- The Claude Marketplace has over 6,000 integrations: the right choice depends on the work Claude has to do in your workflow, not on a list of the best-known names.
- HubSpot has launched an official connector that lets you read and write CRM records, analyze emails and create content directly from the Claude chat.
- Anthropic's official Marketing plugin covers 7 key tasks (content, campaigns, SEO, email, reports) and connects to HubSpot, Slack, Figma, Canva, Klaviyo and Ahrefs.
- In Italy only 15.7% of SMEs already use AI: those who start now with the right integrations have a real edge over competitors.
As of October 2026, the catalog of Claude integrations has passed 6,000 available connectors. Choosing the wrong ones means paying for a subscription to automate things that don't matter. Here's how to find your way.
Is it really worth adding Claude plugins to my marketing stack?
It depends on how many hours per week your team spends on repeatable tasks like content drafts, reports and campaign planning. If the answer is 'a lot,' the right plugins win back real time.
A Claude plugin is a connector, a digital bridge that lets the AI assistant read and write data inside the tools you already use: your CRM, your email marketing tool, your content management system. Without plugins, Claude only responds to what you type in the chat. With the right plugins, Claude accesses your real data and acts directly on your systems.
The question isn't whether useful plugins exist. There are thousands. The question is: which work do you want to take off your team's plate? Start there, then choose the tool.
| Your situation | Is it worth it? | why |
|---|---|---|
| You produce content every week (blog, email, social) | Yes | Claude with a CRM or CMS plugin cuts drafting time by 60-70% (illustrative estimate) |
| You build manual campaign reports every month | Yes | The HubSpot plugin reads the data and generates the report in chat, with no manual exports |
| You manage campaigns across multiple channels (email, ads, social) | Yes | Plugins connect Claude to Klaviyo, Ahrefs, Canva and more in a single workflow |
| You have fewer than 5 people on your team and no active CRM | No, for now | Without structured data to connect, plugins add complexity without value |
| You already use HubSpot or Salesforce with up-to-date data | Yes | The official connector is already available and ready to use |
What really happened: how has the Claude plugin ecosystem grown?
In less than a year, the Claude integration catalog has grown from about 50 connectors to over 6,000. Growth has been so fast that today the problem isn't finding a plugin, but choosing the right one.
At the start of 2026, the official Claude connector directory listed about 50 integrations. By June 2026 there were already 369, spread across 11 categories. By October 2026, according to data gathered by the community on GitHub, the total catalog had passed 6,368 MCP integrations (Model Context Protocol, the standard protocol that lets Claude communicate with external tools).
On September 23, 2026, Anthropic launched the Claude Marketplace, with over 2,000 connectors available at launch and partners such as Atlassian, Google, Microsoft, Notion and Salesforce, as reported by Bleeping Computer.
This ecosystem is also growing thanks to the MCP standard: according to the official Anthropic blog (July 2026), Claude already has over 950 active MCP servers, used by millions of people every day. An open standard means anyone can build a connector, and that speeds up adoption.
What are the most useful Claude plugins for marketing?
Anthropic's official Marketing plugin and the HubSpot connector are the most solid starting points. They cover most of a marketing team's workflows without requiring complex setup.
The official Anthropic Marketing plugin (version 1.2.0, updated in June 2026) includes 7 slash commands, quick instructions you type in the chat to start a specific action. You'll find them in the ClaudePluginHub directory.
| Slash command | What it does | Connects to |
|---|---|---|
| /draft-content | Generates drafts of articles, posts and copy | HubSpot, Canva, Figma |
| /campaign-plan | Plans a campaign with goals and channels | HubSpot, Slack |
| /brand-review | Checks tone and style consistency | Figma, Canva |
| /competitive-brief | Creates a competitive brief on a market | Ahrefs |
| /performance-report | Generates a campaign performance report | HubSpot, Klaviyo |
| /seo-audit | Analyzes a page or a domain | Ahrefs |
| /email-sequence | Writes an automated email sequence | HubSpot, Klaviyo |
The HubSpot connector for Claude, released on July 29, 2025 as the first CRM with an official integration, lets you read and write CRM records, analyze email performance and create landing pages and blog posts directly from the chat. Technical details are in the official HubSpot changelog.
If you already use HubSpot, this connector is the most natural starting point: you don't have to change tools, just add Claude as an assistant inside your existing workflow.
How do marketing team workflows actually change?
With plugins active, Claude is no longer an assistant you ask questions: it becomes an operator that acts on your systems. This changes who does what, and how quickly.
- 1 · Marketing managerSets the goalWrites in chat what's needed: 'Create an email sequence for the launch of product X, professional tone, 3 emails in 7 days'.
- 2 · Claude plugin + HubSpotReads the CRM dataThe connector accesses segmented contacts, previous emails and historical performance to give the response context.
- 3 · ClaudeGenerates the draftsProduces the 3 emails with subject line, body and CTA, already formatted for import into HubSpot or Klaviyo.
