What is an AI Email Writer?
An AI email writer is essentially an AI email generator – an artificially intelligent tool that uses advanced machine learning to help you draft and respond to your professional and personal emails.
How Does an AI Email Writer Work?
AI email writers work by using natural language processing (NLP), machine learning and model training to understand and generate natural human responses to your professional and personal emails.
To use an AI email writer, you’ll first need to provide it with a prompt. This should include details like the intention of your email, the recipient, and your desired tone (e.g. professional, friendly, persuasive). The AI email writing assistant will then analyze your request and use the many example emails it has been trained on to write a unique email.
The sentences will be constructed and ordered in a logical way, informed by the language patterns the AI tool has been trained on. Once you receive the output, you’re free to review and make any necessary adjustments before sending it.

How We Review And Test AI Tools
We base our recommendations on first-hand testing. All the products we feature, have been tested based on the following criteria:
- Accuracy: The accuracy of every AI tool varies and is largely dependent on the AI model used and the quality of the input. We test each tool to gauge its accuracy across the tasks and use cases it supports.
- Performance: We also test how long it takes the AI tool to deliver results and weigh this time against the quality of the output. Quick results mean nothing if the output isn’t accurate, relevant, or what you expected.
- Ethical Considerations: We explore any issues with bias, transparency, and privacy to ensure we recommend only the best artificial intelligence solutions that take these ethical concerns seriously.
- User Experience: We test every AI tool on all the supported platforms to gauge its user-friendliness and whether it works as advertised. We also explore any online documentation available.
- Value for Money: We weigh the features, performance, and accuracy of the market’s best AI tools against their cost to determine their value for money. We also factor in the cost to scale with the platform.
- Features: We test every feature on offer with the service over a two-week period. This includes testing their functionality (whether it’s art generation, or voiceovers, for example) across all the platforms the tool supports.
- Security: From data privacy to ensuring the tools haven’t had a data breach, we take security seriously, checking their regulatory compliance and how vulnerable the AI models are to exploitation.
The Benefits of Using AI for Email Writing
Some of the benefits of using AI for email writing include:
- Consistency in Tone and Style – While they can sometimes sound generic, the best AI tools for email writing will excel at maintaining a consistent tone of voice across pieces of content. They can also be trained to sound like you so there is no abrupt change of tone in your messaging.
- Cost-Effective Content Creation –There’s no denying that hiring a dedicated customer service team member is a significant expense. However, emails need to be responded to in order to build a positive business reputation among your customer base. AI email writers offer a cost-effective solution that may save you from hiring an extra pair of hands.
- Improved Accuracy and Error Reduction – AI email writing tools can help minimize grammar and spelling blunders while improving writing flow. No need to get an extra set of eyes on your work, as AI comes with built-in proofreading capabilities to flag errors before you hit send.
The Best AI Email Generators: Honorable Mentions
The email generation tools above are my top picks, basedon testing, but I’d be amiss not to mention the following three popular tools. I’ll also briefly mention why I did not include them on the main list:
Nanonets
Nanonets helps medium to large businesses automate their workflow processes to make operations more efficient. It can extract relevant information from inbound emails in order to generate appropriate and helpful responses, without the need for human intervention. It’s certainly a good choice for handling large volumes of complex data and reducing the amount of manual admin needed to stay on top of email tasks.
However, I felt Nanonets was too complex and likely too expensive for what most people and small businesses reading this article would need: a trusty, lightweight assistant to draft, manage, and organize emails. It’s less about specific, well-crafted email content creation and more about processing large data sets to improve efficiency in medium to enterprise companies.
YAMM (Yet Another Mail Merge)
YAMM is useful if you or your business frequently sends large volumes of bulk emails which should also be personalized to different audience segments. One of its selling points is that it integrates with Google Workspace so you can send these bulk emails directly from Google sheets, making it easier to send tailored content to large audiences.
I felt YAMM wasn’t versatile enough to include on the main list as it is limited to use with Google Sheets (both a pro and a con, I suppose), so it’ll be les useful to users outside of the Google ecosystem. It’s also more about the sending than it is email creation, which all the email generators on my list do really well.
Gemini AI (Google Workspace Integration)
I probably don’t have to tell you what Gemini is: the long-awaited AI assistant from Google. What you might not know is that when integrated into Google Workspace (Gmail) is can offer AI support for generating email responses and summarizing email threads. It uses Google’s large language models which mean the quality level of it’s content and performance is high.
To be honest, I’m considering adding Gemini to the list. I held back from promoting Gemini too loudly following the teething issues and transition from Bard, but I’ve found it to perform well both as an email assistant and for other uses. It doesn’t offer as many customization options as other tools on my list, though, like Jasper, and again, it’s not ideal for those operating outside of the Google ecosystem, like YAMM.
How to Integrate an AI Email Assistant Into Your Inbox
An AI email assistant should help lighten the load when it comes to email admin. It can learn to sort your inbox and categorize your emails, set up filters, automate tasks, draft responses to emails, and prioritize your most important, urgent messages.
To integrate an AI email assistant into your inbox and start benefiting from this support, you’ll need to simply:
- Choose the AI email assistant you want to use. Do a little research and find one that comes highly reviewed, like Microsoft Copilot or SaneBox (just make sure it looks like a good fit based on what you need it to do).
