Super Send

Official MCP Paid, self-serve Engagement & Outbound RESEARCHED Checked 2026-09-07 CLI: supersendtx
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: supersend.io · entry id 02-super-send · source 02-engagement-outbound.md line 274

What it does
Cold email sequencing platform providing dedicated, warmed sending infrastructure with adaptive pacing based on live deliverability signals.
AI features, separated from automation with an AI label on it
"AI Bounce Analysis" categorizes send failures (bad address, server block, temporary failure) - genuinely ML-classification per vendor. "AI-categorized" inbox auto-sorts replies across many senders. Adaptive pacing/placement testing is described as signal-driven automation, not explicitly AI.
RevOps role
Dedicated sending-infrastructure layer for outbound email, positioned as an infrastructure/deliverability specialist rather than a full sequencing+CRM platform.

The vendor ships and maintains the server itself. A wrapper built by Zapier, Composio or a similar third party does not count as official. The status was established by hand on 2026-09-07. On 2026-09-04 the recorded URL served a documentation page, not an MCP endpoint. That is where to read about the server, not where to connect to it. An agent needs the second.

a fixed catalogue the vendor publishes

A tool below is one the server NAMES. Nobody has called it. That is the same two tier honesty rule the rest of the directory runs on: a named tool is research, and BENCH-TESTED stays the only claim that anybody ran anything.

141 of the 741 entries that record an official or community MCP server carry a harvested tool list. The other 600 are unmeasured, which is not the same as empty. Harvest last run 2026-09-27. Every name across every server is on the tools index.

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

No GitHub organisation could be tied to supersend.io with evidence on 2026-09-08.

Recorded by the harvest: github candidates were seen but none passed the evidence rules.

3 candidate accounts seen and rejected by the evidence rules: Super-Send, SpacePayafrica, MeetContactsApp. A name match alone is never accepted; the account has to point at the vendor domain.

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
Vendor's own MCP docs state the MCP server is a paid service with no free tier. Smaller/lesser-known player than most others in this sweep, but has a real vendor-hosted, documented MCP server - more than several larger competitors (Klenty, Outplay, Mailshake, QuickMail) have. 2026-09-07: https://mcp.supersend.io/mcp returned 401 with a JSON-RPC body: {"jsonrpc":"2.0","error":{"code":-32001,"message":"Missing or invalid credentials. Use Authorization: Bearer <key> or X-Supersend-Api-Key: <key>..."}} (https://mcp.supersend.io/mcp).
