What I meant is:

  product = data.get('product', 'adblockbrowser')

That way we don't need to explicitly handle None. Yes, we need to adapt the
server configuration then. But that is fine.

Done.

-  if product is not None:
-    email_template = product + '_verification_email_template'
-    params.append(('product', product))
+  product = data.get('product', DEFAULT_PRODUCT)
+  email_template = product + '_verification_email_template'
+  params.append(('product', product))
 
   sendMail(
     config.get('submit_email', email_template),
     {
       'recipient': email,
       'verification_url': '%s?%s' % (
         urljoin(wsgiref.util.application_uri(environ), VERIFICATION_PATH),

Same here.
