The HeyReach alternative for AI agents that answer, not just send
HeyReach is built to push LinkedIn outbound across many sender accounts at once, and its MCP server lets Claude or ChatGPT build and launch those campaigns. It is very good at that. But it is LinkedIn only, and its job is outreach. If what you are building is an AI agent that answers the people who already write to a business — on LinkedIn and on WhatsApp, Instagram and Messenger — that is a different job. That is what Spaces is for.
Every HeyReach fact below comes from HeyReach's own website and developer docs, checked on 11 November 2026. Where HeyReach is the better choice, we say so.

Two different products, one sentence each
- HeyReach is a LinkedIn outreach platform for agencies, sales and growth teams: unlimited campaigns of connection requests, messages, follow-ups, voice notes and profile views across many LinkedIn sender accounts, a unified inbox, email through Instantly and Smartlead, an API, webhooks, a CLI and an MCP server, priced per sender. (pricing, MCP, llms.txt)
- Spaces is messaging infrastructure for AI agents: one REST API and one MCP server that let the agent you already use — Claude, Grok, ChatGPT, Cursor or your own code — read and reply to conversations on the Instagram, WhatsApp, LinkedIn and Messenger accounts a business already has, inside each platform's limits, priced per connected account. (pricing, llms.txt)
The short version: HeyReach scales LinkedIn outbound. Spaces lets your agent hold the conversations, on LinkedIn and three other chat apps.
Spaces vs HeyReach, head to head
| Spaces | HeyReach | |
|---|---|---|
| What it is | Messaging API + MCP server for AI agents on existing chat accounts | Multi-sender LinkedIn outbound platform |
| Main job | Let your own agent answer, follow up and hand over customer conversations | Run LinkedIn campaigns across many senders and manage every reply in one inbox |
| Inbox / DM channels | Instagram, WhatsApp, LinkedIn and Messenger | LinkedIn. Email through native Instantly and Smartlead integrations. WhatsApp, Instagram and Messenger are not listed |
| Other channels | TikTok for posts and comments (no TikTok DM inbox). Facebook Pages coming soon | LinkedIn voice notes, profile views, follows |
| Cold outreach to new prospects | Not what it is for: Spaces refuses the same cold text sent to many people and does not build lists of strangers to contact | The core product: campaigns to imported or enriched lead lists, "If Connected" conditions, email finder credits |
| MCP server | https://api.spacesos.com/mcp (plus one per channel), every plan including Free | https://mcp.heyreach.io/mcp; sign-in for Claude, ChatGPT and Codex, MCP key for other clients; HeyReach says the MCP costs nothing extra |
| What the AI can do over MCP | Read chats, reply, start a chat where allowed, schedule, run routines; optional approvals or draft-only keys | List and read conversations, send LinkedIn messages, create, start, pause and resume campaigns, manage leads and lists |
| API and webhooks | REST API on every plan; webhooks on Pay as you go | API and webhooks on every plan; CLI; Clay, Make, n8n, Zapier, HubSpot |
| Who you pay for | Connected accounts | Senders (LinkedIn accounts); teammates, VAs and clients are free |
| Free option | Free plan: 1 account, 50 actions a day, no card | 14-day trial with 3 LinkedIn accounts, no card |
| Price: 5 LinkedIn accounts (monthly) | $45/month (5 accounts × $9, 5,000 actions a month pooled) | $395/month on Growth billed monthly (5 × $79); $72 a sender billed quarterly, $64 billed yearly |
| Same, 10 accounts | $90/month (10 × $9, 10,000 actions pooled) | $590/month on Growth ($59 a sender from 10 senders), less quarterly or yearly |
Price assumption: an agency or sales team running five LinkedIn profiles, then ten. On HeyReach those are senders on Growth (up to 50 senders); 25 senders are $999 a month on Agency. On Spaces they are connected accounts on Pay as you go, within the included actions; each extra 1,000 actions is $5. Spaces prices are from spacesos.com/pricing; HeyReach prices are from heyreach.io/pricing. Both checked 11 November 2026, excluding tax. Your AI model's own costs are not in either figure.
This is not a like-for-like price. HeyReach's sender price buys an outbound system — campaigns, sender rotation, enrichment credits, a dedicated proxy per sender on Growth, white-label on Agency — that Spaces does not include and will not run. Spaces' price buys accounts an agent can work across four chat apps, mostly answering people who wrote first. If your goal is LinkedIn outbound volume, HeyReach's price is the price of that.
Where the difference shows up
1. Outbound at scale vs conversations people started
HeyReach is built for "multichannel outreach campaigns across multiple LinkedIn accounts simultaneously", with unlimited campaigns, every LinkedIn action, sender rotation inside per-sender daily limits and a unified inbox. (llms.txt, pricing)
Spaces is built for the other side: answering the people who message a business, following up with people who know it and stopping as soon as they reply, and handing over to a person when needed. Its own guidance says not to use it for "cold outreach at scale, bulk unsolicited messages, or bought or scraped contact lists", and on LinkedIn it "does not send bulk unsolicited messages or build lists of strangers to contact". (llms.txt)
If LinkedIn outbound is the job, choose HeyReach.
2. Both have MCP servers your agent can act through
HeyReach's MCP server (https://mcp.heyreach.io/mcp) connects Claude, ChatGPT and Codex by sign-in, and Cursor, VS Code, n8n, Make, Clay and others with an MCP key. Its tools read campaigns, leads and conversations, and write: create and start campaigns, add leads, and send_message — "Send a LinkedIn message". HeyReach notes that sending a message and starting or resuming a campaign are the actions with "a real effect outside HeyReach", and that "campaigns always run within HeyReach's sending limits". (developer docs, MCP)
Spaces' MCP gives an agent the chat accounts themselves, across four apps: read chats, reply, start a chat where allowed, schedule a message for a local time, and run routines triggered by a new message, a keyword, an accepted connection or no reply after N hours. Turn approvals on or use a draft-only key and sends wait for a person; one call pauses every send at once. It is on every plan, including Free, and an agent can set Spaces up itself from https://www.spacesos.com/agents. (llms.txt, pricing)
Rule of thumb: HeyReach's MCP gives an agent your LinkedIn outbound. Spaces' MCP gives an agent your customer conversations on four chat apps.
