Artificial intelligence is here, and it’s crushing barriers in every industry.

Email marketing is no exception- the best AI email assistants are here to help you quickly slash through your inbox and redirect your time to more important tasks.

How can an AI email assistant help you out?

  • Write personalized emails faster than ever before through the use of AI tech.
  • Smartly auto-respond to specific emails, so you don’t have to.
  • Help you organize your inbox.
  • Pull in prospect contact information to help you customize quickly.

A lot of the current email assistants are Chrome extensions that can pop up right within your email so that you have everything you need all in one place.

With that being said, these are all in their infancy on how they will help you organize and automatize your inbox. But it’s exciting to see what’s in store for the future, as I’m sure these tools are only going to advance quickly over the next two years.

What Is The Best AI Email Assistant?

Here’s a list of the best AI email assistants right now. I’ll continue to update this as soon as more enter the market and as I gain access to beta mode.

1. Ellie AI Email Assistant

Write Replies Faster

The Ellie email assistant is designed to help you respond back to emails in record time. After signing up and downloading the Chrome extension, you will get a bunch of reply options to choose from.

Here’s what it will look like:

After you click “Write”, you’ll get an entire email drafted for you in seconds.

Ellie AI Pros & Cons

  • It pops up right within your Gmail, so it’s extremely easy to use. Just choose a sentiment, and it writes your response based on the original email.
  • The actual writing was spot on. It reminded me of the same quality I would get with any other AI writing tool.
  • The more you use it, the smarter it gets. It will start to understand your writing style over time and craft emails in your voice.
  • You’re limited on the response options.

Ellie Pricing

I would recommend something other than the casual plan. If you’re sending less than ten emails a day, then I just don’t see how this would save you a lot of time in the end.

Ellie Verdict

This is an extremely promising tool. The fact that it integrates straight within Gmail makes it so easy to use, and the responses I’ve trialed have been great so far. It’s one of my favorite tools so far.

2. SaneBox

Inbox Management

Did you know that the average person receives 121 emails per day, and sends out 40 emails per day?

No matter how hard we try, keeping a clear inbox is a huge hit to your productivity streak (these productivity quotes can help inspire you!).

So what’s a person to do?

Easy, try out Sanebox, the platform that doesn’t let your inbox make you go insane.

Sanebox Experience

Essentially how it works, is that it sorts through your emails for you like your own personal secretary.

The emails that they decide are “unimportant” go into a unique folder called “SaneLater”. That way, when you wake up in the morning to check your emails, only your important emails are left in your inbox.

SaneBox Features

Here’s a list of the features you have to choose from:

  • SaneLater inbox: Emails that you can address later in the day and not ruin your productive morning.
  • SaneBlackHole: Send emails here to teach the program that all future emails should be trashed.
  • SaneNews: Annoying newsletters or updates.
  • SaneCC: Any email you’re CC’d in.
  • Reminders & Attachments: You can set reminders for yourself and send attachments to the cloud.

Sanebox Pros and Cons

  • The artificial intelligence technology will over time learn which emails should always go directly to your inbox, and which ones are junk.
  • You’ll also get a “daily digest” email where Sanebox gives you an overview of emails for the day, and you can train the program right from that email.
  • Works on Gmail, Office, and Apple email.
  • You still need to go through your “SaneLater” inbox once or twice a day, but you should do this later in the day when you’re not at peak productivity.
  • I wish that they had a way to flag a keyword to add a label. For instance, I get tons of emails asking for guest posts and I wish they could just automatically organize these emails appropriately for me.

Sanebox Pricing

Notice you only pay for the features you want (see the features above).

Sanebox Verdict

Sanebox is a nicely affordable way to boost your productivity levels. We all check email in the morning, so instead of wasting your time on junk mail, you can zone in on only the important things that require immediate response.

3. Warmer AI

Personalized Emails

Now, I have had months of experience with Warmer AI and use it as an AI lead generation software. If you’re a company or individual that has to do a lot of cold email outreach and you want to personalize these emails, then Warmer AI is a great tool to use.

Essentially, this AI email writing assistant will write a personalized email for you by scanning through the company’s website or LinkedIn Profile (whichever you provide them). It then pulls personal details into the email.

I used this specifically for guest post outreach, where I would spend HOURS learning about the person I was asking a guest post from. This does it in seconds.

Warmer AI Features

Here’s what the dashboard looks like when I upload a CSV sheet:

  • Have your team upload a CSV or Google Sheets. I found it best to have my virtual assistant fill out a contact name, LinkedIn profile, company website, and then email address.
  • It will then scan their information and create five personalization options for each person. Choose the one you like best.
  • It isn’t an email outreach software in itself, so I would simply copy and paste the personalization back into my Sheets for GMASS to send the actual emails out.

