TL;DR — Top 7 AI Email Generators

Why Trust Me?

I’m obsessed with researching, testing, and writing about software tools, so business owners can make the right decision. I also use generative AI tools in my workflow, so I understand how to use them and what features make a difference. 

What Is an AI Email Generator?

An AI email generator (or AI email writer assistant) is a tool that uses artificial intelligence (AI) to help you write and respond to emails—just enter a prompt describing what you want and get an output in seconds. 

How does an AI email generator accomplish that task?

Well, AI email generators are trained on vast amounts of data to understand and generate human-like text. 

So when you give it a prompt describing the purpose of your email and the tone to use, the AI draws on this knowledge to create an email that meets your requirements. And what does this mean for you?

Instead of writing your emails from scratch, you get a starting point that you can tweak as needed, saving you lots of time and mental energy to channel into more important tasks. 

Plus, unlike outsourcing this task to a virtual assistant, an AI email generator is more budget-friendly and available all day, everyday. 

Key Features To Look for in an AI Email Generator

Most AI email generators build on their core functionality with unique features to streamline the email writing and management experience. 

Based on your needs, some of these features may or may not be necessary. Here’s a checklist to keep in mind as you evaluate the different options in this list:

Integrates With Tools in Your Email Workflow

Whichever AI email generator you choose, it should work right where you need it—whether it’s inside your email app, newsletter, or sales prospecting tool. This saves you the hassle of switching between multiple apps and copying and pasting emails back and forth. 

Generates Quality Content

Let’s face it—we love that AI can help us with email writing, but nobody wants to receive emails that sound robotic; so check whether your chosen tool produces better-than-average first drafts. 

And if you aren’t happy with your drafts, you should have the option to regenerate the output or write followup prompts to improve their quality. 

Customizes Emails With Your Tone Preference

Your AI email tool should let you set a tone—whether it's formal, casual, or funny—so your emails sound like you wrote them. 

Some AI tools let you save these tone preferences, so they’re automatically applied to all of your future emails and will save you the hassle of tweaking this for every single email. 

Corrects Grammar and Spelling Errors

No matter how many times you read and re-read your emails, certain grammar and spelling errors will always escape your scrutiny, but an AI email generator with built-in error detection catches all of those mistakes before you hit send. 

Some AI email generators take this up a notch by offering style suggestions to improve your email’s clarity and readability.  

Personalizes Emails Sent to Prospects

Personalizing emails sent to prospects is especially important for businesses and sales teams sending outreach emails. 

An AI email generator with this feature lets you pull in details from a prospect's LinkedIn profile or website to make your emails more relevant to them. 

And if you’re sending emails in bulk, the tool should make it easy to personalize those emails with a single click. 

Supports Multiple Languages

If you communicate with clients and partners in different countries around the world, an AI email generator with a built-in translator is helpful. It translates your emails with the click of a button, without losing the tone or message.

Top 7 AI Email Generators—Overview, Pros & Cons, and Pricing

Now that you know what to look for, let’s dig into our list of the top email generators. We’ll cover everything from the key features to their pros, cons, and pricing. 

1. beehiiv: Best for Content Creators Looking To Streamline Their Newsletter Workflow

beehiiv is a newsletter platform that helps you do just that in its minimalist and user-friendly interface. And with beehiiv AI, you've got an AI email assistant right where you need it.  

Instead of drafting your newsletter emails from scratch, just enter a prompt in beehiiv AI to whip up subject lines, outlines, and email content. You can specify the email’s length and adjust its tone to match your brand voice.  

And what if you’ve already written your first draft?

Well, beehiiv AI can make the draft even better. Use it to complete sentences, fix spelling and grammar errors, improve readability, and maintain a consistent brand tone with just a few clicks…it works like magic!

However, you need to upgrade to beehiiv’s paid plan to access beehiiv AI. Paid plans start at $39/month for 1K subscribers.

2. Google Gemini: Best for Gmail Users Looking To Quickly Write and Respond To Emails

When Google launched Gemini (formerly Bard) in 2023, it was only accessible as a conversational chatbot for basic queries and research. Since then, Google has integrated Gemini into its Workspace apps—Docs, Sheets, Slides, and, yes, you guessed it…Gmail.

Inside Gmail, Gemini works at the inbox and email levels. 

When you’re ready to compose a new email, activate Gemini’s Help me write button in the bottom toolbar to generate a first draft. 

