使用smtplib发送带有多个收件人的电子邮件可以通过以下步骤实现:
1. 导入所需的模块:
import smtplib from email.mime.text import MIMEText from email.mime.multipart import MIMEMultipart
2. 设置发送方和收件人信息:
sender = 'your_email@gmail.com' receivers = ['receiver1@gmail.com', 'receiver2@gmail.com', 'receiver3@gmail.com']
3. 创建一个包含邮件主体的MIMEMultipart实例:
message = MIMEMultipart() message['From'] = sender message['To'] = ', '.join(receivers) # 将收件人列表转为逗号分隔的字符串 message['Subject'] = 'Subject of the Email'
4. 添加邮件内容:
body = """ This is the body of the email. You can write your message here. """ message.attach(MIMEText(body, 'plain'))
5. 构建smtp服务器,并登录发送方邮箱:
smtp_server = smtplib.SMTP('smtp.gmail.com', 587)
smtp_server.starttls()
smtp_server.login(sender, 'your_password')
注意:在使用Gmail发送邮件时,需要开启SMTP和IMAP协议,并使用应用专用密码。
6. 发送邮件:
smtp_server.send_message(message)
7. 关闭smtp服务器:
smtp_server.quit()
完整的示例代码如下:
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
sender = 'your_email@gmail.com'
receivers = ['receiver1@gmail.com', 'receiver2@gmail.com', 'receiver3@gmail.com']
message = MIMEMultipart()
message['From'] = sender
message['To'] = ', '.join(receivers)
message['Subject'] = 'Subject of the Email'
body = """
This is the body of the email.
You can write your message here.
"""
message.attach(MIMEText(body, 'plain'))
smtp_server = smtplib.SMTP('smtp.gmail.com', 587)
smtp_server.starttls()
smtp_server.login(sender, 'your_password')
smtp_server.send_message(message)
smtp_server.quit()
使用以上代码,你可以发送带有多个收件人的电子邮件。只需将你的邮箱和密码替换为合适的值,并修改收件人的邮箱地址即可。