Warmer AI Pricing

It can be pretty pricey, with a start pack coming in at $59/month. But you’ll likely need a lot more credits than that.

Warmer AI Verdict

If you’re looking to level up your email campaigns with individualized personalization, then Warmer AI does a great job of actually increasing email response rates from my experience. However, their cold email outreach tool can be a bit pricey.


Write Custom Sales Emails

Lavender is an AI email assistant that is focused on composing the most compelling sales email.

First, download the Chrome Extension. Then, open up a new email. Within your email, you’ll see a little purple icon on the right that allows you to find prospect information, generate emails, and score your current one for engagement.

Here’s the profile view:

Here’s the Scoring View and how it helps you with suggestions:

Lavender AI Features:

  • Allows you to integrate with Salesloft, Gmail, Outlook, and Outreach email clients
  • Where this platform really shines is its email recommendation tool, which is a must for cold emailing. It gives you recommendations on how to make your email more impactful.
  • They also include all the information about your prospect that you gained from socials. That way, you can personalize the email more quickly.
  • Easily drop in GIFs to your email to make them more engaging.
  • Unfortunately, many emails I tried didn’t find much information tied to their Gmail accounts, so this wasn’t as useful.
  • The scoring could use some work. It said my copy was great, and I don’t think that would get me any guest posts.

Lavender AI Pricing

Lavender AI Verdict

This tool absolutely wowed me with potential. I’m sure in a few years’ time; we’re going to have all the information we need in a few seconds from our Gmail. However, it wasn’t as effective as I would have hoped for quite yet.

5. MailButler Smart Assistant

AI Email Writer & Chrome Extension

MailButler is a more all-encompassing AI email assistant that has tons of bells and whistles to help you with your emails.

All you do is download a Chrome extension, which works side by side with Gmail, Outlook, and Apple.

With this, you can get through your follow-up emails in record speed.

MailButler Features

  • Schedule emails to send at a later time (it even suggests the best time to send an email).
  • It syncs with AI productivity apps like Trello or Asana.
  • They have tons of email message templates that you can use to write emails faster.
  • They have an AI writer that helps you draft emails right within your inbox. You simply tell it what you want to say, and it drafts the email (kinda of like ChatGPT).

MailButler Pricing

It’s important to note, that in order to get access to the AI writing assistant, you need to purchase the “Smart Plan”.

MailButler Verdict

If you’re looking for the best AI email assistant that will both help you write emails, but also help you with other features like scheduling, new signatures, and contact management, then MailButler is a great choice for you.


Cold Outreach AI

I’ve written quite a bit about, most relatable when it comes to companies that need to participate in a lot of cold email softwares. Fortunately, they continue to stay ahead of the curve by implementing their own AI email assistant embedded within their program.

This means you get all of the features you already expect with a cold outreach program, with a boost from AI technology. Features

Let’s take a look at some of their existing features:

  • Create drip email campaigns that are fully automated to reach your audience (new customers, existing customers, auto-followups, etc). This is a great option if you need an AI sales software.
  • Email warm-up capabilities (basically, don’t get your Gmail penalized by Google and be reported as spam).
  • Tons of ways to find new leads, including email search and LinkedIn connections.

Here’s the new AI tech they’ve recently rolled out:

  • Let help you brainstorm engaging subject lines to increase your open rates.
  • Their AI writer will help you create compelling copy to help you increase conversions.
  • AI writing can be geared towards sales, upselling, promos, and a few more.
  • The AI writer has been trained on winning copy, so it can help you improve your existing campaigns by making them more compelling, shorter, or anything else you may need.
  • They can translate into dozens of languages (no more needing an AI transcription software, it does it for you). Pricing

Pricing depends on how many email accounts and customers you need to send out to per month. Verdict

If you are in need of a cold outreach AI email assistant to help you write compelling copy and convert more customers, then is a great one to check out.

7. ChatGPT

Break Through Writer’s Block

Everybody is talking about ChatGPT. It’s probably going to be one of the biggest buzzwords for 2023. So what exactly is ChatGPT?

ChatGPT is software created by OpenAI, a company that is pushing the bar when it comes to deep learning and natural language processing (NLP). It can answer your questions for you, write songs, write articles… it seems like the possibilities are endless, and it’s only going to be smarter.

So it’s only natural that the world quickly discovered the benefits when it came to email writing.

So how can it help you with your outreach or sales emails?

  • Help you write compelling subject lines.
  • Help you write the reply email quickly.
  • You can download the ChatGPT extension so that you can have it near your inbox.
  • It doesn’t integrate with your email platform, so you would have to copy and paste.

ChatGPT Pricing

Totally free to use for version 3.5, but I highly recommend paying $20 a month to get access to the 4.0 version.

