2. Description of Service

Messybox provides an AI-powered email productivity platform that includes smart inbox sorting, AI-drafted replies, follow-up nudges, and related features. The Service integrates with third-party email providers (such as Gmail and Microsoft 365) to process and organize your email.

We reserve the right to modify, suspend, or discontinue any aspect of the Service at any time, with or without notice. We will make reasonable efforts to notify users of material changes in advance.

7. Free Plan

The Free plan is provided at no cost and includes limited features as described on our pricing page. We reserve the right to modify the features or availability of the Free plan at any time. The Free plan is provided "as-is" without any service level guarantees.

8. Intellectual Property
