## Description

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with Verifiedemail MCP or direct API to verify email addresses, clean bulk lists, check deliverability, and reduce bounce rates through natural language.

## Summary

Verifiedemail is a service for real-time email verification and bulk cleaning. It helps you maintain accurate, high-quality email lists for better deliverability.

## Categories

- marketing & social media

## Toolkit Details

- Tools: 9

## Images

- Logo: https://logos.composio.dev/api/verifiedemail

## Authentication

- **Api Key**
  - Type: `api_key`
  - Description: Api Key authentication for Verifiedemail.
  - Setup:
    - Configure Api Key credentials for Verifiedemail.
    - Use the credentials when creating an auth config in Composio.

## Suggested Prompts

- Verify if this email address is valid
- Check remaining email verification credits
- Get status of my recent file upload
- Retrieve all shared credential IDs for my account

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `VERIFIEDEMAIL_CHECK_CREDITS` | Check Credits | Tool to retrieve the remaining verification credits. Call before VERIFIEDEMAIL_VERIFY_EMAIL operations—especially in bulk or repeated workflows—as VERIFIEDEMAIL_VERIFY_EMAIL fails immediately when credits are exhausted. Use after confirming account authentication to ensure sufficient credits before proceeding. |
| `VERIFIEDEMAIL_CHECK_FILE_STATUS` | Check File Status | Tool to check the status of a previously uploaded file. Use after uploading a file when polling for verification progress. |
| `VERIFIEDEMAIL_GET1_CLICK_USER_DATA` | Get 1-Click User Data | Tool to retrieve data for a user who has completed a 1-Click Signup flow. Use after you have the identityUuid to fetch the verified user's full profile. |
| `VERIFIEDEMAIL_GET_ENTITLEMENTS` | Get Entitlements | Tool to retrieve information about available credits across different entitlement types. Use when you need to check credit availability before performing operations that consume credits. |
| `VERIFIEDEMAIL_GET_SHARED_CREDENTIALS` | Get Shared Credentials | Tool to retrieve a list of shared credential IDs. Use when you need to fetch all credentials shared to your account after authentication. |
| `VERIFIEDEMAIL_LIST_DOWNLOADS` | List Downloads | Tool to get a list of previously created download requests. Use when you need to retrieve information about download requests that have been created for verification results. |
| `VERIFIEDEMAIL_LIST_LISTS` | List Lists | Tool to get all email lists in your account. Use when you need to retrieve and view all verification lists with optional pagination and sorting. |
| `VERIFIEDEMAIL_POST1_CLICK_CREDENTIALS_UPDATE` | Update 1-Click Credentials | Tool to update 1-Click credentials. Use after obtaining a 1-Click session uuid when you need to update user-provided credential values in a non-hosted or trusted flow. |
| `VERIFIEDEMAIL_VERIFY_EMAIL` | Verify Email | Tool to verify the deliverability and validity of an email address. Use when you need to confirm if an email can receive mail by checking server existence, mailbox status, and more. For bulk use, call VERIFIEDEMAIL_CHECK_CREDITS first — this tool fails if verification credits are exhausted. |

## Installation and MCP Setup

### Path 1: SDK Installation

#### Path 1, Step 1: Install Composio

Install the Composio SDK, the OpenAI provider, and the OpenAI SDK
```python
pip install composio composio_openai openai
```

```typescript
npm install @composio/core @composio/openai openai
```

#### Path 1, Step 2: Create a Composio session

Initialize Composio with the OpenAI Responses provider and create a session scoped to Verifiedemail
```python
import json
from openai import OpenAI
from composio import Composio
from composio_openai import OpenAIResponsesProvider

composio = Composio(provider=OpenAIResponsesProvider())
client = OpenAI()

session = composio.create(user_id="your-user-id", toolkits=["verifiedemail"])
tools = session.tools()
```

```typescript
import OpenAI from "openai";
import { Composio } from "@composio/core";
import { OpenAIResponsesProvider } from "@composio/openai";

const composio = new Composio({ provider: new OpenAIResponsesProvider() });
const client = new OpenAI();

const session = await composio.create("your-user-id", { toolkits: ["verifiedemail"] });
const tools = await session.tools();
```

#### Path 1, Step 3: Run Verifiedemail tools with your agent

Send a request, execute the Verifiedemail tool calls through the session, and print the final answer
```python
response = client.responses.create(
    model="gpt-5.6-sol",
    tools=tools,
    input=[{"role": "user", "content": "Verify deliverability of this email address: alice@example.com"}],
)

while True:
    tool_calls = [o for o in response.output if o.type == "function_call"]
    if not tool_calls:
        break
    results = composio.provider.handle_tool_calls(response=response, session=session)
    response = client.responses.create(
        model="gpt-5.6-sol",
        tools=tools,
        previous_response_id=response.id,
        input=[
            {"type": "function_call_output", "call_id": call.call_id, "output": json.dumps(results[i])}
            for i, call in enumerate(tool_calls)
        ],
    )

print(response.output_text)
```

```typescript
let response = await client.responses.create({
  model: "gpt-5.6-sol",
  tools,
  input: [{ role: "user", content: "Verify deliverability of this email address: alice@example.com" }],
});

while (response.output.some((o) => o.type === "function_call")) {
  const outputs = await composio.provider.handleToolCalls(session, response.output);
  response = await client.responses.create({
    model: "gpt-5.6-sol",
    tools,
    previous_response_id: response.id,
    input: outputs,
  });
}

console.log(response.output_text);
```

### Path 2: MCP Server Setup

#### Path 2, Step 1: Install Composio

Install the Composio SDK and your agent framework
```python
pip install composio claude-agent-sdk
```

```typescript
npm install @composio/core ai @ai-sdk/mcp @ai-sdk/openai
```

#### Path 2, Step 2: Create a session with MCP enabled

Create a session scoped to Verifiedemail and read its MCP URL and headers
```python
from composio import Composio

composio = Composio()
session = composio.create(user_id="your-user-id", toolkits=["verifiedemail"], mcp=True)
```

```typescript
import { Composio } from "@composio/core";

const composio = new Composio();
const { mcp } = await composio.create("your-user-id", {
  toolkits: ["verifiedemail"],
  mcp: true,
});
```

#### Path 2, Step 3: Connect your agent to the MCP server

Pass the session's MCP URL and headers to your agent and run a Verifiedemail request
```python
import asyncio
from claude_agent_sdk import ClaudeSDKClient, ClaudeAgentOptions, AssistantMessage, TextBlock

options = ClaudeAgentOptions(
    mcp_servers={
        "composio": {
            "type": "http",
            "url": session.mcp.url,
            "headers": session.mcp.headers,
        }
    },
    system_prompt="You are a helpful assistant with access to Verifiedemail tools.",
    tools=[],
    allowed_tools=["mcp__composio__*"],
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query("Verify deliverability of this email address: alice@example.com")
        async for message in client.receive_response():
            if isinstance(message, AssistantMessage):
                for block in message.content:
                    if isinstance(block, TextBlock):
                        print(block.text)

asyncio.run(main())
```

```typescript
import { createMCPClient } from "@ai-sdk/mcp";
import { openai } from "@ai-sdk/openai";
import { generateText, stepCountIs } from "ai";

const client = await createMCPClient({
  transport: { type: "http", url: mcp.url, headers: mcp.headers },
});

const { text } = await generateText({
  model: openai("gpt-5.6-sol"),
  tools: await client.tools(),
  prompt: "Verify deliverability of this email address: alice@example.com",
  stopWhen: stepCountIs(10),
});

console.log(text);
await client.close();
```
