Inbox Optimiz privacy policy

Last updated 30 October 2026

This policy explains what Inbox Optimiz (www.inboxoptimiz.com) and the Inbox Optimiz Android app collect, why, and the choices you have. Questions go to [email protected].

What we collect

• Account details: your email address, workspace or company name and a user ID.
• What you check: domains, email content and test results you run through our deliverability tools, and the history saved to your account.
• Seed mailboxes: if you connect test mailboxes, their address, mail server and login details, so we can check where your test emails land. You can remove them in Settings at any time.
• Plan and payment records: which plan you have and when it renews. Payments are made on our website through Stripe.
• Email: we send account emails and test messages through Resend.
• Usage data: our website uses Google Analytics to count visits. Basic technical data such as device type and server logs keeps the service running and secure.

How we use it

• To run the service you asked for and keep your history.
• To manage your plan, if you have one.
• To answer support requests and keep the service secure and working.

We do not sell your data, use it for advertising, or share it with anyone except the service providers below.
