Back In Stock Notifications for WooCommerce

I have a very important question, will there be a re-subscription in case of a mail change? For example, I registered with the mail a1@mail.com and subscribed to product X. After some time, I changed the mail in my personal account to a2@mail.com . What will happen to my subscription to product X? I will receive an email about the availability in the mail a1@mail.com or a2@mail.com ? I should not receive an email in the mail a1@mail.com since I changed this mail in my personal account and now my mail a2@mail.com , will the plugin work correctly? Or he will try to send an email about the availability to the old mail a1@mail.com
