10 Best AI Email Writers: Boost Efficiency in 2025

The marketplace for AI email writing tools is brimming with options, but not all AI email writers can improve email quality and enhance efficiency.

Whether you’re involved in email marketing, sales, or customer support, you’ll want a tool to help you manage large volumes of emails while maintaining high communication standards and ensuring personalized responses. You’ll also need a solution that seamlessly integrates into your current email platforms to avoid disrupting workflows.

After testing the most popular AI email writers, I narrowed the list to the best ten, considering integration capabilities, ease of use, and innovative features that genuinely save time. Jasper.ai stands out with its wide toolbox of automations to help streamline your entire email marketing workflow while maintaining your brand voice across emails (and other platforms).

You can try out Jasper.ai for free or keep reading for more detailed insights on other AI email writers that might suit your specific needs.

What We Look For in the Best AI Email Writers

Aside from being easy to use, an efficient AI email writer should tick a few other boxes to offer real value. Here’s what I focused on during my research.

• Quality and on-brand output. I only included AI email writers that can produce well-structured and error-free text. These AI tools also allow you to maintain a consistent brand voice across emails.
• Personalization. Win and retain your customers with personal emails. Every platform I listed offers versatile style and tone options, allowing you to craft correspondence that speaks to your customers.
• Automation. The AI email tools I selected come with email templates and AI prompts to help you automate routine (and often time-consuming) tasks, such as responses and follow-ups.
• Editing tools. All AI email writers I included come with useful tools for editing and improving text, such as rephrasing and summarizing. Some of them generate various versions of your text and even let you test their performance.
• Integrations. Most AI email writers on my list easily integrate with different email and text-processing platforms, such as Gmail and Google Docs, to maintain workflow continuity.

1. Jasper.ai: Best for Automating Your Email Workflow

Jasper’s use cases simplify the process of creating effective emails that engage your audience. These templates help you generate catchy subject lines and a compelling email body, even offering suggestions on send times to improve your email’s opening rate.

It’s not just about individual emails – Jasper’s Campaigns feature lets you create end-to-end marketing campaigns for email and other platforms. Based on the brief you upload and assets you choose (emails, social media posts, landing pages, etc.), Jasper generates a full-blown campaign in your unique brand voice to ensure consistency across formats.

Jasper’s offerings fall on the pricier side, and to get access to more advanced features, such as Campaigns, you’ll have to subscribe to the Pro plan or above. Still, you get good value with access to 50+ templates, multiple brand voice options, and an image generator. While there’s no free plan, Jasper offers a 7-day free trial to let you gauge its effectiveness without immediate commitment.

Features

• 50+ content templates. In addition to the Email Subject Lines template, you can use other Jasper templates to automate your email processes, such as the ones for generating paragraphs, press releases, and feature-to-benefit sections.
• Improve emails with on-brand images. Jasper’s art generator crafts images tailored to your style and preferences. Additionally, Jasper acquired Clipdrop, an AI-driven platform for image creation and editing. Running on Stable Diffusion 3, Clipdrop ensures your visuals stay perfectly aligned with your brand.
• Project management. On the Pro plan, you can access Jasper’s project management tool, which lets you view your tasks in board and calendar view. This can be useful for organizing and scheduling your email communications.
• Integrations. Jasper’s Chrome and Edge browser extension allows you to implement its tools in any of your web-based apps, such as Google Docs. Also, Jasper lets you integrate third-party software like Webflow for creating website content and Surfer for improving SEO.

2. Rytr: Best for Multilingual Emails

Of all the AI email writers on this list, Rytr is the easiest to use, but that doesn’t mean it doesn’t offer plenty of functionality for crafting emails and other types of content. One of its standout features is the ability to draft emails in 35+ languages, which is incredibly useful if you communicate with international customers on a regular basis.

You get several email use cases to choose from, such as email replies, CTAs, and newsletters. There are versatile tone options, ranging from assertive and humorous to more fine-tuned choices like urgent and worried. You can also set up different creativity levels for your content (though I’d stick to Optimal for best results!).

Rytr’s pricing model is competitively cheap, even at its highest-tier plans. While the free plan has limitations (only 10,000 characters per month), the cheapest paid plan gives you access to unlimited content and priority support. For more extensive needs (and to unlock languages), the Premium plan remains affordable and offers significant value with features like custom use cases and multilingual content creation.

