The 6 Best AI Email Writer Assistants in 2024

Campaigns – Jasper AI can generate end-to-end marketing campaigns based on your brief, which includes email marketing, landing pages, and online ads.

Custom Voices – If you’re worried about your AI-generated emails not sounding on-brand, you can train Jasper to write just like you. This can help ensure consistency as well as save you much-needed time.

Jasper Art – Visually engaging emails have a higher click-through rate. WhatI really liked about Jasper AI is that you can also generate custom imagery to decorate your email campaigns with it’s pwerful art generator.

Jasper AI has three paid-for pricing plans. The table below highlights the monthly and annual costs of each plan:

• Creator – 1 user, 1 brand voice, SEO mode, Google Chrome browser extension.
• Pro – 6 seats, 3 brand voices, 10 knowledge assets, 3 instant campaigns, and access to Jasper Art.
• Business – Unlimited feature access, performance analytics, enterprise-level security, API access, dedicated account manager, and custom style guides.

Jasper AI offers a 7-day free trial for its Creator or Pro plans. You will need to provide your credit card details to start the trial, but you can cancel at any time.

Jasper AI offers over 70 templates, making it a great choice if you want to combine email marketing with various writing projects. Its Chrome extension also allows for grammar and spelling checks while writing on any site.

Due to its versatility, I found that Jasper is an ideal AI writing co-pilot for a variety of use cases, extending beyond professional use to students and personal messaging.

However, its higher price ($39/month) may deter some users. If you are looking for a cheaper option, my research highlights Rytr as a more accessible option in terms of cost ($7.50/month).

AI Email Signature Generator – A slick email signature should not be overlooked as a critical part of any professional email, and HubSpot’s AI email signature generator template makes this very quick and easy to create.

Email Segmentation – I was impressed by HubSpot’s advanced email marketing features, such as its email segmentation. This capability allows you to tailor on-brand messages for specific audience segments, increasing open rates and engagement.

Email Templates – HubSpot offers easy-to-customize templates that make designing effective emails quick and simple. Once you’ve chosen a template, you can use its AI writing assistant to generate a captivating headline and craft engaging email content that will resonate with your audience.

AI Summarization – HubSpot’s AI summarizer helps your sales and customer service teams stay productive and informed about the customer journey. It turns complex customer interactions in the form of emails, calls, and web chats into concise summaries that can be shared across different departments.

The good news is, you can access HubSpot’s email writer for free. But more advanced AI features you can only get with paid plans which are detailed below:

Free – This plan provides the tools small businesses need to email new leads and measure the success of these interactions. It supports up to five users and offers free marketing, sales, service, content, operations, and commerce tools. The image generator and AI assistant are not included.

Content Hub Starter – This will enable you to upgrade your content marketing efforts and introduces the AI assistant and image generation premium hosting. You also get the ability to remove HubSpot branding from your assets.

Starter Customer Platform – This plan is for businesses that require more advanced features to power their marketing, sales, service, content, and operations activities.

Content Hub Professional – This package allows you to create and manage personalized, engaging content experiences with advanced features like podcasts, content remix (repurposing across multiple channels), memberships, AI translation, and dynamic pages.

Content Hub Enterprise – You’ll have the ability to streamline content workflows and ensure brand voice consistency across multiple channels. It offers advanced features like team organization, content approvals, and activity logging.

HubSpot’s AI email writer is suitable for mass marketing emails as it’s an integrated tool within the larger HubSpot platform. This means you can quickly structure, send, track, and analyze your email campaigns in one place.

However, if you’re looking to create campaigns on a smaller scale, HubSpot may be unnecessarily complex. In that case, I’d recommend a more straightforward AI writing assistant such as Rytr.

Sales Email Generator – Describe your product, brand, and context to quickly create compelling cold emails and subject lines.

Content Optimization – Scalenut can optimize your existing content to gain more organic traffic from search engines.

Keyword Planner – Scalenut’s nifty tool performs keyword research for you based on your primary keyword. It generates clusters as well as relevant data like search volume and keyword density.

Scalenut provides four paid subscription options: Essential, Growth, Pro, and Enterprise. Below is a table outlining the monthly and annual costs of each plan:

• Essential – 100,000 words, 5 SEO articles per month, SEO templates, AI images, factual content.
• Growth – Unlimited words, 30 SEO articles per month, audit and optimize 30 articles per month, 60 keyword clusters per month, analyze 200 webpages per month on a single domain.
• Pro – Everything in Growth + 75 SEO articles per month, 75 keyword clusters per month, and analyze 500 webpages per month on 5 different domains.
• Enterprise – Custom limit on SEO articles, unlimited webpage analysis, advanced AI models, enterprise-level security, tailored onboarding.

Scalenut does not offer a completely free plan, but it does offer a 7-day free trial across its four paid plans. You’ll need to provide your credit card information to start the free trial, but you can cancel at any time.

