Persistent, Adaptive Memory
This is SureThing's core superpower. It builds a comprehensive understanding of you over time, remembering your communication style, your priorities for different projects, and your preferences for scheduling.

Frequently Asked Questions
Postal FAQ
What is a virtual mailbox?
A virtual mailbox is a service that provides you with a real physical street address. When your mail arrives at that address, the service provider (like Postal) securely scans the exterior and interior of each piece and uploads it to a private, online dashboard for you to access from anywhere. You can then read, download, forward, or request the shredding of your physical mail digitally. Postal enhances this with AI summaries, deadline tracking, and integrated compliance support.
How does Postal handle check deposits?
When a paper check arrives in your Postal mailbox, the team scans it just like any other piece of mail. Within your online dashboard, you will see the scanned check and can request a deposit. Postal then works with your banking partner to process the deposit electronically, typically through secure lockbox services or remote deposit capture (RDC), getting the funds into your account without you ever needing to touch the physical check.
What does Postal's AI actually do?
Postal's AI acts as your smart mail assistant. It reads and analyzes the content of your scanned mail to save you time. Its key actions include: generating concise summaries of long letters or statements, identifying and flagging urgent correspondence (like legal documents), automatically extracting key data points such as due dates and invoice amounts, and recommending actions (e.g., "File this by July 15"). You can also ask it questions about your mail for deeper insights.
Is Postal secure and compliant?
Yes, absolutely. Security and compliance are foundational to Postal's service. The platform is built to meet SOC 2 Type II standards, which is a rigorous audit for data security, and is also designed to comply with HIPAA regulations for handling protected health information. Your mail is processed in their own secure facilities, not outsourced, ensuring your sensitive business and client data is protected with the highest standards of privacy and security.
SureThing.io FAQ
How is SureThing different from a standard AI chatbot?
Standard chatbots are reactive—they only respond when you ask a question. SureThing is proactive and autonomous. It takes initiative based on its understanding of your work and goals. Furthermore, its persistent memory means it learns and remembers your context permanently, unlike chatbots that start fresh with each conversation.
What does "Google CASA Tier 2 Compliant" mean?
Google's Cloud Application Security Assessment (CASA) framework evaluates the security of applications that integrate with Google Workspace. Tier 2 compliance is a rigorous level that indicates SureThing has undergone a thorough independent security review, giving you confidence that it handles your Google-connected data with a high standard of protection.
Can I control what SureThing does on my behalf?
Absolutely. You maintain full oversight. SureThing is designed to suggest actions and draft communications for your review before sending. You can approve, edit, or reject anything. Over time, as it learns your preferences, it may automate more routine tasks, but you always have the final say and can adjust its permissions.
How does SureThing learn my "voice" for communication?
SureThing analyzes your past written communications—emails, messages, etc.—to understand your tone, formality, common phrases, and style. When it drafts a reply or message, it mimics these patterns. You can also provide direct feedback ("make this more casual" or "sound more enthusiastic"), which it remembers and applies to future drafts.
