Sendlane is a cloud-based marketing automation platform that helps eCommerce businesses engage customers through personalized email and SMS campaigns.
Sendlane is a cloud-based marketing automation platform that helps eCommerce businesses engage customers through personalized email and SMS campaigns. On Nagent, Sendlane is exposed as a fully-configurable marketing automation integration that any agent can call — 6 actions, and API key authentication. No code is required to wire Sendlane into your workflow — connect it once via the External Integrations panel and reuse it across every agent you build.
Agent builders use Sendlane 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 Sendlane 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 Sendlane, with input parameters and output schema. Drop these into any step of an agent built in Helix.
SENDLANE_GET_CAMPAIGNSTool to retrieve a list of email campaigns. Use when you need to fetch all campaigns with optional pagination.
Input parameters
Page number for paginated results (default is 1)

SENDLANE_GET_CUSTOM_FIELDSRetrieve a list of all custom fields in your Sendlane account. Custom fields allow you to store additional contact information beyond the standard fields. Use this tool to discover available custom fields, their IDs, names, tags, and types before creating or updating contacts with custom field data. Supports optional pagination via page and per_page parameters.
Input parameters
Page number for pagination. If not specified, defaults to page 1
Number of results per page. If not specified, the API uses its default limit
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
SENDLANE_GET_LISTSTool to retrieve all mailing lists. Use when you need to fetch or display all available contact lists with optional pagination.
Input parameters
Page number for paginated results (default is 1)
Number of lists per page (default is 1000)
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
SENDLANE_LIST_DELETETool to delete a mailing list. Use when you need to remove an unwanted list after confirming its list_id.
Input parameters
ID of the mailing list to delete.
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
SENDLANE_POST_LISTTool to create a new list. Use when you need to add a brand-new mailing list before sending campaigns.
Input parameters
The name of the list. This should be a descriptive, unique identifier for the mailing list (e.g., 'VIP Customers', 'Weekly Newsletter', 'Product Launch 2026').
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
SENDLANE_TAG_CREATETool to create a new tag. Use when you need to segment subscribers using labels.
Input parameters
Name for the new tag.
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 94 agents privately built on Nagent that already use Sendlane.
Build on Nagent
Connect Sendlane 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 Sendlane, and click "Connect Now." You'll authenticate with an API key — Nagent handles credential storage and refresh automatically. Once connected, Sendlane is available to any agent in your workspace.
No. Nagent provides no-code integration for every tool. Once Sendlane is connected, you configure its 6 actions directly in the agent builder UI — no API calls, no boilerplate, no schema management.
Helix — Nagent's agentic agent builder — lets you drop Sendlane 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 Sendlane event fires, the agent kicks off automatically.
Every Sendlane 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 Sendlane ships with 6 pre-built marketing automation actions, you can layer custom logic around them inside Helix — pre/post-processing steps, conditional branches, retries, or stitching Sendlane together with other connected tools.
