All you need to do is enter what you want to do, additional information, if any, number of copies you want, and the tone, of course. However, you can add your own brand only if you have a paid plan.

Once generated, you can move the output to the editor, and change the language, look for plagiarism errors, and even export to use it as you see fit. 

Though it works similarly to other tools that we have looked at so far, this tool has one distinct feature that sets it apart from the rest. It can search the web and provide you with accurate output with the menial output you enter. Not only that, this tool has two more features to fine-tune your content generation experience: the feature depth option in the tool provides more detailed output, and the feature 'speed' option provides the output more quickly. This feature is not only useful for emails but for everything.


This tool provides a free trial, yet it lacks a free plan. The paid plans vary, starting at $29 monthly and extending up to $599 monthly. For a more curated experience, you can choose their business plan, which offers a custom package designed specifically for your business needs.

7. Flowrite

Flowrite simplifies your email creation using AI. It is like a piece of cake to generate emails using the tool. The tool gives you the complete email copy using various AI email templates under different categories.

Not only that, but they also offer extensions that you can use with other tools like Gmail, Outlook, Yahoo, and even popular platforms like WhatsApp, Zoho CRM, and HubSpot CRM, among a few others.

All you have to do is click 'Start for free' and sign in however you prefer. Add a few details about your job, and you're good to go. You'll need to install Flowrite’s extension since it integrates with your email and messaging apps. Choose the tool you need, and you'll be set up in no time. Once you're in, a box pops up for you to specify whom you're messaging. Whether you're starting a new message or replying to an existing one, just type '/' to use a ready-made template or create your own. Replying? Simply use the phrases the tool suggests, select a template, or write your reply. It'll show you three versions to choose from. Tweak them until you're satisfied, then hit 'use this version'. Copy your message and paste it into your email or messaging app. It's that simple—this tool is designed to make your digital communication easier and more efficient.


They don’t have a free plan, but they offer a free trial. But their paid plans don't cost much either. In fact, their plans start at $5 a month and go up to $24 a month, which gives you unlimited words. 

8. Hyperwrite

If you not only want to create email using AI email tools but also want to create your own email tool using AI for free, you need to check out this tool called HyperWrite. To top it all off, this tool is also an AI writing assistant that is stuffed with free AI tools.

An image of HyperWrite's interface featuring a cold email template to promote the GravityWrite content tool with a conversational tone.

It has a handful of handy AI email tools. First up, the Email Responder is your go-to for generating quick replies to emails without any effort. Then there's this cool tool that helps you come up with catchy subject lines that make people want to actually read your emails. If you need to write a complete email that's got to look sharp and clear, there's a tool for that too, which keeps things straightforward. And for those times you need to reach out to someone new, maybe about a cool product or to connect with someone on LinkedIn, there's a tool that helps you write an intro that doesn't sound like a robot.

Not only that, but 3 other features can take your email to the next level: 

  1. The 'Sources or Use Search function' will find relevant articles and sources to include or use as a background when generating your responses. 

  2. The 'Use Scholar' function will use Google Scholar to find relevant papers and sources to include or use as a background when responding. 

  3. The 'actions, or use the browsing function', will engage with the HyperWrite Extension and use it to take action and complete the given task via your browser. 


This tool doesn't have a free plan. There are 2 paid plans: a premium plan priced at $19.99 a month with slightly limited possibilities, and an ultra plan priced at $44.99 a month with unlimited usage and more sophisticated features.

9. Bard AI

Bard AI is Google’s very own generative AI platform that works similarly to ChatGPT. It can do a whole lot of things for you, from generating all forms of content to emails to complex codes.

A snapshot of Bard AI's chat interface, showing a draft email about enhancing content creation with GravityWrite's AI tool.

Just enter what kind of email you want in the text box and hit enter. Too lazy to type? Click the microphone button, record your input, and hit enter. It gives you three sample drafts every time you generate emails, and you can ask Bard to read the generated email as well.

Not only that, you can modify the generated response by making it shorter, longer, simple, and more casual and professional. Also, you can double-check the response against the Google search results.


Bard is completely free to use, as of now

10. ChatGPT

You guessed it right, next on our list is none other than ChatGPT. It has transformed the way we work and has opened the doors to the world of AI. 

Just like Bard AI, Chat GPT can generate emails, ad copies and more. In fact, the possibilities are endless. 

A screenshot of ChatGPT interface with a draft email highlighting the key features of GravityWrite AI content writing tool.

Enter a simple prompt and hit enter, simple. In no time, you will have a ready-to-paste email in seconds. After generating your email, copy and paste it in your desired email client. 

One downside of ChatGPT and Bard AI is that you need to enter prompts to make this tool work. Also, the output generally looks very unnatural and robotic unless you tweak it with better prompts. 


ChatGPT offers a free plan that uses GPT 3.5. The paid tool is accessible for $20 per month, and it has more sophisticated features like being able to access GPT-4, their most advanced model, and explore a range of functionalities, including browsing, creating, and utilizing various GPTs. Also, unlock a suite of extra plugins such as DALLE, Browsing, and Advanced Data Analysis to enhance your experience and capabilities.


Basically, YAMM is a mail merging software. But it has a set of free AI email tools to simplify your email creation process. 

  1. AI Email Subject Line Generator: A smart tool to get you some catchy subject lines.

  2. AI Email Generator: To help you churn out attention-grabbing emails quickly.

  3. AI Sentiment Analyser: To identify how your email would possibly sound to your audience in real-time.

  4. AI Grammar Checker: To look for any grammar errors and make your emails look tidy.

A screenshot of YAMM's interface displaying a suggested email template to boost writing skills with GravityWrite.

Generating your emails is as easy as pie. Just enter what your mail is all about in 200 characters max, how you want to sound, your preferred writing style, your recipient’s name, and other optional details.


Though all the tools that we had a look at are free, subsequent usage of the tool might charge you. They have three plans: individual, team, and unlimited, ranging from $25 to $150. Should you want a custom plan, you can get that as well by contracting their sales team.

12. Botowski

This tool, called Botowski, is elementary and straightforward. It offers a couple of AI email tools: an AI email writer tool to generate complete email copies for you and an AI email subject line generator.

A screenshot of Botowski's email writer tool with options to choose tone and generate a professional outreach email.

The working of this tool is simple; you enter what you want, and this tool just does that correctly. To fit your writing style better, you can modify the tone of the email; there are 3 tones now. However, the tool is hopefully bringing more of them.


Though these tools work as intended in the free plan, you might need to upgrade your plan to other paid plans: starter, pro, and premium, priced at $19 per month, $49 per month, and $99 per month, respectively, if you’re using this tool in the long run.
