Unisender MCP with Claude: Automate Email and SMS Campaigns
The short answer
Claude works with Unisender through the Model Context Protocol (MCP), an open standard that lets Claude securely use software with permissions you control. Once connected with an API key, Claude can read contact lists, create segments, prepare campaigns and automate email and SMS marketing from plain-language instructions.
What is Unisender?
Unisender is a service for email and SMS marketing campaigns. It helps teams reach their audience, manage subscriber lists and automate campaign management. It is typically used by marketing teams, e-commerce businesses, small and medium enterprises and agencies that send regular messages to customers and prospects. Teams use it to keep contact data organised and to run campaigns without manual repetition.
How Claude connects to Unisender 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 use a tool such as Unisender to read information and take actions, and the organisation decides exactly what Claude is allowed to do.
Once connected, Claude can typically look up contacts, review lists, create or update segments, draft campaign content, schedule sends and check campaign results. Connections can be made through Unisender's MCP server or a direct API, using an API key for sign-in. Each request reads or changes data only within the access you grant.
Permissions and approvals keep people in charge. Access is limited to what the workflow needs, and consequential actions such as sending a campaign to a live list can require a person to review and approve first. Activity is logged so your team can see what Claude did and when.
What you can automate
Segment contacts by behaviour
A marketing manager asks Claude to group subscribers who opened the last three newsletters but have not bought in ninety days. Claude builds the segment in Unisender and reports the size, so the team can target a win-back offer without spending hours filtering spreadsheets.
Draft and schedule email campaigns
A content lead provides a product launch brief. Claude drafts subject lines and body copy in the brand voice, prepares a campaign for the right segment and schedules it for review. A person checks the content and approves the send.
Coordinate SMS reminders
An operations team running appointment-based services wants reminders sent the day before each booking. Claude reads the booking list, selects the matching contacts and prepares SMS reminders in Unisender, with consent and opt-out rules applied.
Keep contact lists clean
A data administrator asks Claude to find duplicate records, flag invalid addresses and move unsubscribed contacts out of active lists. Claude prepares the changes as a summary for approval, which helps protect sender reputation and reduce wasted sends.
Report on campaign performance
A department head asks for a weekly summary of open rates, click rates and unsubscribes across recent campaigns. Claude gathers the figures from Unisender and writes a short report with the main trends and suggested next tests.
An end-to-end workflow: Event follow-up across email, CRM and SMS
TriggerA new delegate list is exported from the events system after a trade show.
Claude reads the new delegate records and checks them against the CRM to avoid duplicates.
Claude creates a Unisender list and segments delegates by interest area and how they registered.
Claude drafts a tailored thank-you email for each segment and prepares it for the sales lead to approve.
After approval, Claude schedules the email campaign in Unisender.
Contacts who open the email but do not reply within three days are added to an SMS follow-up segment, which Claude prepares for approval.
Claude logs campaign results back into the CRM so sales can see engagement.
OutcomeTypically, the team follows up with every delegate within a day, with messages matched to interest, and sales gets clearer signals on which leads are warm.

You decide which actions are allowed, and every connection runs under the access you set.
Is connecting Claude to Unisender secure?
Security depends on how the connection is set up.

We also review data handling against the privacy laws that apply to your business before launch.
What can Claude actually do with Unisender?
Typically, Claude can look up and organise contacts, create and update segments, draft email and SMS content, schedule campaigns and summarise results. The exact actions available depend on the permissions you grant and the features of your Unisender account. We confirm the scope during the audit.
How long does setup take?
Many setups take a few weeks from the free automation audit to launch, including design, testing and team training. Simpler connections can be quicker, while larger workflows across several systems take longer. We agree a timeline once we understand your lists, systems and approval needs.
Which plan or permissions do I need?
You need a Unisender account with API access enabled and an API key that your organisation is allowed to create. The permissions to set should match the workflow. Requirements vary by account, so we check your current setup during the free audit and tell you what, if anything, needs to change.
