Use Standard Libraries smtplib and email

Below is a function for sending email leveraging standard libraries smtplib and email.

import smtplib
from email.mime.text import MIMEText


def send_email(recipient: Union[str, List[str]],
            subject: str,
            body: str = "",
            sender: str = "_sender_no_reply@domain.com",
            server: str = "smtp.server.domain.com"):
    """Send email.
    """
    mail = MIMEText(body, "html", "utf-8")
    mail["Subject"] = subject
    if isinstance(recipient, list):
        recipient = ";".join(recipient)
    mail["To"] = recipient
    mail["From"] = sender
    smtp = smtplib.SMTP()
    try:
        smtp.connect(server)
        smtp.send_message(mail)
        smtp.close()
        logger.info("The following message was sent: \n{}", mail.as_string())
        return True
    except:
        logger.info(
            "The following message was constructed but failed to sent: {}",
            mail.as_string())
        return False

notifiers

The function below is an example of sending email using the Python library notifiers.

import notifiers
notifiers.get_notifier("email").notify(
    from_="sender@domain.com",
    to=["recipient1@domain.com", "recipient2@domain.com"],
    subject="Example of Sending Email Using notifiers",
    message="This is a testing email.",
    host="smtp.domain.com",
    username="user_name_if_needed",
    password="password_if_needed",
    attachements=["/path/to/file1", "/path/to/file2"]
)

Notice that notifiers supports email attachements via the attachments option which accepts an iterable of valid file paths.
