Overview

Inboxapp is an early-access CRM that consolidates conversations from X (including XChat encrypted DMs), LinkedIn, and other channels into a single shared inbox. It remembers contacts, tags conversations, and tracks follow-ups. Setup requires installing a Chrome extension and linking accounts. Teams can share inboxes and manage pipelines. A BYOK (Bring Your Own Key) X API integration allows higher daily DM limits by connecting a pay-per-use X developer app. The platform supports API access for programmatic inbox and message management.

Cons & Tradeoffs
