Jasper AI is one of the most popular AI email writing software platforms. It’s a favorite for a reason: it has a diverse range of potential use cases, multilingual support, and an aptitude for training custom tones of voice to ensure your emails still sound like you.
Custom Voices – If you’re worried about your AI-generated emails not sounding on-brand, you can train Jasper to write just like you. This can help ensure consistency as well as save you much-needed time.

Who it's Best For
Jasper AI offers over 70 templates, making it a great choice if you want to combine email marketing with various writing projects. Its Chrome extension also allows for grammar and spelling checks while writing on any site.
Due to its versatility, I found that Jasper is an ideal AI writing co-pilot for a variety of use cases, extending beyond professional use to students and personal messaging.
However, its higher price ($39/month) may deter some users. If you are looking for a cheaper option, my research highlights Rytr as a more accessible option in terms of cost ($7.50/month).
Email Segmentation, Email Templates, AI Summarization
Why We Picked It
HubSpot’s AI-driven email writer is a recent addition to its full CRM platform, which offers solutions for marketing, ecommerce, content creation, and sales teams. It’s a truly comprehensive marketing solution that’s now giving itself the edge with smart AI tools such as its email writer.
First of all, HubSpot is the only provider on this list which offers a free email signature generator and template, which will help you create an email signature that’s on brand and includes your vital business information.
HubSpot offers a small but diverse range of ten email templates as well as tools to help create a snappy email subject line and engaging email copy. Plus, during my testing, I found that it offers slightly more advanced analytics features than the other tools in this list, such as stats on delivery, open rate, and click rate.
Features
AI Email Signature Generator – A slick email signature should not be overlooked as a critical part of any professional email, and HubSpot’s AI email signature generator template makes this very quick and easy to create.
Email Segmentation – I was impressed by HubSpot’s advanced email marketing features, such as its email segmentation. This capability allows you to tailor on-brand messages for specific audience segments, increasing open rates and engagement.
Email Templates – HubSpot offers easy-to-customize templates that make designing effective emails quick and simple. Once you’ve chosen a template, you can use its AI writing assistant to generate a captivating headline and craft engaging email content that will resonate with your audience.
AI Summarization – HubSpot’s AI summarizer helps your sales and customer service teams stay productive and informed about the customer journey. It turns complex customer interactions in the form of emails, calls, and web chats into concise summaries that can be shared across different departments.
Pricing
The good news is, you can access HubSpot’s email writer for free. But more advanced AI features you can only get with paid plans which are detailed below:
Plan

Free – This plan provides the tools small businesses need to email new leads and measure the success of these interactions. It supports up to five users and offers free marketing, sales, service, content, operations, and commerce tools. The image generator and AI assistant are not included.
Content Hub Starter – This will enable you to upgrade your content marketing efforts and introduces the AI assistant and image generation premium hosting. You also get the ability to remove HubSpot branding from your assets.
Starter Customer Platform – This plan is for businesses that require more advanced features to power their marketing, sales, service, content, and operations activities.
Content Hub Professional – This package allows you to create and manage personalized, engaging content experiences with advanced features like podcasts, content remix (repurposing across multiple channels), memberships, AI translation, and dynamic pages.
Content Hub Enterprise – You’ll have the ability to streamline content workflows and ensure brand voice consistency across multiple channels. It offers advanced features like team organization, content approvals, and activity logging.
Who it's Best For
HubSpot’s AI email writer is suitable for mass marketing emails as it’s an integrated tool within the larger HubSpot platform. This means you can quickly structure, send, track, and analyze your email campaigns in one place.
However, if you’re looking to create campaigns on a smaller scale, HubSpot may be unnecessarily complex. In that case, I’d recommend a more straightforward AI writing assistant such as Rytr.
Pros
Email template to create professional-looking emails quickly
Fully integrated with HubSpot marketing and sales for insights
Free to use
Supports email segmentation
AI email signature generator
Cons
Valuable insights require integration with HubSpot marketing plans, which require payment
Scalenut is one of the leading AI writer tools for generating professional emails. It specializes in organic marketing and SEO.
I’ve found the combination of SEO with attention-grabbing email marketing campaigns to be a match made in heaven to build brand awareness and customer loyalty.
Features
Sales Email Generator – Describe your product, brand, and context to quickly create compelling cold emails and subject lines.
Content Optimization – Scalenut can optimize your existing content to gain more organic traffic from search engines.
Keyword Planner – Scalenut’s nifty tool performs keyword research for you based on your primary keyword. It generates clusters as well as relevant data like search volume and keyword density.
Pricing
Scalenut provides four paid subscription options: Essential, Growth, Pro, and Enterprise. Below is a table outlining the monthly and annual costs of each plan:
Plan

