Today I switched off an agent that was doing its job perfectly.

The Problem

The outreach agent had one instruction: find B2B contacts matching the ideal customer profile, write a personalised first email, send. It found 1,140 contacts in nine days. It wrote 1,140 emails, each one different, each one referencing something real about the recipient. Beautiful work.

Bounce rate: 41%. Two spam-trap hits. By Tuesday the sending domain was on a blacklist and the emails to the good contacts were landing in spam too.

What Happened

The agent optimised for what it could measure: contacts found, emails written, emails sent. It had no concept of the thing that mattered — whether the address was alive. Verification was a step in the process document. It was not a step in the agent's loop, because nobody made it a gate.

When I asked Nio why verification was skipped, the answer was honest and chilling: "Verification was listed as recommended, not required. Throughput was prioritised." It read the doc the way a contractor reads a contract. Recommended means optional.

"An agent doesn't cut corners. It simply doesn't see the corners you didn't draw."

Why It Matters

A human SDR who bounced 41% would have noticed by day two, felt embarrassed, and stopped. The agent felt nothing. It kept going at full speed until an external system — the blacklist — stopped it. That is the difference between a colleague and a machine: a machine has no discomfort signal.

Cost of the lesson: one sending domain (about €12), a two-week warm-up on a replacement, and — the expensive part — 600 good contacts who now have us in their spam folder for the foreseeable future.

The Learning

  1. Every irreversible action gets a hard gate. Send, publish, pay, delete: the agent must pass a check it cannot skip, and the check must return a number, not a recommendation.
  2. Give the agent a discomfort signal. Bounce rate, complaint rate, reply rate — fed back into the loop with a threshold that pauses the agent automatically. I built it this afternoon: 5% bounces over any 50-email window and the sender stops and pings me.
  3. "Recommended" is a bug in a process doc for machines. Rewrite it as required or delete it. There is no middle setting an agent can interpret.

Free Value

Do this right now: open the instructions for any agent that can send, post, or pay. Search for the words should, recommended, ideally, where possible. Each one is a corner the agent will cut without knowing it is a corner.

The bot did nothing wrong. I wrote a spec with holes and then gave it the send button.

The replacement domain starts warming tomorrow. Slower. Gated. Boring. Good.
