how to remove a newletter popup when someone subscribes in django

Using Django Forms & APIs

when someone subscribes to the newsletter i automatically want to remove the popup for the user that just subscribed, i tried create a subscribed = False then change it to subscribed = True when a user subscribes. but it doesnt work. i can easily achieve this is a user is logged i, but in this case even unauthenticated users can also subscribe to the newsletter so that is where the issue comes in.

views.py

subscribed = False
    if request.method == "POST":
        form = NewsLetterForm(request.POST)
        if form.is_valid:
            form.save()
            messages.success(request, f"Subscription Successfull, Thank you!! - Now check your mail")
            subscribed = True
            return redirect('/')
    else:
        form = NewsLetterForm()

models.py

{% if subscribed != True %}
<p class="mb-0">Subscribe to our <b>NewsLetter</b></p>
<form class="form-inline" method="POST">
   {% csrf_token %}
   {{form.email}}
   <button type="submit" class="btn btn-success-soft btn-sm" type="submit">Get Now</button>
{% endif %}

Could you use the messages framework?

Django Docs has this Sessions-based example How to use sessions | Django documentation | Django

But without persistent user model, I am not aware of any possibility to never show this popup again

To add to @nemecek_f’s answer, using a querystring parameter may also be a solution. Though will depend on what the use case is.
