AI assistant for email — triage, drafts, and follow-through

Email is where work goes to queue. The median inbox mixes three genuinely important threads with forty that need a two-line reply, a forward, or nothing — and the owner pays a tax on all of them, every day, deciding which is which. An AI assistant for email removes that tax: it reads what arrives, surfaces what actually needs you, drafts what doesn't, and keeps the follow-ups alive that you'd otherwise lose.

The distinction that matters in 2026 is between inbox tools and colleagues that handle email. Inbox tools live inside Gmail or Outlook and stop at the inbox's edge. An AI colleague like Arlo treats email as one surface of a bigger job — because half of "email work" isn't email at all. The reply needs a number from the CRM. The intro needs a calendar hold. The vendor thread needs someone to just call.

What Arlo does with your inbox

• Triage — reads incoming mail and sorts it into needs-you, needs-a-reply-it-can-draft, and noise. What needs you arrives as a short note in the channel you actually check: iMessage, Slack, or WhatsApp.
• Drafts in your voice — replies sound like you because Arlo remembers how you write, who the sender is, and what happened in the thread last month.
• You see its drafts first — a reply Arlo writes comes to you before it reaches someone who hasn't seen it, unless you tell it to just send. A clear "send it" goes out. See when Arlo asks first.
• Follow-ups that don't die — the intro you never answered, the invoice at day 30, the trial that went quiet. Arlo tracks open loops and nudges or chases on schedule.
• Beyond the inbox — the same request can read Gmail, update the CRM, drop a summary in Slack, and schedule the call. One colleague, 3,000+ tools, one audit trail.

A day with it

Morning: one briefing in your texts — what came in overnight, what Arlo already drafted, the two threads that genuinely need you. You reply "send 1 and 3, hold 2." Midday: a customer asks for pricing; Arlo drafts from the current sheet, you approve from your phone. Afternoon: it flags that the Hendricks invoice hit day 30 and asks whether to chase by email or just call — and if the answer is call, it makes the call and reports back. None of this required opening the inbox.

Dedicated inbox tools are good at the inbox; if that's the whole job, they're worth a look — we keep an honest map in Fyxer alternatives. The case for a colleague is everything the inbox touches.

Getting started

Connect Gmail, tell Arlo what matters ("investor threads and anything from these five domains come to me; draft the rest"), and tell it to ask before every send the first week. Trust is earned by watching the drafts. Most people let routine replies go out within days and keep Arlo asking on anything customer-facing — which is exactly how it should work.

When the inbox in question is a shared support queue rather than your own, the triage rules change — see AI assistant for customer support.

Frequently asked questions

What is an AI assistant for email? An AI that triages your inbox, drafts replies in your voice, chases follow-ups, and files noise — ideally showing you its drafts before they go and keeping an audit trail after. Arlo does this as one channel of a broader AI colleague.

Will it send emails without my permission? Only what you clearly ask it to send. A reply Arlo drafts comes to you first unless you tell it to just send, and you can tell it to always ask before certain emails. Every send is logged either way.

How is this different from Gmail's built-in AI? Native suggestions help you write faster inside the inbox. An AI colleague works the inbox for you — from your texts or Slack — and carries tasks beyond it: records, schedules, calls.

Can it handle more than one email account? Arlo connects to Gmail among 3,000+ tools; for multiple accounts and other providers, check the in-product integrations list for current coverage of your setup.

Does it work with Outlook? Arlo connects to 3,000+ tools including major email providers; check the integrations list in the product for current coverage of your stack.
