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：

发送内容为纯文本的邮件 send_text()
发送内容为html格式的邮件 send_html()
发送包含多个附件的邮件 send_file()
发送混合的邮件 send_text_html_file()

代码

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；