Features

• Content variants. Rytr can generate up to three email draft versions, which you can test on your subscribers to see which one works best.
• Tools for quick editing. The Ghost Rytr feature lets you change tone and length and rephrase or compose entire paragraphs from any selected text up to 300 characters. It’s particularly handy for making quick edits, such as refining a sales pitch or adjusting customer service responses.
• My Voice. This tool analyzes a sample of your writing and mirrors your tone when it creates content. On the Premium plan, you can create multiple custom tones to match the needs of different projects or clients.
• Chrome extension. Rytr’s useful Chrome extension lets you input content directly into your emails, cloud documents, and social media.

3. Writesonic: Best Content Tools for Drafting Emails

Writesonic’s Emails V2 generator is specifically designed to produce highly engaging email content. Just enter the recipient’s details (name and position), describe the type of email copy you want, and Writesonic will give you three email drafts you can insert into the editor to enhance. Though it lacks the versatility of Jasper’s use cases, it’s particularly effective in creating subject lines, CTAs, and cold emails.

And if you’d rather have an interactive session, the Chatsonic feature goes beyond the limits of a mere chatbot. You get real-time web search, fact-checked content, and the ability to attach any type of file for analysis, including images, PDFs, audio files, and websites. Chatsonic can also write in your brand voice, ask follow-up questions to ensure high-quality output, and optimize your prompts for the best results.

Writesonic caters to a broad audience with its range of plans, making it accessible for freelancers and businesses alike. While the free plan is a good way to test the software, the affordable Individual plan includes unlimited generations, brand voice options, and 50 credits per month for advanced tools.

Features

• AI Article Writer. If you run out of ideas for captivating or converting email content, Writesonic’s AI Article Writer also works great for generating short copy.
• Highlights. This feature allows you to quickly generate accompanying promo copy for your content, such as social media posts, newsletters, and SEO meta tags.
• Image and voice generation. Writesonic’s suite of tools includes Photosonic for high-quality image generation and Audiosonic, which converts your text into human-like voices. These features expand the range of multimedia content that you can produce directly from the platform​.
• Botsonic. This paid add-on lets you create AI assistants trained on your data, which is particularly useful for resolving customer queries.

4. HubSpot AI Email Writer: Best for Sales Emails

If you’re an existing HubSpot customer, using its AI Email Writer makes perfect sense – you’ll be able to write, format, send, and analyze your emails within the same platform. HubSpot’s ecosystem specializes in marketing and customer relationship management (CRM), so its AI Email Writer is particularly good at generating sales emails.

You can start by choosing one of HubSpot’s customizable email templates (a welcome email, new product launch, e-commerce re-engagement, etc.). Once you hit the Generate content button, you’ll begin a step-by-step process of AI email creation. You’ll need to let the AI know the purpose of your email, key selling points, CTA you want to include, and your writing style. Once you generate the email, you can either edit it or ask HubSpot’s AI to tweak it further.

Every plan – even the free one – includes HubSpot’s AI email writing features. That said, more advanced tools, such as unlimited email tracking or email A/B testing, are only available with paid plans. HubSpot’s flexible structure allows you to mix and match modules, such as marketing, sales, and CRM tools. Just be aware that the price can increase significantly depending on your requirements and team size.

Features

• AI prompt commands. You can use “slash” and “highlight” commands to edit and generate new content in your emails. There is a limit of 4,000 tokens for prompts (1 paragraph equals approximately 100 tokens).
• Sales emails on the go. HubSpot’s comprehensive mobile app lets you generate and edit emails from anywhere. You can also use the HubSpot Sales Chrome extension and the HubSpot Sales Office 365 add-in to further expand your reach.
• Advanced campaign features. Once you’re happy with your email copy, you can save it as a template, send it right away, or schedule sending as a part of your campaign. You can also test different versions of the same email to see which one performs best.
• Email tracking. When you launch your email campaign, your HubSpot CRM database automatically records campaign data for you (contacts and conversations), so you can track open rates and lead submissions.

5. Copy.ai: Best Email Prompt Library

Copy.ai offers an extensive library of prompts to enhance your writing, with a dedicated section for email marketing. You’ll find prompts for creating newsletters, email surveys, and opt-in forms. You can even develop entire email outreach or lead generation campaigns.

Copy.ai provides versatile use cases to help automate your marketing and sales workflows but template-wise, its email efforts feel somewhat limited. Still, it can generate email subject lines, create personalized cold sales emails based on LinkedIn URLs, and turn documents into ready-to-email press releases.

Copy.ai’s free plan is probably not enough if you require a solid email workflow as it only gives you access to one seat and 2,000 words in its Chat feature. If you run a small team, I suggest trying out the Pro plan – you’ll get 5 seats, unlimited words, and 500 workflow credits.

