Overview

Double opt-in is an email subscription process where a user signs up and then must confirm their email address by clicking a verification link sent to their inbox.

This ensures the address is valid, prevents fake or mistyped signups, and improves email deliverability and compliance.

There are two ways double opt-in can be enforced in Encharge.

1. Encharge Forms
2. Flows

Double Opt-in using Encharge Forms

You can get to the forms page when you press "Forms" on the menu at the top or through here.

You can build your own form by following the steps inside this article.

Once the form has been created, inside the fields tab, you have to navigate down to "Double Opt-in" section and press to enable it.

Once the Double Opt-in is enabled, you need to choose or build your confirmation email.

You can add the confirmation link as a hyperlink or on a button.

Double Opt-in using Flows

1. Create your confirmation email

Create a new email like this one and include the confirmation 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.

2. Create the confirmation Flow

Create the following Flow:

This Flow will automatically send the Confirmation email to all people that enter your Encharge account.

3. Create a segment of opted-in people

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.
