Hi @wojewodzic, thanks for reaching out!
If you are using CartBounty Pro, you can go over to settings and enable automated anonymous shopping cart removal.
If your client uses the free version, then there are three options:
a) Manual deletion of anonymous abandoned carts. Opening Abandoned cart tab and under screen options changing to display 500 carts. Then use Bulk delete to remove shopping carts,. But removing 95K would rather time consuming.
b) Going directly into database and running an SQL
DELETE FROM wp_cartbounty_pro WHERE email = '' && phone = '' && type = '0'
c) Deleting CartBounty plugin and reinstalling it. This option means that all settings and abandoned carts will be deleted (including recoverable, recovered etc.)
Please let me know if you need additional details.
