Spaces vs HeyReach
HeyReach is a multi-sender LinkedIn outbound platform: campaigns across many LinkedIn accounts at once, sender rotation, a unified inbox for every reply, email through Instantly and Smartlead, and an MCP server that lets Claude or ChatGPT build and launch those campaigns — priced per sender. Spaces is messaging infrastructure for AI agents: one REST API and one MCP server that let the agent you already use — in Claude, Grok, ChatGPT, Cursor or your own code — read and answer conversations on Instagram, WhatsApp, LinkedIn and Messenger.
In one line: HeyReach scales sequenced LinkedIn outbound; Spaces is how your own agent answers the people who write to you. For sequenced cold outreach, HeyReach is the better fit. Spaces is not built for that. Its own guidance says not to use it for "cold outreach at scale, bulk unsolicited messages, or bought or scraped contact lists", and that "Spaces does not send bulk unsolicited messages or build lists of strangers to contact."

| Spaces | HeyReach | |
|---|---|---|
| What it is | Messaging API + MCP server for AI agents | Multi-sender LinkedIn outbound platform |
| Built for | Developers and businesses whose agent answers and follows up on chat apps | Agencies, sales and growth teams running LinkedIn outbound at scale |
| Channels | Instagram, WhatsApp, LinkedIn and Messenger (inbox). TikTok posts and comments are live — no TikTok DM inbox. Facebook Pages coming soon. | LinkedIn, with email through native Instantly and Smartlead integrations. WhatsApp, Instagram and Messenger are not listed. |
| The number you already use, linked by QR code, and it keeps working on your phone. No Meta approval, no templates and no Meta message fees. | Not listed as a channel. | |
| Cold outreach | Not what it is for: refuses the same cold text sent to many people | The core product: campaigns to imported or enriched lead lists, sender rotation |
| AI | No built-in agent: bring your own. Routines for new messages, keywords, accepted connections and no-reply follow-ups. | HeyReach MCP and a CLI for Claude, ChatGPT, Codex and other clients |
| MCP | https://api.spacesos.com/mcp, every plan including Free; optional approvals or draft-only keys | https://mcp.heyreach.io/mcp, no extra cost. The AI can read conversations, send LinkedIn messages, and create, start, pause and resume campaigns. |
| Who you pay for | Connected accounts; no seats | Senders (LinkedIn accounts); teammates, VAs and clients are free |
| Price | Free: $0, 1 account, 50 actions a day, no card. Pay as you go: $9 per connected account a month, with 1,000 actions a month per account (pooled), then $5 per 1,000 (less at high volume). Reading messages is always free. No seats, no yearly option. | Growth: $79 a sender a month for 1–9 senders, $59 from 10 senders, less billed quarterly or yearly. Agency: $999 a month for 25 senders. 14-day trial with 3 LinkedIn accounts, no card. |
| 5 LinkedIn accounts | $45 a month (5 × $9, 5,000 actions pooled) | $395 a month on Growth billed monthly (5 × $79) |
| 10 LinkedIn accounts | $90 a month (10 × $9, 10,000 actions pooled) | $590 a month on Growth billed monthly (10 × $59) |
Example assumes five, then ten LinkedIn profiles, within Spaces' included actions (each extra 1,000 actions is $5). This is not a like-for-like price. HeyReach's sender price buys an outbound system — campaigns, sender rotation, enrichment credits, a proxy per sender, white-label on Agency — that Spaces does not include and will not run. Spaces' price buys accounts your agent works across four chat apps, mostly answering people who wrote first, and does not include what your AI model costs to run. Prices exclude tax.
Choose HeyReach if
- You run LinkedIn outbound across many sender accounts and want sending rotated between them.
- You want your AI to build and launch LinkedIn campaigns from Claude or ChatGPT.
- You are an agency managing clients' LinkedIn outreach from one login, with white-label options.
- You want LinkedIn campaigns tied to email tools such as Instantly or Smartlead.
Choose Spaces if
- Your agent should answer and follow up with people who already know the business, not run volume outbound.
- You need WhatsApp, Instagram and Messenger alongside LinkedIn, through one API and MCP server.
- You want per-account limits and a warm-up on every account, set for you.
- You want a Free plan, then a low per-account price at small counts.
About how WhatsApp connects
HeyReach does not list WhatsApp, so this only matters if your agent also needs WhatsApp, Instagram or Messenger.
Spaces links the WhatsApp number you already use by QR code, without the Business API. For up to 24 hours after a WhatsApp account connects, reconnects, or is disconnected and connected again, Spaces does not start new chats or outreach. Replies in chats that already exist still go out. Other channels have no reply-only window: the warm-up limits apply from the first day, and replies to people who wrote in go out immediately. That number stays under WhatsApp's own automation rules: Spaces keeps every account inside limits, which lowers the risk without removing it.
