Your latest email campaign just went live. Hours of work, yet the open rates barely nudge. Frustrating, isn’t it? What if the missing link is smarter, not harder work? 

Meet AI email assistants, the unsung heroes in the world of digital marketing. 

In this deep dive, we explore 12 cutting-edge AI email writing tools of 2023, each designed to turn your emails from overlooked to unmissable. This isn’t about replacing your creativity; it’s about amplifying it. Stick around to learn how these tools can refine your email strategy, ensuring your message resonates and converts.

What are AI email assistants and why are they important?

AI email assistants are innovative tools at the intersection between email marketing and artificial intelligence. They are designed to optimize how we create, send, and manage emails. 

Let’s reflect on two numbers: ​​the value of the AI market is expected to reach nearly $2 trillion by 2030, potentially contributing $15.7 trillion to the global economy. This exponential growth underscores the increasing relevance of AI in various sectors, particularly in marketing.

Email remains a vital communication tool in the digital age. In fact, according to the State of Email Survey 2023 by Mailmodo, 78.29% of marketers named email their top-performing channel in 2022. More importantly, 50.8% of them observed a 2x improvement in their email marketing ROI in the same year. These statistics highlight the importance of effective email strategies, for which AI email assistants are becoming increasingly indispensable.

For email marketers and business owners, AI email assistants are more than just time-savers; they are strategic partners that enhance the efficiency and effectiveness of email campaigns, while bringing the overall team’s productivity to the next level. They employ sophisticated algorithms to analyze your email data, learning from previous campaigns to suggest improvements for future communications. This process leads to emails that are more personalized, relevant, and impactful.

How do they work?

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

  1. 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. This ensures your emails are always on point and engaging.
  2. Scheduling and sending emails: These tools can determine the best times to send emails, maximizing open and click-through rates. 39.4% of businesses sent only 1-4 emails per month on average to each subscriber in 2022, making each email’s timing crucial.
  3. Predictive analytics: AI email assistants can forecast the success of your campaigns, allowing you to make data-driven decisions. They can predict trends and customer behaviors, helping you to stay ahead of the curve.
  4. Personalization at scale: These tools facilitate personalized communication with large audiences. They analyze individual user data to tailor messages, leading to improved engagement and customer loyalty.
  5. Futuristic scenarios: Looking into the future, AI email assistants could evolve to predict customer needs even before they arise, automate cross-channel marketing efforts, and offer real-time personalization based on evolving user data.

Picture this: it’s a busy Monday morning, and as you brainstorm  your next email campaign, your AI assistant alerts you: 

“Based on recent social media trends and user behavior, your customers are starting to show a strong interest in eco-friendly products. I’ve drafted an email campaign focused on your eco-friendly lines and scheduled to launch it just as this trend peaks. I’m also distributing the same message across all the platforms, tailoring it to each audience’s unique preferences.” 

This might be the direction AI assistants are taking.

4 benefits of using AI email tools

Enhanced personalization: AI-driven personalization goes beyond just addressing recipients by their names. It involves tailoring content based on individual behaviors and preferences. For instance, an AI email assistant can analyze past interactions to suggest content that resonates with each subscriber, significantly improving engagement.

Saving time on writing content: AI email assistants can generate entire email drafts, bringing your team’s productivity to the whole new level. 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.

Better analytics and data-driven insights: 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.

Improved email deliverability: 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

They can also suggest adjustments in your sending times, email content, format, and sending patterns to avoid being marked as spam or ignored.

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.

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 both at 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 teams’ 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.