3. LinkedIn only vs four chat apps
HeyReach is LinkedIn: connection requests, messages, InMail, follow-ups, voice notes, profile views and post engagement, with email through Instantly, Smartlead and EmailBison. WhatsApp, Instagram and Messenger are not listed on the pages we checked. (llms.txt, pricing)
Spaces gives one agent the inboxes on Instagram, WhatsApp, LinkedIn and Messenger, plus TikTok for posts and comments, through one API and one MCP server (/mcp, or /mcp/whatsapp, /mcp/instagram, /mcp/linkedin, /mcp/messenger). Facebook Pages is coming soon. Email is not a live Spaces channel. (llms.txt)
On WhatsApp, Spaces links the number you already use by QR code, the way you link WhatsApp on a computer, and Spaces says there is no Meta approval, no message templates and no Meta message fees on that connection, and the number keeps working on your phone (Spaces WhatsApp API page). A new WhatsApp chat only goes to someone who has messaged the number before or is marked opted in. (limits)
4. Limits that protect the account
HeyReach keeps each sender "within their daily limits and safe usage levels" and gives each Growth sender a dedicated residential proxy; Agency and Unlimited plans bring their own proxies. (pricing)
Spaces sets LinkedIn limits by plan: up to 100 messages a day at least 20 seconds apart (replies to people who wrote in have no daily limit), 100 new chats a day, and connection requests at 100 a day and 150 a week on a free LinkedIn account, or 100 a day and 200 a week on Premium, Sales Navigator or Recruiter. 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. This lowers the risk of a platform restricting an account; it does not remove it. (llms.txt, LinkedIn API, safety)
5. Pricing: per sender or per account
HeyReach Growth is $79 a sender a month for 1–9 senders and $59 from 10 senders (up to 50), or $72 / $54 billed quarterly and $64 / $48 billed yearly. Agency is $999 a month for 25 senders or $1,399 for 50; Unlimited is $2,999 a month, capped at 300 senders. Teammates, VAs and clients are free; you pay per sender. (pricing)
Spaces has a Free plan — $0, no card, 1 connected account and 50 actions a day (sending stops until midnight at the limit; reading keeps working; no sequences or webhooks). Pay as you go is $9 per connected account a month, prorated, with 1,000 actions per account pooled across the workspace, then $5 per 1,000 ($4 above 100,000 extra, $3 above 1,000,000). Reading is always free, and you can set a monthly usage cap ($25 suggested). An action is a send, reply, new chat, post, comment, like, follow, invitation or profile lookup. (pricing)
Choose Spaces if
- You are building an AI agent that answers people, across WhatsApp, Instagram and Messenger as well as LinkedIn.
- Most of your messages are replies and follow-ups to people who know you: inbound leads, applicants, customers, people who commented on a post.
- You want one API and one MCP server for every chat account, with limits, pacing, warm-up, approvals and a pause switch built in.
- You want a Free plan to start and a per-account price that stays low at small counts.
Stay with HeyReach if
- You run LinkedIn outbound at scale across many sender accounts — that is what HeyReach is built for, and Spaces is not.
- You are an agency that needs workspaces per client, white-label and bring-your-own proxies.
- You want LinkedIn campaigns tied to Instantly, Smartlead or Clay, with enrichment credits.
- You want your AI to build and launch LinkedIn campaigns from Claude or ChatGPT.
Some teams will use both: HeyReach for outbound, Spaces for an agent that answers inbound conversations and the chats HeyReach does not reach.

FAQ
What is the best HeyReach alternative for an AI agent?
If your agent should answer and follow up with people on LinkedIn, WhatsApp, Instagram and Messenger, Spaces is the closest fit: one API and one MCP server, priced per account. If you want another LinkedIn outbound tool, Expandi and Waalaxy are the nearer swaps.
Does HeyReach have an MCP server?
Yes, at https://mcp.heyreach.io/mcp. Its tools can read conversations, send LinkedIn messages and create or start campaigns, within HeyReach's sending limits. (developer docs)
Can Spaces replace HeyReach for LinkedIn outbound?
No. Spaces refuses the same cold text sent to many people and does not build lists of strangers to contact. It can send connection requests with a note and follow up with people who know you, inside LinkedIn's limits. (llms.txt)
How much does HeyReach cost?
Growth is $79 a sender a month for 1–9 senders and $59 from 10, less billed quarterly or yearly. Agency is $999 a month for 25 senders; Unlimited is $2,999 a month for up to 300. (pricing)
How much does Spaces cost?
Free for 1 account and 50 actions a day, with no card. Then $9 per connected account a month, with 1,000 actions per account pooled, and $5 per 1,000 extra actions. Five accounts within included actions are $45 a month. (pricing)
Does HeyReach support WhatsApp or Instagram?
They are not listed on HeyReach's pricing, MCP or llms.txt pages, which describe LinkedIn plus email through integrations. Spaces connects WhatsApp, Instagram and Messenger alongside LinkedIn.
Will connecting an AI agent get my LinkedIn account restricted?
Every platform has its own rules. Spaces keeps each account inside daily limits, paces activity and warms new accounts up over four weeks. That lowers the risk but cannot remove it. See sending limits and account safety.
