How Warmerly does it

Warmerly, in detail.

An API and health webhooks for Agency, MCP for everyone, and no CRM connectors.

01

An API, on Agency

API keys and the API need the Agency plan ($179 a month). The default limit is 60 requests a minute per key.

02

16 mailbox-health webhooks

Signed POSTs about mailbox health. They do not cover opens, clicks or replies. Agency only.

03

An MCP server on every plan

The MCP server lets Claude, ChatGPT, Claude Code and Cursor read and act in a workspace after an OAuth sign-in. It needs no API key.

04

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.

What QuickMail does not say

We looked, and found no statement on these. That is about its published pages only, not about the product.

  • The plan an MCP connection needs
  • Salesforce sync, which its help centre covers only as BCC logging
  • The plan Zapier needs, which its help page does not name

Where the sources disagree

We report each version rather than pick one.

  • Its home page lists HubSpot and Pipedrive sync without a plan, while its subscription help page marks them as Growth and Agency only. We follow the help page.

In practice

What it means for you.

Our reading of the facts above. Not a promise, and not the only reasonable reading.

1

Which events do you need?

Warmerly's webhooks tell you about mailbox health. QuickMail's tell you about opens, replies and bounces.

2

The default limits are close

60 requests a minute works out at 10 every 10 seconds, the same pace as QuickMail's limit.

3

CRM first

If your sales team lives in HubSpot or Pipedrive, QuickMail's native sync is a real advantage.

4

Where replies go next

QuickMail can push a reply into HubSpot or Pipedrive or fire a Zap. With Warmerly the route is the API on Agency or the MCP server, and there is no CRM sync to switch on.

5

Webhook scope differs

QuickMail's webhooks cover opens, clicks and replies. Warmerly's cover mailbox health only.

6

Rate limits are not alike

QuickMail allows 10 requests per 10 seconds, which is 60 a minute. Warmerly's default is 60 requests a minute per key, so the raw API allowance is the same size.

Who it suits
