The 6 best free AI email writer tools I tested in 2026

Writing emails can be a time-consuming task. Finding the right words for follow-ups or cold outreach can be challenging. AI email writers can generate a clear, polished draft in seconds, saving time and overcoming writer's block. This guide reviews some of the top free options to determine which ones offer the most value. However, effective emails require valuable content. A tool like the eesel AI blog writer addresses this by helping create content that makes emails worth opening.

What is an AI email writer?

An AI email writer is an intelligent assistant that uses artificial intelligence to compose emails. Users provide a simple prompt, such as "write a follow-up to a new lead," and the tool generates a complete draft. The underlying technology analyzes the request to determine the required content and tone. Key benefits include significant time savings, consistent grammar and tone, and a solid starting point for any email correspondence.

How we chose the best free AI email writers

To compile this list, we established specific criteria to ensure each recommended tool provides genuine value without requiring a credit card upfront.

• Truly free plan: The tool must offer a forever-free plan, not a limited-time trial. The free version needs to be functional for real-world tasks.
• High-quality output: The AI-generated text must be coherent, contextually appropriate, and sound human-written with minimal editing required.
• User-friendly interface: Tools were selected for their intuitive design and ease of use, allowing users to start immediately without a steep learning curve.
• Meaningful free features: The free plan needed to include core features, such as tone adjustment, to provide a comprehensive user experience.

The eesel AI blog writer offers a different approach. It focuses on solving a core challenge for email marketers: creating valuable content to send. It acts as a content engine, turning a single keyword into a full, SEO-friendly blog post. This is the same tool used at eesel AI to grow organic traffic from 700 to 750,000 daily impressions. The platform also has an AI Email Writer that learns from past emails to write replies in a brand's voice.

• Pros: It solves the "what do I even send?" problem by creating the content for your newsletters and campaigns. The articles are ready to publish and come with assets like AI-generated images and real Reddit quotes.
• Cons: It's built for generating long-form content, so it's not the right fit if you just need a quick tool for dashing off daily replies.
• Pricing: You can generate your first blog free. After that, paid plans start at $99 for 50 blog posts.

2. Mailmeteor

Mailmeteor is an AI assistant that integrates directly into your inbox and is designed for sending personalized emails at scale. It's used by over 7 million people and is recognized by Google. Its mail merge feature allows you to send customized campaigns straight from a Google Sheet. It is also built with privacy in mind, sending emails without needing to read your inbox.

• Pros: The free plan is quite generous, letting you send up to 50 emails a day. It's straightforward and respects your privacy.

• Pricing: There's a free plan. Paid plans start at $4.99 per month.

3. QuillBot

QuillBot is a comprehensive writing toolkit rather than just a text generator. It includes eight different tools, such as its well-known Paraphraser, Grammar Checker, and Summarizer.
