Summary / TL:DR: This article will show you how list unsubscribes function in the refactored instance of Blueshift.
Trigger Level Custom Parameters
In the refactored instances of Blueshift a custom query parameter will be added to all links by default. This query parameter that’s defined at the trigger level eliminates the need to add the necessary query parameters at the creative level in order for list unsubscribes to work. Below shows the key-value pair:
key = vid2
value = {{ user_transaction.advantage_customer_number | append: '@@' | append: user_transaction.list_code | append: '@@' | append: user.email | aes256_encrypt_v2: '50655368566D597133743677397A24432646294A404E635266546A576E5A7234', '472B4B6250655368566D597133743677' }}
Defining an Unsubscribe Link
Within your email templates, your <a> tags need to be modified to include the unsub_link variable using liquid script.
<a href="{{unsub_link}}">Unsubscribe</a>
Important Note: You must have your unsubscribe links defined inside of the link algorithm and your base/wiki/spaces/BSSUPPORT/pages/13633203987list transaction starred in the advanced segment builder.
Putting it all together
A typical HTML email might look like the following
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>My Nifty Email</title>
</head>
<shared_asset> bsft_Link_Algorithm </shared_asset>
<body>
Hi there, I am an unsubscribe link <a href="{{unsub_link}}">Unsubscribe</a>
</body>
</html>
Wrap up
You should now know how to utilize unsubscribe links inside an email template.
