Email marketing is still a powerhouse for reaching customers, but keeping up with the demand for fresh content can feel like a full-time job. If you're a marketer, you know the feeling of the content treadmill all too well. This is where AI has started to make a real difference. Modern AI tools do more than just automate sending emails; they help you create, personalize, and improve your content on a scale that just wasn't feasible before. At eesel AI, we experienced this ourselves when we used AI to generate content and saw our organic presence grow significantly.

In this article, we're giving you a hands-on review of the six best email marketing AI tools we've found. We’ll break down what each one is good at, who should use it, and how much it costs, so you can figure out which one makes sense for your business.

What are email marketing AI tools?

They're applications that use artificial intelligence to help with different parts of your email marketing process. Think of them as more than just schedulers. They’re built to make your campaigns smarter and more effective without adding a ton of extra work.

Here’s a visual breakdown of what they usually do:

• Content Generation: They can write subject lines, body copy, or even whole email campaigns based on a simple prompt you provide.
• Personalization: They can customize emails with specific product recommendations or offers for each user, based on that person's data and past actions.
• Optimization: These tools can analyze your data to figure out the best time to send an email, run A/B tests on your copy, and even predict how well a campaign might do.
• Segmentation: They can automatically sort your contacts into different lists based on their behavior or demographics, which helps you send more relevant messages.

How we chose the best email marketing AI tools for this list

To give you a credible and transparent review, we measured each tool against the same set of standards. Here’s what we paid attention to:

• Core AI Capabilities: We focused on tools with genuinely useful AI features for content creation and optimization, not just basic automation for scheduling.
• Use Case Focus: We picked a mix of platforms that cater to different needs, whether you're in e-commerce, B2B SaaS, or just need to generate content.
• Ease of Use: A good tool should have a straightforward interface that a marketing team can start using without weeks of technical training.
• Integration: We looked for tools that play well with other common marketing software, like CRMs, analytics tools, and e-commerce websites.
• Value: The price had to be clear and offer a decent return on investment for the features you get.

The 6 best email marketing AI tools

Here’s a closer look at each of the top tools, covering their strengths, weaknesses, and what you can expect to pay.

1. eesel AI blog writer

A great email campaign needs valuable content, and eesel AI blog writer is built to create the high-quality articles and newsletters that power your marketing. It's more than just a copywriter; it's a complete content creation platform.

You give it a single keyword, and it generates a full, SEO- and AEO-optimized article that’s ready to go live. It does context-aware research to pull in relevant data and automatically includes assets like images and infographics. It even finds and embeds relevant Reddit quotes and forum insights to add social proof. We used this exact tool to grow our daily impressions in just three months by scaling up our blog content production.

Pros and Cons:

• Pros: It produces publish-ready content, includes all the necessary assets, and optimizes the output for search engines and AI answer engines. Plus, it's free to try.
• Cons: It's a specialized tool for generating content, not an email service provider. You'll still need another tool to handle email delivery and manage your campaigns.

Pricing:

You can generate your first blog post for free to see the quality for yourself. After that, plans provide 50 blog generations for $99.

2. Jasper AI

Jasper AI is a well-known AI copywriter with a huge library of templates for all kinds of marketing channels, including email. It’s a solid option for teams that need to produce a variety of copy on a tight schedule.

The platform has specific features for writing email subject lines, promotional copy, and entire campaigns. One of its standout features is Jasper IQ, where you can upload your brand voice, style guide, and product details. This helps the AI generate content that sounds consistently like your brand across all communications.

Pros and Cons:

• Pros: It's very flexible, with over 100 templates and a browser extension that lets you use it on different websites. It also has strong security features, like SOC2 compliance.

Pricing:

The Pro plan starts at $69/month when billed monthly, or $59/month if you pay annually. There's also a custom-priced Business plan for larger teams.

3. Encharge

Encharge is a marketing automation platform made specifically for B2B SaaS companies. Its AI and automation are geared toward encouraging user actions and improving retention with targeted communication.

