I placed this code in my functions.php file of my theme but it didn't seem to delete anything. Saw a lot of errors appearing saying the following

Undefined index: user_id in....
Undefined index: subscription_id in...

I am using version 2.1.1 of WooCommerce Subscriptions.

This is an updated version that might work better for you: https://gist.github.com/JPry/ed3f472d537408bc276a128d200842a8

For anyone who might come across this and not know - in the UI subscription list page, under 'screen options' you can increase the number per page to any size you like. If your server is fast enough you can then delete hundreds at a time via the UI.

@NickGreen - Thanks. That worked for me.

Does it sends an email to the user?

@davidperezgar I wrote this a long time ago so I can't recall if it does. The code base for WC and Subscriptions has probably change a lot based on some of the other comments from others.

Simply deleting a post using wp_delete_post doesn't send anything. And even if you uncomment the subscription status change as shown in my version of the script, by default, there is no customer email that is sent when a subscription gets cancelled. You would have to add a line there that sends a custom email to the customer.
