How to Identify AI-Generated Emails Before They Reach Your Inbox

With more than 6.7 billion AI-generated emails now sent every day, recognising artificial writing has become easier—and more important—than ever. Experts say nearly 70% of partnership and outreach emails are already written by AI, flooding inboxes with messages that look polished but feel impersonal. To cope, many companies are deploying detection systems that filter AI-generated text, saving teams up to 1–1.5 hours daily in email triage.

One of the clearest signs of AI writing is overly formal greetings. Phrases like “Dear Sir or Madam” or “I hope this message finds you well” are used far more frequently by AI than humans. While polite, they sound generic and detached. Using a real name and getting straight to the point creates more authenticity.

Another red flag is the excessive use of transition words such as “moreover,” “furthermore,” and “additionally.” AI tends to over-explain, making messages feel mechanical rather than conversational. Natural writing flows without announcing every transition.

AI emails also rely heavily on scripted supportive language. Expressions like “kindly let me know” or “don’t hesitate to reach out” appear almost three times more often in AI-generated content, making them easy to spot.

Experts advise training AI tools on your own writing style and always editing before sending. As email volumes rise, authenticity—not automation—remains the key to avoiding “soft spam.”
