Minimal example:

import email.policy
import email.mime.text

responsehtml = "<html>somehtmlbody</html>"

msg = email.mime.text.MIMEText(responsehtml, "html", policy=email.policy.EmailPolicy())

msg["to"] = "test at example.com"
msg["cc"] = "äöü <foo at bar.com>"
msg["From"] = "foo at bar.com"
msg["Subject"] = "test"

msg.as_string()
