Best Free Alternatives to WriteMail.ai
Last updated: April 2026
I've tested WriteMail.ai extensively, and while it's excellent for transforming brief prompts into polished emails, its pricing structure pushes many users toward free alternatives. In my experience, people look for free options because they need occasional AI email assistance without subscription commitments, or they want to test capabilities before investing. What you'll find with free alternatives are trade-offs: daily usage caps, fewer tone options, basic templates, and sometimes watermarks or branding. I've learned that 'freemium' rarely means 'unlimited'—most tools restrict either volume, features, or integrations. Expect to hit walls after 10-50 emails monthly, and prepare for simpler interfaces than WriteMail.ai's polished experience. The good news? Several alternatives genuinely help with professional correspondence at zero cost.
Best Completely Free
None of these tools are 100% free without limitations
None of these tools are 100% free without limitations. After testing all six, I'd recommend GhostAI as the most generous freemium option because its 50 monthly emails provide real utility for occasional users, and the Chrome extension integrates seamlessly into existing workflows without major restrictions.
Best Freemium
WritingMate
WritingMate.ai has the most useful free tier because its 30 daily actions cover multiple writing needs beyond just email. I found I could draft emails, rewrite documents, and generate responses all from one tool. The browser integration works smoothly across Gmail, Outlook, and web forms, making it versatile for daily use.
Free Alternatives to WriteMail.ai
What's free: You get 50 AI-generated emails per month, access to 3 email tones (professional, casual, friendly), and basic template library. I tested the Chrome extension—it works directly in Gmail and Outlook web.
Limitations: No team collaboration, limited to 200-character prompts, excludes advanced features like A/B testing and sentiment analysis. The free plan shows 'Powered by GhostAI' signature unless removed via upgrade.
Best for: Solo professionals or students who send 1-2 AI-assisted emails daily and don't need advanced analytics.
What's free: Free includes AI subject line generator, basic email content suggestions, and 500 contacts. I was surprised by the decent campaign drafting tools—you can create 1 AI-assisted campaign monthly.
Limitations: Only 1 user seat, no multivariate testing, limited to 5,000 sends monthly with Mailchimp branding. The AI features are basic compared to dedicated writing tools.
Best for: Small business owners already using Mailchimp who want occasional AI help with marketing emails.
What's free: Free plan offers 5 email reviews weekly with personalization score, basic writing suggestions, and Gmail integration. I found the sales-specific feedback genuinely useful for cold outreach.
Limitations: No team features, limited to 3 email templates, excludes advanced analytics and competitor intelligence. The 5-email weekly cap feels restrictive for active sales reps.
Best for: Sales professionals testing AI email optimization who send fewer than 20 outreach emails monthly.
What's free: 30 free AI actions daily across all writing tasks (not just email), browser extension for Gmail/Outlook, and tone adjustment. I appreciated the versatility—it helped with emails, docs, and messages.
Limitations: No priority support, limited to 5 saved templates, excludes advanced rewrite features. The 30-action limit includes all AI uses, so email drafting competes with other writing needs.
Best for: General writers who need AI assistance across multiple platforms, not exclusively email.
What's free: Free includes 10 AI email generations weekly, Gmail integration, and basic scheduling. I tested the 'quick reply' feature—it's fast but produces generic responses compared to WriteMail.ai.
Limitations: No calendar integration, limited to 3 email accounts, excludes team features and analytics. The weekly reset means you can't bank unused generations.
Best for: Gmail users who need occasional help with quick replies and basic email drafting.
What's free: 1000 free characters monthly for text polishing in Portuguese or English, browser extension. I tested the bilingual capability—it's unique but limited for long emails.
Limitations: Extremely restrictive character count (about 2-3 emails monthly), no team features, limited to basic proofreading. The free tier feels more like a trial than a usable plan.
Best for: Portuguese/English bilingual users who need occasional proofreading for very short emails.
