• Usage
• API

Littlemail is a straight-forward command-line SMTP email sending tool in Python, which sends one email per command. (If you send many emails, every sending will make a new connection with the smtp server.)

Installation

$ pip install littlemail

Usage

There is no way to reduce parameters provided in command-line, since that's the way of email. So, please refer to the inline help for options you need. Fortunately, many options have default value.

$ python -m littlemail -h  # inline help

Anyway, here is a minimal example and a few lines of explanation:

$ python -m littlemail -s test [-c hello] \
                -f 12345@qq.com \
                --to 54321@qq.com \
                --smtp smtp.qq.com [-p abcdefg]

-c means the email content, which is optional. That means you can send empty-content email. And this optional parameter enables the capability of littlemail to get content from pipe (input redirection), which might be easier for you to construct your message, such as:

$ python -m littlemail <...> < my_email_content.txt

-s represents subject, which is mandatory and cannot be empty.

-p stands for password, and it is optional. When it's missing, littlemail tries to get password from LITTLEMAIL_PASSWD environment variable.

When something goes wrong, try --debug.

API

There is an API you can invoke to send email in your code:

# import
from littlemail import send_email
# signature
def send_email(subject: str,
               *,
               text: str = '',
               contype: str = 'plain',
               alist: list[str] = [],
               to: list[str],
               cc: list[str] = [],
               bcc: list[str] = [],
               fromaddr: str,
               smtp: str,
               port: int = 587,
               timeout: int = 3,
               protocol: str = 'tls',
               passwd: str|None,
               debug: bool = False) -> None: ...

api_test.py is used as an example and testcase for you to try, have fun! ^___^
