Easily send mails via SMTP and python
|
||||
|
||||
## Setup
|
||||
1. Copy `vars.py.example` to `vars.py`
|
||||
2. Setup `vars.py` with your credentials and config
|
||||
3. Adapt `message.htmt` and save your contact list to `contacts.csv`
|
||||
## Installation
|
||||
To install the requirements, run the following command
|
||||

|
||||
python -m pip install -r requirements.txt
|

## Usage

## 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'`
