OP's service, as far as I understand, is a MITM proxy. The send emails using your credentials, not theirs.
So it can still act as a proxy for stolen Gmail, Outlook credentials or brute forcing passwords?
I would suggest rebranding if you just released it.
My theory is that LLMs will get commoditized within the next year. The edge that OpenAI had over the competition is arguably lost. If the trend continues we will be looking at inference like commodity prices, where the most efficient like cerebras and groq will be the only ones actually making money at the end.
