之前分享过一期 smtplib发邮件踩过的坑；我感觉smtplib 用起来比较复杂，没那么好用，后来 我看到2个与发邮件相关的库 zmail、 yagmail，使用后有些心得，在此做个分享。

需求

本篇主要是讲述 4个方法：

  1. 发送 内容为纯文本的邮件 send_text()
  2. 发送 内容为html格式的邮件 send_html()
  3. 发送 包含多个附件的邮件 send_file()
  4. 发送 混合的邮件 send_text_html_file()

                yagmail.inline(html)]

    # Gmail 会将附件的HTML 作为 正文
    # 是因为yagmail库message.py prepare_message()中的代码：
    # # merge contents and attachments for now.
    # if attachments is not None:
    #     for a in attachments:
    #         if not os.path.isfile(a):
    #             raise TypeError("'{0}' is not a valid filepath".format(a))

    email.send(to=receiver, subject=subject, contents=contents, attachments=file_list, cc=cc)
    print('邮件发送成功 {}'.format(n))
    email.close()

实际结果

实际不同邮箱 收到相同邮件时 正文内容、附件内容【文件名、文件是否存在】、邮件数量 有不同；

这一部分 不打算分享；我现在无法确定 相同邮件不同结果 到底是什么原因。

关于发邮件的分享到此为止；
