How can I create a segment where it tells me which users have not confirmed the double opt-in?

Hi @Sanket 

@KatherineB is spot on. If a contact does not actively verify their email when subscribing to a list that requires a double opt-in, then the will be added as a new profile in Klaviyo, but not added to the designated list from the sign-up form. There name, email, and some of those initial data points will be saved, but my guess is their email status will be “Never Subscribed,” and they won’t be added to the list. 

In terms of your current set up, make sure you have messaging on the thank you page of the sign up process to direct people to look for the email to verify their subscription. Often times, people don’t realize they need to verify their email and that message ends up getting buried in their inbox.

While the contact may not have subscribed to a specific list, once they are cookied, they can be sent the activity messages such as Cart Abandon, Browse Abandon, etc. However, depending on location, you’ll want to verify the rules for implicit vs. explicit consent for mailing.

If that is the case, you might be able to create a Hide/Show block specific to people who have not subscribed to your primary list of these messages to encourage users sign up for promotions. In as many places as possible, you’d want to direct people to check their inbox to verify there email address. 

Best,

@Sanket If you create a segment of people who have never subscribed to a list and are not suppressed for email, this will include people who did not confirm double opt in.

The caveat, however, is that this segment may also include bots. Let me know if that works for you!
