Welcome email

Hi all! Does anyone have an idea, why this code actually works and sends emails, but Fails on: send_email("admin@checkio.org","Alex") test on 'Check'? This assert actually could be passed, if I copy it directly into the 'asserts' block below my main code.

import sendgrid
from sendgrid import SendGridAPIClient
from sendgrid.helpers.mail import Mail, Content

API_KEY = "somekey"
SUBJECT = "Welcome"
BODY = "Hi {name}"

sg = sendgrid.SendGridAPIClient(API_KEY)

def send_email(email, name):
    global API_KEY
    global SUBJECT
    global BODY
    body=BODY.replace("{name}",name)

    message = Mail(
    from_email = "hustlingnotagame@gmail.com",
    to_emails = email,
    subject = SUBJECT,
    html_content = BODY)
    message.content = Content("text/plain", body)
    print(message)
    try:
        sg = sendgrid.SendGridAPIClient(API_KEY)
        response = sg.send(message)
        print(response.status_code)
        print(response.body)
        print(response.headers)
    except Exception as e:
        print(e.message)
