Email Tracker allows you to send emails and track those emails to see if they were opened or not. If they were opened, you can see their IP address (and hence rough location), user agent, device etc.
When the send_mail.py sends an email, it embeds a 1x1 gif into the mail which is hosted on my webserver (using nginx).
The name of the gif is the same as the target's email address, so, we can get the relevant information from nginx's logs, which is what check_activity.py does.
Both the scripts require no external dependencies and will run out of the box with python3.
Apart from the scripts, you need to have nginx installed and running.
For check_activity.py to parse information from nginx logs, you'll have to change the log_format option in /etc/nginx/nginx.conf.
log_format myformat '$remote_addr,$time_local,"$request","$http_referer","$http_user_agent"';
accesslog /var/log/nginx/access.log myformat;
After setting up nginx as mentioned above, clone this repo:
git clone https://github.com/mananapr/email-tracker
Then copy the files to the webroot:
cp -r email-tracker/* /var/www/html
To manipulate files within the webroot, change the permissions:
sudo chown -R "$USER":www-data /var/www/html
sudo chmod -R 0755 /var/www/html
Now you can use send_mail.py to send mails and check_activity.py to track the sent mails.
Make sure that you change the variables in both the scripts according to your setup.
This video shows me using the scripts. I checked the mail on my phone, so it shows my Phone OS version and IP Address.
