Warmerly, both channels

The Platform API and webhooks on the Agency plan, docs, and an MCP server.

Expandi

Webhooks and native CRM integrations are listed, with no CRM named; an Expandi MCP is announced.

The short answer

Integrations, in one look.

Warmerly has an API and webhooks on the Agency plan, an MCP server on every plan, and mailbox connections. We found no CRM sync in Warmerly. Expandi is ahead on named connectors. Its help centre documents native HubSpot, Pipedrive and Salesforce integrations, a Smartlead integration, webhooks with Zapier and Google Sheets, reversed webhook calls that it calls the closest thing to a public API, and an MCP in beta for ChatGPT and Claude. Its pricing page says integrations are included but names none. Last checked 19 October 2026.

Showing every tile. Expandi is ahead on named CRM connectors: its help centre documents HubSpot, Pipedrive and Salesforce, and we found none in Warmerly.

Expandi: its Webhooks, CRM and MCP help collection, read 19 October 2026. Its pricing page names none of these, so the comparison table undersells its help centre. Warmerly: its docs for the API, webhooks, MCP and accounts. The tile counts are tiles listed here, not a score.

How Warmerly does it

Warmerly, in detail.

An API and 16 mailbox-health webhooks on the Agency plan, an MCP server on every plan, and connections for Gmail, Outlook, Zoho and SMTP and IMAP mailboxes. No CRM sync found.

An API, on the Agency plan

API keys and the API need the Agency plan ($179 a month). Keys start with wmv_, go in an X-Api-Key header to https://app.warmerly.com/api/v1, and each user can hold up to 10 active keys. The default limit is 60 requests a minute per key, adjustable from 1 to 120. Free, Starter and Growth get a 403 agency_plan_required error.
