iGPT Email Search#

Search a user's email by meaning, not just keywords. Hybrid semantic + keyword retrieval across their entire inbox history.

What This Skill Does#

This skill queries iGPT's recall/search endpoint to find relevant emails and threads from a user's connected inbox. The search engine:

• Combines semantic vector search (understands meaning) with keyword matching (catches exact terms)
• Searches across the user's full indexed email history (not limited to 90 days like some providers)
• Supports date range filtering for time-bounded queries
• Returns ranked results with relevance scoring
• Includes attachment references when present

This is retrieval only. It finds and returns email content. It does not reason over it, summarize it, or extract structured data. For that, use igpt-email-ask — the companion skill that runs iGPT's Context Engine for analysis, summarization, and structured extraction.

When to Use This Skill#

• Find emails about a specific topic, project, or person
• Locate threads within a date range
• Retrieve raw email content for further processing
• Feed email context into another tool or agent step
• Check what was discussed about a topic before taking action
• Pull recent correspondence with a specific contact or company

When to Use igpt-email-ask Instead#

If you need summarized or synthesized answers, structured data extraction (tasks, decisions, contacts), sentiment analysis, reasoning across multiple threads, or questions that require understanding rather than finding — use igpt-email-ask, not search.

Rule of thumb: if the prompt is a question, use ask. If the prompt is a lookup, use search.

Prerequisites#

1. An iGPT API key (get one at https://igpt.ai/hub/apikeys/)
2. A connected email datasource — the user must have completed OAuth authorization via connectors/authorize before search will return results
3. Python >= 3.8 with the igptai package installed

Setup#

bash

pip install igptai

Set your API key as an environment variable:

bash

export IGPT_API_KEY="your-api-key-here"

Usage#

Basic: Search by topic#

python

from igptai import IGPT
import os

igpt = IGPT(api_key=os.environ["IGPT_API_KEY"], user="user_123")

results = igpt.recall.search(query="board meeting notes")
print(results)

Returns a ranked list of relevant emails and threads matching the query, ordered by relevance.

Search with date range#

Narrow results to a specific time window:

python

results = igpt.recall.search(
    query="budget allocation",
    date_from="2026-01-01",
    date_to="2026-01-31"
)
print(results)

Limit number of results#

python

results = igpt.recall.search(
    query="partnership proposals",
    max_results=10
)
print(results)

Search for a specific person's emails#

The semantic engine understands participant context:

python

results = igpt.recall.search(
    query="emails from Sarah about the product launch",
    date_from="2026-01-01"
)
print(results)

Combine with ask for a two-step workflow#

A common pattern: search first to see what's there, then ask for analysis:

python

# Step 1: Find relevant threads
results = igpt.recall.search(
    query="Acme Corp contract negotiation",
    max_results=20
)
print(f"Found {len(results)} relevant threads")

# Step 2: Ask for structured analysis
analysis = igpt.recall.ask(
    input="Summarize the current status of the Acme Corp contract negotiation. What are the open issues and who owns them?",
    output_format="json"
)
print(analysis)

Parameters#

ParameterTypeRequiredDescriptionquerystringYesSearch query. Supports natural language (semantic) and exact terms (keyword).userstringYes (or set in constructor)Unique user identifier scoping the query to their connected data.date_fromstringNoStart date filter in YYYY-MM-DD format.date_tostringNoEnd date filter in YYYY-MM-DD format.max_resultsintegerNoMaximum number of results to return.

Error Handling#

The SDK uses a no-throw pattern. Errors are returned as values, not exceptions:

python

results = igpt.recall.search(query="Q4 planning")

if isinstance(results, dict) and results.get("error"):
    error = results["error"]
    if error == "auth":
        print("Check your API key")
    elif error == "params":
        print("Check your request parameters")
    elif error == "network_error":
        print("Network issue, retry")
else:
    for result in results:
        print(result)

External Endpoints#

This skill communicates exclusively with:

• https://api.igpt.ai/v1/recall/search — the search endpoint
• https://api.igpt.ai/v1/connectors/authorize — only during initial datasource connection setup

No other external endpoints are contacted. No data is sent to any third-party service. The igptai PyPI package source is available at https://github.com/igptai/igptai-python.

Security & Privacy#

• API-key scoped: All requests authenticate via IGPT_API_KEY sent as a Bearer token over HTTPS. No shell access, no filesystem access, no system commands.
• Per-user isolation: Every query is scoped to a specific user identifier. User A cannot access User B's email data. Isolation is enforced at the index and execution level, not as a filter layer.
• OAuth read-only: The email datasource connection uses OAuth with read-only scopes. The skill does not send, modify, or delete emails.
• No data retention: Prompts are discarded after execution. Memory is reconstructed on-demand, not stored.
• Transport encryption: All communication occurs over HTTPS. No plaintext endpoints.
• No local persistence: This skill does not write to disk, modify environment files, or create persistent configuration outside of the standard IGPT_API_KEY environment variable.

How It Differs from Basic Email Search#

Basic email/Gmail searchiGPT Email SearchKeyword matching onlySemantic + keyword hybridMisses related content using different wordsUnderstands meaning, finds conceptually related emailsLimited to Gmail's search operatorsNatural language queries workProvider-specific (Gmail OR Outlook)Searches across all connected providersOften limited history (Nylas: 90 days)Full email history indexedReturns raw MIME dataReturns clean, structured results

Example Queries#

These all work as natural language:

• "board meeting notes" — finds emails about board meetings even if they don't contain that exact phrase
• "emails about the product launch timeline" — semantic understanding of the topic
• "anything from legal about compliance" — understands department and topic context
• "invoices from Q4 2025" — combines topic with implicit date context
• "conversations where deadlines were mentioned" — conceptual search
