Managing mailing lists shouldn't feel like juggling three different spreadsheets.
Today, managing a mail campaign means logging into the CRM to pull names. Then you export that CSV, open it in Excel to scrub bad addresses, and finally upload the cleaned list somewhere else just so your mailing service can see it. It's tedious clicking and constant copy-pasting.
With this MCP Server, you skip all that. You tell your agent: 'Get me a clean list of all Platinum members.' The agent uses `list_mailing_recipients`, processes the data internally, and gives you a ready-to-use result—all in one chat window.
Stannp MCP Server: Automate physical mail workflows.
The old way required filing tickets, calling support lines just to confirm if a specific address was valid, or manually checking the campaign dashboard every hour for updates. It's slow and requires people sitting there watching screens all day.
Now, you ask your agent what you need done. The agent executes `list_direct_mail_campaigns` instantly and gives you actionable data points—like total pieces mailed this month or average response rates—without leaving the chat.
What your AI can actually do with this
Listen, you connect your Stannp account to your AI agent on Vinkius. This lets your agent handle direct mail campaigns—physical letters and postcards—without you ever having to touch a web dashboard or write code. You just talk to it like talking to a teammate; your agent handles the rest of the heavy lifting.
Sending Mailers
When you need to send physical mail, your agent uses specific tools. To blast out personalized letters, it calls create_physical_letter, which sends either single letters or bulk runs based on what you tell it. If postcards are what you're running, the agent executes create_postcard to create and dispatch those. You can also track these efforts; for a rundown of every letter sent or drafted, check list_letters.
Similarly, if you need postcard history, run list_postcards.
Managing Your Contacts
You've got records in the system that your agent manages. If you need to build out the mailing list, tell it to use create_recipient, and it adds a brand new contact record right into the database. To see who’s already in the mix, it generates a full roster using list_mailing_recipients.
Need details on one specific person's address? The agent runs get_recipient and pulls all available data for that single mailing address.
Tracking Campaigns and Status
Your AI client keeps tabs on everything. If you want to know about past or planned campaigns, the agent uses list_direct_mail_campaigns to pull up a history by name or date range. For deep-dive status reports on one specific campaign ID, it calls get_campaign, providing all the metadata and current status you need.
You can also check the full details of any single letter that was sent or even just drafted by running get_letter.
Monitoring Finances
It’s important to know your limits before you start mailing things out. To see what money you've got left in your prepaid account and what your spending cap is, simply run the get_account_balance tool. This keeps you from getting stuck halfway through a big campaign because of an unexpected balance issue.

Here's how it actually works
The bottom line is you stop writing API code. You just talk to your AI client, and it executes the complex mail workflow for you.
Subscribe to this server on Vinkius and input your Stannp API key into your AI client. This grants your agent access to all 11 tools.
Tell your agent what you need done (e.g., 'Send postcards to the top 50 clients'). The agent determines the necessary sequence of tool calls.
The agent executes the plan—for instance, it first uses list_mailing_recipients and then passes those IDs into create_postcard—and reports the final status.
Who is this actually for?
Marketing Operations Specialists who get sick of switching between CRMs, mailing service dashboards, and spreadsheets. Campaign Managers dealing with high volumes of physical outreach need this. If your job involves sending anything printed—from thank-you notes to annual reports—and you hate manual data validation, this is for you.
Uses the agent to validate mailing lists with list_mailing_recipients and then queues bulk sends using create_physical_letter, all without ever opening the web console.
Checks campaign performance by calling get_campaign to verify delivery status, or uses list_letters and list_postcards to audit recent sends.
Needs quick spending checks before a big push. They use get_account_balance first, then instruct the agent to send materials using create_postcard.
What Changes When You Connect
Instantly monitor your budget with get_account_balance. You know exactly how much you can spend before the agent initiates any large send, preventing unexpected overages.
Build complex campaign reports. Use list_direct_mail_campaigns to pull metadata and status across dozens of outreach efforts in one query.
Perfect for personalized follow-up. Instead of manual lookups, use get_recipient combined with the agent to ensure every single address is current before sending a letter via create_physical_letter.
