Antitrust Risk in Everyday Emails: The Language That Triggers Competition-Law Liability

June 22, 2026 · 4 min read

Two competitors share a stage at an industry panel. They agree on more than they expected, and a week later one sends the other a warm follow-up email. Somewhere in that friendly note is a single sentence that, if a regulator ever reads it, could cost both companies a fine measured in millions and cost one of the executives a criminal record.

That is the uncomfortable truth about antitrust risk. It rarely looks like a smoke-filled-room conspiracy. It looks like an ordinary email between two people who have known each other for years.

🔬 The penalties are not theoretical. Under EU competition law, a company can be fined up to 10% of its total worldwide annual turnover for a single infringement. In the United States, price-fixing, bid-rigging, and market allocation are criminal offences under the Sherman Act, carrying corporate fines up to $100 million (or twice the gain or loss involved) and up to 10 years in prison for individuals.

Sources: EU Regulation 1/2003, Article 23; US Sherman Antitrust Act, as amended by the Antitrust Criminal Penalty Enhancement and Reform Act.

Regulators build these cases on words. Internal emails, chat messages, and meeting notes are the evidence. Which means the risk lives exactly where most companies are not looking: in the outbound message, at the moment it is written.

What email language creates antitrust risk?

Antitrust risk is not ordinary competition. It is an agreement, an invitation, or an understanding between rivals to soften competition. A few categories cover most of it:

  • Price fixing or alignment: “let’s not undercut each other”, “there’s no sense in racing to the bottom on price”, “let’s both hold our rates”.
  • Market or customer allocation: “you take the north, we’ll take the south”, “that account has always been yours, we’ll stay out”.
  • Bid-rigging: “put in a high cover bid”, “we’ll return the favour next tender”.
  • No-poach or wage-fixing: “let’s agree not to hire each other’s staff”, “we won’t go after your people if you don’t go after ours”.
  • Information signaling: telling a competitor your future prices, capacity, or bid range before you both quote.

What is not antitrust

Plenty of competitive language is completely legal, and treating it as risky just creates noise. The following are normal business:

  • Unilateral competition aimed at winning: “let’s beat them on price”, “sharpen our quote”.
  • Benchmarking a competitor’s publicly available prices or information.
  • Coordinating with a non-competitor (a supplier, partner, or customer) on schedules or a joint launch.

The trigger is always coordination with a rival to dampen competition, never ordinary rivalry.

Why it hides in everyday emails

The dangerous version is rarely blunt. It is phrased as shared wisdom or a market observation: “the whole category breathes easier if we let it”, “a bit of pricing discipline helps everyone”, “no point both of us competing on this”. The softer the wording, the easier it is to send without a second thought, and the softer wording is exactly what regulators quote back in the decision.

Catching it before it leaves the outbox

Unlike most communication risks, a coordination proposal has no compliant rewrite. You cannot soften “let’s not compete on price” into something safe, because the meaning itself is the problem. The only real fix is to catch it before it is sent and remove it.

This is where real-time, pre-send detection matters. VerbaPulse reads a message as it is written, flags antitrust language the moment it appears, names the specific risk (price fixing, allocation, no-poach, signaling), and prompts the writer to remove it. Compliance sees patterns at the department level, without reading individual emails.
