Laposta MCP with Claude: Manage Newsletters and Subscribers in Plain Language
The short answer
Claude works with Laposta through the Model Context Protocol (MCP), an open standard that lets Claude use the tool securely. Once connected with an API key, Claude can read subscriber lists, prepare and send campaigns, review reports and organise contacts. Your team sets the permissions and approves important actions before they happen.
What is Laposta?
Laposta is a newsletter platform from the Netherlands. Teams and businesses use it to create professional newsletters, build and manage mailing lists, and send email campaigns. It is designed to keep email marketing simple and efficient, so marketing staff can focus on content and audience growth rather than technical set-up. Small businesses, associations and communications teams are typical users.
How Claude connects to Laposta through MCP
The Model Context Protocol, or MCP, is an open standard that acts like a universal adapter between Claude and other software. It lets Claude securely read information from a tool and take actions in it, using permissions that your organisation controls. Laposta also offers a direct API, and the consultancy chooses the most suitable route for each team.
Once Claude is connected to Laposta, people can ask for things in ordinary language. For example, a marketer might ask Claude to list subscribers who joined in the last month, summarise how the last newsletter performed, or draft a campaign for review. Claude can organise contacts into groups and pull reports on opens and clicks, saving time on routine admin.
Permissions and approvals keep people in charge. Access is limited to what each task needs, and sending a campaign or changing a large list can require a named person to approve it first. Activity is logged, so the team can see what Claude did and when. Nothing reaches your subscribers without a human decision.
What you can automate
Monthly newsletter production
Claude drafts the newsletter from approved articles and news items, prepares the layout in Laposta, and sends a preview to the editor. The editor reviews, makes changes and approves the send. This shortens production from days to hours for many small communications teams.
Subscriber list clean-up
Claude reviews the list for duplicate addresses, inactive contacts and incomplete records, then proposes a cleaning plan. The marketing manager confirms which contacts to remove or move. Regular clean-up tends to improve deliverability and keeps reporting accurate.
Campaign performance reviews
After each send, Claude pulls the open, click and unsubscribe figures and compares them with previous campaigns. It highlights which subjects and topics performed best. Managers receive a short written summary they can share at weekly review meetings.
Segmenting contacts for events
A membership organisation can ask Claude to group contacts by region, interest or event attendance. Claude creates the relevant lists in Laposta so invitations reach the right people. Staff keep control of the criteria and check the final groups before anything is sent.
Responding to sign-up questions
When new subscribers have questions about joining or updating their details, Claude can look up their record and explain the options. Staff handle any requests that involve data changes beyond the agreed scope, keeping personal information under human supervision.
An end-to-end workflow: Event invitation with CRM follow-up
TriggerA new event is added to the events calendar in Microsoft 365 or the organisation's CRM.
Claude reads the event details and identifies contacts in the CRM who have registered interest in that topic.
Claude creates a targeted subscriber segment in Laposta and drafts an invitation newsletter.
The events lead reviews the draft and the segment, then approves the send.
Claude sends the campaign through Laposta and records the send date in the CRM.
After the campaign closes, Claude pulls the response figures and adds a summary to the CRM record for each campaign contact.
The team reviews non-responders and decides on a follow-up.
OutcomeInvitations reach the right audience with less manual work, and every campaign is linked back to the CRM. Typical results are faster event promotion and clearer follow-up records, though outcomes vary by organisation.
How we set it up
Free automation audit
We review how your team currently creates, sends and reports on newsletters, and identify the workflows worth automating first. You receive a clear plan with no obligation.
Secure connection
We connect Claude to your Laposta account using an API key, which we store securely and scope to the permissions each task needs. Where a direct API is more suitable, we use that instead.
Workflow design
We design the end-to-end process across Laposta and your other systems, such as Microsoft 365 or your CRM. We agree exactly which actions Claude may take alone and which need human approval.
Testing with real cases
We test the workflow against past campaigns and real subscriber lists, checking accuracy and tone. Any issues are fixed before anything goes live.
Launch and team training
We launch with monitoring and audit logs in place, then train your team on how to give requests, review drafts and approve actions. Support continues during the first weeks of use.

For teams in the US, UK, India and the Middle East
Organisations in the United States and the United Kingdom can use this connection with their existing data protection arrangements in place. Businesses in India must meet the Digital Personal Data Protection Act, 2023, and we design consent and data handling around it. Companies in the UAE and Saudi Arabia are subject to their national data protection laws, which we account for in the design. We can host the Claude application in India, the United States, the United Kingdom or the European Union to meet your requirements.

Frequently asked questions
What does the Laposta MCP server do?
The Laposta MCP server acts as a secure bridge between Claude and your Laposta account. It allows Claude to read subscriber lists, view campaign reports, organise contacts and, where permitted, prepare and send campaigns. It lets you manage the newsletter platform through natural language instead of navigating every screen manually.
Is connecting Claude to Laposta secure?
Security depends on how the connection is set up. We use an API key scoped to the permissions each task needs, store it securely, and limit what Claude can do. Sensitive actions such as sending campaigns can require human approval, and all activity is logged for review.
What can Claude actually do in Laposta?
Typically Claude can look up subscribers, group contacts into lists, summarise campaign results, draft newsletter content and help prepare sends. The exact capabilities depend on the access granted and the workflow designed. Your team decides which actions are automatic and which require approval.
How long does setup take?
Many straightforward connections can be set up and tested within a few weeks, following the free audit. Larger or multi-system workflows, such as those linking Laposta to a CRM, usually take longer. We confirm a realistic timeline during the audit.
Which plan or permissions do I need?
You need a Laposta account with API access and an API key that you generate from your account settings. The permissions attached to that key determine what Claude can do. Plan requirements vary, so we check your current arrangement during the audit.
