Double Opt-in Subscribers to a Segment
To enforce a double opt-in process for your contacts, you can create a Flow.
To do that follow the instructions below.
Create a new email like this one and include the confirmation email link in it:

For the confirmation link, you need a custom landing page like yourwebsite.com/subscription-confirmed thanking subscribers for confirming the opt-in.
Alternatively, you can use a UTM/ref link that leads to your homepage for instance yourwebsite.com/?ref=subscription-confirmed
It's critical that you include a unique confirmation link and not a link to your homepage.
Create the following Flow:

This Flow will automatically send the Confirmation email to all people that enter your Encharge account.
The last step is to create a segment of people that have clicked on the confirmation link.
Use the "Email Activity" condition and segment all people that have clicked on the confirmation link:

This will create a segment of people that have opted in to receive emails from you.
Finally, ensure that you're only sending Flows and Broadcasts to this segment of people.
To do that follow the instructions below.
