BigMailer MCP with Claude: Run Email Campaigns and Sequences in Plain Language
The short answer
Claude works with BigMailer through the Model Context Protocol (MCP), an open standard that lets Claude securely use software with permissions you control. Once connected, Claude can help your team manage contact lists, prepare and send campaigns, automate email sequences and review performance, all through natural language instructions with human approval for key actions.
What is Bigmailer?
BigMailer is an email marketing platform built for organisations that manage several brands or business units. It offers white-labelling so each brand can present its own identity, along with automation tools for campaigns and follow-up sequences. Many teams also use it to simplify sending through Amazon SES. Marketing managers, agencies running client accounts, and e-commerce and membership teams typically use BigMailer to keep email programmes consistent and measurable.
How Claude connects to Bigmailer 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 read information from a tool and take actions in it, while the organisation decides exactly what Claude is allowed to see and do. For BigMailer, the connection is made using an API key, which is a secure credential that identifies your account.
Once connected, Claude can typically help with tasks such as looking up contact lists, summarising campaign results, drafting campaign content for a chosen brand, setting up an automated sequence or checking how a recent send performed. A marketer can ask in everyday words, for example, to compare open rates across two brands last month, and Claude retrieves that information from BigMailer.
Permissions and approvals keep people in charge. We set up least-privilege access, so Claude only reaches the lists, brands and functions your team needs. Consequential actions such as sending a campaign to a full audience are routed for human approval before they run, and every action is recorded in audit logs for review.
What you can automate
Campaign performance summaries
A marketing lead asks Claude for a weekly summary of campaign results across all brands. Claude pulls open, click and unsubscribe figures from BigMailer and presents them in a short report with notable changes highlighted, saving hours of manual reporting each week.
Contact list management
An operations coordinator asks Claude to find contacts who joined a list in the last thirty days but have never opened an email. Claude identifies them, and the team reviews the list before any clean-up action is approved and carried out, keeping sender reputation healthy.
Drafting brand-specific campaigns
A content writer provides a product update and asks Claude to draft versions tailored to each brand's tone. Claude produces the drafts for review, and the team loads the approved versions into BigMailer for scheduling, keeping each brand's voice consistent.
Onboarding sequence oversight
A customer success manager asks Claude to check how a new-user welcome sequence is performing and where recipients drop off. Claude reviews the sequence results and suggests where timing or messaging could be adjusted, for the team to decide upon.
Client account reporting for agencies
An agency account director asks Claude to prepare a monthly performance pack for each client brand. Claude gathers the relevant BigMailer data and drafts the commentary, which the director checks before sending to the client.
An end-to-end workflow: Event follow-up campaign with CRM and Microsoft 365 coordination
TriggerA sales team member logs a new event attendee list in the CRM, or a manager asks Claude to prepare a follow-up for an event.
Claude retrieves the attendee segment from the CRM and matches it against the correct BigMailer contact list for the relevant brand.
Claude drafts a follow-up email and a three-step reminder sequence, tailored to whether each attendee was a prospect or an existing customer.
The marketing lead reviews the drafts and the audience in a Microsoft 365 approval thread and requests any changes.
Once approved, Claude schedules the campaign and sequence in BigMailer and confirms the setup in the thread.
After sending, Claude posts a performance summary to the team's Microsoft 365 channel each morning for the following week.
OutcomeEvent follow-ups go out faster and more consistently, with every send approved by a person and results reported to the sales team without manual copying between systems. Typical outcomes vary by organisation.

We connect Claude to your BigMailer account using your API key, stored securely and scoped with least-privilege access so Claude only reaches the brands, lists and functions you approve.
Workflow design
We design the end-to-end process across BigMailer and your other systems, such as your CRM or Microsoft 365, and agree which actions need human approval before they run.
Testing and launch
We test the workflow against real past campaigns and sequences, then launch with monitoring and audit logs so you can see every action Claude takes.
Team training

For teams in the US, UK, India and the Middle East
Organisations in the United States and the United Kingdom can run this workflow under their own email and privacy rules, with consent and unsubscribe handling kept in place. In India, the Digital Personal Data Protection Act, 2023 governs how contact data is processed, and we design consent handling accordingly. For organisations in the UAE and Saudi Arabia, local data protection laws shape where data may be stored and processed. Claude can be hosted in India, the United States, the United Kingdom or the European Union, and we choose the hosting region to meet your requirements.

Frequently asked questions
What does the BigMailer MCP server do?
The BigMailer MCP server acts as a secure bridge between Claude and your BigMailer account. It lets Claude read information such as contact lists and campaign results, and carry out approved tasks such as preparing or scheduling campaigns. Access is defined by the permissions you set, and you can also use BigMailer's direct API where that suits your setup better.
Is connecting BigMailer to Claude secure?
Yes, when it is set up properly. The connection uses your API key, which we store securely and scope with least-privilege access. Sensitive actions require human approval, and every action is logged for review. Your administrators can rotate or revoke the key at any time to cut off access.
What can Claude actually do in BigMailer?
Typically, Claude can look up contact lists, summarise campaign and sequence performance, draft campaign content for a brand, and help set up automated sequences. The exact actions available depend on how we configure access for your organisation, and we agree those limits before launch.
How long does setup take?
Many organisations are ready within a few weeks, though timing depends on how many brands, lists and other systems are involved. The free automation audit helps us estimate the timeline, and we build in testing against real past campaigns before anything goes live.
What BigMailer plan or permissions do I need?
The connection relies on an API key, so you need an account that can generate one and permissions suited to the tasks you want Claude to perform. Requirements depend on your BigMailer setup, so we confirm them during the free audit rather than assume them.
