Will my users' accounts get banned?

Account safety is the core of LinkupAPI. Every connected account gets its own dedicated IP in its country, sessions are bound to a single device signature, and no software is installed on users' machines. The platform monitors account activity and health, alerting you immediately if an account gets flagged so you can slow down before it causes an issue.

How does pricing work and is there a per-account fee?

Yes, pricing is per connected account with unlimited usage. Plans start at $55/month for 10 accounts, then scale from $5.50 down to $4.50 per account. At 640+ accounts, the Unlimited plan covers every account for $3,000/month flat. Dedicated iMessage lines are available as an add-on at $199 per line per month.

Which channels are supported?

LinkupAPI supports LinkedIn (messages, invitations, Sales Navigator InMails, posts and engagement), email (Gmail and Outlook mailboxes with email finder and verification), WhatsApp, and iMessage (dedicated US or UK numbers). The same API call works for all channels, and replies come back through the same webhooks.

Does it work with Claude, ChatGPT or my own agent?

Yes. LinkupAPI provides an MCP server that can be plugged into Claude, ChatGPT, Gemini or any MCP client with one click. It also offers a REST API for custom agents. No-code users can integrate through Make, n8n or Zapier.

How do I get replies and is it GDPR compliant?

Every reply, accepted invitation and bounce is pushed to your webhook in real time with retries and a delivery log, or you can poll the events endpoint. LinkupAPI is GDPR and CCPA compliant—it never stores user credentials, conversation data is processed only for delivery and not retained, and you can cancel anytime with no fees. All paid plans include email support within 24 hours.

An API for AI agents and software to send messages on LinkedIn, email, WhatsApp and iMessage, with dedicated account safety infrastructure and real-time reply

Overview

A look at linkupapi.com

LinkupAPI is an outreach API that enables AI agents and software to send messages across LinkedIn, email, WhatsApp and iMessage through a single unified API. Users can search prospects using LinkedIn profiles, find and verify work emails, send messages at scale, and receive every reply in real time through webhooks.

The platform prioritizes account safety by running entirely server-side with no browser extensions. Each connected account gets its own dedicated IP address matched to its country, encrypted sessions bound to a single device signature, and active monitoring rather than arbitrary daily limits. The API supports Claude, ChatGPT and Gemini through an MCP server, or integrates with REST endpoints for custom agents.

Pricing is based on connected accounts—starting at $55/month for 10 accounts, scaling down to $4.50 per account, with an unlimited plan at $3,000/month flat after 640 accounts. Dedicated iMessage lines are available as an add-on. All plans include unlimited usage with no per-call credits or fees.
