Manage Instantly cold-email campaigns, leads, sending accounts and the Unibox over API v2.
Instantly ships in the w6w first-party pack. It declares 38 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.
io.w6w.instantlyInstantly is a cold-email outreach platform: campaigns of scheduled email sequences sent from a pool of connected sending accounts, with lead tracking, interest-status labeling and a shared inbox (Unibox) for replies. This app covers the run-and-read path a workflow actually needs against Instantly’s API v2 — create, launch, pause and read back campaign analytics; add, search, update and move leads between campaigns and lists; list and manage the sending accounts a campaign draws from, including their warmup and daily-volume analytics; and read, reply to or forward the emails a campaign receives.
Every path, verb and field was verified against Instantly’s own OpenAPI 3.0 document rather than inferred from a sibling app or a community integration. Two vendor realities shaped the design: creating a sending account means handing Instantly that mailbox’s own IMAP/SMTP password as a request field (a legitimate, vendor-required exception to the credential-only-in-sign rule, since that password belongs to the mailbox being provisioned, not to this app’s own Connection), and API keys are scope-gated per resource, so a key scoped away from Campaigns will see the health probe refuse with a distinguishable ‘insufficient scope’ message rather than a bare failure.
Three routes to the same 38 actions. The Workflow tab is generated from Instantly's own manifest and carries its real ids, so it is copy-pasteable; the Code and CLI examples are the same call for any action on any app, so every app-specific value in them is a blank you fill in.
account-create Connect a mailbox to the workspace over IMAP/SMTP as a sending account.
account-daily-analytics-get Emails sent per day, per sending account. Defaults to the trailing 30 days.
account-delete Permanently disconnect a sending account. Returns its last state.
account-mark-fixed Mark a sending account's error as resolved so Instantly resumes sending from it.
account-warmup-analytics-get Get per-day and aggregate warmup send/receive/inbox/spam counts for sending accounts.
campaign-activate Start a draft campaign or resume a paused one — Instantly uses the same endpoint for both.
campaign-analytics-get Get engagement analytics for one, several, or (leaving id/ids empty) every campaign in the workspace.
campaign-analytics-overview-get Get aggregate engagement and interest-status totals across one, several, or every campaign.
campaign-create Create a campaign. A schedule is required even for a campaign you plan to launch later.
campaign-delete Permanently delete a campaign. Returns the deleted campaign's last state.
campaign-duplicate Create a copy of a campaign. Defaults the new name to "<original name> (copy)" when left empty.
campaign-list List campaigns in the workspace, newest first, with optional name search and status filters.
campaign-sending-status-get Explain why a campaign is not sending, or is sending slower than expected.
email-list List emails a campaign sent or received (the Unibox). Rate limit: 20 requests/minute, tighter than this app's other actions.
lead-bulk-add Add up to 1,000 leads to a campaign or a list in one call. Validates emails and checks them against blocklists and existing leads.
lead-bulk-delete Delete multiple leads from a campaign or list, optionally filtered by status or specific IDs.
lead-move Move (or copy) leads matching a filter to a different campaign or list. Returns a background job; the move runs asynchronously.
lead-update-interest-status Set (or clear) a lead's interest status by email — the same action as dragging a lead between CRM columns in the app.
workspace-get Read the current workspace's details. Requires the workspaces:read scope specifically.
A workflow step names the app and the action, and the editor fills in the
connection when you pick one. This is the Step shape from the
workflow spec, carrying Instantly's real ids.

Every app-specific value here is a blank you have to fill in. An
app action is reached through the connection that authenticates it, so the
address is a connection id, not the app id — and connections belong to your account,
so a public page cannot know yours. Create one for Instantly, then fill in
the three blanks: conn_YOUR_CONNECTION_ID, the action key, and the
parameters that action declares. The call itself is real — the shape is transcribed
from the studio's own snippet builder, which prints the same kind of blanks — but
nothing in it is specific to Instantly. The Workflow tab is where this app's
real ids are.

One MCP endpoint exposes every app, function and workflow the caller is entitled to, as tools it can discover and run. Access is granted per team while we onboard.
One tool call{
"name": "w6w_invoke",
"arguments": {
"ref": "app:io.w6w.instantly#account-create",
"input": {
"email": "<email>",
"first_name": "<first_name>",
"last_name": "<last_name>"
}
}
}
Every tool names its target with a single ref. The
app: form above doesn't name a connection at all — the
host resolves which of the caller's Instantly connections to sign
with, and refuses rather than guesses when the answer is ambiguous.
The token is attached host-side, at the moment of the call. It is never a tool argument, never in the model's context, and never in a transcript — so a prompt injection has nothing to exfiltrate.
Tools are derived per end user from what that person has actually connected and is entitled to — not one shared bot identity carrying the union of everyone's access.
Multi-step work runs on the workflow engine and returns a run handle the agent can poll — retries, branching and state survive the conversation that started them.
Instantly's declared health checks are on the surface too, so an agent can tell "the vendor is down" from "your credential expired" before it burns a retry on either.
The MCP surface is part of the hosted platform. Instantly itself is MIT, and the runtime that executes it is source-available (FSL).
Instantly declares its own checks, so its health is a property of the app rather than something the host guesses at.
No machine-readable or HTML status page was found for Instantly as of 2026-08-29 (status.instantly.ai does not resolve; both statuspage.io subdomains one would guess redirect to statuspage.io's own homepage rather than a claimed page), so this app declares the absence rather than guessing at an undocumented endpoint.
Instantly documents fixed, workspace-wide ceilings (100 requests/second, 6,000 requests/minute, shared with API v1) but exposes no response header or endpoint that reports current consumption against them (verified live 2026-08-29), so there is nothing to probe ahead of a 429.
