The best AI email agent (2027): tools that handle your email, compared
Most “AI email” tools help you write faster. An email agent does the email for you. Here is the difference, and how the main tools compare.
Something Big Agent
It is a real agent, not a writing aid: it works in your Gmail or Outlook, reads what came in and replies as you, and it has its own computer and browser so it can finish the job in any website. You text or email it like a person who works for you.
