Try this...

def send_email(request,id):
    customer=get_object_or_404(Customer,pk=id)
    form=Customer_Email_Form()
    customers=Customer.objects.all()
    context={"customer":customer,"email_form":form,"customers":customers}
    if request.method == 'GET':
        return render(request,'crm/listing.htm.html',context)
    if request.method=='POST':
        form=Customer_Email_Form(request.POST)
        if form.is_valid():
            form.save()
            messages.success(request,"Email Sent")
            return render(request,'crm/listing.html',context)
    return render(request,'crm/listing.html',context)

You were passing POST data to your form before any was sent, and then rendering the form. I find it easier/clearer to restructure as such:

def send_email(request,id):
    if request.method=='POST':
        form=Customer_Email_Form(request.POST)
        if form.is_valid():
            form.save()
            messages.success(request,"Email Sent")
            return redirect('send_email', id)
        else: 
            messages.error(request, form.errors)
            return redirect('send_email', id)
    
    else:
        customer=get_object_or_404(Customer,pk=id)
        form=Customer_Email_Form()
        customers=Customer.objects.all()
        context={"customer":customer,"email_form":form,"customers":customers}
        return render(request,'crm/listing.html',context)

Assuming that you have imported redirect and your url name in urls.py is 'send_email'.
