## LinkupAPI

LinkupAPI positions itself as "the outreach API for AI agents and software." Rather than a standalone tool for sales reps, it targets builders: AI agent teams, sales platforms, ATS and CRM vendors that want to embed prospecting and multichannel outreach into their own products without building the underlying plumbing. The service reports over 50 endpoints, sub-three-second average response times and 99.9% uptime, and it exposes the whole loop - Find, Spot intent, Reach, Reply - through the same API key and request format.

The coverage spans four channels: LinkedIn (messages, InMails, invitations, Sales Navigator activity), email (Gmail, Outlook or any SMTP mailbox), WhatsApp (text, files and voice notes) and iMessage (dedicated numbers with tapbacks and read receipts). On the data side it offers a Prospect Data API for people search, full profiles, company data, job postings and funding rounds, plus a Mail API for email verification, discovery and enrichment. An MCP server lets Claude, ChatGPT, Cursor or any MCP client drive outreach directly.

Integration options include n8n, Make and Zapier, and LinkupAPI highlights security and compliance as first-class concerns, advertising a zero-storage architecture alongside GDPR and CCPA alignment. A free trial is available, and the product is aimed at teams that already have a user base or agent to plug outreach into.

**Pricing & Plans:** LinkupAPI is a paid, credit-based API product. The site advertises a free trial with API keys and usage metered in credits (for example, a send action consuming credits). Exact plan tiers and per-credit pricing are not published on the homepage, so check the pricing page or sales for current numbers.

- **One API for four channels:** Send on LinkedIn, email, WhatsApp and iMessage with the same request format, and receive all replies on a single webhook.
- **Prospect and company data:** Search people, pull full profiles, company details, job postings and funding rounds as JSON for your product or agent.
- **Mail API:** Verify, find and enrich professional email addresses at scale, with real-time deliverability checks.
- **MCP server:** Run searches, messages and reply reads from Claude, ChatGPT, Cursor or any MCP-compatible client.
- **Automation and compliance:** Native n8n, Make and Zapier integrations plus a zero-storage architecture with GDPR and CCPA alignment.

**Strengths:** Single API covering search, messaging, data enrichment and replies reduces vendor sprawl; Strong channel breadth, including iMessage and WhatsApp alongside LinkedIn and email; MCP server enables direct use from mainstream LLM clients; Published performance and compliance posture (99.9% uptime, zero-storage, GDPR/CCPA)

**Limitations:** Credit-based usage makes cost forecasting harder without careful monitoring; Homepage does not publish detailed price tiers, so evaluation requires contacting sales or the pricing page; Multichannel outreach at scale carries platform-policy and deliverability risk that users must manage

## Salesforge

Salesforge's core pitch is volume without seat taxes. Instead of charging per mailbox or per sending seat, it lets you connect as many mailboxes and LinkedIn senders as you need, then orchestrates outreach through conditional multichannel sequences. That makes it a natural fit for agencies and growth teams juggling many domains, clients or territories at once.

The AI layer sits on top of that infrastructure. Agent Frank acts as an autonomous SDR that researches prospects, writes personalized copy and executes campaigns, while Primebox consolidates replies from email and LinkedIn into one place for fast, organized follow-up. Supporting products in the Forge stack handle the plumbing: dedicated inbox provisioning, private sending infrastructure and a deliverability center that includes warm-up and placement testing.

Lead sourcing rounds out the workflow through a search engine for B2B contacts, and the platform exposes an API, MCP integration and CLI so outreach can be automated from outside the app. Salesforge also publishes a generous set of free cold outreach utilities, from subject line generators to blacklist checkers, which double as a low-friction entry point for new users.

**Pricing & Plans:** Salesforge uses a subscription model with a free trial; unlimited mailboxes and LinkedIn senders are included rather than priced per seat. Email infrastructure products (dedicated inboxes, private servers, warm-up) are sold alongside the main platform, and whitelabel plans exist for resellers. Current prices are listed on the official pricing page.

- **Multichannel sequences:** Email and LinkedIn sequences run together with conditional branching, so prospects get consistent follow-ups across every touchpoint
- **Unlimited mailboxes and LinkedIn senders:** Add any number of mailboxes and LinkedIn senders without seat-based limits, letting your whole team send from one workspace
- **AI SDR: Agent Frank:** The built-in AI SDR researches prospects, drafts personalized copy and executes campaigns autonomously
- **Primebox reply management:** Replies from email and LinkedIn land in a single inbox with AI analysis, so nothing slips through
- **Lead data and deliverability tools:** A large verified B2B contact database plus warm-up and deliverability tooling to protect inbox placement

**Strengths:** Unlimited mailboxes and LinkedIn senders remove the usual per-seat sending limits; AI SDR and AI copywriting cut the manual effort in research, drafting and follow-up; Reply management plus warm-up and deliverability tooling are bundled in one ecosystem; Strong automation surface with API, MCP and CLI access

**Limitations:** Unlimited-sending positioning means deliverability discipline is on you; users without warmed infrastructure can still land in spam; Feature breadth across many sub-products (Mailforge, Infraforge, Warmforge, Primeforge, Leadsforge) can feel complex to learn; Some advanced capabilities such as whitelabel reselling require higher-tier plans
