If writing HubSpot emails is taking more time than the campaign itself, you’re not alone. Marketers like you often lose hours drafting and editing content, only to hit delays in tone approvals, compliance reviews, or last-minute edits. Even with a well-oiled automation setup, it’s often the content stage that grinds things to a halt.
You might have automation flows ready, segmentations dialed in, and goals lined up. But then email copy becomes the bottleneck—especially when crafting personalized content across multiple segments. Templates help, sure, but don’t erase the manual lift of writing unique, brand-consistent messages.
Here’s how HubSpot’s built-in AI capabilities can change that. This guide walks you through how AI-generated emails in HubSpot work, how to implement them in your current setup, and how to avoid common pitfalls. You’ll leave with a step-by-step workflow and a framework for measuring performance, so you can move fast—without cutting corners.
Create High Impact HubSpot Emails in Seconds with AI
Inside HubSpot Marketing Hub, you’ll find an integrated AI writing tool designed to simplify how you develop and customize email content. Rather than starting from scratch every time, you can feed prompts and settings into the built-in AI assistant, which draws from your CRM data and marketing goals to suggest well-structured, brand-relevant email copy.
You access this tool directly from the email editor. Whether you’re drafting a new campaign or editing an existing one, you can tap the AI assistant to generate subject lines, body content, and CTAs. Just provide a clear prompt (like your offer or audience), choose a tone, and the assistant takes care of the rest—right inside your draft.
This eliminates the need to switch tabs or paste in outside content. Everything stays within your HubSpot environment, including formatting, personalization tokens, and contact logic tied to workflows. The result: higher-quality emails delivered faster, all without losing alignment with your brand voice.
How It Works Under the Hood
HubSpot’s AI email tool doesn’t just pop out generic text—it uses large-language models in the background to generate content that fits your strategy. You stay in control by inputting the creative direction. The tech handles the structure and phrasing.
Here’s the type of input you give the tool:
- Prompt: What the email’s about, who it targets, or what stage of a campaign it supports.
- Tone: Choose from styles like professional, conversational, or concise.
- Context: Optional product details, customer segment insights, or offer benefits.
Once entered, the AI generates subject lines and full-body content. You can click to rephrase, shorten, or expand until the tone feels right. It preserves your personalization tokens and formatting, enabling immediate editing without losing field logic or segmentation.
Unlike external AI tools, this lives inside your secure HubSpot account. That means your outputs stay connected to your workflow triggers, contact lists, and campaign metrics. You still own the editing and brand checks—but the time-consuming first draft gets done in seconds.
Main Uses Inside HubSpot
Email Campaign Drafting
Campaigns demand timely copy, but it’s tough to balance that speed with brand quality. With HubSpot’s AI, you create strong drafts right inside your workflow.
Example: Say you’re announcing a new feature that simplifies social media scheduling. Enter a prompt like “Introduce our new one-click scheduler to help teams save time.” The AI gives you a complete draft including a headline, body, and CTA. You tweak the message for specificity, drop in a personalized [First Name] token, and finalize the email in one editing session—rather than four rounds of internal review.
Lead Nurturing Sequences
When building nurturing workflows, the volume of messages can add up quickly. AI helps you shift from writing to refining.
Example: You’re creating a three-part onboarding series for free trial users. Ask AI to generate follow-up messages centered on support access, product benefits, and upgrade paths. The tone stays consistent across all emails, and you still tailor messages to lifecycle stages or behavior triggers before launch.
Internal Notification and Sales Follow-Ups
Not just for prospecting—AI writing tools also help other teams streamline internal messaging.
Example: Your RevOps team wants to alert reps when a lead turns sales-qualified. Instead of drafting from scratch, use AI to suggest a clean internal email summarizing customer activity and action steps. The content stays in-platform, auto-populates CRM fields, and helps your sales team act faster.
Common Setup Errors and Wrong Assumptions
- Skipping the review step: AI writing speeds up drafting, but doesn’t replace your judgment. Review for tone, correctness, and compliance with your brand guidelines every time.
- Using vague prompts: A prompt like “write an email about our product” forces the AI to guess. Instead, give it direction like, “Describe how Feature X helps marketing teams cut publishing time by 50%.” Precision = better results.
- Forgetting personalization fields: The AI won’t automatically include HubSpot tokens like [First Name] or [Company Name]. You’ll need to insert those manually using HubSpot’s personalization tools.
- Ignoring contact segmentation: AI doesn’t adjust for audience nuance unless you provide it. Match each message to an accurate list and lifecycle stage, or the copy—even if well-written—won’t land where it matters.
Step-by-Step Setup or Use Guide
To get started, make sure you have Marketing Hub Professional or Enterprise access and that the AI Assistant is enabled in your HubSpot instance.
- Go to Marketing > Email
This is your central hub for building or managing marketing emails.
- Select “Create Email” and choose the email type
Pick ’Regular’ for one-time sends, or ’Automated’ if the email is part of a workflow.
- Choose a layout template
Your layout controls where your copy, images, and CTAs will go—choose one that fits your message type.
- Inside a text block, click the AI Assistant icon
This opens the native AI writing panel right where your content will live.
- Write a clear prompt and pick a tone
For example, “Announce new pricing for small businesses. Tone: friendly.” The more specifics you give, the better.
- Review what the AI produces
Rephrase, shorten, or adjust until it meets your standard. Let the tool get you 80% there, then take it across the finish line.
- Add personalization tokens
Use the token selector to customize sections like greetings or company name fields to match your contact’s records.
- Save the draft and send a test
Always test for rendering problems and confirm your links, personalization, and tone work across inboxes.
Measuring Results in HubSpot
Once your AI emails are live, tracking their performance is the only way to improve them. HubSpot provides robust reporting tools that help you pinpoint strengths and gaps over time.
Key metrics to monitor:
- Open rates: A quick pulse check on whether your subject line made an impact.
- Click-through rates: Measure how compelling your call to action and core message are.
- Reply or conversion rates: Tie email engagement directly to leads, sales, or user behaviors.
- Delivery rates: Verifies your contact lists are healthy and emails are landing where they should.
Performance tracking checklist:
- After launch, use the “Performance” tab in your email dashboard to review initial data.
- Benchmark AI-written emails against your manually crafted ones to weigh performance differences.
- Add custom KPI dashboards—like emails influencing deals or form submissions—to track effectiveness across the campaign.
- Filter by naming conventions (e.g., emails tagged with ’AI’) to isolate qualitative trends and inform future campaigns.
This feedback loop is gold. The more you measure, the stronger and more targeted your AI prompts get over time.
Short Example That Ties It Together
Let’s say your team just rolled out a new onboarding flow. You head into HubSpot, select “Create Email,” and opt for a simple template. In the main text area, you open the AI Assistant and prompt: “Write a welcome email for new customers showing how to access their dashboard and set up a training session. Tone: friendly.”
Within seconds, you get a draft complete with a greeting, guidance, and a CTA. You fine-tune a few lines, drop in a [First Name] personalization token, and link the button to your booking page. Then you plug the email into your welcome workflow and hit schedule.
After sending, you track clicks on the booking link using HubSpot’s reporting tab. You notice a higher response compared to your older manual emails—and the best part? It only took you ten minutes to write, test, and schedule.