ChatGPT Verdict

ChatGPT is the ability to construct long messages that are extremely intelligent- similar to an AI writer like Jasper would (you can see what they do in my Jasper AI review). I loved that you could use the extension. However, it was always at capacity when I tried to use it, so it’s just not reliable at this time.

8. Flowrite

Writing Prompts

Flowrite is an AI email assistant that’s focused on helping you reduce writing time and create better emails. It’s a Chrome extension that attaches an AI writer next to your inbox for convenient use.

Flowrite Email Experience

You can see the extension pop up to the left of my Gmail as pictured below:

All I clicked was “meeting request” and typed “meeting for Friday at 3 pm” (see above). Here is the email that it generated:

My name is Samantha Brandon, and I am the Founder of Samantha Brandon LLC. I would love to have the opportunity to meet with you and discuss potentially working together.
Our company specializes in (area of expertise), and we believe that we could be a valuable asset to your team.
Would it be possible to schedule a meeting for Friday at 3 pm?
Hopefully, we’ll get to speak soon! Thank you for your time.

I was pretty impressed that it created that entire email when all I wrote was “meeting on at Friday 3 pm”.

Here are other Pros & Cons of Flowrite:

  • It allows you to import a few AI templates, such as cold outreach, accepting an email, meeting requests, scheduling, and self-introduction.
  • It constructs great emails that allow you to present yourself to potential prospects as confident and engaging.
  • I wish it also added a subject line, but it doesn’t at the moment.

Flowrite Pricing

They’re generous with a 30-day free plan; then it’s pretty affordable thereafter. I do recommend upgrading to a paid plan.

Flowrite Verdict

I actually really enjoyed Flowrite as I felt the AI email was well constructed, and I could see improving your conversations while minimizing your time in your inbox.

9. Missive

Group AI Email Assistant

If you’re operating a company with various departments, how do you keep all the communication streamlined?

Everyone now has ten channels to communicate through, from emailing, texting, WhatsApp, social medias…. thankfully, Missive is on a mission to fix this. Now your email inbox can look like this:

You can also chat with your Team from within the email platform and assign emails to members of your team, which is golden.

Missive Features

Their ultimate goal is for all email communication to be in one place.

Here’s a breakdown of what they can do for you:

  • You have both a Team inbox (where all the emails go) and the Assignee’s inbox (the individual). This allows the team to assign themselves and work with the same customers for continuity of service.
  • Automated rules allow you to work through your inbox even quicker.
  • They now have the option to integrate directly with OpenAI (ChatGPT) to help you draft better emails quicker and more efficiently than ever before.

Missive Pricing

You need to purchase the “Productive” plan in order to get access to the AI integrations, but they also give a generous free plan to play around with first.

Missive Verdict

If you run a company with various departments such as support, sales, etc, then I think Missive is a company you should really test out to streamline and boost your Team’s productivity.

What is an AI Email Assistant?

Frustrated with having to respond to emails manually?

An AI email assistant is an extension or program that utilizes artificial intelligence and machine learning to automate or streamline the process of responding to emails.

AI-driven email assistants can detect patterns in incoming emails, identify keywords and phrases, generate personalized responses, and then draft an email copy in under a few seconds. This is a huge level-up from spending hours on email templates for your team.

Think of this like a level-up from “smart compose” that you’re probably already familiar with on Gmail.

And this is just the beginning of what they can do in the email management process.

Benefits of AI Email Assistants:

If you’re looking for a way to create more automation within your business processes, an AI email writing tool will help your business ultimately respond, clean, and write emails more efficiently.

  • Quickly draft a relevant reply email in under a few seconds: This AI tool has been trained on compelling marketing copy to save you hours in drafting engaging content.
  • Create replies written in your voice as it learns your style.
  • Help you organize your email account by automatically sorting through your inbox.
  • Integrate within your current email client, such as Google, Apple Mail, or Outlook (depending on the assistant).
  • Team Collaboration: No more confusion on who is working on what, you can have task management right within your inbox.
  • Error-free communication thanks to grammar technology.

Who is an AI Email Assistant For?

While the answer may seem like “everybody”, I think these AI assistants would really help SMBs boost their productivity and communication. Some of the programs I love the most that happen to be the best time-savers are Missive, Snov, Sanebox, and Warmer.

Ultimately, I love them the most for:

  • Sales rep that can gain tons of use out of the AI-powered email assistant.
  • Marketing Professionals engaging in cold outreach
  • Entrepreneurs engaging in hundreds of emails per day and needs help with organization.

Things to Improve:

  • I would like to see it automatically draft and send emails automatically. This would actually save time because it would act like a virtual assistant and do this for me, allowing me to only focus on the most important emails.
  • Integrate with more email software. If you’re a large company doing a lot of email outreach, then it would be great to integrate AI writing assistants within these programs.

Frequently Asked Questions (FAQs)
