Works with Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This server provides 12 capabilities that interface natively with Claude, ChatGPT, Cursor, and any MCP client. No middleware. No custom integration required.
Manually moving contacts and checking campaign results is a huge time sink.
Today, to run a simple segmented campaign, you're stuck clicking through tabs: You export the list, filter out unsubscribes, manually copy the segment ID, paste it into the sender tool, and then run the send. It's tedious, prone to copy-paste errors, and takes forever.
With the eSputnik MCP Server, your agent handles the whole thing. You tell it the goal—'Send the Q3 promo to all 'High-Value' clients.' The agent handles finding the segment, validating the list, and sending the multi-channel message in a single, predictable call. You just get the confirmation.
eSputnik MCP Server: Trigger complex marketing flows.
Previously, setting up an automated follow-up meant building complex rules inside the platform's UI. Now, you can program that logic directly. You can use `trigger_event` to fire off a workflow that checks if a contact opened the initial email, and if not, sends a follow-up SMS—all through your agent's code.
The difference is control. You move from relying on the UI's rigid workflow builder to treating the entire marketing automation sequence as code. You execute it, and you get the confirmation.
What you can do with this MCP connector
eSputnik MCP Server gives your AI client full control over your marketing campaigns. You'll use it to manage omnichannel messaging across Email, SMS, Web Push, and Mobile Push from one place. You can send messages, pull contact lists, and manage complex workflows for segmenting and reaching specific customer groups. Your agent handles the whole process. It's built to run complex marketing automation sequences. You'll find these tools for: Managing Contact Segments: attach_to_group adds specified contacts to a designated eSputnik group or segment, and detach_from_group removes specified contacts from an existing group or segment. create_contact lets your agent make a brand-new contact profile, and get_contact fetches all the specific details for a single contact. search_contacts finds contacts using criteria like email or phone, while list_contacts pulls a full list of every contact in the system. list_groups shows you all the existing contact groups or segments. Discovering and Validating Contacts: list_unsubscribed pulls a list of all email addresses that unsubscribed from marketing emails. Sending Multi-Channel Messages: send_smart_send triggers a single, multi-channel message send, routing content simultaneously through SMS, Email, Web Push, and Mobile Push channels to a target audience. Executing System Events: trigger_event generates a system event that activates pre-configured automation workflows within eSputnik. Monitoring Campaign Delivery: get_message_status checks the current delivery status of a message using its unique ID. Account Info: get_account_info retrieves high-level metadata about your eSputnik account and organization settings.

How eSputnik MCP Works
- 1 Tell your AI agent the goal: e.g., 'Send a welcome sequence to all new leads in the 'VIP' group.'
- 2 The agent calls
list_groupsto find the 'VIP' group ID, then callsattach_to_groupto ensure the target contacts are correctly assigned, and finally callssend_smart_sendwith the campaign payload. - 3 The agent receives confirmation of the campaign launch, and can subsequently call
get_message_statusto track the delivery progress.
The bottom line is you use your AI client to run multi-step marketing processes by calling specific eSputnik tools sequentially.
Who Is eSputnik MCP For?
This is for marketing operations managers and growth engineers who live in the automation layer. If your job involves manually moving contacts between lists, checking campaign performance dashboards, or coordinating sends across email, SMS, and push, you need this. It replaces the dashboard click-through experience with direct API control.
They use this to segment large lists, ensuring only opted-in contacts receive promotional materials, and then triggering the corresponding multi-channel campaign via send_smart_send.
They use this to build complex user journeys—for example, if a user fails to open an email, the agent automatically calls send_smart_send to trigger a follow-up SMS.
They use this to maintain data integrity, calling create_contact or update_contact whenever a new lead source requires manual grouping or data entry.
What Changes When You Connect
- Go beyond basic sends. Use
send_smart_sendto send a message across SMS, Email, and Web Push simultaneously. This means you hit the user on multiple channels without writing complex API calls yourself. - Segment contacts instantly. Instead of manually updating groups, your agent calls
attach_to_groupordetach_from_groupto put people into the exact segment needed for the campaign run. - Build automated sequences. You don't just send a message; you build a flow. If the agent calls
trigger_event, it activates complex, pre-built workflows (like 'wait 2 days, then send SMS') that keep your campaigns running. - Maintain data hygiene. Quickly check who's opted out by calling
list_unsubscribed. This prevents your agent from accidentally sending messages to invalid or unsubscribed addresses. - Improve debugging. When a campaign fails, use
get_message_statusto check the delivery status. You immediately see if the message was delivered, bounced, or if the recipient never opened it. - Find people fast. If you only know a partial detail, use
search_contactsto find the contact record, then useget_contactto pull all their details for the next step.
Real-World Use Cases
Re-engaging Dormant Subscribers
A marketing manager needs to re-engage users who haven't opened emails in 6 months. They ask their agent to find all contacts using search_contacts with specific filters, check their status using get_contact, and then trigger a high-priority follow-up sequence by calling send_smart_send targeting the whole list.
Onboarding a New Client Group
A sales ops team needs to move a handful of new leads into the 'Platinum Tier' segment. They instruct their agent to first call list_groups to confirm the 'Platinum Tier' ID, then use create_contact for each new user, and finally use attach_to_group to officially segment them.
Handling Campaign Failure Mid-Run
A campaign fails because the target group needs to be updated. The agent first calls list_groups to find the correct segment name, then calls detach_from_group for the wrong contacts, and finally calls attach_to_group to correct the list before re-running send_smart_send.
Running a Post-Sale Audit
The team needs to confirm the status of a large batch of messages sent last week. They use get_message_status with the batch IDs to confirm delivery success, and then call list_unsubscribed to make sure no one was accidentally included in the next send.
The Tradeoffs
Calling listing tools sequentially
Manually running list_contacts to get all IDs, then running list_groups to get all segment names, and then iterating through both lists to build a payload. This is slow and fails if one list is massive.
→
Instead, use list_groups to find the segment ID, and then use search_contacts or list_contacts with the group filter to pull the necessary contact list directly. This is cleaner and more reliable.
Assuming contact data is fresh
Sending a campaign using the results from list_contacts without checking if the recipient has recently unsubscribed. This results in bounces and poor deliverability rates.
→
Always call list_unsubscribed first. Filter out those addresses before running any send command, ensuring compliance and maximizing delivery rates.
Treating sends as one-off actions
Calling send_smart_send and assuming the job is done. You have no way to know if the message actually hit the inbox or if it bounced. This leaves you blind.
→
After sending, immediately call get_message_status with the returned message ID. This confirms delivery and gives you the full status report for the campaign.
When It Fits, When It Doesn't
Use this server if your core process involves moving people through defined marketing stages or coordinating messages across multiple channels. You need to know who gets the message, when they get it, and how it gets delivered. Don't use this if you only need to manage simple contact records (e.g., just creating a record). For simple record management, the create_contact tool is enough. But if the goal is execution—running the campaign—you need the orchestration power of send_smart_send and the segmentation of attach_to_group. If you only need to read data, search_contacts is sufficient. If you need to build complex, multi-step workflows, you need to chain calls: list_groups -> search_contacts -> send_smart_send.
Common Questions About eSputnik MCP
How do I check if a message sent via eSputnik was delivered? +
