Understanding AI Tools for Email Writing
Let’s start with the basics. What are AI email writing tools and how can they benefit your email writing?
What Are AI Email Writing Tools?
AI email writing tools are programs that use artificial intelligence to craft emails.
Email assistants generally use artificial intelligence to create new content based on a generative AI algorithm. This allows it to predict what text should come next in a sentence/email, based on brief instructions from the user.
Typical uses for AI email writing tools include the following:
Creating first drafts of emails
Lengthening short emails
Shortening long emails
Grammar/spell checks

Benefits of Using AI for Email Writing
There are many advantages of using AI tools for email writing, such as:
Increased Efficiency: the primary benefit of using AI for email writing is increased efficiency. AI tools allow users to write emails quicker, allowing more time for other tasks and reducing the chances of burnout.
Better Personalization: personalized content can be produced more easily using AI tools. Many programs can read past responses in an email thread and make suggestions based on this content, offering quick responses without skimping on personalization.
Error Reduction: while AI must be balanced with input from your team members, there’s no doubt that human error is a real problem. AI helps to combat this, providing error-free content every time - you can also use AI tools to check spelling/grammar quickly and easily.
Email Consistency: keeping your emails consistent is crucial for professionalism, and AI tools are perfect for achieving this. Having different team members working on your email writing can result in contrasting tones of voice, making your brand messaging appear unclear and professional. AI tools help to ensure all emails are consistent in messaging and brand voice, delivering a professional, uniform impression.

Key Features to Look for in AI Email Writing Tools
The features that you look for in AI email writing tools will depend on your brand’s goals and mission.
We’ve listed below the main features that the best AI tools will offer, helping you to narrow down which tools would work best for your business.
Personalization Capabilities
Personalization is super important when it comes to using AI for writing emails. When used properly, AI can create email responses that are bespoke to your customer base, helping to boost open rates and engagement levels.
Advanced personalization features in AI tools include using customer information to tailor emails and analyzing emails sent previously by your brand to ensure your tone of voice is echoed in future emails.
AI tools that don’t use personalization effectively are likely to produce blanket emails that aren’t relevant to your specific customer base. This can hurt your subscriber numbers, with users seeking more bespoke email content from other brands.
Automation and Workflow Integration
It’s important that AI tools integrate seamlessly with existing workflows, and automate repetitive tasks to improve efficiency within your business.
Most good AI email writing tools sit within your email client so that you can easily access AI features while drafting your emails. Alternatively, it may integrate as a browser extension, making it accessible from most tools you choose to use online. If it doesn’t integrate via either of these methods, you’ll need to use the tool separately and manually copy/paste content into your email client which may be more time-consuming for you/your team.
It’s also key for AI tools to automate repetitive tasks to make your business more efficient. This may include automating quick responses, filtering emails into relevant folders, or correcting spelling/grammatical errors.
Quality of Content Generation
Content quality is arguably the most significant feature of an AI email writing tool. If the content that’s being generated is no good, your audience will be turned off from your emails and this could significantly affect the performance of your email campaigns.
AI tools should generate high-quality, coherent, contextually appropriate content to ensure emails receive the best engagement rates. It’s always worth double-checking the content AI tools produce to ensure your brand is coming across as professional and as relevant as possible.
Ease of Use and User Interface
AI email writing tools should be easy to use, with intuitive interfaces that are easy to navigate and use.
Put simply, if a program isn’t user-friendly, you’re not going to want to use it. The whole point of AI tools is to save you time and make your life easier, so it’s an instant red flag if using a tool is an instant headache.
Make use of the free trials that AI systems offer to see which tools work best for your team before committing to a paid plan.

