How to connect Emailable to Claude

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Emailable account to Claude via Composio Connect, enabling it to check if this email address is valid, verify a list of emails before newsletter send, get your Emailable account credit balance, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

The Emailable MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Emailable account. It provides structured and secure access to your email verification services, so your agent can perform actions like real-time email validation, bulk batch checks, account monitoring, and verification status tracking on your behalf.

• Instant email address verification: Ask your agent to check if a single email address is valid, risky, or deliverable before you send that important message.
• Bulk batch email validation: Have the agent verify thousands of email addresses at once for newsletters, campaigns, or CRM imports, ensuring high deliverability rates.
• Batch job status monitoring: Let your agent track the progress and results of ongoing or completed batch verification jobs for timely follow-up actions.
• Account status and credit checks: Retrieve your Emailable account details, including owner info and available credits, to make sure you never run out of verification capacity.
• Seamless OAuth onboarding: Initiate the OAuth flow to securely grant your agent access to Emailable whenever needed, all without manual credential handling.
