What an AI email assistant does

Beyond writing individual messages, these assistants manage the whole inbox. They triage incoming mail by importance, summarise long threads so you catch up fast, draft context aware replies, and handle repetitive responses. Some work right inside your email client, so the help is where you already are.

What to look for

  • Reply quality and whether it understands the thread.
  • Inbox triage that sorts and prioritises well.
  • Summaries of long threads to save reading.
  • Integration with your email provider for speed.

How to choose

Decide whether you mainly need help writing or help managing. For writing, prioritise reply quality and tone. For inbox overload, prioritise triage and summaries. Integration with your email client matters for both. Consider privacy, since these tools read your mail, and test on a busy day to judge the benefit.

Getting the most from it

Let the assistant handle the routine volume while you keep the important and sensitive messages personal. Review drafts before sending, since tone in email matters, and set clear preferences so triage matches how you actually work. A little setup up front turns it into a tool you genuinely rely on.
