Instantly
Automated email outreach with a B2B lead database, deliverability tools and an AI-powered CRM.
Updated Sep 29, 2026
Overview
Instantly runs cold email outreach: it connects and warms up sending
accounts, sends campaigns with sequences and subsequences, finds leads in its
SuperSearch B2B lead database, verifies email addresses, and keeps replies in
its Unibox inbox and CRM. API v2 takes a workspace API key as a Bearer token;
each key carries scopes, every path starts with /api/v2, and the workspace
shares a limit of 100 requests per second and 6,000 per minute. The
instantly CLI reads the same key from INSTANTLY_API_KEY.
Instantly also hosts an MCP server at https://mcp.instantly.ai/mcp with a
tool for every API v2 endpoint, named like list_campaigns or create_lead.
It authenticates with the API key in the Authorization header, and
instantly mcp runs a local MCP server from the CLI.