Features

• Wide set of integrations. Copy.ai integrates with hundreds of apps through Zapier and you can use its features in many email and messaging platforms, such as Mailchimp and Slack.
• Custom brand voice options. In addition to choosing from predefined tones, like “Friendly” and “Professional,” you can also describe your desired tone in a few words and even ask Copy.ai to mimic a celebrity.
• Infobase for your brand. This feature lets you gather important brand-related information, such as brand guidelines and product services in one place. You only need to input information once and assign a specific tag. After that, it’s available whenever you need to create content, such as emails or blog posts.
• Free writing tools. Copy.ai provides a range of free tools that can come in handy while drafting emails, such as a sentence and paragraph rewriter, a CTA generator, a lead enrichment tool, and more.

6. AI Writer: Best for Email Outlines

Like all AI email writers on this list, AI Writer’s Email Composer generates content based on the information you provide. This includes the purpose of the email and your desired tone. But unlike most email writing tools I highlighted, Email Composer does lack in some areas – there’s no prebuilt tone and style options, it’s only available in English, and it doesn’t let you edit content directly from its platform.

What Email Composer does best, though, is give you a list of key points to cover in your email, making it a great tool for creating outlines. It will also generate a subject line and the body of the email based on the suggested key points.

AI Writer’s prices are high compared to other similar tools, and every plan imposes limits on content generation. Still, it doesn’t lock features under high-tier plans so you’ll get to use all its features, even on the most basic plan. In addition to Email Composer, this includes an article writer, a tool for suggesting topics, a social media post generator, and more.

Features

• Fact-checking with sources. AI Writer specializes in generating academic-like content. It includes live citations for every factual statement, making it an efficient research aid for academic institutions that also want to send out email campaigns.
• Quick-edit tools. AI Writer has several nifty features to help you enhance your email content, including proofreading, summarizing, and text rewording tools.
• Tailor-made content. Designed for long-form content, AI Writer’s Article Writer can easily double as an email writer – especially if your mailing list is very niche. You can specify the number, length and content of individual paragraphs, giving you great control over your content.
• Topic Suggest 2.0. AI Writer can suggest the most relevant and trending subtopics you can use for your weekly, monthly, or quarterly newsletters.

Other Notable AI Email Writers

7. Writerly

Writerly works particularly well for generating cold emails. You can set up your email’s language, tone, and persona, and generate a number of versions. Based on your input, Writerly will create content you can insert into a simple document editor and tweak to suit your needs.

While you can use Writerly to craft basic emails, it lacks more advanced features such as diverse email templates and a powerful chatbot. Still, its interface is incredibly easy to navigate, which makes it a great starting point if you’re new to AI email writing.

8. ChatGPT

The OG AI writing tool, ChatGPT is a conversational chatbot that can generate content quickly on any subject. ChatGPT excels with shorter texts, especially when it comes to rewording or expanding existing content. To get the most out of it, you’ll need to refine your prompts (sometimes multiple times), but it remains a valuable tool for writing assistance or ideation.

For advanced users, ChatGPT also lets you create custom chatbots trained with your data, which you can implement in customer service conversations. You’ll need to get on a paid account to use this feature, though.

9. Shortwave

Shortwave is a chat-based email assistant that can generate emails from scratch or with prompts. One standout feature is that it provides AI-powered email search, allowing you to access specific conversations by asking questions from your inbox.

However, Shortwave lacks email templates, brand and style options, and editing tools, making it better suited for personal conversations rather than email workflows. Also, it’s only available for Gmail.

10. Flowrite

Flowrite specializes in drafting personalized email replies. It reads your emails and creates multiple replies you can use immediately or edit. It picks up details such as names to make messages personal, and it can generate replies based on your input, such as including special greetings in your emails.

However, much like Shortwave, Flowrite doesn’t provide use cases and AI prompts, which makes it less suitable for email marketing purposes but a handy tool for writing professional emails.

These Are the Best AI Email Writers to Streamline Your Workflows

My recommendations help increase productivity by reducing the time spent writing and organizing emails. I’ve made sure they integrate well with your workspace and help you maintain consistent brand voice across emails (and other content). However, the best solution for you depends on your specific needs.

If you’re looking for a way to streamline your email (and other) marketing campaigns, Jasper.ai is my top recommendation. Jasper.ai offers versatile use cases to speed up email creation and its intuitive process of automating campaigns helps keep your style consistent across formats.

On the other hand, if you want an affordable tool to help you communicate with international customers, Rytr has what you need. It allows you to create content in over 35 languages, and it’s one of the easiest AI email writers out there.

Or, if you’re looking for a powerful chatbot to assist you with email copy, Writesonic is a great option. Writesonic also offers a built-in AI image generator to help you create on-brand visuals for your email and any other type of content.