Pro

Enterprise – Custom limit on SEO articles, unlimited webpage analysis, advanced AI models, enterprise-level security, tailored onboarding.
Scalenut does not offer a completely free plan, but it does offer a 7-day free trial across its four paid plans. You’ll need to provide your credit card information to start the free trial, but you can cancel at any time.
Who it's Best For
Scalenut is best for salespeople or marketers wanting to generate sales outreach emails while also optimizing their content for SEO success.
During my extensive research and testing, I found Scalenut to be a relatively commercially focused platform, making it less suitable for those wanting to write personal emails or those working in academia. Jasper AI and Rytr offer more flexibility if SEO and sales outreach are not relevant to your goals.
Rytr is one of the best AI email assistants as it offers affordable plans and has a free option. It offers a range of templates, languages, and both preset and custom tones of voice. Since it offers a lighter range of features, I also found it very easy to navigate.
Features
Custom Voice – Train Rytr to sound just like you with a custom tone of voice in addition to its preset voices.
Email Template – Rytr offers 40+ templates, including designated email and email reply templates, to ensure the output you receive is specific to the formalities of your use case.
Chat – If you prefer to work in the chatbot Q&A style, you can access Rytr’s chat feature and quickly ask it to generate emails, edit existing copy, and brainstorm email marketing campaign ideas.
Pricing
Rytr’s pricing includes a free forever plan, as well as Unlimited and Premium paid-for tiers. The table below outlines the monthly and annual costs of each plan:
Plan
Free
Unlimited
Premium
Monthly

$9/month

Premium – Unlimited AI content generation, multiple tone matches, 100 plagiarism checks per month, 35+ languages per month, priority support, custom use cases.
All plans come with a Chrome extension, 20+ pre-programmed voice tones, and access to a community of Rytr users.
Who it's Best For
Rytr offers a solid range of features for an impressive $7.50 per month, outshining its competitors when it comes to pricing.
This makes it a great solution for anyone looking to implement an AI email assistant without a huge financial investment. That said, Rytr’s proficiency at writing long-form content is not yet on par with Jasper AI or Writesonic, so you may find those tools more adept at more complex writing tasks. It also does not offer the same SEO functionality as Scalenut, which may be more suitable for data-focused marketing teams.
Writesonic is another leading AI email writer on the market right now. I like it for its intuitive navigation and option to work in its editor or chatbot, Chatsonic.
It also provides you with a range of tools, including an AI writer and access to Audiosonic and Photosonic, offering great versatility for multimedia projects.
Features
Email Templates – Writesonic offers designated templates for emails, cold emails, and subject lines, which can help you generate accurate results quickly.
Sonic Tools – In addition to text generation, Writesonic offers a chatbot, art generator, and text-to-speech (TTS) editor, which adds an extra level of flexibility.
SEO – Writesonic also offers keyword research, content grading, and insights to improve your search engine rankings.
Pricing
Writesonic offers seven pricing plans, including a free option. The table below details each pricing plan, along with its monthly and annual costs:
Plan

