Limiting form entries per day in FreeForm
I managed to get this working in the end. Here is my final code;

{# Calculate entries per day #}
{% set form = entry.form %}
{% set todaysEntriesIndex = 0 %}
{% set submissions = craft.freeform.submissions({
    form: form.handle
}).all() %}

{# Count each submission from the day #}
{% for submission in submissions %}
    {% if submission.dateCreated | date('d/m/Y') == 'now' | date('d/m/Y') %}
        {% set todaysEntriesIndex = todaysEntriesIndex + 1 %}
    {% endif %}
{% endfor %}


Once this has been setup you can use the following to check the amount:

 todaysEntriesIndex &gt;= 200
