How to Leverage HubSpot Campaign Assistant

AI has become a core element of modern martech, with nearly all major ESPs integrating it into their platforms. Whether it’s Salesforce’s Agentforce, Braze AI, or HubSpot’s Breeze, artificial intelligence is now embedded across the ecosystem.

In today’s post, we discuss HubSpot Campaign Assistant, which is an AI-powered tool designed to help marketers quickly and efficiently create marketing assets for their campaigns. It acts as a writing assistant that generates initial drafts of content. 

At Mavlers, where our team runs over 70 HubSpot campaigns and automations every month, AI has become second nature. And on the surface, AI may seem easy to use. Strike that. It is!

HOWEVER, while AI is efficient, it doesn’t reward ambition alone. That’s why, even with HubSpot’s powerful time-saving AI tools, our team remains deeply involved in supporting 150+ HubSpot clients. Because while AI looks easy, it’s deceptively “unsimple.” 

If you’ve been wrestling with HubSpot’s AI marketing assistant, this guide is for you. Let’s begin!

Benefits of Campaign Assistant in HubSpot 

The core benefits of HubSpot’s AI marketing campaign generator are these: 

• It expedites content creation. Utilize it to quickly generate first drafts for various marketing assets like landing pages, marketing emails, and ad copy (Google Search Ads, Facebook Ads, LinkedIn Ads), saving significant time in the initial creation phase.
  
• Use it as an idea generator to spark creativity and provide fresh perspectives when you’re struggling to start or refine your content.
  
• Benefit from direct integration with your HubSpot account, allowing you to effortlessly transfer generated content into your HubSpot environment for further refinement and launch.
  
• Refine your copy by adjusting prompts and regenerating content until it meets your exact requirements, enabling you to fine-tune messages for optimal impact.
  
• For organizations with limited resources, it acts as a force multiplier, enabling you to produce a greater volume of high-quality content with minimal effort.
  
• All of HubSpot Campaign Assistant features are free and available in all plans. 

But before you learn how to leverage it, you need to understand what goes on behind an AI marketing assistant. 

Behind the man-to-bot handoff

The harder it is to get things done by people, the easier it is to get them done by bots. And that’s the tempting part.

Because outsourcing to bots is absurdly easy. 

And, for better or worse, the human-to-bot handoff is even more absurdly easy to scale. 

HubSpot Campaign Assistant, like most ESP’s AI-assisted campaign creators, follows a questionnaire format. Marketers simply feed in instructions and hit generate. The result? Outputs that are technically correct, but creatively hollow. And since editing feels like extra work of course, they settle for the first draft. 

The outcome? Bland emails, dull landing pages, forgettable ads.

Here’s the thing: AI has killed the first draft as we know it. Today, the first draft is error-free. And it takes substantial creative intelligence to polish that which is error-free, if not perfect.

So the real question isn’t Are you using AI in HubSpot? 

It’s Who’s using it?

The point is, you still rely on your core creative team to create your marketing assets. Let’s appreciate what “assets” truly mean. 

To help with that, we’re sharing practical tips for two assets you can build with Campaign Assistant: Landing page and email. 

(For ad campaigns, you can read the HubSpot Campaign Assistant guide on the platform’s Knowledge Base.) 

1. Landing Page

Crafting effective prompts for HubSpot’s Campaign Assistant is key to getting the best results for your landing page content. Think of it like giving clear instructions to a human copywriter – the more specific and detailed you are, the better the output.

Here’s how to feed the best prompts for each question. 

a. What is your Landing Page about?

This is your core topic and the essence of your offer. Therefore, be clear, concise, and use keywords. Good prompts include:

• “A free webinar on ‘Mastering SEO for Small Businesses’ on June 13th, 2025, at 3 PM IST.”
  
• “An exclusive offer for 20% off our Premium CRM Software for new customers.”
  
• “A downloadable e-book: ‘The Ultimate Guide to Inbound Marketing in 2025’.”
  
• “Sign-up for a free 15-minute consultation with our digital marketing experts to discuss content strategy.”

Avoid vague statements like “My business” or “Our services.” Don’t use too much jargon without context. 

And don’t cram multiple, unrelated topics into one prompt. 

b. What do you want your audience to know about?

Now this is where you highlight the key benefits, features, and value proposition. Think about your audience’s pain points and how your offer solves them. Provide 2-3 distinct points.

