questions about Monsteria
What is Monsteria?
Monsteria is the developer platform for building email AI agents. We handle the complex infrastructure so you can focus on creating great email interactions.
How is Monsteria different from other email AI services?
Monsteria focuses on developers. Giving developers modular, simple, & robust tooling to build any email AI application imaginable. Monsteria is one of the first platforms to offer a unified API for building email AI agents that can interact with multiple email providers such as Gmail and Outlook. This allows developers to create AI agents that can seamlessly send, receive, and respond to emails across different platforms without having to deal with the complexities of each individual email service.
Couldn’t I build this myself and save money?
You could — but there are good reasons for not doing so. Writing a great email AI application from scratch is a fairly challenging task. Most of these challenges are not apparent until you face them, then you realize you are 3 weeks into a rabbit hole that may take months to properly solve out of. Think of Monsteria as hiring a software engineering team for this hard problem, while you focus on what uniquely generates value for your email AI application.
Do you support white-labeling?
Yes, Monsteria is an API-first platform. This means you can bake it in your product without using Monsteria branding.
Is it going to be hard to set up?
No — in fact, the setup could not be easier: Web Dashboard: It can take minutes to get up & running with our dashboard. API: You can start sending and receiving emails with as little as 2 API calls. For more advanced features like function calling, you will have to set up a webhook URL to receive and respond to notifications.
Are you compliant with HIPAA, SOC 2, and GDPR?
Yes, we take compliance seriously. Monsteria is currently working towards the following certifications: HIPAA compliant for healthcare applications SOC 2 Type II certified GDPR compliant for handling EU data
How do you handle PII and PHI securely?
We implement multiple layers of security for PII and PHI: End-to-end encryption for all data in transit Secure storage with encryption at rest Strict access controls and audit logging Regular security assessments and penetration testing Data minimization practices Secure data deletion protocols All data handling practices are documented in our security policies and compliance frameworks.
