10 Free AI Email Writing Tools: Write Emails Better and Faster With AI

Free AI Email Writing

“If your job involves lots of emailing, you may know the frustration of composing the same email over and over.  Well, one way to save yourself from this repetitive task is to use an AI email writing assistant. These AI-based systems are designed to generate content for your email. How? An AI system reads your past emails, analyzes them, and formulates a reply, saving you time and effort.” I didn’t waste time writing this introduction. Instead, I opened an AI-assisted writing tool, typed in two prompts, and hit “Enter.” Voila! I had my content written by a machine. The software I used is just one of the many AI writing assistants that compose emails and generate content based on your inputs. Read on to learn more about these unique tools and how you can use them to generate email content. We’ll also look at some free AI email writing tools and their benefits.

What are AI writing tools?

AI writing assistants are computer software that writes human-like content based on the keywords we feed into their system. They can create any form of text like emails, blogs, social media posts, marketing copies, digital ads, web content, press releases, and reports. Based on your prompts, the tools research, generate content ideas, write and expand text, and check content tone and grammar. These tools can also help with tasks like summarizing text, translating languages, and writing different kinds of creative content. In essence, AI tools also serve as an idea generator, helping you overcome writer’s block and produce high-quality content in a fraction of the time. Furthermore, some tools like Grammarly go beyond checking grammar and sentence structure. They identify monotonous sentences or outdated expressions and suggest replacements. Such real-time editing greatly improves the content quality. Any business professional looking for help writing content can use these tools for personal or professional use. AI email writing assistants are a subset of AI writing tools that generate email content. From subject line generators to complete email copy creators, you can find different AI products for email content. Imagine writing a long email to your colleagues to reschedule a meeting or sending a welcome email to your new customer. AI email writers can write a professional email copy for you in minutes. Sales professionals who use email for outreach campaigns, as well as marketers engaging in email marketing, can use AI email writers to augment their process. Using AI writers with sales and marketing automation tools can further save time and effort.

How do AI writing assistants work?

Any AI tool that writes text in a human language requires three main techniques:

  1. Natural language processing (NLP): Translates human language input into machine-readable language.
  2. Natural language understanding (NLU): Enables machines to understand the meaning of the input from the data.
  3. Natural language generation (NLG): Creates text in human language based on a given input.

AI writing platforms generate human-like content using NLP, NLU, and NLG​​. You can find different tools for NLP, NLU, and NLG on the market. But most AI writing tools are built on a similar, incredibly powerful language model called Generative Pre-training Model 3 (GPT-3). This generative AI guide provides additional insights into how these technologies work.


GPT-3 is one of the latest open-source NLP models built by OpenAI. It has been trained on a massive 570 gigabytes worth of internet data, including a huge volume of text written by humans. This extensive training makes GPT-3 read, understand, and reproduce human language.  AI copywriters like CopyAI, Compose AI, Jasper, and SmartWriter.ai are built on this impressive new technology. They predict not just the next word in succession but create an entire text draft, eerily similar to how humans write.

How to generate email content using AI writing tools

A typical AI email writer requires at least one or two-line instructions about your email and the audience. Once you provide the information, the system creates multiple copies. You can review the content, edit it to suit your needs, and use it. These platforms offer a variety of templates as a starting point to generate content. In Copy.ai, for example, you have email templates like welcome, follow-up, cancellation, and so on. Once you choose a template, you need to input the email subject, choose a tone, and press “Create Copy” to get your email content. Source: Screenshot from Copy.ai Similarly, in Rytr, you can select “Email” as the use case. Then, provide key points, choose the tone of the email, and the number of email content variants you want to see. You need to tap “Ryte for me” for the algorithms to write your text.

Benefits of AI email writing tools

Using AI to write your emails isn’t new. Google’s Smart Compose suggesting words and short phrases in emails has been around since 2018. But it doesn’t draft full emails.  Now, you can opt for several AI email writing tools that not only draft messages for simple prompts like “schedule meeting in an hour” but also generate content snippets for cold and marketing emails.   These tools create immense value for professionals, who spend more than a quarter of their average office time just on emails. Using AI email writing tools makes life easier and emails more effective.  You can analyze millions of data points without tiring, work 24/7, and even save yourself from the dreaded “writer’s block.” With machine learning capabilities, the AI systems not only create content but also improve the process and output via continuous learning.  Here are some other advantages of using AI email writing assistants. 

1. Personalization

A sophisticated AI tool creates highly tailored email content by scraping all possible information from the receiver. It creates hyper-personalized emails in a few minutes based on a LinkedIn profile, a recent achievement or what the company does, or a recent related news article.  SmartWriter.ai, for instance, offers personalization for cold email outreach based on Linkedin profiles or information from the web. You only need to provide the name of the person or company to generate a tailored cold email.  Source: Screenshot from Smartwriter Sales and marketing professionals can leverage these tools to send personalized emails at scale. Such personalization goes a long way in boosting conversions, given that 72% of customers engage only with personalized messages. 

2. Dynamic subject lines

Subject lines can make or break a marketing campaign aimed at increasing the email open rate. AI tools come to the rescue here too. These systems can generate several catchy subject lines based on your inputs. Paired with an AI tool for analytics, such a system can find the best-performing subject lines by performing a/b testing or multivariate testing and automatically optimize the campaign Classified ads site Gumtree used Phrasee’s AI-driven subject line generator and saw a 44% increase in email click rate. Not only did the tool send dynamic subject lines to recipients, but it also monitored what worked for customers and what didn’t and learned to optimize future campaigns.

3. On-brand response

AI writing platforms also standardize email content to suit a particular company style. They can be trained with a specific language model to capture a brand’s distinct tone and writing style so that emails are always consistent and on-brand.  The luxury fashion retail platform, Farfetch, saw a whopping 31.1% increase in its average open rate after leveraging AI-powered content in its email marketing campaigns. It used AI to personalize and provide unique yet on-brand messages to millions of customers.  

4. Improved quality

An AI writing assistant can also be a personal editor for your emails. Many tools analyze the grammar, tone, and sentence structure and suggest changes to the copy in real-time. This ensures you write an error-free copy.

Do AI email writers work? 

AI writers can create a compelling copy for any input you provide. However, they still need a bit of manual editing to check the content and ensure it is what you want. Sometimes, the tools generate strange phrases or bizarre sentences that need rework. Their outputs are only as good as their inputs. AI tools are still learning to bring out the emotion of a human writer.  In their current state, AI platforms still have room for improvement. Nevertheless, AI can save time and effort with its prowess to bring out valid data points, personalize at scale, and provide on-brand quality content. These benefits make it a valuable addition to your writing and marketing toolkit. So, don’t feel shy to give AI email writing tools a try.
