AI Scheduling Agent with Email

Scheduling meetings is one of the most tedious tasks in professional life. Coordinating availability across multiple participants, accounting for time zones, handling last-minute changes, and sending confirmations can consume hours of back-and-forth email. An AI scheduling agent eliminates this friction entirely by managing the entire coordination process via email -- the same channel people already use to request and confirm meetings.

Unlike calendar link tools that require participants to visit an external website, an email-based scheduling agent meets people where they already are. A participant can simply reply "I am free Tuesday afternoon or Thursday morning" and the agent handles the rest. AgentSend provides the email infrastructure that makes this natural, conversational scheduling possible.

How AI Scheduling Agents Work with Email

A scheduling agent powered by AgentSend operates through a series of email exchanges that mirror how a human assistant would coordinate a meeting. The process is natural for participants because they just reply to emails -- no apps to install, no links to click.

Receiving a Scheduling Request

The workflow starts when someone emails the scheduling agent, either directly or by CC-ing it on an email thread. The request might be as simple as "Can you find a time for me and Sarah to meet next week?" or as specific as "Schedule a 30-minute call with the engineering team before Friday." The agent parses the natural language request to identify participants, duration, deadline, and any constraints.

Collecting Availability

The agent emails each participant to ask for their availability. It can check the host's calendar via API to pre-filter times, then present participants with options or ask open-ended questions about their schedule. As responses come in via webhook, the agent extracts time slots from natural language replies and cross-references them against all participants.

Proposing and Confirming Times

Once the agent finds overlapping availability, it proposes the best time to all participants and waits for confirmations. If someone cannot make the proposed time, the agent automatically recalculates and proposes an alternative. When everyone confirms, the agent sends a final confirmation email with the meeting details.

Handling Changes

When a participant needs to reschedule or cancel, they simply reply to the thread. The agent detects the intent, finds new options, and coordinates with all other participants -- all within the same email conversation.

Building a Scheduling Agent with AgentSend

Here is a webhook handler that demonstrates the core scheduling agent logic -- receiving availability, finding overlaps, and sending confirmations:

import requests
from flask import Flask, request, jsonify
from datetime import datetime

app = Flask(__name__)
API_KEY = "YOUR_AGENTSEND_API_KEY"
INBOX_ID = "inbox_scheduler_01"
AGENTSEND_URL = "https://agentsend.io/messages"

# Active scheduling sessions
sessions = {}

@app.route('/webhook/scheduler', methods=['POST'])
def handle_email():
    data = request.json
    sender = data['from']
    body = data['text']
    thread_id = data['threadId']

    # Parse the email for scheduling intent
    intent = parse_scheduling_intent(body)

    if intent['type'] == 'new_request':
        # Start a new scheduling session
        session = create_session(intent['participants'],
                                intent['duration'])
        sessions[thread_id] = session
        # Ask each participant for availability
        for participant in session['participants']:
            send_email(participant,
                f"Finding a time for a {session['duration']}min meeting",
                f"Hi, {sender} would like to schedule a meeting. "
                + "When are you available this week?")

    elif intent['type'] == 'availability':
        # Record this participant's available slots
        session = sessions.get(thread_id)
        if session:
            session['slots'][sender] = intent['time_slots']
            # Check if all participants have responded
            if all_responded(session):
                best_time = find_overlap(session['slots'])
                if best_time:
                    confirm_meeting(session, best_time)
                else:
                    request_more_options(session)

    return jsonify({'status': 'processed'})

def send_email(to, subject, text):
    requests.post(AGENTSEND_URL, json={
        'inboxId': INBOX_ID,
        'to': to,
        'subject': subject,
        'text': text
    }, headers={
        'Authorization': f'Bearer {API_KEY}',
        'Content-Type': 'application/json'
    })

This handler processes three types of incoming emails: new scheduling requests, availability responses, and changes. The parse_scheduling_intent function uses AI to understand the natural language content, while the scheduling logic finds optimal meeting times based on collected availability.

Why Email for Scheduling Agents

Email-based scheduling has distinct advantages over calendar link tools and chatbot-based approaches:

• Zero friction for participants -- no need to create accounts, install apps, or visit external websites. Participants just reply to an email.
• Works across organizations -- email is universal. Your scheduling agent can coordinate meetings between people at different companies with different calendar systems.
• Natural language input -- participants describe their availability in their own words. The AI agent understands "I am slammed Monday but free after lunch on Tuesday" just as well as "Available 2-5pm Tuesday."
• Built-in audit trail -- the email thread serves as a complete record of who was invited, what times were discussed, and what was confirmed.
• Handles edge cases gracefully -- rescheduling, cancellations, and adding new participants are natural email interactions, not awkward UI flows.

What AgentSend Provides for Scheduling Agents

• Dedicated scheduler inbox -- your scheduling agent gets its own email address like scheduler@yourcompany.com, making it easy for anyone to request a meeting.
• Real-time webhooks -- availability responses are delivered to your agent instantly, so it can process and respond without delay.
• Thread management -- each scheduling conversation stays in a single thread, keeping all participants aligned on the same context.
• Multi-participant support -- the agent can manage conversations with multiple participants simultaneously, tracking each person's responses independently.
• Free tier -- coordinate up to 10 email exchanges per day at no cost while you build and test your scheduling agent.