Chatsonic

Free – Try all Writesonic and Chatsonic features for 25 generations per month, 25 one-off free credits for Advanced templates.
Chatsonic – Unlimited Chatsonic generations, but no access to Standard or Advanced templates.
Individual – Unlimited generations on Standard templates, 50 credits per month for Advanced templates.
Standard – Everything in Individual + 1,000 credits per month, automated internal linking, AI keyword clusters, and improvements to Article Writer 6.0.
Professional – Everything in Standard + 3 team members, 3,000 credits per month, AI content gap analysis, and personalized onboarding.
Advanced – Everything in Professional + 5 team members, 6,500 credits per month, and priority support.
Enterprise – Custom team members, custom apps, enhanced security, SSO/SAML login, personalized training, and priority support.
Who it's Best For
Writesonic’s ease of use and versatility with art and text generation, SEO, and TTS make it a great tool for those working with multimedia content.
It’s also a bit cheaper than Jasper AI, while still offering many similar features. Scalenut’s SEO offering is more robust, so I’d recommend it over Writesonic if you’re wanting to enhance your sales and marketing efforts without needing art generation or TTS.
Simplified is a diverse platform that provides AI design, video creation, social media management, and writing services.
This makes it a great option if you need a tool to handle various types of content. It also offers the most extensive range of email templates. The templates can enhance your efficiency, allowing you to achieve your desired results more quickly and with minimal editing.
Features
100+ Writing Templates – In its vast bank of templates, Simplified offers more email templates than any of its competitors, including rejection emails, cold emails, and promotional emails.
AI Chat – It allows you to work with its templates, or in a chatbot style, which can be more familiar if you have experience using ChatGPT.
AI Writer – In addition to email writing, Simplified is also capable of writing blogs, essays, and articles.
Pricing
Simplified AI Writer offers four paid-for plans, including a free forever tier. I’ve highlighted the costs of each of its plans below:
Plan
Free
Pro
Business
Enterprise
Monthly
$0
$18/month
$49/month

Business – Everything in Pro, 600,000 words per month, 5 seats.
Enterprise – Everything included in Business plus additional seats, generations, more brand books, and advanced features for larger teams.
For $24 per month (billed annually), you can choose to subscribe to Simplified One to access Simplified’s AI Design, Video, Writing, and Social Media tools.
Who it's Best For
Along with Writesonic and Rytr, Simplified offers a generous free plan that suits those looking to explore AI without signing up for an expensive subscription.
Like Writesonic, Simplified also offers various multimedia tools such as design, video, and social media tools. This means it’s a great option for creative teams looking for a versatile AI content generator to take care of more than just emails.
However, it lacks Scalenut’s SEO proficiency, so it is not my top recommendation for sales and marketing professionals.
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.
First, you’ll need to provide 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 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.
When you first install the assistant, 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.
The Benefits of Using AI for Email Writing
In this section, I’ll outline some of the benefits of using AI for email writing.
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.
How to Choose the Best AI Tool for Writing Emails
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:
PricingLanguage SupportEase of UseIntegrations
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.
AI email writers are artificial intelligence tools that use natural language processing to automate your email writing.
What is the best AI email writing tool?
The best AI email writing tool depends on your needs. If you are seeking a tool that will adopt your brand’s voice and offer a range of other writing templates, I’d recommend Jasper AI. If you want a tool that can write emails and also offers SEO optimization, then Scalenut is a great option, while Rytr tops the charts when it comes to cost-effectiveness.
What is the best free AI email generator?
Rytr, Writesonic, and Simplified all offer free AI email generation. The best one for you will depend on your needs. If you’re looking for a simple user experience, I’d recommend Rytr, while those looking for high-quality long-form content should check out Writesonic. Simplified is an excellent option if you’re looking to combine design, writing, and video.
Who should use an email AI writer?
AI email writers can be used by anyone. Business owners who are short on time but want to stay on top of their inbox can benefit hugely from AI email writers. Other potential users may be those looking to improve their written communication skills or those who are new to the workforce with less experience in communication in a professional tone of voice.
Can AI emails be detected?
There are AI detectors, but their accuracy is hit-and-miss. They can even falsely identify human-written text as AI-written. There is currently no foolproof way to tell AI and human text apart, but a well-trained eye may suspect overly generic vocabulary and sentence structure. If you are concerned about your AI emails being detected, make your own adjustments to the text to add more personality before hitting send.
What is the best AI email signature generator?
From our list above, HubSpot is our top recommendation of an email generation tool that includes a free AI email signature generator template. Other well-reviewed AI email signature generator tools include Canva, MySignature, and Gimmio.
