In this article, you will learn how to set up double opt-in on your sales funnel.
What you will need:
A systeme.io account
A sales funnel (How to create a new funnel)
An opt-in page (How to create an opt-in page)
To activate double opt-in, open the page editor by clicking Edit page (1).

Click the Settings (gear) icon (2) on your button element.

Check the box labeled Do you want to enable double opt-in on this form? (3).

To customize the confirmation email sent to prospects, select Settings (1) under your profile picture, then click Emails (2) under Products and marketing.

Scroll down to the Double opt-in section, then click Edit confirmation email (3) to customize its content.

Edit the confirmation email as needed, then click Save (4) to apply your changes.

Notes:
Consider using double opt-in for your blog forms to improve email deliverability.
If a contact doesn't click the confirmation link within 24 hours of registering, they will automatically be deleted.
Double opt-in is configured individually for each form, not at the account level.
All emails and automations are paused until the contact has confirmed their registration by clicking on the confirmation link.
