Mails.so

Mails is an API service that provides powerful email validation capabilities to help maintain a clean and effective email list.

This is a first-class FlyMyAI MCP. Agents discover it automatically via tool search and call the actions below on demand - you never wire it up by hand. See the Composio catalog for how discovery works.

Connect​

Mails.so authenticates with an API key. Generate the credential in your Mails.so account, then paste it into FlyMyAI the first time an agent uses a Mails.so action.
