Each List has the Double opt in option set as manual. This means when someone subscribe to that list they will have to go in their email address and confirm the subscription and most of the time people are not doing this.

To turn this off you need to talk to chat and ask them to make double opt in option visible to you so you can turn it off. After this is available you can go in your list, click on settings of the list and than somewhere near the bottom you will see it checked. You should be able to change to single opt in.. this will make everyone that subscribe to your form automatically subscribe to your list to..

Hi @Jason1333,

Thanks for sharing this question with our Klaviyo Community. And thank you @Bobi N. for your informative post.

Bobi is completely correct. By default, when someone subscribes to a list, the user will have to confirm their subscription in their inbox before being added to that list. You may be well advised to add a call-out to the success message of your sign-up form for people to check their spam/junks/promotions folders for this confirmation message. Only once the user clicks the confirmation message in their inbox, will the user be added to the list and enter the flow triggered off of this list.

Additionally, if you’d like to circumvent this confirmation step altogether, you are no longer required to reach out to support to give you the ability to disable double opt-in. To achieve this, you can simply navigate to Lists & Segments > List > Settings scroll all the way to the bottom and modify the opt-in setting to Single opt-in.

Thanks and have a great day.
