我正在寻找一种方法来过滤客户信息到变量，我可以用来发送电子邮件。我寻找的变量之一是“nospam1@gmail.com“谁能帮我这个？
我测试的代码是：

import json

with open('notion_data.json') as json_file:
    data = json.load(json_file)

if [x for x in data['properties'] if x.get('plain_text')=='nospam1@gmail.com']:
  print("IN")
else:
  print("NOT")

The error i get: 
Traceback (most recent call last):
  File "C:\Users\stijn\PycharmProjects\notion\scrath_notion.py", line 13, in <module>
    if [x for x in data['properties'] if x.get('plain_text')=='nospam1@gmail.com']:
                   ~~~~^^^^^^^^^^^^^^
KeyError: 'properties'

Process finished with exit code 1

json文件的数据：

  "results": [
