This post covers where to find the AI email writing tool, how to write prompts that produce usable output, what it can and cannot do, and how agencies can use it to speed up email production for clients.

Reading time: about 8 minutes.

What Is AI Email Generation in HighLevel?

AI Email Generation is a writing assistant built directly into the HighLevel Email Builder.

Instead of opening a blank text block and writing from scratch, you enter a prompt describing what the email needs to accomplish – who it is for, what it is about, what tone it should take – and the AI generates the copy inside the block.

The output is editable. You are not locked into what the AI produces.

It is a starting point that removes the blank-page problem and gets you to a working draft in under a minute.

Where to Find It

The feature lives inside the Email Builder, not in a separate menu.

Go to Marketing, then Emails, then Templates or Campaigns. Open or create an email, then click on a text content block.

The block editor opens, and in the text editing toolbar you will see an AI or magic wand icon. Clicking it opens the prompt interface.

It is available on any text block in any email – campaign emails, template emails, and potentially workflow email actions depending on your account version.

What It Can Write

The AI can write a complete email body from a single prompt, or you can use it to generate specific sections individually.

Full email body generation works best when the prompt includes enough context – audience, goal, offer, tone. A single well-crafted prompt can produce a complete draft ready for light editing.

Section-by-section generation is useful when you already have a structure in mind and want the AI to fill in specific parts. Write the intro yourself, use AI for the middle section, write the CTA yourself.

The result is a blend of your voice and AI efficiency.

Subject lines can also be generated with a targeted prompt asking for multiple options. More on that in the Subject Lines section below.

For workflows, the Send Email action inside Workflow Builder may also have AI writing assistance available – check the text editor inside the action for the AI option.

How to Write Effective Prompts

The quality of the AI output is directly proportional to the quality of the prompt. A vague prompt produces generic copy.

A specific prompt produces something close to ready-to-send.

A strong prompt includes four things: the target audience, the goal of the email, the specific offer or topic, and the desired tone.

A weak prompt: “Write a marketing email about our landscaping service.”

A strong prompt: “Write a re-engagement email for past residential landscaping customers who haven’t booked a service in 6 months. Offer a 10% spring cleanup discount.

Friendly, conversational tone. Include a clear call to action to book online.

Keep the email under 150 words.”

The second prompt gives the AI everything it needs to write something specific and actionable. The word count guidance also helps – unconstrained prompts often produce copy that is longer than necessary for email.

Other useful prompt additions: specify that no discount should be mentioned if one is not being offered, ask the AI to avoid generic phrases like “improve campaign performance,” request a specific structure (problem / solution / CTA), or ask for a particular reading level if that is relevant to the audience.

Output Quality and When to Edit

AI-generated email copy is consistently better than a blank page and rarely production-ready without some editing.

The most common issues are generic phrasing, slightly off-brand tone, and opening lines that are too formal or too casual for the specific business. A quick pass through the draft to fix these takes 2 to 5 minutes per email – still significantly faster than writing from scratch.

For agencies managing email for multiple clients, the editing pass also ensures the email sounds like the specific client’s voice rather than a generic AI template. Adding one or two client-specific details – a local reference, a service-specific term, a seasonal hook – takes the output from good to great.

If the first draft is not close enough to work with, regenerate rather than heavily rewriting. A different prompt angle often produces a better starting point than editing a poor draft extensively.

Generating Subject Lines

Subject lines are where the AI email generation feature arguably adds the most value per minute of effort.

Writing one subject line from scratch is easy. Writing five strong options to A/B test is tedious.

The AI can produce five to ten subject line variations from a single targeted prompt in seconds.

A good subject line prompt: “Write 5 subject line options for an email offering a 10% spring landscaping discount to past customers. Keep each under 50 characters.

Mix urgency, curiosity, and benefit-led options.”

Review all the options and select the one that best fits the campaign. You can also use the options as inspiration for a manually written subject line that combines the best elements of two or three AI suggestions.

What Can You Do With It?

