Customize a scheduled email report

A python template to help you get a custom email report up and running.

The repository is set up in a modular fashion so you can easily substitute in your own email address and report contents. I have personally found this to be a fun use for custom web scrapers that grab information off the internet and add it to an email report I have sent to myself every morning.

What is in the repository? - This is the executable file that will initiate the message composition and send the email.

message folder:

How do I make it work?

To get the report up and running there are a few steps you need to follow:

1. You need an email account to send the email report from

  • I recommend signing up for a new gmail account for this purpose. You must allow unsecure access on the account (a no no for your main email!)
  • After you get a new gmail, go to the 'sign in and security' page and toggle the 'allow less secure apps' option to ON. This lets the python script send an email through the account.

2. Open

  • On line 11 change the string to the email address you will be sending FROM.
  • On line 12 put the password for the sending email address.
  • On line 13 put the email address you are sending the message TO. NOTE: If you didn't use gmail, you must change the server name on line 33 to match your email host. Just google 'hostname smtp server' and you can figure this out easily.

3. Figure out what you want in your report!

  • Write some modules to scrape data from the web, provide you with links to interesting news articles, or whatever else you would like!
  • Write the code in functions so that they can be imported into the file and run automatically.
  • When you write these modules, place them in the message folder.
  • I have included two example modules for inspiration. Information on what they do can be found in posts here and here.

4. Link the report functions to the file

  • This file is called to build the body of the message for the email. It imports the other modules in the message folder and calls the needed functions.
  • There are annotations within the file to help you import and run your custom functions.

5. Test it out

  • You will likely need to tweak the message contents to get it looking how you want.
  • A few test calls of will show you the output and help with spacing, newlines etc.
  • You can add new modules and import them into whenever you like, so you can easily change the report over time.
  • After setup, all you need to run the program is:

6. Run it automatically

  • You can set the message up to auto send.
  • On mac/linux the easiest way to do this is cron
  • from command line type crontab -e
  • then add a command to schedule execution. For example: to send the email report at 6am on Monday-Friday on my computer I add the command: 0 6 * * 1-5 python /Users/Cam/bin/
  • Here is the general syntax for scheduling the job so that you can get it running at the time you want:
*     *     *   *    *        python ./
-     -     -   -    -
|     |     |   |    |
|     |     |   |    +----- day of week (0 - 6) (Sunday=0)
|     |     |   +------- month (1 - 12)
|     |     +--------- day of month (1 - 31)
|     +----------- hour (0 - 23)
+------------- min (0 - 59)
  • If you want to get really fancy then set the program up to run in the cloud (on Amazon Web Servies, Google cloud etc.) and then you will be sent the report even if your computer is off.

Thats it! A simple template for a custom email report. Feel free to take this and use it yourself! I would love to hear about any interesting scrapers or data aggregation modules that you construct and run in this template.


The example web scraper uses the beautiful soup package. Besides that the repository is all python3 standard library. You can download beautiful soup using: pip install bs4