The platform is particularly good at behavior-based triggers. This means you can send automated emails based on how users interact with your app. For instance, you could send a helpful tip if a user seems stuck on a feature or a congratulations message when they hit a milestone. Its visual flow builder makes it simple to map out user journeys, and it integrates with tools like Stripe, HubSpot, and Segment.

Pros and Cons:

• Pros: It offers automation that is tailored to the SaaS customer lifecycle. The platform connects with a wide range of marketing and sales tools.
• Cons: It's less suited for e-commerce or B2C companies. Some important features, like event-based segmentation and integrations with Salesforce, are only on the more expensive Premium plan.

Pricing:

4. Klaviyo

Klaviyo is a popular email and SMS marketing platform created for e-commerce. Its AI features are all about driving sales and personalizing the customer experience.

Klaviyo's AI toolkit, called K:AI, gives you predictive analytics for things like customer lifetime value (CLV) and churn risk. This helps you spot your best customers and those who might be about to stop buying. It integrates deeply with platforms like Shopify, which allows it to generate personalized product recommendations based on a customer's browsing history and past purchases.

Pros and Cons:

• Pros: It provides deep data integration for e-commerce stores, with built-in revenue tracking and over 350 pre-built integrations. It also handles both email and SMS marketing in one place.
• Cons: The price is based on the number of active profiles, which can get expensive as your list grows. Some users have noted that high-volume senders are sometimes required to upgrade to a costly enterprise plan.
  

  Agreeing with most other comments, Klaivyo gets you the most features and is hard to find a good alternative. I switched to Omnisend when they raised prices a few years ago, it was ok, definitely cheaper but you lose out on more than you save. Ultimately, I cleaned my list and came back to Klaviyo.

  Reddit

Pricing:

There's a free plan for up to 250 contacts. Paid plans begin around $60/month for 2,500 contacts, and the cost goes up from there.

5. ActiveCampaign

ActiveCampaign is a platform that rolls email marketing, automation, and a sales CRM into one. Its AI features aim to create what it calls "autonomous marketing" by linking customer data directly to your communication workflows.

Its AI tools include Predictive Sending, which analyzes when people open emails to deliver messages when they're most likely to be seen. It also offers AI-powered lead scoring to help sales teams focus on the most promising leads. The AI Campaign Builder can even generate entire email sequences from a simple prompt, mapping out a series of messages for a specific goal.

Pros and Cons:

• Pros: The built-in CRM provides detailed customer insights for very personalized campaigns. Its automation features are quite advanced, and it offers over 900 integrations.
• Cons: With so many features, the interface can feel a bit complicated for new users. Some of the best AI features, like predictive sending, are only available on the higher-priced plans.
  

  Primary complaint about AC: 1. Slow servers 2. Doesn't provide insightful metrics at lower plan (on the Starter $19/mo plan). Their metrics is dog tier stuff at this level 3. Too big of a step for me to pay $50 given my situation.

  Reddit

Pricing:

The Plus plan, which has many of the AI features, starts at $49/month for up to 1,000 contacts when you pay annually.

6. Mailchimp

Mailchimp is one of the most recognizable names in email marketing, famous for its user-friendly design. It has recently added generative AI tools to make the platform even more helpful for small businesses and creators.

Its AI tool, Intuit Assist, helps users generate content for email campaigns, suggests audience segments with predictive analytics, and offers recommendations on things like the best time to send. These features are designed to make marketing easier for people who don't have a dedicated team.

Pros and Cons:

• Pros: The platform is easy to use, which makes it a great choice for anyone just starting out. It has a wide selection of pre-built templates and a decent free plan to get you going.
• Cons: Its AI features are more basic when compared to the other specialized tools on this list. The cost can add up quickly if you have a large contact list, and advanced features are locked behind the Standard and Premium plans.
  

  Mailchimp works well for most needs, Klaviyo if you want a multichannel tool, i.e. want to also send texts.

  Reddit
