How to prevent double optin when a user registers to buy a Studio?

Hi, after a new user enters their email address and password to register (so they can purchase a Studio), the systems sends them an email verification request:

I have an automation in Zapier that every time there is a Studio purchase, the user is added to an email marketing list, so he will receive my own double optin and instructions to use the Pickaxe, so I don’t need Pickaxe to send them also another double option email —that can be confusing for the user.

How can I prevent Pickaxe from sending that double optin email? Thank you!

You cannot prevent the Studio from sending a verification email. It’s how we verify their email is a real email. If you use Google Oauth though, it will not send them a verification email.