Scalenut is best for salespeople or marketers wanting to generate sales outreach emails while also optimizing their content for SEO success.

During my extensive research and testing, I found Scalenut to be a relatively commercially focused platform, making it less suitable for those wanting to write personal emails or those working in academia. Jasper AI and Rytr offer more flexibility if SEO and sales outreach are not relevant to your goals.

Custom Voice – Train Rytr to sound just like you with a custom tone of voice in addition to its preset voices.

Email Template – Rytr offers 40+ templates, including designated email and email reply templates, to ensure the output you receive is specific to the formalities of your use case.

Chat – If you prefer to work in the chatbot Q&A style, you can access Rytr’s chat feature and quickly ask it to generate emails, edit existing copy, and brainstorm email marketing campaign ideas.

Rytr’s pricing includes a free forever plan, as well as Unlimited and Premium paid-for tiers. The table below outlines the monthly and annual costs of each plan:

• Free – 10k characters, 1 language, but no plagiarism checks or tone matching.
• Unlimited – Unlimited AI content generation, 1 tone match, 50 plagiarism checks per month, 1 language, priority support.
• Premium – Unlimited AI content generation, multiple tone matches, 100 plagiarism checks per month, 35+ languages per month, priority support, custom use cases.

All plans come with a Chrome extension, 20+ pre-programmed voice tones, and access to a community of Rytr users.

Rytr offers a solid range of features for an impressive $7.50 per month, outshining its competitors when it comes to pricing.

This makes it a great solution for anyone looking to implement an AI email assistant without a huge financial investment. That said, Rytr’s proficiency at writing long-form content is not yet on par with Jasper AI or Writesonic, so you may find those tools more adept at more complex writing tasks. It also does not offer the same SEO functionality as Scalenut, which may be more suitable for data-focused marketing teams.

Email Templates – Writesonic offers designated templates for emails, cold emails, and subject lines, which can help you generate accurate results quickly.

Sonic Tools – In addition to text generation, Writesonic offers a chatbot, art generator, and text-to-speech (TTS) editor, which adds an extra level of flexibility.

SEO – Writesonic also offers keyword research, content grading, and insights to improve your search engine rankings.

Writesonic offers seven pricing plans, including a free option. The table below details each pricing plan, along with its monthly and annual costs:

• Free – Try all Writesonic and Chatsonic features for 25 generations per month, 25 one-off free credits for Advanced templates.
• Chatsonic – Unlimited Chatsonic generations, but no access to Standard or Advanced templates.
• Individual – Unlimited generations on Standard templates, 50 credits per month for Advanced templates.
• Standard – Everything in Individual + 1,000 credits per month, automated internal linking, AI keyword clusters, and improvements to Article Writer 6.0.
• Professional – Everything in Standard + 3 team members, 3,000 credits per month, AI content gap analysis, and personalized onboarding.
• Advanced – Everything in Professional + 5 team members, 6,500 credits per month, and priority support.
• Enterprise – Custom team members, custom apps, enhanced security, SSO/SAML login, personalized training, and priority support.

Writesonic’s ease of use and versatility with art and text generation, SEO, and TTS make it a great tool for those working with multimedia content.

It’s also a bit cheaper than Jasper AI, while still offering many similar features. Scalenut’s SEO offering is more robust, so I’d recommend it over Writesonic if you’re wanting to enhance your sales and marketing efforts without needing art generation or TTS.

100+ Writing Templates – In its vast bank of templates, Simplified offers more email templates than any of its competitors, including rejection emails, cold emails, and promotional emails.

AI Chat – It allows you to work with its templates, or in a chatbot style, which can be more familiar if you have experience using ChatGPT.

AI Writer – In addition to email writing, Simplified is also capable of writing blogs, essays, and articles.

Simplified AI Writer offers four paid-for plans, including a free forever tier. I’ve highlighted the costs of each of its plans below:

• Free – 5,000 free credits, access to Simplified chat, AI writer, and 80+ templates.
• Pro – Everything in Free plus 100,000 words per month, 1 seat, 1 brand book.
• Business – Everything in Pro, 600,000 words per month, 5 seats.
• Enterprise – Everything included in Business plus additional seats, generations, more brand books, and advanced features for larger teams.

For $24 per month (billed annually), you can choose to subscribe to Simplified One to access Simplified’s AI Design, Video, Writing, and Social Media tools.

Along with Writesonic and Rytr, Simplified offers a generous free plan that suits those looking to explore AI without signing up for an expensive subscription.

Like Writesonic, Simplified also offers various multimedia tools such as design, video, and social media tools. This means it’s a great option for creative teams looking for a versatile AI content generator to take care of more than just emails.

However, it lacks Scalenut’s SEO proficiency, so it is not my top recommendation for sales and marketing professionals.
