Get Started with Sendblox See How It Works
Stop navigating dashboards. Start talking to your campaigns.
What if your AI assistant could actually do the work?
The assistant already writes the campaign. Without MCP that work stops at copy and paste. With Sendblox MCP the same conversation reaches the campaign tools you authorised.
Without MCP: You write with the assistant, then copy the draft, paste it into your marketing software, and set the audience and sequence up yourself.
With Sendblox MCP: You say what you want. The assistant talks to Sendblox. A draft is prepared in your account. Review still sits before send.
What an assistant can do in Sendblox
Creating a campaign does not send it. Launch needs the right permissions and readiness checks. Some operations are irreversible. The connector does not expose a general-purpose reply-sending tool.

How do I connect Sendblox MCP?
- Create a connection in Sendblox: As an organisation admin on Growth or Scale, open Account settings, then MCP. Create a connection and copy the token. The key is shown once. Do this before you touch the assistant.
- Add Sendblox in your assistant: Look for a Sendblox plugin or connector in the chat agent you already use.
If Sendblox is listed: Click Add and authenticate with the connection you just created.
If it is not: Give your assistant the setup snippet from Sendblox. If that agent supports MCP, it will create the direct connection.
- Ask it to work: Describe the campaign, sequence or review in ordinary language. Sendblox runs only the tools that key allows. Launch, send and approval stay behind those permissions.
How to connect
- In Sendblox, open Account settings → MCP and create a connection. Copy the token. It is shown once.
- In your chat agent, look for a Sendblox plugin or connector.
- If Sendblox is listed, click Add and authenticate.
- If it is not listed, give the assistant the setup snippet from Sendblox. If that agent supports MCP, it will create the direct connection.
- The customer endpoint is https://www.sendblox.io/mcp. Revoke the key in Sendblox if it is lost or no longer needed.
Who is Sendblox MCP for?
Small business owners, sales teams, marketing teams, marketing agencies, recruiters, and founders and entrepreneurs who already use AI to write or run outreach, and want that assistant to do the work in Sendblox.
Small business owners
AI marketing automation. You already use an assistant to write marketing emails. MCP lets that same chat prepare the campaign in Sendblox, so the work does not stop at copy and paste.
Sales teams
AI sales outreach automation. If the team drafts outreach in ChatGPT or Claude and then pastes it into a sequence, MCP is the missing step. The assistant talks to Sendblox. Review still sits before send.
Marketing teams
AI email campaign management. When the team already briefs campaigns in an assistant, MCP turns that brief into a draft, sequence or review inside Sendblox.
Marketing agencies
Automated client outreach. You already use AI to move faster for clients. MCP keeps that work inside the client Sendblox account you are authorised to access.
Recruiters
AI recruitment outreach. If you already write candidate or client outreach with an assistant, MCP can prepare that campaign in Sendblox. It does not replace an ATS.
Founders and entrepreneurs
AI-powered lead generation. You already use AI to write the first outreach. MCP lets that assistant open a campaign draft in Sendblox from the brief, so you are not copying the draft into another tool.
Sendblox is the outreach execution platform. MCP is the connection layer. It does not replace the CRM or the assistant.
Trust, security and control
Connections are created by an organisation admin and stay inside that account. Each key has explicit scopes. Launch, send and review approval are optional. Consequential tools are audited. Contact lists are bounded. Secrets and provider credentials are never returned. Revoke a key in Sendblox at any time.
What does Sendblox MCP cost?
Sendblox MCP is included on Growth (£499 a month) and Scale (£999 a month). It is not included on Free or Starter. Enterprise can include it when Sendblox enables it on that organisation. See Sendblox pricing.
Frequently asked questions
What is Sendblox MCP?
Sendblox MCP is the Model Context Protocol connection for the Sendblox app. A compatible AI assistant can call authorised campaign tools in your account: create drafts, manage sequences, read analytics, and work the review queue. It is not a chatbot bolted onto a dashboard, and it is not the website MCP used to draft marketing pages.
How does Sendblox MCP work?
You create a connection in Sendblox Account settings, on Growth or Scale, as an organisation admin. Your assistant sends signed requests to the customer MCP endpoint. Each tool runs with the scopes on that connection, inside your organisation, and writes an audit record.
What can an AI assistant do with Sendblox?
The connected Sendblox MCP can create and manage campaigns, build or import audiences, create sequences, generate campaign copy, preview personalised messages, work the review queue, read stored performance and replies, list senders and integrations, check usage, and watch background jobs. Creating a campaign does not send it. Launch needs the right permissions and readiness checks. There is no general-purpose reply-sending tool.
Can I use MCP to manage email campaigns?
Yes. Campaign in this context is an outbound email campaign on sendblox.io, not a web page. Create stays in draft or hold. Launch is a separate, permissioned step that re-runs preflight.
Does Sendblox MCP replace my CRM?
No. Sendblox remains the outreach execution platform. The CRM stays the source of your contacts. MCP is the connection layer between a compatible assistant and Sendblox.
Which AI assistants support Sendblox MCP?
Sendblox ships connection guides for ChatGPT, Claude, Grok and Cursor. Any other MCP-capable client can use the same Streamable HTTP customer endpoint with an Authorization header. That is a documented connection method, not a partnership badge.
Is Sendblox MCP included in every plan?
No. MCP is included on the Growth plan at £499 a month and the Scale plan at £999 a month. It is not part of Free or Starter. Enterprise can include it when Sendblox enables it on that organisation.
Do I need technical experience to use it?
Create a connection and token in Sendblox Account settings first. Then look for a Sendblox plugin or connector in your assistant. If it is there, click Add and authenticate. If it is not, give the assistant the setup snippet. If that agent supports MCP, it will create the direct connection. After that, you describe the work in ordinary language.
Can I review campaigns before sending?
Yes. Creating a campaign does not send it. Launch requires campaign:launch and email:send, re-runs preflight, and manual review holds every message until it is approved. Approval of a review item marks that contact sendable; it does not send on its own.
What is the difference between MCP and traditional marketing automation?
Traditional automation runs a sequence you built in a dashboard. MCP lets a compatible assistant call the same Sendblox campaign tools through conversation, still inside your permissions, still with review before send. The assistant does not replace the CRM, and it does not bypass Sendblox.
