Opt Out Helper Functions

To give a customer the option to unsubscribe from receiving marketing messages, you can generate a dynamic link using the opt-out helper function.

The syntax of this helper function is:

{{{optOutLink 'channel'}}}

Please note the usage of triple braces {{{...}}}for the opt-out helper syntax. This is done to ensure that no variables required by a link tag is accidentally escaped.

CrossEngage offers 3 types of opt-out:

1. Opt-out from the current channel a message was dispatched through

2. Opt-out from a particular channel

3. Opt-out from all channels

The links generated by the opt-out helper will only unsubscribe users from CrossEngage messages. This will not update the opt-out status of a user in a particular integration.

Opt-out from messages sent from the current channel:

To opt-out a user from the current channel a message was dispatched through, use the following syntax within a message template or mapping field value:

{{{optOutLink}}}

Opt-out from messages sent from a specific channel:

To opt out users from channels other than the one the message is dispatched through, use the following syntax within a message template or mapping field value:

{{{optOutLink 'Channel'}}}

Depending on the channel you would like to produce the link for, you may choose one of the following values:

Value	Description
MAIL	Opt-out from all marketing emails.
DIRECT_MAIL	Opt-out from all direct mail campaigns.
BROWSER_NOTIFICATION	Opt-out from browser notifications.
ONSITE_DISPLAY	Opt-out from all onsite display promotions.
EXIT_INTENT	Opt-out from all exit intent messages.
PUSH_NOTIFICATION	Opt-out from all push notifications across all devices.
SEGMENT_TRANSFER	Opt-out from all segment transfer campaigns, e.g. Facebook Custom Audiences.
SMS	Opt-out from SMS messages.
WEBHOOK	Opt-out from all webhook campaigns.

Opt-out from messages sent from all channels:

To opt-out users from all channels, you simply need to replace the Channel value with ALL:

{{{optOutLink 'ALL'}}}

Use cases

Generating an opt-out link for an email message

For this example, we will prepare the opt-out link for an email message that will be dispatched as part of a future campaign. In the footer section of the email, we will include the opt out link through a hyperlink tag <a></a>:

<footer>
<p>Don't want to receive these emails?</p>
<p>You can unsubscribe <a href="{{{optOutLink}}}">here</a>.</p>
</footer>

Once the function is evaluated, it displays a link similar to the following example:

<footer>
<p>Don't want to receive these emails?</p>
<p>You can unsubscribe 
<a href="https://api.crossengage.io/optout/inbound/webhook/[YourWebtrackingAPIkey]/[XngId]?channelType=MAIL&messageId=[CEMessageId]">here</a>.</p>
</footer>
