Perplexity

Run Loops transactional tests inside Claude Desktop

The `send_transactional_email` tool lets you trigger transactional templates right from your chat prompt in Claude Desktop. This desktop client fires the exact API payload to your Loops account instantly. Instead of opening a browser tab to check your history, you tell Claude Desktop to run `list_transactional_emails` to fetch your recent Loops logs. This MCP Server connection keeps your Loops email debugging inside your Claude Desktop chat interface.

Manage your Loops subscriber audience using the MCP Server

The `create_contact` tool inserts new subscribers into your Loops database directly from the Claude Desktop sidebar. You only need to type the email address into the Claude Desktop chat window to add them to your Loops mailing lists. When a customer requests an update, Claude Desktop uses `update_contact` to modify their properties in your Loops dashboard. Your desktop agent can also run `delete_contact` to purge test users from Loops without leaving your conversation.

Verify Loops suppressions inside Claude Desktop

The `get_contact_suppression` tool checks if a specific email address is suppressed from receiving your Loops campaigns inside Claude Desktop. Claude Desktop queries this suppression status directly to help you diagnose Loops delivery issues. You can also command Claude Desktop to run `list_mailing_lists` to see your active Loops segments. This MCP Server query ensures you target the right Loops audience before sending from Claude Desktop.
