import smtplib
import time
from email.mime.application import MIMEApplication
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImagedef send_email(send_to):# 钉钉邮件smtp_server = 'smtp.qiye.aliyun.com'  # 替换为你的SMTP服务器地址username = '123@net.cn'  # 替换为你的SMTP用户名,就是发件人邮箱password = '123'  # 替换为你的SMTP密码sender_email = username   # 替换为你的发件人邮箱# 创建邮件对象msg = MIMEMultipart()msg['From'] = username  # 发件人地址msg['To'] = send_to  # 收件人地址,可以是多个，用逗号分隔# msg['To'] = '123@qq.com,123@net.cn'  # 收件人地址,可以是多个，用逗号分隔msg['Cc'] = ''  # 抄送人地址,可以是多个，用逗号分隔msg['Subject'] = '活动预热丨账号免费领！立享 20 个月账号！'  # 主题# 添加文本内容，图片超链接text = """<html><body><a href="https://co.cn/#/Activity"><img src="cid:image1" alt="Example Image"></a></body></html>"""# 添加邮件正文msg.attach(MIMEText(text, 'html'))# 添加图片with open('PC.png', 'rb') as file:img = MIMEImage(file.read())img.add_header('Content-ID', '<image1>')msg.attach(img)# 添加邮件正文# msg.attach(MIMEText("这是一封测试邮件", 'plain'))# 添加附件# file_path = r'E:\data'  # 附件地址# attachment_name = 'jd_07161753.txt'  # 替换为附件名称# for file_name in attachment_name.split(";"):#     with open(file_path + "\\" + file_name, 'rb') as file:#         attachment = MIMEApplication(file.read())#         attachment.add_header('Content-Disposition', 'attachment', filename=file_name)#         msg.attach(attachment)# 发送邮件try:server = smtplib.SMTP(smtp_server)server.starttls()server.login(username, password)server.sendmail(sender_email, msg['To'].split(",") + msg['Cc'].split(","), msg.as_string())server.quit()print(msg['To'] + " 邮件发送成功")except Exception as e:print('邮件发送失败：', str(e))if __name__ == '__main__':with open('telphone.csv', 'r', encoding='utf-8') as f:lines = f.readlines()for line in lines:# send_to = '123@net.cn,25@qq.com,1234@net.cn'  # 收件人地址,可以是多个，用逗号分隔send_email(line)time.sleep(5)
