**What is SalesMix?** 

## More LinkedIn conversations, without more busywork.

SalesMix runs your LinkedIn outreach for you. Connect as many LinkedIn accounts as you have, build a campaign once, and SalesMix sends the invites, follow-ups and InMails, then puts every reply in one inbox.

[See how it works](https://salesmix.com/product) [See pricing](https://salesmix.com/pricing)

**In short** 

SalesMix is a LinkedIn outreach tool with unlimited connected accounts for one flat price ($1,000/mo founding, $1,999/mo standard). Everything in it, from campaigns to leads to replies, is also an API, so your tools and AI agents can run outreach too.

-   Send connection requests, messages, InMails and email follow-ups automatically
-   Every reply from every account in one inbox
-   7-day free trial, cancel anytime

**Built API-first** 

## If you can click it, your code can do it.

The app and the API are the same thing. Automate any part of your LinkedIn outreach, or let an AI agent do it for you.

**The product** 

## Everything you need to book meetings on LinkedIn.

From the first profile visit to the reply that says “let’s talk”, in one tool.

**Campaigns** 

### Launch your first campaign in minutes.

Pick who you want to reach and SalesMix sets up the right steps: new connections, people you already know, open profiles, or the full LinkedIn + email flow.

-   Four ready-made campaign types
-   LinkedIn and email in one flow
-   No blank page, no setup call needed

**Builder** 

### Follow up automatically, based on what each lead does.

Accepted your invite? Send a message. Didn’t accept? Try an InMail or an email. Replied? Stop. Every lead gets the right next step without you lifting a finger.

-   10 steps: invites, messages, InMails, emails, visits, likes and more
-   Personal messages with `{{first_name}}`, `{{company}}` or any column
-   AI drafts that you approve before they send

**Unlimited accounts** 

### Add every account. Send more, safely.

More accounts means more conversations without pushing any single profile too hard. SalesMix shares each campaign across your accounts and keeps every one inside its own limits.

We only step in for abuse, like reselling access, and we always contact you first. Each account still follows safe LinkedIn daily limits. [Read the fair use policy →](https://salesmix.com/fair-use) on one flat price
-   Daily limits and working hours per account
-   New accounts warm up gradually

**Inbox** 

### Never miss a reply again.

Replies from every account land in one inbox, sorted by intent. Answer in seconds without logging in and out of LinkedIn.

**Approvals** 

### Let AI write. You approve.

AI drafts the messages, you check them before they go out. Approve a whole batch in one click.

**Analytics** 

### See exactly what books meetings.

One view from invite to interested reply, for every campaign and account. Find the step that loses people and fix it.

-   Acceptance, reply and interested rates
-   Compare campaigns and accounts side by side
-   Pull the numbers into any report with the API

**For builders** 

## Plug LinkedIn into your stack and your AI agents.

Stop exporting CSVs. Send leads straight from Clay, react to replies in your own code, or let an AI agent run outreach while a human approves.

### A simple REST API

Clear endpoints, safe retries, and SDKs for Node and Python.

### Instant webhooks

Know the second someone accepts, replies or shows interest.

### An MCP server for AI agents

Claude, Cursor or your own agent can run campaigns, with your approval.

**Before you decide** 

## Questions and honest answers.

Including the ones people ask right before they decide not to try it.

### ### Is it really unlimited LinkedIn accounts?

Yes. Connect every LinkedIn account you, your team and your clients use, for one flat price. There’s no per-account or per-seat fee. Our [fair use policy](https://salesmix.com/fair-use) only stops abuse, like reselling access. Normal outreach is never capped.

### ### What’s the catch with $1,000 a month?

It’s a founding price for our first 10 customers, in exchange for early feedback. You keep $1,000/mo for as long as you stay a customer. Once the spots are gone, Unlimited is $1,999/mo.

### ### Will automating LinkedIn get my accounts restricted?

Any LinkedIn automation carries some risk, and nobody can honestly promise zero. SalesMix keeps it low: every account stays inside daily limits you set, activity is spread across working hours, new accounts warm up slowly, and volume is shared across accounts instead of pushing one hard. See [how SalesMix keeps accounts safe](https://salesmix.com/linkedin-account-safety).

### ### Is LinkedIn automation allowed by LinkedIn?

LinkedIn’s User Agreement restricts third-party automation, so review it and decide what’s right for your team. SalesMix is not affiliated with LinkedIn. We keep a human in control with [approvals](https://salesmix.com/product#approvals), careful pacing and per-account limits.

### ### I’m not a developer. Is this for me?

Yes. The [campaign builder](https://salesmix.com/product#builder), inbox and approvals work without code. The API is there when you want Clay, your CRM or an AI agent to do more of the work for you.

### ### We already use HeyReach or Expandi. Why switch?

Two reasons: price and control. Unlimited accounts cost $1,000/mo here versus $2,999/mo for HeyReach Unlimited, and everything in SalesMix runs from an API and an [MCP server](https://salesmix.com/mcp). See [SalesMix vs HeyReach](https://salesmix.com/compare/heyreach-alternative) and [SalesMix vs Expandi](https://salesmix.com/compare/expandi-alternative).

### ### Won’t automated messages sound robotic?

Only if they’re written that way. You write the messages, personalize them with any column you import, and can let AI draft them while a person approves each one before it sends.

### ### How fast can we be up and running?

Most teams connect an account, import a list and launch a first campaign in under an hour. Founding customers also get an onboarding call with the founders.

### ### Do I need Sales Navigator or LinkedIn Premium?

No. SalesMix works with free, Premium and Sales Navigator accounts. Paid LinkedIn plans add InMail credits, which SalesMix uses when they’re available.

### ### What if it’s not for us?

Start with a 7-day free trial on 1 LinkedIn account. A card is required, but cancel before day 8 and you pay nothing. Paid plans are monthly and you can cancel any time. Your campaigns, leads and conversations can be exported through the app or the [API](https://salesmix.com/api).