- 4 · In-house copywriterReviews and approvesChecks tone, accuracy and brand consistency. Review takes far less time than writing from scratch.
- 5 · Claude plugin + KlaviyoPublishes the sequenceWith the /email-sequence command, the sequence is loaded straight into the sending platform, ready to be scheduled.
Three concrete scenarios: what changes for an e-commerce, a professional firm, and a manufacturing company?
Claude plugins fit very different contexts. What changes is the connector you activate and the type of data you connect.
The three scenarios below are illustrative: the numbers show the kind of value you can recover and are not real client data.
| Company type | Automated workflow | Plugins used | Estimated value (illustrative) |
|---|---|---|---|
| E-commerce (fashion, 10 people) | Post-purchase email sequences + monthly campaign report | HubSpot + Klaviyo + /performance-report | 4-6 hours/week saved for the team |
| Professional firm (consulting, 5 people) | Blog article drafts + monthly SEO audit | /draft-content + /seo-audit + Ahrefs | 2-3 hours/week saved for the marketing manager |
| Manufacturing company (B2B, 50 people) | Competitive briefs for the sales area + LinkedIn campaign reports | /competitive-brief + /performance-report + HubSpot | 50% reduction in brief preparation time |
How do the available tools and plugins compare?
Beyond the official Anthropic plugin and the HubSpot connector, there are integrations for every stack. The right choice depends on the tools you already use.
| Plugin / Connector | Ideal for | Connects to | Available on |
|---|---|---|---|
| Anthropic Marketing plugin v1.2.0 | Marketing teams with a mixed stack | HubSpot, Slack, Figma, Canva, Klaviyo, Ahrefs | Claude Marketplace |
| Official HubSpot Connector | Teams using HubSpot as their main CRM | HubSpot CRM, email, landing pages | Claude Marketplace / HubSpot App Marketplace |
| Salesforce Connector | Mid-market companies using Salesforce | Salesforce CRM, campaigns, leads | Claude Marketplace |
| Notion Connector | Teams managing content in Notion | Notion workspace, databases, pages | Claude Marketplace |
| Atlassian Connector | Teams using Jira and Confluence | Jira, Confluence, project management | Claude Marketplace |
| Google Workspace Connector | Anyone working in Google Docs, Sheets, Gmail | Google Docs, Sheets, Gmail, Calendar | Claude Marketplace |
What risks and rules should I consider before enabling plugins?
Plugins give Claude access to your business data. Before you activate them, you need to understand what is read, what is written and where the data goes.
When you activate a connector, Claude can read CRM records, campaign data and company content. That's the value, but it's also the risk if access isn't configured correctly.
Three questions to ask before enabling any plugin:
- What data does the connector read? Check the permissions requested during installation. A plugin that asks for access to all your CRM contacts when you only need it for reports is an unnecessary risk.
- Does the data leave the EU? Check the terms of Anthropic and the connector provider for GDPR compliance (the European regulation on personal data protection).
- Who on the team can use the plugin? Define roles and access before rolling out the tool. Not everyone should be able to write records to the CRM via Claude.
To learn more about handling business data with AI tools, the article on ChatGPT and business data offers a practical overview of human review and governance.
| Risk | Probability | How to mitigate |
|---|---|---|
| Excessive access to CRM data | Medium | Set the minimum permissions necessary for each connector |
| Personal data outside the EU | Medium | Check the DPA (data processing agreement) with Anthropic and providers |
| Errors in automatically published drafts | High | Always keep a human review step before publishing |
| Dependence on a single AI provider | Low | Use connectors built on open standards (MCP) so you can switch tools |
| Uncontrolled costs from heavy use | Medium | Set monthly usage limits and monitor token consumption |
Why it's being talked about now: is the AI market in Italy really ready?
The Italian AI market reached €1.8 billion in 2025, but only 15.7% of SMEs already use AI tools. If you start now with the right integrations, you gain a real advantage.
According to the Artificial Intelligence Observatory of Politecnico di Milano, the Italian AI market reached €1.8 billion in 2025, up 50% from the previous year. 46% of the market is already generated by generative AI solutions or hybrid projects.
The most relevant figure for anyone deciding today comes from the analysis of ISTAT data (ICT, December 2025): only 15.7% of Italian SMEs use AI, versus 53.1% of large companies. A gap of 37 percentage points that represents a concrete opportunity for those who move now.
On the CRM front, the foundation most marketing plugins rely on, Eurostat data cited by BlazehIve (May 2026) shows that only 28.5% of EU companies use CRM software. Large companies are 2.6 times more likely than small ones to have one in place.
This context explains why tools like Claude Skills, described in the article on Claude Skills and automating repetitive workflows, are becoming relevant for Italian SMEs too, not just large companies.
How do you get started: the steps to enable Claude plugins in marketing
Start with the task that costs your team the most time, not the most famous plugin. Then add one connector at a time, measure and expand.
- 1 · Marketing managerIdentify the most time-consuming workflowPick just one task: monthly report, content drafts or email sequences. Start there, not with everything at once.
