Creating email campaigns can be incredibly time-consuming.

That’s especially true when you’re putting out a high volume of emails for different audiences at the same time.

Newsletters, promotional emails, and transactional emails all require different strategies when it comes to subject lines, calls to action, and visuals.

On top of that, emails may need to go through several rounds of proofing and revision before you send them out, so any opportunity to save time is critical.

AI can be a huge timesaver. In fact, 64% of content marketers already use AI regularly, while 46% of ecommerce marketers say that AI has significantly increased their productivity at work.

So, how can you leverage AI to speed up and scale your email marketing—without overloading yourself and your team?

Let’s look at 6 ways you can use AI to speed up email content creation.

1. Create talking points

Whether you’re just getting started or you’re stuck and not sure what kind of messaging to include in an email, generative AI tools like Klaviyo Email AI can get you started by providing helpful email ideas.

Enter a simple prompt like “Give me 3 benefits of sustainable fashion,” and Klaviyo Email AI will use this information to generate a list of talking points.

Be as specific as you can, here. If you want a very diverse list of contrasting ideas, be sure to include that as part of the instructions. Same thing if you want a list of talking points specific to, say, a particular holiday.

2. Write more subject lines, faster

A compelling subject line is crucial because it directly impacts whether your customers will open your email. Getting the subject line right is often one of the most intimidating and challenging steps in the email creation process.

AI can make it easier, saving you time on brainstorming and testing different options.

Klaviyo also has AI that can write subject lines based on the prompts you provide. Just choose the type of email you want to send (“Promotion” for emails announcing a sale or other special offering, “Announcement” for product launches or other big news, “Newsletter,” and so on).

Then, enter your keywords—say, a description of the product your email is promoting—and the tool will generate different subject line options to choose from in just one click.

“I love how Subject Line AI helps us analyze what subject lines have worked in the past, and gives us concise inspiration,” says Sreevats R., product manager at fresh fish retailer Svenfish. “I almost always use it to generate subject lines.”

Klaviyo’s subject line AI even adds relevant emojis automatically, which makes subject lines instantly more eye-catching in crowded inboxes.

3. Save time creating emails

AI can help you create the content within the email, too—speeding up the copywriting and layout process while giving you fresh inspiration for new ideas.

With Klaviyo Email AI, just enter a text description for the section you want the AI to generate. For example, you could input “Create an announcement for a new sweatshirt design, launching tomorrow night at 11:59 p.m,” and the AI tool will instantly generate 3 options. Want even more options? Just hit the “Generate more drafts” button.

Or, if Cyber Monday is coming up, you could say something like “Create a Cyber Monday sale reminder for 25% off with urgent messaging to order before 12 a.m. on Tuesday. Create a 2-column layout with an image at the top and a button below.”

Then, just click the “Generate drafts” button.

Klaviyo Email AI recognizes a wide variety of text inputs and generates complete email layouts with elements like text blocks (with AI-generated copy), images, spacers, and buttons. All you need to do to create an email is tell the tool what you want to see.

4. Try different styles and tones

Beyond simply writing the email for you, generative AI tools are also great at taking a headline or paragraph and writing it in different styles and tones. That makes it possible to run more experiments and test different ideas much more quickly (and with way less work) than ever before.

For example, if you want to see whether humor would resonate with your audience and increase open rates, you could use Email AI to instantly generate a funny version of a subject line and A/B test both versions to see which one performs better.

5. Personalize content to the right audience

There’s no shortage of studies and research confirming that personalization works well in marketing. But actually personalizing your emails at scale requires a lot of effort (and time).

One way to speed up this process dramatically: Klaviyo Segments AI.

With Segments AI, just describe the customers you want to reach in your email campaign and Klaviyo will build a targeted audience segment for you.

6. Send emails at the perfect time

This one isn’t so much about email content creation, but it is related to email campaign creation. AI tools can analyze your recipients’ behavior patterns to determine the best times to send emails for maximum engagement.

By automating this process with AI, you can ensure your emails reach your audience when they’re most likely to open and read them—increasing effectiveness and getting more out of the campaigns you’re already running, without a huge increase in budget.
