You’ve just spent hours (or days, even) on the email campaign, crafting your copy, perfecting the subject line, getting creative to get those “meh…” unsatisfying type of result. It was hard work, but not smart work. And this is where AI email assistants come in to save the day — they can do a lot of routine tasks, while you can focus on strategy and planning to turn those sad CTRs into groundbreaking ones. 

In this article, you’ll find 12 AI email writing tools that can turn your emails from overlooked to unmissable. Pricing, exciting features, and overviews — all so you don’t have to spend your time searching for yourself.

What are AI email assistants, and why are they important?

AI email assistants are designed to optimize how we create, send, and manage emails. For both marketers and business owners, AI email assistants can be a strategic tool — they can save time, money, and effort, while boosting productivity and performance. How do they do it? Easy — email assistant generates your emails and email campaigns, including the content of your copy, images, CTAs, design, etc. Another way to work with them is to use an email assistant as a creative partner: it can brainstorm ideas, suggest insights, and give feedback on your own plans. Whichever path you choose, the result will be the same — more personalized, relevant, and impactful marketing emails.

How do they work?

AI email assistants work by leveraging machine learning and deep learning. They analyze your email content, audience engagement, and response patterns to provide actionable insights and recommendations. 

Usually, AI tools incorporate either Gen AI models, like OpenAI’s GPT, for example, or predictive analytics. All they need from you is a prompt — description of the task, audience specification, and details that you find important for the best result. In many cases, AI assistants can perform in multiple roles, like copywriter, designer, marketer, or data analyst. 

To give you an example of how this works, we asked Selzy’s AI assistant in “AI generator” mode to create a promotional email for a new beauty concealer. The prompt was very simple. We added a few mistakes, just to check if AI would be triggered by them (he was not!). The picture, text, buttons, and design overall — all his.

We might add that any AI needs heavy input from humans — sadly, it’s not a Michelin star restaurant, but more like a test kitchen with an infinite number of helpers. And you need to treat it like such — improving and tweaking both your prompts and the results you got. If you are not sure about what to ask for yet, you can train on the best marketing prompts for ChatGPT. And one idea is to ask it to improve your prompt to your email assistant. Yes, we are at the point where AI can help us with other AIs.

4 benefits of using AI email tool

AI email assistants work by leveraging machine learning and deep learning. They analyze your email content, audience engagement, and response patterns to provide actionable insights and recommendations. Here are only a few applications of AI email tools:

  1. Saving time on writing and optimizing content: AI tools can suggest optimal subject lines, content tweaks, and even entire email drafts based on your audience’s preferences and past engagement data. For example, when using ChatGPT for email marketing, you can draft newsletters, promotional content, or follow-up messages in minutes while keeping your communication consistent and engaging.
  2. Scheduling and sending emails: These tools can determine the best times to send emails to maximize your open and click-through rates. They can also suggest adjustments in your sending times, email content, format, and sending patterns to avoid being marked as spam or ignored. AI email assistants significantly enhance email deliverability, which sets them apart from traditional email marketing software. AI tools identify and remove invalid or unresponsive email addresses, thereby reducing bounce rates.
  3. Predictive analytics: AI email assistants can forecast the success of your campaigns, allowing you to make data-driven decisions. AI email assistants can track open rate and click-through rate, offering actionable suggestions to improve future campaigns. They can also automate the segmentation of your audience based on various criteria, meaning you can effortlessly send targeted campaigns to different customer groups without manually sorting through your contact list. They can predict trends and customer behaviors — and a lot of brands are now heavily rely on such features. It’s one of the important email marketing lessons from recent years: the right AI tool has already increased marketing-driven purchases by over 35% for some companies.
  4. Personalization at scale: AI writing tools and email-generating tools help you achieve a more personalized level of communication with large audiences. More so, now it can happen in real time, with customers getting emails created just for them and just in the right time frame. Once again, predictive analytics and data insights help them with the task. For humans, that means improved engagement and customer loyalty.