• Draft full campaign emails from a prompt: Describe the audience, goal, offer, and tone and get a complete working draft in under 60 seconds – ready for editing rather than starting from scratch.
• Generate multiple subject line options instantly: Ask for 5 to 10 subject line variations in a single prompt and choose the strongest one – or use them as creative springboards.
• Fill in specific email sections without writing the whole thing: Use the AI to handle the body copy while you write the intro and CTA – or any other division of labor that fits your workflow.
• Speed up email production for agency clients: Draft the first version of every client email with AI, then edit for brand voice and client-specific details. The production time per email drops significantly across a high-volume campaign calendar.
• Overcome writer’s block on difficult emails: Re-engagement campaigns, apology emails, and price increase announcements are notoriously hard to start. An AI draft gives you something to react to and refine rather than a blank page staring back.
• Build nurture sequences faster: Generate drafts for each email in a sequence using prompts that specify where each email falls in the journey – introduction, nurture, offer, follow-up – and edit for consistency across the series.

Key Definitions

Use Cases by Industry

Marketing Agencies

An agency writes and sends monthly newsletters for 12 local business clients. Without AI, each newsletter requires custom copy written from scratch – 12 unique emails per month representing significant production time.

With AI Email Generation, the agency writes a specific prompt for each client’s newsletter – industry, offer, audience, tone – generates a draft, edits for brand voice and client-specific detail, and sends. The per-email production time drops from 45 minutes to 15 minutes per email.

Result: A 12-email monthly workload that previously required a full day of writing is completed in half the time – capacity that goes back into strategy and client relationship work.

Online Education

A course creator builds a 7-email welcome sequence for new enrollees. Each email needs to cover a different topic – introduction, what to expect, first lesson, community, progress check-in, halfway point, graduation prompt.

Using a separate prompt per email with context about where it falls in the sequence, the AI generates all seven drafts in one sitting. The creator edits each one for personal voice and specific course details.

The sequence is complete in a few hours rather than days.

Result: A 7-email sequence that would otherwise take 3 to 4 hours of writing is produced in under 90 minutes with AI drafts as the starting point.

Local Service Businesses

A dental practice wants to send a reactivation email to patients who haven’t visited in 18 months. The practice manager has never written a marketing email and finds the blank page intimidating.

The AI prompt: “Write a reactivation email for dental patients who haven’t booked in 18 months. Friendly, caring tone.

Mention we have new appointment availability. Include a call to action to book online.

Keep it under 120 words.”

The draft is 85% ready on first generation. Two minor edits later, the email is scheduled and sent.

Result: A non-writer produces a professional, effective reactivation email in under 10 minutes – a campaign that would otherwise not have happened at all.

E-commerce

An e-commerce brand sends a Black Friday campaign with five emails over four days. Writing five distinct emails – teaser, launch day, mid-sale, last chance, post-sale – is a significant copywriting effort compressed into a short window.

Each email is drafted using AI with a prompt specifying its role in the sequence and the urgency level appropriate for that day. The brand’s copywriter edits all five for voice consistency and brand-specific language.

The full sequence is production-ready in under two hours.

Result: A five-email campaign that would typically require a full day of copywriting is completed in a morning – with the writer spending their time on refinement rather than first drafts.

Real Estate Agencies

A real estate agent wants to stay in touch with their past clients database through a monthly market update email. They have the market data but struggle with how to frame it conversationally rather than as a data dump.

The AI prompt: “Write a friendly monthly market update email for past real estate clients. Include [market stats].

Conversational tone, like an agent who genuinely cares about their clients’ home values. End with an offer to provide a free home valuation.”

The AI frames the data into a story. The agent adds personal touches and sends.

Result: A monthly touchpoint that previously required 45 minutes of struggling with copy is completed in 15 minutes – and consistency improves because the friction is lower.

Who Is This For?

How to Use AI Email Generation

Step 1: Open the Email Builder

Go to Marketing, then Emails, then Templates or Campaigns.

Open an existing email or create a new one. Have a clear idea of what the email needs to accomplish before writing the prompt.

Step 2: Select or add a text block

Click on a text content block in the email layout.

