How to Make an AI Answer Your Emails While You Sleep

Last updated: March 30, 2026

You close your laptop at 10 PM. By 7 AM, 23 emails are waiting. Half are questions you've answered before. A quarter need a simple "yes, here's the link." A few need real thought. An AI email agent handles the first 80% so you wake up to a clean inbox instead of a backlog.

Tommy.app is an AI agent platform that gives you a personal assistant on Telegram — and answering emails overnight is one of the things it does best. One business owner had 47 emails answered while they slept. Here's exactly how to set it up.

How does an AI email agent actually work?

An AI email agent connects to your inbox, reads incoming messages, understands what each person is asking, and writes a contextual reply in your voice. It's not a template system or auto-responder — it reads and thinks about every email individually.

Tommy.app agents use Claude AI to understand context, tone, and intent. When a customer asks "do you offer weekend appointments?", the agent doesn't send a generic FAQ — it replies naturally: "Yes! I have Saturday slots available at 10 AM and 2 PM. Would either work for you?"

The agent also remembers previous conversations. If someone emailed last week about pricing and follows up today, your agent picks up where you left off. No "per our last email" — it genuinely remembers.

What do I need to set up AI email replies?

You need three things: a Tommy.app account ($1 for a 3-day trial), a Telegram account (free), and access to your email account credentials. That's it. No servers, no API keys, no coding.

Here's the step-by-step process:

1. Sign up at tommy.app — start the $1 trial, name your agent, and pick the business assistant template.
2. Connect your email — tell your agent in the Telegram chat to connect to Gmail, Outlook, or whichever provider you use. It walks you through authorization in about 30 seconds.
3. Train your voice — paste 5-10 example emails you've actually sent. Tell the agent things like: "I'm friendly but professional. I always offer a free consultation. I never discuss exact pricing over email — I redirect to a call."
4. Set your autonomy level — choose draft-only (you approve everything), auto-send (fully autonomous), or hybrid (routine emails auto-send, flagged ones wait).
5. Let it run — your Tommy.app agent monitors your inbox around the clock and handles replies based on your rules.

The entire setup takes under 2 minutes. Most of that time is pasting your example emails.

How do I make sure the AI sounds like me?

Voice training is the most important step. Tommy.app agents learn your patterns from the examples you provide — your sentence length, vocabulary, level of formality, and even your quirks (like always starting emails with "Hey" instead of "Hello").

Here's what to include in your training:

• 5-10 real email replies you've written (variety of topics helps)
• Explicit rules — things you always do ("always mention our free trial") or never do ("never promise a delivery date")
• Common scenarios — your standard reply to pricing questions, support requests, meeting scheduling
• Escalation triggers — what should get flagged to you personally (complaints, large orders, legal questions)

After the first few replies, review them and give feedback. Tell the agent "that was too formal" or "I'd never use the word 'utilize' — say 'use' instead." Tommy.app agents improve with every correction.

What types of emails can an AI agent handle?

Tommy.app agents handle the repetitive 80% of your inbox reliably. The remaining 20% gets flagged for your attention.

How is this different from Gmail smart reply or canned responses?

Gmail's smart reply gives you three generic one-liners: "Thanks!", "Sounds good!", "I'll look into it." Canned responses are templates you manually trigger. Neither reads or understands the email.

A Tommy.app agent reads the full email, understands what's being asked, considers your past conversations with that person, and writes a unique, detailed reply in your voice. It's the difference between a voicemail greeting and an actual conversation.

Can I review emails before the AI sends them?

Yes — Tommy.app agents support three autonomy levels, and you choose which one to use. Most people start cautious and gradually increase trust.

Draft mode: The agent writes every reply but doesn't send anything. You get a Telegram notification with the draft and approve, edit, or reject with one tap. Best for your first week.

Auto-send mode: The agent handles everything autonomously. You get a morning summary of what was sent. Best once you trust the agent's voice and judgment.

Hybrid mode: Routine emails (scheduling, FAQs, simple follow-ups) auto-send. Anything unusual, high-value, or flagged waits for your approval. This is what most business owners land on.

What does a morning summary look like?

Every morning, your Tommy.app agent sends a summary to your Telegram with exactly what happened overnight. It includes: how many emails were received, how many were answered, which ones were flagged for your review, and any patterns it noticed (like a spike in questions about a specific product).

You review the flagged emails right from Telegram — respond, approve drafts, or give the agent updated instructions. The whole morning review takes 5 minutes instead of the 45 minutes you'd spend manually clearing your inbox.
