我正在尝试让SendGrid的基本“Hello World”工作，但目前还没有成功。响应返回代码202，表明它将发送电子邮件，但电子邮件从未发送出去。有人知道发生了什么吗？
import sendgrid
sg = sendgrid.SendGridAPIClient(apikey='**my-api-key**')
data = {
"personalizations": [
{
"to": [
{
"email": "me@gmail.com"
}
],
"subject": "Hello World from the SendGrid Python Library!"
}
],
"from": {
"email": "me@gmail.com"
},
"content": [
{
"type": "text/plain",
"value": "Hello, Email!"
}
]
}
response = sg.client.mail.send.post(request_body=data)
print(response.status_code)
