How Warmerly does it
Warmerly, in detail.
An API and signed webhooks on the Agency plan, and an MCP server on every plan. We found no CRM sync.
01
An API, on the Agency plan
API keys need the Agency plan ($179 a month). Keys go in an X-Api-Key header, the default limit is 60 requests a minute per key, adjustable from 1 to 120, and each user can hold up to 10 active keys.

02
16 mailbox-health webhooks
Signed POST webhooks, 16 event types such as score_drop and auth_fail. They do not cover opens, clicks or replies. Agency only.

03
An MCP server on every plan
An MCP server lets Claude, ChatGPT, Claude Code and Cursor read and act in a workspace after an OAuth sign-in. Reads and writes share 60 calls a minute and no tool can start or resume campaign sending.

04
No CRM sync found
We searched for HubSpot, Pipedrive and Salesforce connectors and found them only in lead-data and marketing files, and no listed Zapier, Make or n8n app of its own.

05
Rate limits are written down
The default is 60 requests a minute per key, adjustable from 1 to 120, and each user can hold up to 10 active keys. The MCP server shares 60 calls a minute across reads and writes.

06
What the MCP server will not do
No MCP tool can start or resume campaign sending, so an assistant can prepare a campaign and a person still presses go. Access runs through an OAuth sign-in to one workspace or all of them.

05
MCP and CLI
The help centre has MCP articles for Claude, Clay, Visual Studio Code and Make. The home page says the MCP server lets AI agents "make decisions for you", and does not describe a human check.

Webhooks
The webhooks article says you choose the type of event that triggers a webhook, and does not name the events. It is dated September 2024.

07
MCP is set up per workspace
Each workspace has its own MCP connection URL and key, found under Integrations. Generating a new key changes the connection URL. The article says this suits agencies managing several clients.

What the MCP article leaves out
It names Claude, n8n, Clay, Visual Studio Code and Make as examples, and does not list the tools, the plans or any limits. We could not say what an assistant can read or change.

Setting up a webhook
Webhooks are made from Integrations, then Webhooks: a name, the URL, the campaigns it applies to and the event type. It goes live straight away and has an on and off toggle.

HubSpot in detail
The HubSpot articles describe 20 properties HeyReach creates, conversation notes saved on contacts and 12 LinkedIn activities logged against them.

Pricing page and home page, not the same list
The pricing page names Instantly and Smartlead as native integrations and gives Clay, RB2B, Trigify and HubSpot as examples. The home page adds EmailBison, n8n, Make and Zapier.

What HeyReach does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- Webhook event names
- API rate limits
- Plan requirements for the API in the help centre
- The events a webhook can listen to, or what it sends (the article names neither)
The numbers
Only what we could verify.

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
HeyReach connects to more of a typical stack
HubSpot and Clay are common asks, and Warmerly has neither.
Warmerly puts the MCP server on every plan
Including Free, with sending kept out of reach of the assistant.
If your CRM is HubSpot, this decides it
HeyReach logs LinkedIn activity, notes and properties there. Warmerly has no CRM sync that we found, so replies would be exported or moved by hand or through the API.
Warmerly's API is for building, not for syncing
It is useful when your own team writes code against campaigns and mailbox health. It is Agency only, at $179 a month, where HeyReach lists its API and webhooks on Growth.
Both tools have an MCP server, with different promises
Warmerly's has a written rate limit, a workspace scope and no tool that starts sending. HeyReach's home page talks about agents making decisions, and the help article we read does not say what is allowed.
Who it suits
