Mailcheck

Mailcheck is an email verification service that checks email validity in real time. It helps businesses reduce bounce rates and improve email deliverability.

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with Mailcheck MCP or direct API to verify email addresses, check deliverability, validate lists, and reduce bounces through natural language.

This toolkit is available to Gleap Custom Agents through Composio. Agents can combine Gleap customer data with Mailcheck actions so they can read context, write updates, and trigger cross-app workflows from one place. Supported authentication: Api Key.

How Gleap uses this through Composio

  • Connect the external app through Composio-backed authentication.
  • Give a custom agent scoped access to the actions it needs.
  • Let the agent use Gleap context together with the external app to complete the workflow.
