Python tool to monitor competitor domains for expiry and send alerts via email.

Features

• Reads domains from a text file (one per line)
• Supports domains with/without http/https/www

  pip install python-whois
  

Usage

Prepare a listdomain.txt with one domain per line:

https://anotherdomain.net

Run:

python main.py \
  --domains listdomain.txt \
  --alert-days 30 \
  --notify-from you@example.com \

  --smtp-server smtp.gmail.com \
  --smtp-port 587 \

  --smtp-pass yourpassword

Example:

Check domains that expire within 30 days and send email:

python main.py --domains listdomain.txt --alert-days 30 \
--notify-from admin@me.com --notify-to boss@me.com \
--smtp-server smtp.mailtrap.io --smtp-port 587 \