How AI Tools Enhance Email Writing
There are many ways that AI tools can enhance your email writing and make this element of your email marketing quicker and easier for your business.
Check out the below sections to see how AI can help with your email writing process.
Improving Writing Efficiency and Speed
AI tools can help to make your email writing more efficient by significantly cutting down on the time allocated for writing emails.
Many tools create first drafts and email responses based on a brief line of instruction from the user. This is particularly useful if you regularly create emails of a similar nature, as tools can learn the type of emails you usually send and generate responses automatically.
Users will then have more time to focus on other tasks that require more attention, only needing to check the AI response before sending it.
Enhancing Email Personalization
While some people avoid AI for fear of creating blanket, irrelevant content, many AI email writing tools specialize in creating highly personalized email responses.
This is achieved by analyzing user data and behavior and creating email responses based off of this data. This can result in a higher engagement rate from subscribers as the emails are more relevant to them.
An example of this is a tool using subscriber data such as social media profiles to generate specific content that a user would be interested in, and creating an email response including this information. This level of personalization will be more relevant to your audience and will likely result in better click-through rates and engagement rates.
Reducing Errors and Ensuring Professionalism
A fundamental role of AI tools in email creation is to reduce errors and ensure professionalism across your email campaigns.
This is achieved by scanning content for grammatical errors and spelling mistakes and checking corrections with the user before correcting the content.
While this may sound like a feature that is seen across most sites with writing functionality, it’s not prevalent in all AI tools and is essential in maintaining a professional tone across your email responses.
Best Practices for Using AI Tools in Email Writing
AI tools for email writing should be managed correctly for best performance - at the end of the day, you know your brand best and it’s important to work with the tools available to create the best emails for your business.
Check out the below best practices to get the most from AI email writing tools.
Customizing AI-Generated Content
A great way of using AI tools is to customize AI-generated content.
This involves creating content using AI tools and then adding a personal spin to further customize the content. Not only will this make your content more personal, but it will also result in higher engagement rates from your audience as the content will be even more relevant.
Think about your specific goals and audience members when customizing AI content to make your content as relevant to your users and brand as it can be.
Maintaining Brand Voice and Tone
Always remember your brand’s voice and tone when working with AI tools to create email content. The way your brand comes across over email is super important when engaging with your subscribers, and AI-generated content can become generic if you’re complacent in the way you use it.
It’s worth manually checking content regularly to ensure that your brand’s messaging and tone are reflected in your content. You could also choose a tool that learns from your existing email content to make sure the content it produces moving forward is relevant to your customers.
A/B Testing for Optimal Results
Another tip for using AI tools in email writing is to carry out A/B testing. This involves testing out different versions of AI-generated emails to see which perform best and which you should discard.
By carrying out these tests, you’ll learn which AI content to use moving forward, drilling down into what kind of content works best for your brand.
Common Challenges and How to Overcome Them
We understand the common pitfalls that users may come across when working with AI tools and the best solutions to these problems.
Have a read of the below sections to learn from mistakes that others may have made, rather than making these mistakes yourself.
Balancing Automation With Human Input
When using AI in any capacity, you should always remember to balance automation with human input - particularly when it comes to AI email writing tools.
Never overlook the experience that your team has in knowing your brand, and bringing different levels of creativity to your email content. AI tools are fantastic at making email writing more efficient, but human creativity can make all the difference when it comes to creating engaging email.
Strike a balance between using AI tools and your skilled team members to make sure you’re drawing the best features from both sources to create highly relevant, efficient content.
Ensuring Data Privacy and Security
It’s crucial to maintain data privacy and security when using AI tools.
Some tools will analyze customer data to create the most relevant content for subscribers. While this is a feature that can garner excellent results in terms of engagement, you must ensure that you’re being transparent about the data you’re collecting to ensure you’re compliant with data privacy regulations.
Being complacent with customer data can result in high unsubscribe rates and even penalties in extreme cases.
Avoiding Over-Reliance on AI
While AI tools are revolutionary in content creation and efficiency, it’s important to avoid over-reliance on automation.
Only using AI rather than team members for your email writing can result in a lack of brand voice, and may be limited in creativity when it comes to producing highly relevant content for your subscribers.
It’s also likely to be unpopular with your team if you choose to solely focus on AI-generated content rather than tapping into the unique skills of your team members.
AI is best used in connection with human judgment to create a balance between efficiency and creativity.
