No CRM sync found
We searched the code and docs for HubSpot, Pipedrive and Salesforce connectors and found none, and no Warmerly app of its own on Zapier, Make or n8n.

05
Signed webhooks
The 16 mailbox-health webhooks are signed POST requests, so a receiving system can check they came from Warmerly. They report mailbox health, not opens, clicks or replies.

06
Claude, ChatGPT and Cursor
The MCP server accepts an OAuth 2.1 sign-in from claude.ai, ChatGPT, Claude Code and Cursor. A grant covers one workspace, or all your workspaces if you choose that on the consent screen.

07
Stateless by design
The server uses stateless streamable HTTP and rebuilds its tool set on every request, because there is no Redis to hold sessions.

What SmartReach does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- Which plans include the API
- API rate limits
- A webhook event list on the pages we read
- The authentication method and base URL, which sit on a later page
- API rate limits
- A list of webhook events
Where the sources disagree
We report each version rather than pick one.
- Its add-on list shows CRM Integrations at $29 a month per CRM, while its FAQ says CRM integrations are included on every plan above Basic with no separate fee.
- Its Zapier article says 5,000+ connectable apps in one place and over 8,000 in another.

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
A CRM changes the answer
If your sales team lives in HubSpot or Salesforce, SmartReach syncs there and Warmerly does not.
Warmerly's strength is AI assistants
The MCP server lets Claude or ChatGPT act in a workspace after a sign-in, on any plan.
A HubSpot team
If HubSpot is where deals live, SmartReach's native sync starts at Plus ($89 or $99), and the add-on list also shows $29 a month, so check which applies. With Warmerly you would move data by CSV or scripts.
A developer on a small team
Warmerly's API needs Agency at $179 a month. SmartReach's help centre documents a REST API without naming the plan. If you only need to script a few things, ask support before you pay.
Working from an AI assistant
With Warmerly's MCP server, an assistant can read and act in a workspace after one sign-in, on any plan, with no API key. SmartReach's pages we read describe nothing equivalent.
Zapier app counts
SmartReach's Zapier article says 5,000+ apps in its introduction and over 8,000 in its body, and its home page says 8,000+. We quote it as 8,000+ per its home page.
Telling Slack about a reply
On SmartReach a Zap can trigger when a prospect replies and post to Slack, using the Zapier key from Team settings. On Warmerly the route is the API or MCP on the plans that include them, since there is no Zapier app.
What the 60 a minute limit allows
Warmerly's default of 60 requests a minute per key is one a second on average, enough for most reporting scripts but not for a bulk import of 10,000 records in a minute.
Who it suits
Pick the one that fits.
Warmerly
Warmerly is the better fit if
- You want to drive your workspace from Claude or ChatGPT
- You only need mailbox-health webhooks and an API on Agency
- You want to drive Warmerly from an AI assistant without a key

SmartReach
SmartReach is the better fit if
- You need native CRM sync
- You need Zapier or a Calendly link in your cadence
- Your CRM is Salesforce, HubSpot, Pipedrive or Zoho and you want a native link
- You want Zapier on every plan
