下面是我做到一个温馨小案例，每天给自己和朋友发送邮件，每天都会自动更新一句话和图片，让自己有个好心情。数据是从金山词霸接口得来的。
#!/usr/bin/env python
#-*- coding:utf-8 -*-
import yagmail
import requests
import urllib.request #py3中urllib2改成了urllib.requests
import os
yag = yagmail.SMTP(user='xxxxx@qq.com',password='xxxxx',host='smtp.qq.com',port='465')
url = "http://open.iciba.com/dsapi/"
r = requests.get(url)
body = r.json()['note']

image = r.json()['fenxiang_img']
name = image.split('/')[-1]
print(body)
path = "/opt/img"
if not os.path.exists(path):
os.mkdir(path)

s = urllib.request.urlretrieve(image,r'/opt/img//%s'%name)

#yag.send(to='xxxxx@qq.com', subject='测试邮件', contents=[body,'深圳政府采购接口测试.py'])

jpg_path = path+'/%s'%name

try:
yag.send(to=['2559567285@qq.com','429405037@qq.com','1028540310@qq.com'], subject='一封特殊的邮件', contents=[body,jpg_path])
except Exception as e:
print(e)
else:
print('邮件发送成功')
finally:
print('程序已执行')

当然数据还可以自己建文本自己弄数据，个性DIY自己的邮件。
