No MCP found Paid, self-serve Email Deliverability RESEARCHED Checked 2026-09-02
RESEARCHED Facts from public sources with URLs. No usage claims. Nobody has run this tool. The other tier is BENCH-TESTED, which means Andrew personally ran the tool on a stated date and cannot be bought at any price. Across the whole directory that count is 1.

Vendor: warmy.io · entry id 09-warmy-io · source 09-email-deliverability.md line 235

What it does
Email warmup and deliverability platform with an "AI-driven engagement engine" - customizable warm-up topic/language selection, works across Gmail, Outlook, Zoho, and Amazon SES, with a real-time webhook/Slack-connected API for adjusting warm-up speed, volume, and timing programmatically.
AI features, separated from automation with an AI label on it
Vendor markets the engagement engine as "AI-driven" and the warmup content as "fully personalized" per message - no independent breakdown of what is model-generated versus templated was found; treat as vendor-stated.
RevOps role
Deliverability-maintenance layer comparable to Mailreach/Warmup Inbox, differentiated on enterprise-sender topic/language customization and webhook-driven programmatic control.

Command line

No CLI found by the 2026-09-27 harvest across vendor docs, npm, PyPI, Homebrew and GitHub. That is a probe result, not proof of absence.

Access gate
Gate bucket
Paid, self-serve
Can a solo operator reach it
Yes, by paying, no sales call

api_gate, verbatim from the file:

paid - API is a distinct product tier ("Warmy API") rather than bundled into every plan by default, per the vendor's own product page.

API documentation

No documentation URL recorded.

727 of 1252 entries are in the same position. Blank is legal and it is published as blank.

GitHub health

Not measured. github_url, github_stars, github_last_commit and github_archived are null on every entry in this build.

The refresh rail specced in SPEC section 7.2 has not been run. An unstamped star count is a lie, so nothing is shown rather than something stale.

On GitHub

github.com/Warmy-io tied to the vendor by rule 3, account website www.warmy.io has the vendor's domain, confidence strong

Kind is a heuristic guessed from the repository name, topics and description, not a fact the vendor stated. A repository count is activity, not a verdict. Read 2026-09-08.

Jobs it can do

A job tag means the vendor says the tool does this. It is not a test result, not proof the capability is reachable through the tool's MCP server, and not proof it is available on the gate this entry records.

Tagged by machine-pass on 2026-08-25 against the closed 56 job vocabulary. 271 of 1,252 entries carry at least one tag; 849 tags are assigned in total.

Notes, verbatim from the file
A search result mentioned a separate, apparently unrelated tool called "mailX" (a free SPF/DKIM/DMARC/blacklist checker) as having "API and MCP access" - that is a different product from Warmy.io and was not pursued further here since it fell outside this file's named seed list; flagged only to avoid future conflation. No MCP server found for Warmy.io itself. 2026-09-02: re-checked, mcp_status stays none-found. A second conflation risk is now documented: the official MCP registry entry com.warmysender/mcp (https://warmysender.com/mcp, 77 tools, streamable HTTP, Bearer ws_ API key or OAuth) belongs to WarmySender, whose own homepage states "WarmySender and Warmy.io are completely separate and unaffiliated companies" that "share no code, data, or ownership". https://www.warmy.io/product/api/ still has no MCP mention. Do not cite WarmySender for Warmy.io.
