Stannp MCP with Claude: Automate Direct Mail Campaigns Through Natural Language
The short answer
Claude connects to Stannp through the Model Context Protocol, a secure standard that lets Claude use software with permissions you control. Once connected, a team member can describe a mailing in plain English, and Claude can prepare, send and track postcards or letters through Stannp, with people approving sends before they go out.
What is Stannp?
Stannp is an API-driven direct mail platform. It lets businesses send postcards and letters programmatically, so physical mail can be triggered by software rather than printed and posted by hand. Marketing teams, fundraising organisations, customer service teams and small businesses typically use it to reach customers by post, reminders, welcome packs and campaign mailings at scale.
How Claude connects to Stannp through MCP
The Model Context Protocol, or MCP, is an open standard that lets Claude securely use other software. Think of it as a universal adapter between Claude and a tool. Through it, Claude can read information from Stannp and take actions in it, using the access your organisation chooses to grant.
Once connected with a Stannp API key, Claude can typically look up mailing templates and recipient details, prepare postcard or letter jobs from a plain-language brief, check delivery status and report on how mail is progressing. Requests are handled in natural language, so staff do not need to learn the underlying interface for each task.
Permissions and approvals keep people in charge. Access is limited to what each workflow needs, and consequential actions such as sending a physical mailing or a batch to a large list can require a named person to approve first. Every action is logged so the team can review what was sent and when.
What you can automate
Welcome packs for new customers
When a new customer signs up, the system can trigger a personalised welcome postcard. Claude prepares the message from the customer record and sends it through Stannp for approval, helping new customers feel valued from their first week.
Win-back campaigns
Customers who have not purchased for a set period can be grouped into a mailing list. Claude drafts a tailored letter or postcard for each segment, and the marketing lead approves the batch before dispatch. Delivery is then tracked for follow-up.
Appointment and renewal reminders
Clinics, service providers and membership bodies can send physical reminders for appointments or renewals to people who prefer post. Claude pulls due dates from the booking or membership system and queues the correct letters through Stannp.
Fundraising and donor thank-you letters
Charities can send thank-you letters after each donation. Claude matches donor records to the right template, personalises the greeting and passes the batch to staff for sign-off, so acknowledgements go out promptly and accurately.
Campaign performance reporting
Marketing managers can ask Claude for a summary of which mailings were sent, delivered and when. Claude retrieves the delivery status from Stannp and presents a short, readable report that helps the team plan the next campaign.
An end-to-end workflow: Renewal reminder postcards from the CRM
TriggerA membership in the CRM is due to expire within 30 days.
Claude reads the list of memberships due to expire from the CRM, such as Microsoft Dynamics or a similar system.
Claude matches each member to the correct postcard template and fills in their name and renewal date.
The batch is sent to the operations manager in Microsoft 365 Teams for approval, with a count and sample preview.
Once approved, Claude submits the postcards to Stannp for printing and posting.
Claude records each mailing against the member's CRM record and checks Stannp for delivery status over the following days.
Any undelivered items are flagged to staff for follow-up.
OutcomeRenewals are chased consistently by post, staff spend less time on manual mail, and the team has a clear record of what was sent and delivered.
How we set it up
Free automation audit
We review how your team currently sends physical mail, identify the workflows worth automating and agree on the priorities together. There is no charge for this step.
Secure connection with an API key
We connect Claude to Stannp using an API key, which your organisation generates and controls. The key is stored securely and can be revoked at any time. Access is restricted to the actions each workflow needs.
Workflow design across your systems
We design the end-to-end process linking Stannp with your CRM, Microsoft 365, ticketing or other systems, and define where people must approve consequential actions.
Testing and launch with monitoring
We test the workflow against real past cases, check templates and personalisation, then launch with monitoring and audit logs turned on.
Team training and handover
We train your staff to brief Claude, review drafts, approve batches and read delivery reports, and leave you with clear documentation to run the system confidently.

Frequently asked questions
What does the Stannp MCP server do?
The Stannp MCP server lets Claude connect to your Stannp account and use it on request. Typically this means preparing postcards and letters, launching mail campaigns and checking delivery status. It acts as a secure bridge, so staff can give instructions in plain language rather than working through each step by hand.
Is connecting Claude to Stannp secure?
Yes, when it is set up carefully. Access uses an API key that your organisation controls and can revoke at any time. We limit permissions to what each workflow needs, require approval for physical sends and keep audit logs, so you can see every action taken.
What can Claude do with Stannp once connected?
Claude can typically look up templates and recipient details, draft personalised postcard or letter jobs, submit them for sending, track delivery and summarise results. Consequential actions such as sending a batch can be set to require a named approver before they go ahead.
How long does setup take?
Timelines depend on the number of workflows and the systems involved. A single, well-defined mailing workflow is often ready within a few weeks, including testing and training. Larger programmes linking several systems typically take longer. We confirm the timeline during the free automation audit.
Which plan or permissions do I need?
You need a Stannp account with API access enabled and an API key generated for the connection. The exact account level and permissions depend on your Stannp setup, so we check these during the audit and confirm what your team should have in place before we begin.