Streamline list building. The list_mailing_recipients tool pulls your entire contact database into the conversation, letting you filter and prep for sends without exporting a CSV.
Full audit trail available. Need to prove when something was sent? Use list_letters or list_postcards to access a history log of every physical piece mailed.
See it in action
Auditing the last quarter’s outreach.
The coordinator needs to know how many letters were sent in Q2. They prompt their agent with: 'Show me all my mail activity from April to June.' The agent runs list_letters and list_postcards, giving a consolidated count, saving hours of manual record-checking.
Running a targeted local promotion.
The marketing team wants to send postcards only to high-value clients in one zip code. They first run list_mailing_recipients to get all addresses, and then instruct the agent: 'Filter that list for ZIP 90210, then send a postcard.' The entire process runs in two tool calls.
Checking compliance before a big push.
Before launching a massive campaign, the Campaign Manager asks the agent to run get_account_balance. This immediately shows the current spending cap. If it’s low, they stop and fix the budget issue rather than wasting money on sends.
Creating a new mailing segment.
The team identified a group of contacts that need special handling. They use list_mailing_recipients to pull names, and then call create_recipient with updated details or missing information for those specific people.
The honest tradeoffs
Sending mail without checking the list.
A user tries to send a letter by just typing 'Send letters to everyone.' This fails because the agent doesn't know which records are active or if they need scrubbing first.
Always run list_mailing_recipients first. Then, use the resulting list data and pass it into create_physical_letter. This guarantees you are targeting only valid records.
Ignoring campaign status reports.
The user sends a major campaign but never checks if it hit its goal or if there were delivery issues, assuming everything went smoothly.
After sending materials, use list_direct_mail_campaigns to review the full metadata. This shows response rates and detailed status updates you need.
Trying to manage addresses manually.
The user tries to copy-paste a single address into a form on the web dashboard, which is slow and prone to typos.
Use get_recipient if you only need one person's info. If you need to update or check multiple addresses, use list_mailing_recipients and ask the agent to handle the data changes.
When It Fits, When It Doesn't
Use this server if your goal is physical, printed communication—letters, postcards, anything that hits a mailbox. You must be able to measure success by physical delivery count or response rate.
Don't use it if you are only sending emails, running ad campaigns on social media, or managing digital files. For those tasks, look for an Email Marketing Platform MCP Server instead. If your core need is simply reading data (like viewing a spreadsheet), then this server won't help; you need a database connector tool.
If the process requires listing contacts and sending physical items, always follow this sequence: list_mailing_recipients -> [Review/Filter] -> create_physical_letter. This structured approach maximizes control and prevents incomplete sends.
Questions you might have
How do I check my remaining mailing budget with Stannp MCP Server? +
You use the get_account_balance tool. This immediately pulls your current credit balance, so you know exactly how much spending power is left before starting any campaign.
Can I send a postcard to only one specific client using Stannp MCP Server? +
Yes. First, use get_recipient to pull all the necessary details for that single person. Then, instruct your agent to run create_postcard with those specific credentials.
What if I need to update a contact's address before sending mail? +
You should first use list_mailing_recipients to see the current data. If an address is wrong, you can tell your agent to create or modify that record using the create_recipient tool.
Does Stannp MCP Server track my sent letters? +
Yes. You access a full history log by calling list_letters. This shows you every letter that has been drafted or successfully mailed through the system.
How do I retrieve the status and metadata for a direct mail campaign using get_campaign? +
The agent retrieves detailed records for any specified Campaign ID. You see the total pieces sent, delivery rates, and whether the campaign is currently active or finalized.
What should I do if the create_physical_letter tool returns an error? +
The server sends a specific error code detailing the failure. This usually points to bad recipient data, invalid formatting, or billing issues; check your account status first.
How do I list and view all my mailing recipients using list_mailing_recipients? +
You call list_mailing_recipients. This pulls a comprehensive manifest of every contact in your system. From this result, you can select the IDs needed for targeted sends or record creation.
What happens if my Stannp API key expires while using any tool? +
The server will fail and return a clear authentication error message. You must update your Stannp API Key within Vinkius with a fresh, active credential before running any operations.