• “Learn practical strategies to rank higher on Google without paid ads.”
  
• “Streamline your sales process and improve customer relationships.”
  
• “Actionable tips for generating more leads and increasing conversions.”

Avoid listing features without adding benefits. And also, remember to differentiate your offer. 

c. What do you want your audience to do?

This is the specific action you want visitors to take. Make it clear, compelling, and benefit-oriented. Like these:

• “Register for the free webinar now.”
• “Claim your 20% discount today.”
• “Download the e-book instantly.”
• “Book your free consultation.”
• “Get access to exclusive content.”

The key takeaway is that you must match the CTA to your offer. Try to avoid HubSpot’s default options and create a custom CTA. 

d. Writing style 

Be careful here. HubSpot offers several writing styles that can be combined to generate the first draft. However, don’t depend on them to echo or replicate your brand voice. Because there’s a subtle difference between brand voice and brand tone. 

Brand voice is what you say, whereas brand tone is how you say it, according to Selah Creative Co. 

And no AI marketing campaign generator gets this. 

So, this is where creativity becomes indispensable. HubSpot’s first draft may reflect the chosen writing style, but it doesn’t capture the nuances of your brand’s voice and tone.

Sometimes, it doesn’t reflect the chosen style, either. 

For example, Professional + Friendly+ Informative (up to 3 options are allowed) generated this. 

But, on replacing Informative with Humorous, the output didn’t look any different. Check it out. 

The CTA button is also not the one we provided. 

So you’ve got work cut out for you. This isn’t to denigrate HubSpot Campaign Assistant. It does give you a strong head start. 

And broadly speaking, an AI marketing assistant is welcome. 

HubSpot’s AI copy generator is based on LLMs.

But current large language models (LLMs) are far from perfect. They generate content based on patterns in the data they were trained on, not on genuine understanding. This means they can confidently produce information that sounds plausible but is factually incorrect or misleading. They struggle with nuance, often miss context, and can reinforce biases present in their training data. While they’re powerful tools for generating drafts, ideas, and summaries, they still require human oversight, editing, and judgment.

2. Marketing Email

To create the best Marketing Email with HubSpot’s AI marketing campaign generator, here’s how to feed the right prompts.

a. What is your Marketing Email about?

State the primary purpose or topic of the email immediately. Is it a product launch, a new feature announcement, a special discount, an event invitation, or a newsletter? Think of this as the elevator pitch for your email. Instead of “An email,” say “Promoting our new online course on digital marketing for beginners.”:

• “Announcing a 20% off sale on all summer apparel.”
  
• “Introducing our new CRM integration for data syncing.”
  
• “Inviting subscribers to our upcoming webinar on SEO best practices.”
  
• “Monthly newsletter highlighting recent blog posts and company news.”

Use specific terms related to your product, service, or event that you want the AI to incorporate.

b. What do you want your audience to know about?

Focus on what your audience is set to gain. If there are discounts, deadlines, unique features, or important dates, include them here. The more specific, the better. Example prompts:

• “Our new CRM integration allows for automatic lead scoring and direct Salesforce sync, saving sales teams hours each week.”
  
• “Latest blog posts on content marketing trends and remote work tips. Plus, an exclusive sneak peek at our upcoming product roadmap. Learn more about our company culture.”
  
• “Learn advanced keyword research 7 content optimization strategies. Our expert speaker will share actionable tips. The webinar is free, happening July 15th at 2 PM EST.”

Here’s the marketing email Campaign Assistant generated. And for  writing style, we combined Helpful + Positive + Confident.  

It’s flawed. The text is too long. And the heading is dull. But it does furnish your mind with the right pointers. Once you hand it off to an email copywriter and designer, you’ll notice the change. 

It will be more striking than the difference between the two. 😊

Wrapping up!

HubSpot Campaign Assistant is a powerful springboard, not the final leap. It accelerates the content creation process, yet still depends on the marketer’s clarity, creativity, and contextual intelligence. The truth is, AI doesn’t reduce your effort; it redirects it. Instead of starting from scratch, you’re now refining and elevating.

So don’t use Campaign Assistant to replace your creative process; use it to amplify it. The better your prompts, the better your outputs. But the best results? They still come from a thoughtful human touch layered on top of smart AI scaffolding.
