Redirect to page XYZ after newsletter form submitted

Hi,

I want my client to be redirected to specific page - after they submits contact form.

QUESTION: What should I add to the code - if I want them to be redirected to “www.xyz.com/thank-you

{% form ‘customer’ %}
{% if form.posted_successfully? %}
{% elsif form.errors %}
{% for field in form.errors %}

{{ field }} - {{ form.errors.messages[field] }}

{% endfor %} {% endif %}

{%- if form.posted_successfully? -%}

{%-elsif -%}
