Full Review
Overview
Mailbutler is a lightweight email productivity extension that adds smart features directly into Apple Mail, Gmail, and Outlook without replacing your email client. Founded in 2015 in Berlin, Germany, Mailbutler takes an add-on approach — enhancing your existing inbox with AI drafting, email tracking, scheduling, and task management. This makes it particularly valuable for Apple Mail users, who are often underserved by standalone email productivity tools.
Key Strengths
Mailbutler's AI Smart Assistant, powered by OpenAI, can write, rewrite, and summarize emails, extract tasks from messages, and suggest responses — all from within your compose window. The advanced email tracking shows when, where, and how many times your emails and links are opened. Send Later scheduling lets you compose now and deliver at optimal times. The built-in task and note system turns emails into actionable items without leaving your inbox. Email signatures are professionally customizable with branding options.
Pricing Analysis
Mailbutler offers a free Essential plan with basic tracking and limited AI. The Professional plan at $8.95/month adds advanced tracking, smart scheduling, and unlimited templates. The Smart plan at $14.95/month unlocks the full AI assistant, task management, and signature branding. Business teams pay $32.95/month per user for collaboration tools and shared inbox support. A 14-day free trial with full access is available, and annual billing saves approximately 20%. Additional AI credits can be purchased for heavy users.
Who Is It Best For?
Mailbutler is ideal for professionals who love their current email client (especially Apple Mail users) but want to add AI and productivity features on top. Sales professionals benefit from email tracking and scheduling, while project managers appreciate the task extraction and note features. It is less suitable for teams needing full shared inbox functionality or users who want a completely new email experience.
The Bottom Line
Mailbutler is the best email productivity add-on for users who want to enhance rather than replace their inbox. The AI features are genuinely useful for drafting and summarizing, and the tracking capabilities rival standalone tools. The main limitations are the lack of a mobile-first experience and occasional bugs reported by Apple Mail users. For its price point, Mailbutler delivers excellent value as an inbox enhancer.
