# Emailvalidation MCP

Vendor: Emailvalidation  
Category: other  
Auth: API_KEY  
Composio slug: `emailvalidation`

Validate individual email addresses for deliverability and quality signals, and inspect account quota usage through emailvalidation.io's complete REST API surface.

## Verdict

This MCP validates email addresses in real time, checking deliverability, format, domain health, and whether an address is disposable or role-based. Teams use it to clean contact lists, verify signups before onboarding, or audit CRM data without leaving Switchy. Each validation costs one credit from your Emailvalidation.io account. The MCP exposes two tools: one checks your remaining quota, the other validates a single address and returns a detailed report. Marketing ops and customer success teams get the most value when they need to verify dozens of addresses during planning sessions or data cleanup sprints.

## Tools

- **Get Account Quota Status** — Return the connected emailvalidation.io account ID and current monthly and grace credit totals, usage, and remaining balances. This status check does not consume validation credits or count against the API rate limit.
- **Validate Email Address** — Validate one email address and return deliverability, format, mailbox, domain, role-address, disposable-address, and quality signals. Each successful validation costs one account credit. Catch-all detection is optional, disabled by default,

## Setup

1. Create or open a Switchy Project.
2. Open Integrations and connect Emailvalidation.
3. Authorise through api_key.
4. Teammates can now @-mention Emailvalidation tools in chat.
