This is a simple Flask App to send HTML Emails written in Python3. Set up a virtual environment with a Python3 interpreter. Install dependencies with pip install -r requirements.txt. Copy config.py.example into a new config.py file.
Use python manage.py generate_secret to generate a new secret. Set SECRET_KEY in config.py to this newly generated key, or any other key you want. It's used as salt to generate the csrf token.
