What Overloop Does

Everything your agent needs
to run outbound that converts.

01

Finds your ideal prospects

Searches a database of 450M+ verified contacts. Define your ICP once (industry, role, company size, location) and let your agent build targeted lists automatically. Exports as JSON for any pipeline.

02

Writes hyper-personalized emails

Analyzes each prospect's website and social profiles. Writes cold emails from scratch in your voice. No templates, no variables. Each message is unique, personalized on both sides: their context, your tone.

03

Runs multi-channel campaigns

Orchestrates sequences across email and LinkedIn with optimized timing, follow-ups, and connection requests. Built on 10 years of real outbound data from 100,000+ campaigns.

04

Tracks and optimizes everything

Opens, clicks, replies, bounces. All tracked in real time. Your agent gets structured performance data to refine targeting, messaging, and timing with every iteration.

Skills

Everything outbound. Nothing else.

Overloop does one thing and does it well. Every skill is available through the CLI, API, and MCP server.

Prospect Sourcing

Create automated sourcings that find leads matching your ICP from 450M+ contacts. Filter by keywords, location, company size, and more.

overloop sourcings:create --name "SaaS CTOs" --search-criteria '{"keywords":"CTO"}'

Campaign Steps

Build multi-channel sequences with email and LinkedIn steps. Configure subject, content, delays, and connection requests.

overloop steps:create --campaign 5 --type email --config '{"subject":"Hi"}'

Campaign Management

Create campaigns, add steps, enroll prospects, and activate. Full lifecycle management from draft to live.

overloop campaigns:create --name "Q1 SaaS CTOs" --timezone "Etc/UTC"

Enrollment

Enroll prospects into campaigns individually or in bulk. Re-enroll when needed. Your agent manages the full pipeline.

overloop enrollments:create --campaign 5 --prospect 42

Prospect Management

Create, search, filter, and update prospects. Manage organizations, lists, custom fields, and exclusion lists.

overloop prospects:list --search "VP Sales" --per-page 50

Conversations

Track replies and manage conversations. Assign owners, archive threads. All output is JSON for agent pipelines.

overloop conversations:list | jq '.data[] | .name'
Agents First

CLI. MCP Server. API.
The web interface is optional.

Overloop's primary interface is not a web app. It's a CLI, an MCP server, and a REST API designed to be consumed by AI agents.

Overloop CLI

$ npm install -g overloop-cli

Full command-line interface to the Overloop platform. Search prospects, compose emails, launch campaigns, and track performance, all from the terminal or any AI agent.

$ overloop campaigns:create --name "Fintech VPs"
{"data":{"id":12,"name":"Fintech VPs","status":"draft"}}

$ overloop steps:create --campaign 12 --type email \
  --config '{"subject":"Hi {{first_name}}"}'

$ overloop enrollments:create --campaign 12 --prospect 42

$ overloop campaigns:update 12 --status on
{"data":{"id":12,"status":"on"}}

Overloop MCP Server

$ npm install overloop-mcp

MCP server that gives Claude, Cursor, and any MCP-compatible agent native access to prospects, campaigns, sourcings, enrollments, conversations, and more.

How It Works

Set it up once.
Let your agent close deals.

Three steps. Ten minutes. Then Overloop runs outbound for you, whether you trigger it or your AI agent does.

01

Install and connect

Install the CLI or add the MCP server to your AI agent. Get your API key from the dashboard. Connect your email accounts and LinkedIn profile.

$ npm install -g overloop-cli
02

Define your ICP

Tell Overloop who you're selling to: role, industry, company size, location. It searches 450M+ contacts and builds your prospect list automatically.

$ overloop sourcings:create --name "SaaS CTOs" --search-criteria '...'
03

Launch and iterate

Your agent creates personalized campaigns, sends them out, and uses performance data to refine the approach. You focus on closing the deals that come in.

$ overloop campaigns:update 12 --status on
