CTEmail is a Charts and Text Email script, which can send email with chart pictures in email content body not email attachment.

Here is a tutorial in Chinese

Why make this tool?

• As a programmer, we hope to complete everything automatically by scripts, such as send report email daily.
• In business, we cooperate with some friends. Sometimes we exchange the report with data, where we can use charts and suitable text to display.
• We can find some pictures in some emails, but those pictures are manual and the email is also manual.
• These are all things that we needs.

Who can use it?

• Product manager, CTEmail is one of the best practices!
• Operating Officer, CTEmail is one of the best practices!
• Programmer, everything is automated!

Requirement

• Python：Python2(You can also use Python3 with similar code!)
• PlotlyA tool for displaying your data. It supports offline and online modes. You can read the documents from the website.

Project structure

├── README.md
├── content
│   ├── image1.png
│   ├── image2.png
│   └── index.html
├── ctemail.py
├── get_img.py
└── send.py

• Under the content folder, you will see the index.html file, which is the content of email. Also this folder include the images(charts) resources.
• ctemail.py is the CTEmail class written by Python script.
• send.py is the script to send email and configures of email account.
• get_img.py can generate the chart images by plotly.

Installation

First Step:

git clone git@github.com:dyike/CTEmail.git

Second Step:

Config the send email scprit:

from ctemail import CTEmail
e = CTEmail('Your email acount', 'Your password')
# " ./content/ " is the email path 
e.send_email('Test Email', './content/', ['i@ityike.com'])

Third Step:

Deal with the data, then generate the chart images.

Also we can add some code to generate the conten/index.html file.

Here is a demo:

import plotly.plotly as py
import plotly.graph_objs as go

py.sign_in('Your account', 'API Token') # Configure your username and api key token

trace = go.Bar(x=[2, 4, 6], y= [10, 12, 15])
data = [trace]
layout = go.Layout(title='A Simple Plot', width=800, height=640)
fig = go.Figure(data=data, layout=layout)

py.image.save_as(fig, filename='./content/image.png')

Fourth Step:

In the email template file, you will see the <EMAIL_IMG> tag. It is essential! The script will find the tag to parse. If you want to add two or more images, you should do as follows:

    <a><EMAIL_IMG><img src="image1.png"></EMAIL_IMG></a>
    <a><EMAIL_IMG><img src="image2.png"></EMAIL_IMG></a>

Fifth Step:

Send email!

python send.py

then, you will received email!
