Enable double opt-in for webinar registrations

Applies to: WebinarJam and EverWebinar

A double opt-in subscription process requires people to confirm their email address after signing up, usually by clicking a link in a confirmation email. While it adds one extra step, it comes with several important advantages for list quality, deliverability, and compliance.

Why use double opt-in?

Double opt-in can help you:

• Improve email deliverability by confirming valid email addresses
• Reduce fake or mistyped registrations
• Maintain a cleaner registration list
• Ensure attendees actively agree to receive webinar communications
• Improve engagement rates from confirmed registrants

Enable double opt-in

To enable double opt-in registration for your webinar:

1. Edit your webinar. 
2. Go to the Registration tab. 
3. Locate Single or double opt-in. 
4. Select Double opt-in.
   

Once enabled, all new registrants must confirm their subscription before they are added to the webinar registration list.

Customize the double opt-in confirmation email

You can customize the double opt-in confirmation email from the Notifications tab. 

Important:

• The email must include the {CONFIRM_LINK} shortcode.
  
• The shortcode automatically inserts the confirmation link that registrants use to verify their subscription. 
• This email cannot be deleted. Without it,  users will not be able to confirm their subscription and the double opt-in flow will not work. Switch to the single opt-in option to disable this notification. 

What attendees experience

After a person registers for the webinar:

1. They are shown a message on the Thank You page asking them to check their email and confirm their subscription.
   
2. They receive the double opt-in confirmation email.
3. They click the confirmation link in the email.
4. After confirming, they are redirected to the standard Thank You page that displays their unique webinar room link.
