def send_register_email(email, send_type="register"):

    email_record = EmailVerifyRecord()
    code = random_str(16)  # 16位长的随机字符串
    email_record.code = code
    email_record.email = email
    email_record.send_type = send_type
    email_record.save()

    if send_type == "register":
        email_title = "在线教育网站注册激活"
        email_body = "<h3>请点击下面的链接激活你的账号:</h3> <a>http://127.0.01:8000/active/{0}</a>".format(code)

        send_status = send_mail(email_title, email_body, EMAIL_FROM, [email])  # email是收件邮箱   发送成功会返回true
        if send_status:
            return True
        else:
            return False

发送结果如下

email_body 如果想发送有效的 html 格式 怎么改？我想要让链接 像html一样的样式
