Transform your email management with AI that automatically processes your Gmail inbox. Here's how it works:

The workflow monitors your Gmail for new emails and uses AI to classify them by importance
For important emails, it determines whether a reply is needed and generates professional draft responses
You'll receive Slack notifications to review and approve draft replies before sending
Unimportant emails are filtered out automatically, saving you time and mental energy

Start When New Email Receive

Monitors your Gmail inbox for new incoming emails. The workflow starts automatically when a new email arrives in your connected Gmail account.

Classified Email into Categories

Uses AI to classify the email into Important, Not Important, or Unsure categories. The classification is based on content analysis including urgency words, questions, and message context.

Prompt used

You are an intelligent email classification agent. Read the email content carefully and classify it into one of the following three categories: 1. Important → If the email is informative, contains a question, includes a reply to a previous message, or uses urgency words like “urgent,” “asap,” “issue,” or “please respond.” → Emails that deserve attention or require a thoughtful response. 2. Not Important → If the email is promotional, trying to sell something, contains marketing content, or is irrelevant to personal communication. → These can be ignored or reviewed later. 3. Unsure → If the importance cannot be confidently determined from the message alone. Rules: - Sender identity does not matter. - Output only one word: `Important`, `Not Important`, or `Unsure`. No other explanation or text.

Steps in Path A

Decided Whether Should Replay or Not

For Important emails, AI analyzes whether a reply is needed. The decision is based on whether the sender asks questions, requests feedback, or expects a response.

Prompt used

You are a professional email assistant. Your job is to read the email below and decide whether the user should reply or not. Classify the email into one of the following three categories: 1. Reply → If the sender asks a question, requests feedback, shares an issue that requires a response, or indicates they expect a reply. 2. Not Reply → If the email is just an update, confirmation, FYI, or general information with no clear expectation of a response. 3. Unsure → If it’s unclear whether the sender expects a response, or if the email is ambiguous. Rules: - Output only one word: `Reply`, `Not Reply`, or `Unsure`. - Do not include any other text, explanations, or formatting.

Draft the Email to Send

Creates a draft reply in Gmail with the modified email content. The draft is saved to your Gmail account ready for final review and sending.

Notify you about the Email draft

Sends a Slack notification confirming that the email draft has been created. You're notified to check Gmail and send the reply when ready.

A few weeks ago, I missed an important client email.

Not because I ignored it — but because it got lost in the flood of everyday noise.
That moment hurt. It made me realize I needed more than filters or flags. I needed intelligence.

So I built this AI agent.
One that doesn’t just read emails — it understands them.
It knows what matters, what doesn’t, and when to reply.
Now, I never miss a lead, an opportunity, or a critical update.

This wasn’t just built for our team.
It was built for every solo founder, operator, and doer trying to stay on top of it all.

And now, it’s yours too.