- 2 · IT / Digital leadCheck permissions and GDPRBefore installing any connector, check what it reads and what it writes. Set the minimum permissions necessary.
- 3 · Marketing teamEnable the connector and test it on real dataUse the Claude Marketplace to install the plugin. Test it on a real but non-critical project (e.g. an internal newsletter).
- 4 · Marketing managerMeasure the time saved in the first 4 weeksCompare the time spent before and after. If there's no measurable improvement, the problem is in the setup, not the tool.
- 5 · Marketing team + ITExpand to other connectors only after the first successAdd a second plugin only when the first one works well. Avoid enabling everything at once: it adds complexity without adding value.
What mistakes are most common when integrating AI plugins into marketing?
The most common mistake is activating many plugins at once without a clear process. The second is using Claude to publish content without human review.
Anyone working on AI and process automation sees the same patterns again and again. Here they are, in order of frequency:
- Enabling too many plugins at once. Every connector adds complexity. Start with one, learn how it works, then expand.
- Not defining who reviews the output. Claude generates drafts, not publication-ready content. You always need a human step before publishing.
- Connecting Claude to outdated data. If your CRM has old or incomplete records, Claude produces output based on wrong data. AI quality depends on data quality.
- Ignoring usage costs. Plugins that make many API calls (automatic requests to the system) can generate significant costs if you don't set limits.
- Not training the team. A plugin that isn't used properly is a waste. Dedicate at least one training session before launch.

How do I know if Claude plugins are really improving my marketing?
Three indicators are enough to tell whether the integration works: time saved, output quality and review rate. If your team corrects everything, the plugin isn't doing its job.
| Indicator | How it is measured | Alert threshold |
|---|---|---|
| Average time to produce a draft | Hours/week before vs after enabling the plugin | If it doesn't drop by at least 30%, review your setup |
| Heavy revision rate | % of Claude drafts that require a complete rewrite | Above 40% means the prompt or the input data is wrong |
| Errors in CRM data written by Claude | Number of incorrect or incomplete records created via connector | Even a single error on critical data calls for a process review |
| Cost per piece of content produced | Subscription cost + team time / number of pieces published | Compare with the pre-plugin cost to verify ROI |
| Team satisfaction | Monthly internal survey (1-5 scale) | Below 3/5 means the tool creates more work than it removes |

Is it worth integrating Claude plugins for your company?
It's worth it if you already have an active CRM (HubSpot, Salesforce or similar) with up-to-date data, you produce content or reports every week and you have at least one person on the team who can manage setup and output review.
Somewhere in between: you're considering adopting a CRM or you're structuring your content marketing process. In that case, start with the process, then add the plugin once your data is ready.
Not yet if you don't have an active CRM yet, your team doesn't have time to set up and review AI outputs, or you produce content only sporadically. Plugins would add complexity without real value.
How we see it at SHM
For us, AI in marketing workflows only makes sense when it frees people from routine work, not when it adds a tech layer on top of a process that's already messy. Claude plugins are powerful tools, but their value depends entirely on the quality of the data you feed them and on how clearly you've defined the process you want to automate.
We've worked with companies that had complex marketing stacks and fragmented CRM data. In those cases, the first step wasn't turning on a plugin. It was cleaning up the data and defining who does what. Only then did automation deliver measurable results.
If you're evaluating how to integrate Claude or other AI tools into your marketing stack, start by figuring out which workflows really eat up your team's time. From there, you build an integration that lasts, not a demo that impresses for a week.

Frequently Asked Questions
Yes, Claude Marketplace plugins and connectors require a Claude Pro or Team plan (or higher). The free plan doesn't support integrations with external tools like HubSpot or Klaviyo. Check the latest plans on claude.ai before you proceed.
The official HubSpot connector uses HubSpot's standard APIs with OAuth authentication, the same system used by all apps in the HubSpot marketplace. Before enabling it, review Anthropic's data processing terms for GDPR compliance, especially if you have customers in the European Union.
Yes. Anthropic's official Marketing plugin also connects to Slack, Figma, Canva, Klaviyo and Ahrefs, independent of HubSpot. If you use Salesforce, Notion or Google Workspace, there are dedicated connectors in the Claude Marketplace. The right choice depends on the tools your team already uses.
For official connectors like HubSpot or Notion, the basic setup takes 30-60 minutes, including authentication and the initial test. The longest part is setting the right permissions and running the first tests on real data. Plan on half a day for the first activation, including team training.
Technically yes, if you set up the connector with write permissions and skip an approval step. But we don't recommend it: Claude can make factual or tone errors that always need human review before publication. Always set up a workflow with manual approval for public content.
No. Data written to your CRM through the Claude connector (records, emails, landing pages) stays in the CRM regardless of your Claude plan. The connector is a means of access, not an archive. If you cancel your plan, you only lose the ability to use Claude to write new data, not the data already created.
The real competitive advantage isn't having the most powerful plugin: it's knowing exactly what job you want it to do for you.
