How to change optin from double to single and then redirect to a new website?
Hey Frances, welcome in! You can change the settings for confirmed opt in on the Confirmation Message page under List Settings. Keep in mind having double opt in enabled can help with the health of your list.
If you would like subscribers to go to a specific page after they fill out your sign up form (or landing page), you would set the Thank You Page url as the page you’d like them to go to. This would be the process with double opt in on or off.
