Userlist is a full-stack email automation platform designed for SaaS companies, enabling targeted behavior-based campaigns through email and in-app messages. On Nagent, Userlist is exposed as a fully-configurable marketing automation integration that any agent can call — 2 actions, and API key authentication. No code is required to wire Userlist into your workflow — connect it once via the External Integrations panel and reuse it across every agent you build.
Agent builders use Userlist to automate the kinds of tasks marketing automation teams previously handled manually. Concrete examples — each one is a single agent step in Nagent — include:
Every action and trigger is paired with a structured input/output schema (visible in the sections below), so when you wire Userlist into Helix — our agentic agent builder — the editor knows exactly what each step expects and produces. Configure once, deploy anywhere across your Nagent agents.
Every operation an agent can call against Userlist, with input parameters and output schema. Drop these into any step of an agent built in Helix.
USERLIST_DELETE_COMPANYTool to delete a company from Userlist. Use when you need to remove a company by its unique identifier after verifying it.
Input parameters
Unique identifier of the company to delete (must not contain '/').
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
USERLIST_PUSH_RELATIONSHIPTool to create or update a relationship between a user and a company in Userlist. Use after confirming valid user and company identifiers.
Input parameters
Additional custom data for the relationship (key-value pairs).
Identifier of the user.
Identifier of the company.
ISO-8601 timestamp for when the relationship was established.
Type of relationship: member, admin, or owner.
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
No publicly available marketplace agent is found using this tool yet. There are 93 agents privately built on Nagent that already use Userlist.
Build on Nagent
Connect Userlist to any Nagent agent in minutes — no API key management, no boilerplate. Just configure and deploy.
The five questions agent builders ask before adopting a new integration.
Open the External Integrations panel inside Nagent (app.nagent.ai/externalIntegration), find Userlist, and click "Connect Now." You'll authenticate with an API key — Nagent handles credential storage and refresh automatically. Once connected, Userlist is available to any agent in your workspace.
No. Nagent provides no-code integration for every tool. Once Userlist is connected, you configure its 2 actions directly in the agent builder UI — no API calls, no boilerplate, no schema management.
Helix — Nagent's agentic agent builder — lets you drop Userlist steps into any workflow visually. Pick an action (e.g., one of those listed above), fill in the inputs (Helix knows the required vs. optional schema for each parameter), and connect it to upstream/downstream steps. Triggers run as the entry point of an agent, so when a Userlist event fires, the agent kicks off automatically.
Every Userlist action and trigger ships with a fully-typed schema — input parameters with name, type, required flag, and description, plus the output payload shape. The schemas are documented in the sections above. Helix uses these schemas to validate your configuration at build time and to type-check the data flowing between steps.
Yes. While Userlist ships with 2 pre-built marketing automation actions, you can layer custom logic around them inside Helix — pre/post-processing steps, conditional branches, retries, or stitching Userlist together with other connected tools.
