An AI email assistant for your business inbox.
Nerb’s AI Email Assistant works in your shared Gmail inbox for Singapore businesses. It sorts each new email, drafts replies from your own prices and policies, follows up on quotes and holds suspected payment scams for a person to check.
How does the AI Email Assistant work?
It reads each new email in your shared Gmail inbox, sorts it and drafts a reply from your approved business information. It sends automatic replies only for the email types you choose, once you switch them on. Nerb sets it up in three steps.
Connect your inbox
enquiries@, sales@ or accounts@ on Google Workspace, with permission to read, label and draft. Microsoft 365: coming.
Load your business knowledge
Your prices, services, policies and good past replies. You approve what the agent may use.
Set the rules
Choose which emails it drafts and who each type goes to. It starts on drafts only.
What does the AI Email Assistant do with each email?
It labels every new email, then drafts a reply, sends one, passes it to a named person, holds it as suspicious, or files it. It sends only for the email types you choose, once you switch them on.

5 ideas for your year-end promotion

This week: planning year-end promotions, plus a checklist for your Google Business Profile.
Sample business, not a client. Automatic replies are on for receipts here. Try approving Priya’s quote; the second email shows a reply drafted in Chinese.
Can the AI Email Assistant send emails on its own?
Only if you switch it on, and only for the email types you choose. Until then, every reply waits as a draft for your team to approve. Complaints and payment requests always go to a person.
New enquiry acknowledgements
A short “we’ve received your message” with your reply times.
Price and service questions
Answered from your approved price list and FAQs.
Quote requests
Drafted from your current price list, with GST shown.
Booking requests and changes
Open slots offered from your team calendar.
Receipts and invoice copies
Sent from your accounting records.
- Always a person
Complaints
Passed to a named person with the email history attached.
- Always held
Payment or bank-detail changes
Held and flagged to the owner.
Nothing sends automatically. 5 wait as drafts for a person to approve, 1 goes straight to a person, and payment changes are always held.
Approval checkpoints like these are in line with the human-oversight practices in IMDA’s Model AI Governance Framework for Agentic AI (January 2026, updated May 2026).
How does it make sure quotes get a reply?
It tracks every unanswered quote and drafts a polite follow-up after the days you choose. When the customer replies with a time, it offers open slots from your Google Calendar for your team to confirm.

Can it spot payment scams?

It flags these emails and holds them. Requests to change bank details, urgent transfers and look-alike supplier addresses are kept out of the reply queue and passed to the owner. The agent never pays or changes a record because an email asked it to.

How is it different from the AI built into your email app?
Built-in AI helps each person write their own emails. The AI Email Assistant runs a shared business inbox, knows your prices and policies, and follows your send rules.
| AI built into your email app | Nerb AI Email AssistantNerb AI Business Platform | |
|---|---|---|
| Works on | Each person’s own inbox, when they ask | Shared Gmail inboxes such as enquiries@, on every new email (Outlook: coming) |
| Knows your business | What’s in the mailbox or a prompt | Your approved prices, policies and past replies |
| Replies | Suggests text for a person to send | Drafts every reply. Sends only for the email types you choose, once you switch them on |
| Follow-ups | Up to each person to remember | Tracked for every unanswered quote |
| Payment-change emails | Built-in spam and phishing filters | Also checked against your supplier records and held for the owner |
| Set up by | You | Nerb, in Singapore, with a monthly check of its work |
If you mainly want help writing your own emails, the AI built into your email app may be all you need. The AI Email Assistant is for customer emails that arrive in a shared inbox and need a consistent, timely answer.

AI email assistant: questions, answered
What Singapore business owners ask before letting AI into the company inbox.
It drafts only from the knowledge you have approved and shows which items it used. With no approved answer, it passes the email to a person instead of guessing.
Yes. It replies in the customer’s language, such as English, Chinese or Malay, from the same approved information. Drafts can be reviewed before sending.
It helps. With Google Calendar connected, it drafts a reply offering open slots, and your team confirms the booking. Outlook calendar: coming.
Only your own. Your emails train the AI in your own Nerb AI Business Platform, so it learns how your business replies. That learning stays in your platform.
Yes, at any time. Pause the agent, switch automatic replies off, or remove its access on Google’s permission screen. Your emails stay in your inbox.
The people you choose. Drafts wait in the Gmail thread for anyone with access to that inbox to edit and send, and each email type can go to a named person. Every action is logged.
