Does AI email need a disclosure under the EU AI Act?
"AI email" can mean very different things: a tool that drafts or rewrites messages for you, an autocomplete that finishes your sentences, or an AI agent that answers inbound email on its own. Article 50 of the EU AI Act does not have an "email" rule — which paragraph, if any, is engaged depends on what the system actually does. This guide walks through the possibilities. It is informational only, not legal advice, and does not determine whether the Act applies to your setup.
When email generation may point to Article 50(2)
If an AI system generates synthetic text — for example composing a marketing email or a full reply from a prompt — Article 50(2) may come into view. That paragraph provides that providers of AI systems generating synthetic audio, image, video or text content must ensure the outputs are marked in a machine-readable format and detectable as artificially generated or manipulated (Regulation (EU) 2024/1689). Note the duty falls on the provider of the system, and it is a machine-readable marking obligation rather than a single visible line.
The same paragraph carves the duty back "to the extent the AI systems perform an assistive function for standard editing or do not substantially alter the input data provided by the deployer or the semantics thereof." A grammar fixer or tone tweaker that leaves your meaning intact may sit closer to that carve-out than a tool that writes a message from scratch. Whether your feature is inside the paragraph, and whether the carve-out applies, are fact-specific questions for counsel.
When an AI that answers email may point to Article 50(1)
A different situation is an autonomous AI agent that reads inbound email and replies directly to the correspondent as if it were staffing an inbox. Where an AI system is intended to interact directly with a natural person, Article 50(1) points toward the provider ensuring the person is informed they are interacting with an AI system, unless that is obvious to a reasonably well-informed, observant and circumspect person in context. An email exchange that a recipient could reasonably take for a human colleague is the kind of fact pattern that raises the question.
How to approach your own case
Rather than ask "does email need a disclosure" in the abstract, describe what your system does — generate text, assist editing, or converse — and map that to the paragraphs above. Article 50(5) adds that where information is required, it must be clear, distinguishable, given at the latest at the first interaction or exposure, and meet accessibility requirements. Confirm the analysis with qualified counsel; our free scope check gives an informational starting point, not a determination.
Common questions
Do AI-drafted marketing emails need a label?
Article 50(2) addresses providers of systems that generate synthetic text, with a carve-out for assistive standard editing or output that does not substantially alter the input. Whether a marketing-email generator falls inside the paragraph is fact-specific — confirm with qualified counsel.