12 best AI email assistants

To find the best AI email assistants, we took an approach similar to the one detailed in our guide to the best AI tools. Here’s a short overview of our selection criteria:

  2. Community engagement: We looked at products tagged “artificial intelligence” on platforms like Product Hunt, Futurepedia, and Future Tools, noting the most popular, followed, upvoted, and liked ones.
  3. Specific focus on email: Lastly, we focused on tools that specifically cater to email. Our selected tools prominently feature “email” as a core functionality on their websites, meaning they specialize in AI-driven email assistance.

Have you gone through our list and are still unsure which one to pick? Or maybe you’re the kind who likes to dive in and choose for yourself? We get it. Selecting the perfect AI email assistant for your marketing needs is more than just picking a popular tool. It’s about finding a solution that aligns with your business goals, fits into your workflow, and matches your communication style. Here are some actionable tips to guide you in making an informed choice:

  1. Assess your specific needs: Start by clearly defining what you expect from an AI email assistant. Do you need it primarily for crafting engaging emails? Do integrations and the diversity of analytics tools matter to you? Or do you want to bring your team’s productivity to a new level?
  2. Prioritize user-friendliness: Opt for a tool that’s easy to navigate, especially if you’re new to AI-powered email marketing. This will make the transition smoother and more effective.
  3. Ensure seamless integration: Check if the AI tool can easily integrate with your existing marketing software and CRM systems, without disrupting the existing workflow.
  4. Focus on personalization capabilities: Select a tool that excels in personalizing emails. The best AI tools should offer features that adapt content to your audience’s unique preferences.
  5. Check what kind of support you can get: Choose a tool that provides strong customer support and high-quality educational resources — both will be invaluable for navigating new features or troubleshooting.
  6. Evaluate cost vs. benefits: Consider the tool’s cost against the potential returns on investment, ensuring it fits within your budget.
  7. Test content for brand alignment: Ensure the tool’s output aligns with your brand voice and messaging. A trial run or a demo will be enough to assess such things.

By following these steps, you can choose an AI email assistant that not only meets your current needs but also scales as your business grows, effectively supporting your email marketing strategies.

Potential challenges of using AI email writers

While AI email writers and assistants offer numerous advantages, like any technology, they come with their own set of challenges. Understanding not only helps deal with them effectively, but also ensures that your use of AI enhances rather than hinders your email marketing efforts. Here are some common challenges you might encounter:

  1. Over-reliance on automation: There’s a risk of over-relying on AI, leading to less human touch in your emails. Striking a balance between automation and personalization is essential.
  2. Data privacy concerns: Using AI tools involves handling customer data, which raises privacy concerns. Ensure the tool complies with data protection regulations like GDPR.
  3. Initial setup time: Setting up AI email assistants can be time-consuming, as they require initial data input and time to learn your brand voice and audience preferences.
  4. Keeping content authentic: AI-generated content might sometimes miss the mark in sounding authentic or matching your brand’s tone. Regular monitoring and tweaking are necessary to maintain the quality and authenticity of your emails.
  5. Cost considerations: While AI email tools can be efficient, they can also be costly. That’s why it’s so important to take another good look at both the tool that caught your eye and your goals before burning your entire marketing budget.

It’s also important to remember that each business might encounter a unique set of challenges, so do not skip that part where you carefully evaluate your very particular business circumstances.

Final thoughts

As we wrap up our exploration of AI email assistants, it’s clear these tools are more than just a passing trend. They’re becoming essential for marketers aiming to make their email campaigns more effective, personalized, and impactful. From enhancing personalization to improving deliverability and increasing the overall team’s productivity, AI email assistants offer a suite of benefits that can significantly upgrade your email marketing efforts.

Still, the key to success lies in choosing the right tool and using it wisely. Remember, the art of how to write a friendly email is still at the core of successful communication, and AI is here to enhance this skill, not to replace it. The human touch remains invaluable. Use AI not just to send emails, but to send the right emails, to the right people, at the right time, fostering stronger connections and driving tangible results for your business.

And as with any technology, being prepared for potential challenges, like data privacy concerns or the initial setup time, will ensure you harness the full potential of AI in your email strategy.