The block editor opens with the text editing toolbar visible above the content area.

Step 3: Open the AI writing tool

Click the AI or magic wand icon in the text block toolbar.

The AI prompt interface opens.

Step 4: Write a specific prompt

Describe what you want the AI to write. Include the target audience, email goal, offer or topic, desired tone, and any specific details or constraints.

A word count suggestion helps – “keep under 150 words” prevents the AI from producing copy that is too long for an email.

Step 5: Generate the draft

Submit the prompt. The AI generates copy and inserts it into the text block.

Read the full draft before editing – sometimes the output is closer to ready than expected.

Step 6: Edit the output

Edit the generated copy in the text block. Adjust tone, add specifics the AI missed, remove generic filler, and make the email sound like the brand it is going out from.

For clients, add one or two specific details – a local reference, a service name, a seasonal element – that make the email feel personal rather than templated.

Step 7: Generate subject line options

Open the AI tool again in a separate text block or in the subject line field and use a targeted prompt: “Write 5 subject line options for this email. Keep each under 50 characters.

Mix benefit-led, curiosity, and urgency approaches.”

Review all options and add the strongest to the subject line field.

Step 8: Preview and test the email

Use the Preview function to check desktop and mobile rendering.

Send a test email to your own inbox to verify formatting, personalization tokens, and all links work correctly before the email goes to live recipients.

Step 9: Save your best prompts

After the campaign, note which prompt produced the best output.

Save the prompt structure as a text snippet or in a shared document so you or your team can reuse it with minor edits for similar campaigns in the future.

How Does It Connect to HighLevel?

• Email Campaign Automation: AI Email Generation speeds up the content creation step inside Email Campaign Automation. Write faster, test more, and send more consistently without the bottleneck of manual copywriting.
• AI Send Time Optimization: Pair AI-generated copy with AI Send Time Optimization – the AI writes the email and Smart Send delivers it to each contact at their optimal open time. Both AI features work on the same campaign.
• Workflow Builder: Email actions inside Workflow Builder can also benefit from AI-drafted copy. Write drafts in the Email Builder, refine them, and paste the finalized copy into workflow email actions for automated sequences.
• Multi-Channel Campaigns: In Multi-Channel Campaigns, use AI email generation for the email steps while writing SMS copy manually – the two channels have very different length and tone requirements that the AI handles separately.
• Database Reactivation: Re-engagement emails are among the hardest to write well. Database Reactivation campaigns benefit directly from AI generation – describe the lapsed audience, the re-engagement offer, and the desired tone, and the AI produces a strong starting draft for a campaign that most businesses put off writing indefinitely.

To Wrap It Up

The blank page problem is one of the most consistent friction points in email marketing. It is not that people do not know what they want to say – it is that starting is the hard part.

AI Email Generation removes that friction. The first draft is ready in seconds.

You react to it, refine it, and send something that sounds like your business – not a generic template, but a starting point that became a real email through your editing.

The prompting skill is worth developing. The difference between a vague prompt and a specific one is the difference between copy that needs major rework and copy that needs light polish.

Five minutes spent writing a detailed prompt saves more time on the editing side than any other practice.

For agencies, the compounding benefit is significant. Every client email that starts with an AI draft rather than a blank page reduces production time.

Across a full month’s email calendar for 10 clients, that time adds up to hours – which go back into strategy, relationship, and the work that actually differentiates an agency.

Here is how to get started:

1. Go to Marketing, then Emails, then Templates or Campaigns and open an email
2. Click a text block to open the editing toolbar
3. Click the AI or magic wand icon to open the prompt interface
4. Write a specific prompt – audience, goal, offer, tone, approximate length
5. Generate the draft and read it fully before editing
6. Edit for brand voice, client-specific detail, and any inaccuracies
7. Generate 5 subject line options with a targeted subject line prompt
8. Preview and send a test email before scheduling
9. Save your best prompt structures for reuse on similar campaigns

The AI draft is not the finished email – it is the raw material. Your editing pass is what makes it sound like the business it is coming from.

The less time you spend starting, the more time you have for that.
