HubSpot AI Marketing Email Tool Review: Does It Actually Help?

HubSpot keeps expanding its lineup of AI tools, and while many are impressively helpful, it can still be tricky to figure out which ones fit into your day-to-day workflow, especially when you’re already juggling 37 open tabs and running on your third latte.

In this post, we’re testing HubSpot’s AI Marketing Email Tool to see what it does, how well it works and whether it’s something marketers (or agencies like ours) should rely on.

Where to Find It

This tool lives right inside HubSpot’s familiar ecosystem. You’ll find it under:
Marketing > Email > Create Email

It’s built directly into the email editor, so there’s no hopping between platforms or exporting drafts, keeping everything neatly inside HubSpot.

What It Does

The AI Marketing Email Tool is designed to help you write marketing emails faster. It can draft subject lines, preview text, body copy and even help tweak your CTA language.

It’s supposed to:

• Break writer’s block
• Provide first drafts you can edit to match your voice
• Speed up ideation by giving you multiple takes on the same topic

It also allows you to select a tone, adjust the length and regenerate as many times as you want.

How It Works

Here’s the quick step-by-step:

1. Start a new marketing email in HubSpot, then click the “Collaborate with Copilot” prompt in the editor.

2. You’ll be asked what your email is about. This can be as simple as:

• “Announce a new product launch”
• “Promote our digital marketing services to small business owners”

3. Pick a tone (friendly, persuasive, formal, etc.) and desired length (short, medium, long).

4. The tool will generate a draft right inside your email editor. You can immediately tweak, regenerate or accept it.

5. Add personalization tokens, adjust formatting and review it like you would any normal marketing email.

Tips for Better Results

• Be specific with your prompt. The more details you give (about your offer, audience or vibe), the better the output.
• Try different tones. We found “friendly” or “conversational” worked best for sounding like us. We were even able to feed in a sample of our brand voice for the AI to emulate.
• Always human-check. It’s a great head start but still needs your brand personality layered on top.

Putting It to the Test

What We Tested

We decided to use the AI to draft an email that introduces Antidote 71 and our services, aimed at potential clients who might be curious about what we do.

Why?

Because writing your own about-you pitch is notoriously hard (ironic, right?). It was the perfect way to see if HubSpot’s AI could capture our voice–energetic, honest and a little cheeky.

Our Setup

• We used the prompt: “Introduce Antidote 71 marketing agency services to potential clients in a friendly, creative tone.”
• We decided not to upload documents initially, relying on our prompt plus selecting “friendly” and “medium” length.

What We Got

The AI spit out a pretty decent first draft that was a bit generic (lots of “we’re passionate about helping businesses grow!”). We used it as a skeleton, then layered on our own voice.

We ended up with a final version that was shaped by the AI’s structure, but very much sounding like us. 

Final Thoughts & Recommendations

So, would we use it again? Absolutely–with caveats.

• Who should use it:
  • Marketing teams who need to get past blank page syndrome fast.
  • Small teams without copywriters will find it especially handy.
• Where it falls short:
  If you’re hoping for a polished, on-brand final draft in one click… keep hoping. It still needs your strategic brain and creative finesse.
• Our verdict:
  3.8 / 5. Great for getting unstuck and saving time, but always needs a human touch.

Quick Pros & Cons

Pros

• Speeds up first drafts
• Multiple tone and length options
• Built right into HubSpot emails

Cons

• It can sound generic at first
• Needs heavy editing for voice
• Doesn’t magically know your brand

Bottom Line

HubSpot’s AI Marketing Email Tool is like having a junior copywriter who’s super fast–but still needs your direction. It helped us focus less on staring at a blinking cursor and more on shaping the story we wanted to tell.

If you’re curious or drowning in too many campaigns to write by hand, give it a spin. Just promise you’ll still let your brand’s personality shine through.
