python - 如何在 python 中向多个组发送 smtplib 电子邮件？

Question

import smtplib
from email.message import EmailMessage

list1=[
    'Person 1 <[e-mail]>',
    'Person 2 <[e-mail]>'
    ]
    
list2=[
    'Person 3 <[e-mail]>',
    'Person 4 <[e-mail]>'
    ]
    
masterlist = [list1, list2]

for x in masterlist:
    receivers = ", ".join(x)

msg = EmailMessage()
msg['Subject'] = 'This is a Test Email'
msg['From'] = 'Person 5 <[e-mail]>'
msg['To'] = receivers
msg.set_content('Ignore this message')

with smtplib.SMTP('smtp.outlook.com', 587) as smtp:
    smtp.send_message(msg)

这是我使用的代码。我想将此电子邮件发送给某些组，但不会将所有电子邮件合并到一封电子邮件中。我现在的方式只是将电子邮件发送到最后一个电子邮件列表。我应该如何修改它以便能够将其发送到多个电子邮件列表？

import smtplib
from email.message import EmailMessage

list1=[
    'Person 1 <[e-mail]>',
    'Person 2 <[e-mail]>'
    ]
    
list2=[
    'Person 3 <[e-mail]>',
    'Person 4 <[e-mail]>'
    ]
    
masterlist = [list1, list2]

for x in masterlist:
    msg = EmailMessage()
    msg['Subject'] = 'This is a Test Email'
    msg['From'] = 'Person 5 <[e-mail]>'
    msg['To'] = x
    msg.set_content('Ignore this message')

    with smtplib.SMTP('smtp.outlook.com', 587) as smtp:
        smtp.send_message(msg)

我可以通过根据电子邮件列表将电子邮件部分放入 for 循环来纠正此问题。
