I am building a technical x-ray for 2026 deliverability

I just launched the first version of InboxGuard because I was tired of great cold emails hitting the 'Spam Trap' despite doing everything right.

In 2026, Google uses AI to flag 'Broadcast Tone' that builders cannot see. I am building this in public at $0 MRR to help this community protect their domain reputations before they hit send.

I would value your raw feedback on the 'Risk Engine' and I am turning deliverability from a guessing game into a science.