And if you activate Gemini inside an email thread, you can use it to summarize emails, list action items, and draft replies. 

Meanwhile, if you activate Gemini inside your inbox, it can execute actions like retrieving all unread emails for the week, surfacing emails that require a response or action, and getting order details from your past purchases. 

Pros:

• Lets you regenerate email drafts 

• Has sample prompt templates for getting started

• Uses the formalize, elaborate, and shorten commands to improve your email drafts

Cons:

• Email drafts can be very generic at times

Pricing: The basic version of Gemini is free and accessible to everyone with a Gmail account, but you can upgrade to Gemini Advanced, which uses a more powerful AI model to generate better outputs. 

If you’re a regular Google user, you can purchase Gemini Advanced as part of Google’s One AI Premium plan, which costs $19.99/month. When you sign up, you get the first month free, and it comes with additional perks like 2TB of storage and priority access to new features. 

And if you’re subscribed to Google Workspace, you can get the Gemini Advanced add-on under the Gemini Business and Gemini Enterprise plans for $24/month and $36/month. These plans unlock enterprise-grade privacy and security features, keeping your data and conversations safe. 

3. Shortwave: Best for Drafting Authentic Emails and Scheduling Meetings

Shortwave is an email management app that connects to your Gmail and organizes your inbox, so you can keep the most important ones front and center. This prevents you from becoming overwhelmed and helps you get into the right headspace, even before using Shortwave AI.

Like Gmail, Shortwave AI helps you write emails, summarize long threads, and pull out action items from them. 

But here’s what sets Shortwave apart: it learns your writing style from past emails and generates drafts that sound like your own. 

You can also set preferences, like always starting with "Hi, [Name]" or including a specific meeting link when booking meetings. 

Plus, Shortwave syncs with Google Calendar, so you can ask the AI to check your availability on specific days and respond to emails with your availability. 

And when you highlight the finalized date and time in your email, tap "Schedule with AI" to set up a calendar event….yep, without leaving your inbox.

Pros:

• Has sample prompt templates for drafting emails or replies

• Translates email threads and responds to them in any language

• Uses the AI search to research complex topics and retrieves specific insights buried in your email 

Cons:

• It’s only compatible with Gmail and Google Workspace accounts

Pricing: Shortwave’s free plan gives you access to their AI assistant summarizing and replying to emails, drafting new ones, and surfacing your availability via Calendar integrations. 

The Personal plan costs $8.50/month per user and unlocks the AI-powered search tool with a 1-year email history. 

The Pro and Business plans cost $18/month per user and $30/month per user. They unlock the AI personalization feature and extend the AI search history to 3 years and 5 years respectively.

4. Superhuman: Best for a Seamless Writing Experience Across Platforms

Like Shortwave, Superhuman is an email management app for keeping your inbox organized and improving your focus. 

However, Superhuman works with Gmail and Outlook and syncs with most web, desktop, and mobile devices, so you can use Superhuman AI wherever you go.

Use Superhuman to quickly generate email drafts—just jot down a list of phrases and Superhuman AI will turn them into a full-blown email draft. 

As your conversation grows into a thread, the auto-summarize tool keeps an updated summary at the top, so you don’t lose track.

There’s also the instant reply feature that automatically creates multiple responses to your emails. So when replying to emails, you only need to select a relevant response, tweak it, and hit send!

Thanks to Superhuman’s minimalist interface, high loading speed, and shortcuts for navigating the platform, the email writing experience is so much faster and smoother.

Pros:

• Uses Ask AI to retrieve specific information from your emails

• Streamlines email collaboration with your team using mentions and the team comments and scheduling tools

• Polishes your writing with its shorten, lengthen, simplify, improve writing, and rewrite in my voice commands

Cons:

• There’s no free plan or trial.

Pricing: The starter plan costs $30/month per user and unlocks most of its AI tools as well as team collaboration features. 

However, to access the Ask AI feature, you’ll have to upgrade to the Business plan, which costs $40/month per user.

5. Microsoft Copilot: Best for Outlook Users Who Want To Optimize Email Drafts for Clarity

Microsoft’s Copilot works as a standalone chatbot and inside its productivity tools—Word, Excel, PowerPoint, Teams, and Outlook. In Outlook, Copilot lets you quickly write and respond to emails.

When you open an email thread and click Summarize, Copilot creates a list of the key points with links to jump to the relevant sections. It also suggests reply templates based on the conversation, or you can create your own custom prompt.

