What is an AI email writer?
An AI email writer is a software application that uses artificial intelligence, particularly natural language processing (NLP) and machine learning algorithms, to help users create email content.
These AI email writing tools can generate text, suggest improvements, and adjust the language to suit different writing styles or goals.
Note that AI email generators are still evolving. It’s best to use AI-generated emails as a starting point. Edit or approve the tool’s suggestions as you see fit. And, as always, make sure to fact-check any AI-generated content.
How to use AI for writing emails
When used to their full potential, AI tools can be a boon for personal communication to business emails and cold email outreach. Our main focus is on AI writing assistants for email campaigns. However, AI offers a range of use cases beyond the world of digital marketing.
Here are just a few ideas on how to integrate AI writing assistants into your email-related workflows.
Generate content
Email communication is a prime channel for generative AI. When prompted, AI can come up with anything from subject lines to body text, making content creation a breeze.
Apart from coming up with entire email drafts from scratch, AI can also enhance the clarity, tone, and professionalism of email content.
Automate tasks
AI models can also be trained to automate your most time-consuming tasks. This includes drafting appropriate replies or sending follow-up emails.
Some AI email assistants even offer advanced tools for marketing automation workflows and dynamic personalization.
Analyze emails
AI tools can also summarize email content, presenting you with key points that you can refer to in the future.
Others can go further and analyze the tone, intent, or context of your emails — and even suggest email responses.
What’s clear: we’ve only just brushed the surface. AI offers a wide range of benefits to help you write better emails and streamline your email management.

7 best AI email writers
Looking to bolster your email marketing efforts? Here are the top AI-powered email tools to consider.
1. Brevo
At Brevo, we’ve been working on new features to help our customers make the most of their email marketing campaigns. Our platform offers user-friendly tools, such as the Drag & Drop email editor and 40+ free email templates.
Our native AI assistant has become a stand-out feature. Use it to:
- Craft email subject lines that boost open rates. Ask the assistant to suggest different subject lines, giving different prompts such as “Use humor,” “Personalize the email,” or “Keep it short.”
- Create email content from scratch. Generate email headlines, body paragraphs, and call-to-action (CTA) buttons.
- Edit existing content. Select the content block you want to improve. For instance, the AI assistant can help you translate the content or adjust the tone.
We even use Brevo’s AI assistant to empower our own marketing campaigns. Here’s how we used it to come up with a compelling subject line for the February edition of our last blog newsletter.
Pros
- Ease of use. Brevo’s biggest advantage is in its simplicity. The AI assistant is incredibly intuitive, making it accessible for beginners and tech savvy marketers alike.
- Built-in functionality. No need to switch between tools. The AI assistant allows you to generate emails directly from Brevo’s platform, making content creation seamless.
- Analytics. Writing emails is one thing, but it’s important to track whether your content works. Brevo helps you monitor the real-time performance of your campaigns, including click-through rates, open rates, and deliverability.
- Integration with Brevo’s CRM tools and plugins. Apart from email, Brevo offers multichannel tools (e.g. SMS, WhatsApp, live chat) and popular integrations (e.g. WordPress, Shopify).
Cons
- Less advanced AI models. Brevo is a great choice for those looking for basic, easy-to-use AI writing features. Depending on your needs, you may wish to seek out a tool with more advanced language models.
- Part of a comprehensive marketing and CRM suite. Some features may be unnecessary for users who are only looking for an AI-powered generator.
Pricing
The AI assistant is available on Brevo’s free plan, which includes 300 emails/day and up to 100,000 contacts.
You’ll need to upgrade for more advanced features, such as A/B testing and predictive sending. Paid plans start at $9/month.
We recognize that Brevo doesn’t suit everyone’s needs, which is why we invite you to discover it for yourself.
2. Google Gemini AI
Google Gemini is an AI-powered feature integrated into Gmail. It helps users draft emails, summarize threads, and edit messages to improve clarity and tone.
To use Gemini in Gmail, click the "Help me write" button to draft a new email using a free-form prompt. The "Polish" feature also allows users to refine existing drafts by selecting options like "Formalize," "Elaborate," or "Shorten," adjusting the tone and length as needed.
Gemini also offers other functionalities such as summarizing emails. This helps users understand key points and respond efficiently.
We tested Gemini and found it incredibly useful for both business and personal correspondence. Here’s an example of a meeting request email generated with Gemini.

Full Gemini integration is primarily offered through Business and Enterprise Workspace accounts, starting at $7/user/month.

3. ChatGPT by OpenAI
When it comes to generative AI, ChatGPT has been leading the helm. It stands out as an email writing assistant. Given its advanced language models (e.g. GPT-4), ChatGPT is one of the best tools for creating natural, human-like text.
As with all AI-powered tools, what you input into the model is key to getting high-quality results. That’s why ChatGPT prompts for email marketing make it easier to run compelling campaigns.
When creating content here at Brevo, we’ve found ChatGPT especially useful for brainstorming ideas and overcoming the dreaded writer’s block. Here’s how we used ChatGPT to come up with ideas for our monthly blog newsletter.
Pros
- Efficiency. ChatGPT can swiftly generate content, draft email campaigns, and respond to customers. This frees up marketers to focus on strategic planning and creativity.
- Cost-effectiveness. Using ChatGPT can be more affordable than hiring a team of writers, as it automates content creation and reduces labor costs.
- Consistency. ChatGPT is a great way to ensure consistent messaging across campaigns, maintaining brand voice and reducing the risk of human error.
Cons
- Generic messaging. Although ChatGPT excels at generating text fast, it may come across as generic. Human oversight and creativity is still fundamental to creating impactful content.
- Limited email marketing features. ChatGPT on its own doesn’t offer HTML templates or other core email marketing features. However, its language models have been integrated into external email marketing tools.
- Data concerns. As with all AI tools, it’s crucial to double-check the generated information. ChatGPT furthermore saves all prompts, questions, and queries entered into the system. This may include sensitive data, which can be used to train AI models.
Pricing
ChatGPT offers both free and paid plans. The free plan gives you access to GPT-4o mini. It’s suitable for general tasks and casual use.
Paid plans start at $20/month and unlock access to GPT-4, which gives you more advanced and nuanced responses.
