According to google smtp codes this is the explanation
530, "5.7.0", Must issue a STARTTLS command first.

same problem here

The documentation is actually misleading:
STARTTLS is not supported by the action.

See: https://github.com/search?q=repo%3Adawidd6%2Faction-send-mail+starttls&type=code

• with smtp:// the action opens a plaintext SMTP connection and optionally upgrades it with STARTTLS (if supported by the server)
• with smtp+starttls// the action directly opens a SMTP connection over TLS (without issuing a STARTTLS command first)

Thus it is possible to use STARTTLS (using a smtp:// url), but you cannot require it.
