Newsletter Disclaimers

[av4tarnz]

I'm working on layout changes for a clients Zen Cart site including email newsletters which display new disclaimers.
I've created my own variables, such as 'EMAIL_NEWSLETTER_DISCLAIMER', and have defined them in admin/includes/languages/english/email_extras.php and called them in email/email_template_newsletters.html.
I've also put the following line in includes/functions/functions_email.php:

if ($block['EMAIL_NEWSLETTER_DISCLAIMER']=='') $block['EMAIL_NEWSLETTER_DISCLAIMER'] = EMAIL_NEWSLETTER_DISCLAIMER;

But when it comes to testing, all I see is EMAIL_NEWSLETTER_DISCLAIMER and not its value in the received email.

What else do I need to do?
