2. Setup `vars.py` with your credentials and config ```
3. Adapt `message.htmt` and save your contact list to `contacts.csv` python -m pip install -r requirements.txt
```
## Usage ## Usage
```python mail.py```
### Setup
1. Copy `vars.py.example` to `vars.py`
2. Setup `vars.py` with your credentials and config

## Options
### Sending behavior
Some mail servers will block the requests, if too many are sent too fast. You can use the variables to add delays:
- `WAIT_EVERY` the amount of mails sent at once
- `DELAY_SEC` the amount of seconds to wait between sending the next batch
### Other options
- `LOGLEVEL` the logging level, set to `'DEBUG'` for most output
- `DRY_RUN` if set to `True`, the mails wont get sent, but the output is generated as if they would be sent. Good for testing and best to use with `LOGLEVEL = 'DEBUG'`
