Sending email with Workmail via Python

Question

I'm trying to send email via Workmail using Python
```
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase

def send_email(email_recipient, email_subject, email_message):
    try:
      server = smtplib.SMTP_SSL('smtp.mail.eu-west-1.awsapps.com', 465)
      server.ehlo()
      server.login('username', 'password')
      text = msg.as_string()
      server.sendmail(email_sender, email_recipient, text)
      print('Email sent to %s' % email_recipient)
    except Exception as e:
      print(e)
      print("SMTP server connection error")
    return True

def main():
  send_email('email@domain.com', 'hello', 'world')

main()
```

This does not work because 
```
(535, b'Authentication credentials invalid')
SMTP server connection error
```

But using `username` and `password`, I am able to log into https://webmail.mail.eu-west-1.awsapps.com/workmail/ with these credentials.

So my questions are 
1. Is it possible to send an email using the SMTP server of Workmail. 
2. If yes, why are those credentials invalid (I also tried base64)

Many thanks in advance!

As mentioned by John (of AWS) above, use full email address for SMTP.

However please note that Workmail shouldnt be use for bulk emails and its primary use case would be Employees of a given company need to email each other on their company email addresses (and to some extent their individual partners).

Check also SES service incase its a better fit.
