我们有一个python脚本,每天将邮件发送到xml地址列表.这些邮件始终被Gmail标记为垃圾邮件.这是代码：email_body = '

'

#text corresponding to that subcription date

# email

msg = MIMEMultipart('alternative') #Create Multipart msg (allows html)

msg['To'] = email.utils.formataddr(('Recipient', 'readers@traces.net'))

msg['From'] = email.utils.formataddr(('Traces', 'traces@anemailstory.net'))

msg['Subject'] = 'Tr@ces - Part #' str((i 2))

part_html = MIMEText(email_body, 'html')

msg.attach(part_html)

server = smtplib.SMTP('localhost')

server.set_debuglevel(False) # show communication with the server

try:

server.sendmail('traces@noreply.net', email_addrs, msg.as_string())

finally:

server.quit()

这是生成的电子邮件：Return-path:

你对此有什么解决方案吗？

谢谢.

解决方法:

您的电子邮件几乎只包含HTML和链接.闻起来像垃圾邮件.

建议：

>发送明文电子邮件(不太可能被视为垃圾邮件 – 对许多用户来说更舒适)

>如果您使用HTML,请始终包含纯文本版本

>改善文本到链接/ HTML比率.来源：https://www.icode9.com/content-1-356151.html
