说明
前两天使用阿里邮件推送批量发送邮件，但是一直报错，550，今天用脚本批量发送一下。
内容
首先，附上代码
config.json
{
"SMTP": {
"server": "smtp.qq.com",
"port": 465,
"username": "example@qq.com",
"password": "yourpassword"
},
"EmailContent": {

"Recipients": [
"example@qq.com",
"example@163.com",
"example@outlook.com"
]
}配置文件里面的HTML内容需要转义成json格式，保证格式正确，邮件内容如下图：
中奖通知
AutoSendMail.py
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
import json
def send_email(subject, html_message, from_email, to_email, smtp_info):
# 创建 MIME 对象
msg = MIMEMultipart()
msg["From"] = from_email
msg["To"] = to_email
msg["Subject"] = subject
# 添加 HTML 邮件正文
msg.attach(MIMEText(html_message, "html"))
# 连接到 SMTP 服务器
try:
server = smtplib.SMTP_SSL(smtp_info["server"], smtp_info["port"])
server.login(smtp_info["username"], smtp_info["password"])
server.sendmail(from_email, [to_email], msg.as_string())
server.quit()
return f"Email to {to_email} sent successfully."
except Exception as e:
return f"Failed to send email to {to_email}: {str(e)}"
def load_config(config_path):
# 加载配置文件
with open(config_path, "r", encoding="utf-8") as file:
config = json.load(file)
smtp_info = config["SMTP"]
email_content = config["EmailContent"]
recipients = config["Recipients"]
return smtp_info, email_content, recipients
config_path = "config.json"
smtp_info, email_content, to_emails = load_config(config_path)
from_email = smtp_info["username"]
# 发送邮件并打印每个发送的结果
for email in to_emails:
result = send_email(
email_content["subject"],
email_content["html_message"],
from_email,
email,
smtp_info,
)
print(result)
直接运行即可，用的库都是标准库，除非是精简版Python，否则都支持。
延迟发送
上面的脚本可以发送，但一次性发送太多可能会触发退信，被对方邮箱标记为垃圾邮件，所以添加随机延迟发送，修改后的代码如下：
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
import json
import time
import random
def send_email(subject, html_message, from_email, to_email, smtp_info):
# 创建 MIME 对象
msg = MIMEMultipart()
msg["From"] = from_email
msg["To"] = to_email
msg["Subject"] = subject
# 添加 HTML 邮件正文
msg.attach(MIMEText(html_message, "html"))
# 连接到 SMTP 服务器
try:
server = smtplib.SMTP_SSL(smtp_info["server"], smtp_info["port"])
server.login(smtp_info["username"], smtp_info["password"])
server.sendmail(from_email, [to_email], msg.as_string())
server.quit()
return True, f"Email to {to_email} sent successfully."
except Exception as e:
return False, f"Failed to send email to {to_email}: {str(e)}"
def load_config(config_path):
# 加载配置文件
with open(config_path, "r", encoding="utf-8") as file:
config = json.load(file)
smtp_info = config["SMTP"]
email_content = config["EmailContent"]
recipients = config["Recipients"]
return smtp_info, email_content, recipients
config_path = "config.json"
smtp_info, email_content, to_emails = load_config(config_path)
from_email = smtp_info["username"]
# 发送邮件并打印每个发送的结果，添加随机的延时
total_emails = len(to_emails)
for index, email in enumerate(to_emails, 1):
success, message = send_email(
email_content["subject"],
email_content["html_message"],
from_email,
email,
smtp_info,
)
print(f"Sending email {index}/{total_emails}: {message}")
if index < total_emails: # 如果不是最后一封邮件，等待随机时间
sleep_time = random.randint(0, 15) # 生成一个0到15秒之间的随机整数
print(f"Waiting for {sleep_time} seconds...")
time.sleep(sleep_time)
最后
阿里云邮件推送批量发送免费总额度是2000封，但日免费额度只有200，超过两百收费。脚本发送则没有限制，但是建议分批分时段发送比较稳定。
