Privacy Policy

1. Introduction

This Privacy Policy describes how Clustox LLC, doing business as inboxwarm.ai ("inboxwarm.ai," "we," "our," or "us"), collects, uses, stores, and protects information about you when you visit our website at inboxwarm.ai (the "Site") or use our email inbox warmup platform and associated services (collectively, the "Services"). inboxwarm.ai is operated by Clustox LLC, a Delaware limited liability company, with its registered address at 8 The Green, STE A, Dover, DE 19901, United States.

Our Services help businesses and individuals improve email deliverability by gradually building sender reputation through a controlled, automated warmup process. This involves connecting to your email account and sending and receiving warmup emails on your behalf, strictly within the scope you authorize. We do not read, analyze, or process the content of non-warmup emails in your inbox.

Please read this Privacy Policy carefully before using the Services. By accessing or using the Services, you acknowledge that you have read, understood, and agreed to this Privacy Policy. If you do not agree, please discontinue use of the Services. Your use of the Services is also governed by our Terms of Use, which are incorporated herein by reference.

2. Information We Collect

We collect information in three main categories:

2a. Personal Data

When you register for an account, subscribe to a plan, or contact us, we collect personal data you provide directly, including:

  • Full name
  • Email address
  • Company name and role (if provided)
  • Phone number (if provided)
  • Billing information and billing address, payment card processing is handled exclusively by Stripe, Inc., and we do not store full card numbers on our systems
  • Connected email account details, including credentials required to access your inbox for warmup purposes, credentials are stored in encrypted form and used solely for providing the Service
  • Account credentials, including hashed passwords
  • Any other information you voluntarily submit through support requests, surveys, or direct communications

2b. Usage Data

When you use the Services, we automatically collect technical and behavioral data to operate, maintain, and improve the platform, including:

  • IP addresses and approximate geographic location derived from IP
  • Browser type, version, and language preferences
  • Pages visited, features accessed, and actions taken within the platform
  • Date, time, and duration of sessions
  • Referring URLs and navigation paths
  • Error logs and diagnostic data
  • Email warmup campaign performance metrics (e.g., delivery rates, open rates, reply rates, bounce rates, and spam complaint rates) associated with your account

2c. Email Account Data

To deliver the Service, we access your connected email account(s) (such as Gmail, Outlook, or custom SMTP providers) solely for the purpose of sending and receiving warmup emails as configured by your warmup schedule. This access is strictly limited to warmup activities. We do not read, store, analyze, or process the content of non-warmup emails in your inbox.

Warmup emails sent through the Service may be generated dynamically using automated tools, including AI-based content generation services, to simulate realistic communication patterns. These tools operate on anonymized or synthetic data. Your email content and personal data are never used to train AI models.

As part of the warmup process, the Service uses a pool of system-operated email accounts to send simulated replies to your inbox, creating natural conversation threads. These pool accounts are operated under strict privacy and security controls.

2d. Cookies & Tracking Technologies

We use cookies, web beacons, pixels, and similar tracking technologies on the Site. The categories we use are:
