How to reduce Squarespace automated emails?

Site URL: https://litclub4kids.com.au/

Hello! 

When you sign up to become a member of our member area, you automatically receive 3 emails: 

1. Confirmation of the subscription 

2. Welcome email (email notification) 

3. Verify your account

Is there a way to reduce this so you don't receive all 3? Given the nature of our website there is no need to verify the account and confirm subscription. This should just be one process. Perhaps if there's a way to integrate reCAPTCHA so you tick a I'm not a robot box this can replace the confirmation and verification email? Our website is for children so these extra steps are quite an obstacle. I'm not sure how I would go about integrating recapture to avoid double opt in. 

Thank you in advance for your help!

Best regards, 

Meg

Unfortunately, you cannot prevent double opt-in for member areas with reCAPTCHA.
