Questions

My send is rejected as an unknown sender

Brevo only sends from a sender you have added and verified. Add the address or the domain before using it as the from field.

Is this the same as the SMTP credentials?

No. These scripts use the HTTP API with this key. Brevo's SMTP login is a separate credential, which belongs in an smtp resource instead.

Is my key stored on the hub?

Never. It lives only in your own Windmill workspace, encrypted at rest.
