Mailopoly

Cleanbox - The Intelligent Inbox Filter

Mailopoly's core intelligence, Cleanbox, automatically learns what matters to you from day one. It surgically separates critical emails from noise, reducing your inbox volume and notifications by over 50%. No complex rules to set up—it just works. It surfaces priorities so you're only alerted to what's truly important, turning your inbox from a distracting notification center into a curated list of actionable items. One tap is all it takes to teach it your preferences, making it smarter and more accurate over time.

Poly - Your Built-In AI Life Assistant

Poly isn't a bolted-on chatbot; it's your integrated executive assistant that knows everything about your inbox, schedule, and priorities. You can ask Poly anything in plain English: "What do I need to pay this week?" "Summarize emails from my accountant." "What are my upcoming flights?" It pulls information from across your connected accounts to give you instant, comprehensive answers, helping you get things done instead of just managing messages. It's like having a personal EA for all your life admin.

AI-Powered Reply Drafting & Information Extraction

Stop typing and start deciding. Mailopoly's AI reads your emails and instantly extracts all crucial information—invoice amounts, booking details, delivery dates, attachments—so you know everything at a glance without opening a single email. Then, it drafts full, context-aware email replies in your own unique voice and tone. You get multiple suggestions, can edit in seconds, and send with confidence, saving massive amounts of time on personal, work, and side-hustle communication.

Complete Life Admin Toolkit

Mailopoly is more than email; it's a full life management suite. It includes an instant one-click unsubscriber that actually works, an email tracker showing who opened your messages and where, and a built-in task manager that tracks deliveries and shipments with a full timeline. The event manager lets you send custom invitations and track RSVPs effortlessly. It automatically manages your finances and events mentioned in emails, centralizing scattered life admin into one powerful, secure app.

This is the core magic. Unlike AI that resets with every chat, SureThing has a long-term memory that builds over time. It remembers your communication style, your priorities, your recurring tasks, and the nuances of your ongoing projects. The longer you work together, the smarter and more personalized its assistance becomes, requiring less explanation from you.

SureThing.io FAQ

How is SureThing different from ChatGPT or other AI chatbots?

ChatGPT is a reactive tool—you ask, it answers, and the context resets. SureThing is a proactive, autonomous agent. It works continuously in the background, takes initiative based on your goals, and possesses a permanent memory of your work and preferences. It's designed for ongoing action and delegation, not just conversation.

What does "Google CASA Tier 2 Compliant" mean?

Google's CASA (Cloud Application Security Assessment) framework is a rigorous security standard. Tier 2 compliance signifies that SureThing has undergone and passed an independent, in-depth assessment of its security posture, data protection practices, and infrastructure. It's a strong validation of our enterprise-ready security for Google Workspace users.

Can I trust SureThing with sensitive emails and data?

Absolutely. Security is our foundation. Beyond Google CASA Tier 2, we are SOC 2 Type II certified, which is an industry-standard audit for service organizations covering security, availability, processing integrity, confidentiality, and privacy. Your data is encrypted and handled with the highest standards of trust and compliance.

How does SureThing "learn my voice" for communication?

SureThing's persistent memory analyzes your past written communications—your tone, phrasing, formality level, and common expressions. Over time, it builds a nuanced model of your unique style. When drafting emails or messages on your behalf, it applies this model to generate text that sounds authentically like you, maintaining your personal or professional brand.
