Best tools for AI email marketing

10 min read

The future is here. Many of the processes that keep email marketing campaigns running on a day-to-day basis are already powered by artificial intelligence (AI). Spam detection, intelligent email composition, subject line generation, template optimization, A/B testing – AI can already be a trusted personal assistant of an email marketer.

However, in some cases, tools based on artificial intelligence tend to do more harm than good. For example, AI can generate decent B2B client sequences, but when it comes to generating texts for B2C emails, even with the specified voice and tone, the generated copy may sound robotic and can be easily distinguished from human-written content. That’s why it’s so important to choose the best options, understand the limitations of each tool for various cases, and use these tools wisely.

In this article, we’ll talk about AI in email marketing and walk you through the best AI-powered email assistants.  The best AI email assistants can help you: 

  • Expedite email replies
  • Rewrite text in different styles
  • Create catchy subject lines, preview messages, and CTAs 
  • Proofread the copy you’ve written

What is AI in email marketing?

AI in email marketing involves using artificial intelligence technologies to automate and enhance various aspects of email campaigns. It includes segmenting audiences, generating emails, optimizing campaigns through testing, providing analytics and insights, and more. 

How AI is a great help in email communication

In essence, AI in email marketing makes it easier for marketers to create email campaigns that are targeted, relevant, and effective for their subscribers.

We’ve asked ChatGPT how it can help email marketers in email communication. Here’s the response: 

But we won’t, of course, limit ourselves to ChatGPT only. Let’s take a look at other tools available that can make our lives easier.

The best AI-powered email assistants

While Canary Mail focuses more on email management and security, it does provide some AI-powered assistance. Canary learns the way you use email. It can write emails, bring to light what needs attention, silence spam, and much more.

Back in 2021, Mailchimp released Content Optimizer which uses artificial intelligence to help email marketing campaigns perform better.


Thanks to its vast trove of data, Mailchimp is in the unique position of being able to identify common patterns of successful marketing campaigns. Content Optimizer taps into this data and uses machine learning models and business rules to predict the quality of email campaigns and make suggestions for improving content, layout, and imagery.

In 2023, Mailchimp introduced a set of generative AI tools for developing content and campaigns. Their Email Generator is designed to help users brainstorm ideas and create content to test in their email campaigns. The new tool offers a menu of options depending on the industry, tone, and goal of the marketing. They can then write a natural language prompt asking the AI to compose an email for purposes such as announcing a sale or including relevant details such as times and discounts. The AI will offer three variations of a possible email, and the user can choose their favorite and tweak it as needed. The AI can also analyze a campaign’s successes and failures and make suggestions for improving the next campaign based on its own history and Mailchimp’s industry-specific data.

Mailchimp is running the Email Content Generator as a beta test for subscribers in the United States, with plans to expand its availability in the near future.

Have you ever thought about using ChatGPT as your personal email assistant? For example, it can help you compose emails using AI. All you have to do is provide it with a short prompt explaining what the email message should be about. However, to get a version of the email that you’re 100% satisfied with, you’ll need to provide a lot of feedback.

Want to write a reply? No problem. Copy and paste the email into ChatGPT and ask it to compose a response. To save time, you may also want to specify the word count and tone of the response.

If you don’t want to read too much text, ChatGPT can summarize emails like in the example below.
