I would like to know if Zoho CRM has a verified opt-in or double opt-in as we call it here. 

This would be the mail a user receives upon entering his data in a contact-form of yours to receive a newsletter, in which he needs to confirm his request before I can send him the newsletter.

I do not mean the fact of redirecting the user to a thank you page. 

Does Zoho have this?

Thank you!

kind regards,

Lars
