Why are you using email.mime instead of email.contentmanager?

BRILLIANT! I can send an email.....thank you very much Smile

However there is one issue still remaining - my html is not being rendered. This is what the email looks like in Thunderbird email client:

   

So what am I still doing wrong?

    msg['From'] = Address("Find a Tradie", "find-a-tradie", "outlook.com")
    strToEmail = strToEmail.replace("\n", "")
    arrayParts = strToEmail.split("@")
    msg['To'] = Address("Fellow Tradie", arrayParts[0], arrayParts[1])
    msg.set_content("""\
