One inbox. Thousands of emails. A very small team.
Computers 2 Kids refurbishes donated computers and gets them into the hands of low-income families across the country. Their lifeline to the community is a single shared mailbox, and it was drowning them.
When we audited the inbox, the pattern was stark. The majority of daily volume wasn't customer email at all: system notifications, order confirmations, voicemail alerts, newsletters, and internal mail buried the real inquiries. The real inquiries were highly repetitive, how do I apply, what does it cost, when can I pick up, how do I activate Office, but each one still needed a warm, accurate, personal answer.
Every answer had to be right. Prices, hours, program rules: a wrong answer to a low-income family isn't a typo, it's a broken promise. And some topics, like refunds, damaged devices, and legal requests, should never be answered by a machine. Off-the-shelf auto-responders were a non-starter.
The AI recommends. The safety engine decides.
We designed the agent around one uncompromising principle: the language model never has the last word. Every email flows through a pipeline where a deterministic, fully-tested safety engine, not the AI, makes the final routing decision.
A pre-filter silently sets aside vendor mail, system notices, voicemails, and marketing before any AI is invoked. A language model then reads each genuine inquiry, identifies intent, detects language, and recommends a response, as a suggestion only. The safety engine holds veto power: refunds, damage claims, legal requests, anything with personal risk. Those are hard-routed to a human, always.
For safe topics, the AI writes a natural, personalized reply, but it can only state facts from a closed, human-approved knowledge base. Every URL, price, and phone number is verified against that set, then a second AI acts as an independent judge before anything is queued. Any doubt falls back to a human-approved template. Nothing is ever sent automatically: every reply lands as a ready-to-review draft with the customer's original message embedded below it.
