Claude sends an SMS verification email immediately after a new user signs up. Operating on a freemium model, they know that their platform is subject to abuse so they hope that this extra verification step will help curb some of that before their own usage bills balloon.

Even though this is a transactional email and therefore does not require an unsubscribe link, Layers offers a direct link for recipient's to manage all of their notification preferences. This extra addition helps build trust from the very first interation with new users.
