magento2 – Is it safe to delete directly from the newsletter_subscriber table?

I've recently activated e-mail confirmation for visitors who sign up for the newsletter. I would now like to delete all subscriptions to the newsletter made before.

While the database table newsletter_abonné has a date column change_status_at, this column is not displayed in the administrator, so I can not filter and delete only the old subscriptions.

Ideally, I would just like to run a simple query on the database, which will delete everything I want. However, I am very careful about running queries directly on the Magento database because I am afraid of unexpected interactions.

I've searched in the database schema forign key references to the columns of the newsletter_abonné table, and can not find.

Is there a way to make sure it's a standalone table and that it's safe to delete?
