Notification emails - adding a shipping address specific message

I want to include a shipping destination specific message on certain notification emails for orders with delivery outside of my country.

I am using the liquid string:
{% if shipping_address.country != ‘United Kingdom’ or ‘Isle of Man’ %}

message here

{% endif %}

I have this on the order confirmation, shipping confirmation, shipping update and out for delivery notification emails.

However, I see from email replies I receive from recipients that the message is being displayed to customers who ordered for delivery within the UK (which I don’t want it to be!)

What have I done wrong? Can the if shipping_address.country be used in notification email liquid?

Your if statement has an error, try this:

{% if shipping_address.country != 'United Kingdom' and shipping_address.country != 'Isle of Man' %}

 message here 

{% endif %}

Thanks Thomas, I shall try that now!
