. ‘General | Newsletters’.
Under ‘General’ simply enable the checkbox field to show on the checkout page.
You can also change the label of the checkbox. Default ‘Yes, add me to your mailing list’.
Next is ‘Newsletters’. Each list you created in MailPoet that you have enabled to send to is listed here. Simply tick the checkbox next to the Newsletter list your customers will be subscribed to and press ‘Save Changes’.
That’s it, now when your customers tick the subscribe button on the checkout page, they will be subscribed to the newsletters you selected when processing an order.