When you click the Copilot tool in Outlook’s top toolbar, you have two options: Draft with Copilot for generating emails from a prompt (with a specified tone and length) and Coaching by Copilot that reviews an existing draft and suggests ways to improve its tone and clarity. 

Pros:

• Regenerates drafts or tweak them with custom prompts

• Uses Schedule with Copilot to schedule meetings from an email thread, review, and finalize

• Searches Outlook emails via the Copilot chatbot, and it will give you a summary, action items, and links to the relevant emails

Cons:

• Only works with Microsoft accounts 

Pricing: While Copilot’s chatbot is free for everyone, you need to pay to access it inside Outlook and the other productivity apps. 

Copilot Pro costs $20/month per user. It’s for individuals who want to access Copilot inside Microsoft's web apps. 

Meanwhile, Microsoft 365 Copilot costs $360/year per user (annual billing only). It’s for businesses that want to access Copilot across their entire productivity suite, including Outlook and Teams. 

6. Warmer: Best for Freelancers Looking To Personalize Outreach Emails

Warmer is a web app that generates personalized emails for pitching your products and services to prospects. It has a super simple interface that lets you do just that, no bells and whistles.

To generate a personalized introductory email, you follow a simple three-step guide. First, enter your company details and what you're pitching. Then, set your goal—whether it's booking a meeting or getting a response. Finally, add your prospect’s LinkedIn or website URL.

Based on these responses, Warmer will generate a personalized email, along with five alternate openers that you can mix and match. 

While the content output is good, you might still need to tweak it, especially if you need a longer email that includes specific product details and an appointment booking link. 

Pros:

• Has a very low learning curve 

• Adds multiple identities for your different businesses or product offerings

• Uploads a CSV file to generate personalized bulk emails with a single click

Cons:

• There’s no option to write follow-up prompts to improve the first email draft

• Warmer doesn’t help with sending personalized followups

Pricing: Warmer’s free plan gives you 10 credits for generating 10 personalized emails. For more credits, you have to upgrade to a higher plan. 

The Starter, Basic, and Plus plans cost $59/month, $97/month, and $279/month for 500, 1K, and 5K credits respectively. 

7. Reply: Best for Sales Teams That Need a Prospecting Tool To Generate Bulk Personalized Emails

Reply is a prospecting tool for sales teams to find new prospects, nurture them through multi-channel sequences (including email), and convert them into customers. Thanks to Reply’s built-in AI assistant, Jason AI, you can generate personalized emails at scale.

To get started, select your target prospects, enter a prompt, and Jason AI will generate personalized emails based on their contact details—name, industry, job title, and LinkedIn profile. 

If the first draft doesn't feel quite right, write a followup prompt to refine it or apply one-click commands to adjust its grammar, tone, or length.

When prospects reply, their responses drop into your Reply Inbox. 

With Jason AI’s reply handling turned on, it’ll auto-generate responses and save them as drafts for your review. All you need to do is make any final tweaks and send them off. 

Pros:

• Splits test email subject lines and content 

• Uses the email scoring tool to gauge the likelihood of your emails getting a response and feedback to improve

• Connects to your Google Calendar and lets Jason AI check availability and book meetings on your behalf

Cons:

• Steep learning curve due to extensive features

Pricing: Reply doesn’t have a free plan or trial. However, Jason AI is available on all paid plans, and pricing starts from $59/month for 1000 active contacts.

Best Practices for Using AI Email Generators

To make the most of AI email generators, you need to understand how to use them well, so here are some best practices to keep in mind:

Enter Clear Prompts

Be super specific when writing prompts for an AI email generator. Outline the purpose of the email, highlight any key information that needs to be included, and specify the target audience, the tone of the email, and its length. The clearer your prompt, the better the output will be.

Customize Generated Content

While AI email generators can produce good drafts, they’re not perfect. 

If the output doesn’t match your requirements, regenerate it or enter a custom prompt to make it better. Then, review the content for accuracy and relevance, make any necessary brand voice and text format edits, and hit send.

Ensure Ethical Use and Data Privacy

When using an AI email generator, only input information that you’re comfortable sharing. But if you plan on sharing any private and sensitive data, check the tool’s data handling and usage policies. Make sure that it isn’t monitoring, storing, or using your data to train its AI models.

Power Up Your Newsletter Emails With beehiiv AI