- Sign up or create an account with the AI email assistant software, and install it as instructed to your device. There will likely be a step around integrating it with your email client (meaning, Gmail, Outlook, etc.) but the provider should make it clear how you do this, and it shouldn’t take more than a few minutes.
- Take a look at what customization options it offers. You should be able to choose whether or not it sends follow-up reminders about unanswered emails, for example, or how often these notifications pop up.
Once it’s installed and you’ve configured it to suit your preferences, you’re ready to start letting the email assistant save you precious time.
Is a Free AI Email Writer Worth Using?
Free AI email writing tools can be worth using, especially for generic, casual, or impersonal emails and for when you’re on a tight budget. They can save you time by quickly generating well-crafted emails that maintain a consistent tone and are free from errors.
That said, free AI writer tools can have limitations in terms of customization, complex topics, and credit limits.
If you’re seeking an email writer for complicated emails where your tone of voice is crucial, I wouldn’t recommend using a free tool. Likewise, if you want to invest in a solution to be frequently used, you may quickly max out its capacity.
How to Use AI for Outlook Email Accounts
The most obvious Outlook AI email assistant to use would be Microsoft Copilot, especially if your Microsoft 365 subscription includes access to this tool already.
This is an AI-powered assistant that can help with all aspects of email management. This includes drafting complete emails based on prompts, summarizing long email threads to give you the key points, drafting responses to emails you’ve received, organizing your inbox, and prioritizing emails to help you stay on top of the most urgent things.
However, if you’re using Outlook but do not have a Microsoft 365 licence or subscription of any kind (meaning you most likely have it for personal use), another option might be cheaper or better suited.
- Mail Maestro AI, for example, which describes itself as the “ChatGPT for Outlook”, in a highly rated Outlook email assistant on Microsoft AppSource which offers a limited free plan and then starts at just $12, which is cheaper than the average Microsoft 365 plan.
- Jasper AI is an AI tool I’ve highlighted as being great to use with Outlook thanks to its nifty browser extension which allows for efficient use in the Outlook platform. Jasper’s also one of the most highly developed AI content generators on the market, meaning it should help you elevate the tone, style, and quality of your email content in a way that Microsoft 365 Copilot can’t.
How to Choose the Best AI Email Writer
There are a few factors to keep in mind when choosing the best AI for writing emails. While many of them offer similar features, there are some key areas where they differ, including:
The AI tool you choose will ultimately be the one that best suits your use case, but price is also a crucial factor. Check to see whether the pricing is monthly or annual and whether it offers a free trial or free forever plan. Also check that the next tiers up are also within your budget should you need to upgrade later.
When working with international colleagues and clients, it’s a bonus to be able to communicate in their native language. Many AI tools make this possible with translation support for over 30 languages. Check to see whether the languages you work in are provided by your chosen tool.
Whether you are an AI whiz or just starting out, it’s advisable to find a tool that matches your skill level. This will help you maximize the potential of the tool. Make use of any free trials and compare them with competitors before deciding on an AI email writer.
It’s a plus if your chosen AI email writer can integrate with your messaging platform, whether it’s Slack or Gmail, so be sure to check if this is possible before committing.
How to Use AI for Email Writing
In this walkthrough, I’ll demonstrate how to use Rytr to generate compelling email copy with just a few clicks.
Create a New Document
Once you’ve created an account with Rytr, you’ll find yourself on the homepage. Simply click ‘New Document’ in the top-left corner to start generating your own emails.
Select a Tone of Voice
Rytr offers various tones of voice to ensure that your writing style is appropriate for your recipient and the subject and context of your email. If you haven’t trained your own custom voice, you can select from one of the 20+ presets, including formal, urgent, and passionate.
Choose Your Use Case
Select ‘Email’ or ‘Email Reply’ from the dropdown menu of use cases available. This will then bring up another input box where you can specify the details of your message.
Describe the Main Points
In the ‘Key Points’ box, enter the subject matter and the context of your communication. This will inform the results you generate, so it is best to give as much detail as possible. This includes details of your recipient, your brand or business, and your intention for reaching out.
Generate Email Copy
You’ll also be able to set the amount of variants you’d like to receive and the level of creativity in your answer. After this, hit the ‘Ryte for me’ button to see your AI-generated email copy.
Edit Output
It’s advisable to tweak the final copy to make it your own. Rytr gives you the option to change the length or tone, or you can insert your own content within the AI-generated text. This way, you’ll give the result a personal touch and ensure that your intent is communicated.
Conclusion: What’s the Best AI Email Writer Overall?
The best AI email writer for you depends on the type of emails you need to create, whether they’re personal, professional, for marketing campaigns, for customer communication, part of a job application… I could go on.
Overall, Jasper stood out to me as the top AI email writer thanks to its versatility with regard to tone of voice and preset templates. This means you can use it for a range of purposes, including all of the above. What’s more, it’s compatible with Microsoft Outlook, so you can receive writing assistance without even having to switch tabs.
Since Jasper is a premium product, this is reflected in its higher strtaing price tag of $39 per month. Businesses that employ Jasper can save time and enhance the professionalism of their communication, leading to a quicker return on investment. However, casual users, students, or smaller businesses may find it difficult to justify the costs. With that in mind, I’d suggest checking out Rytr for a more affordable AI email writer.
