About

What is Inboxs

Inboxs pulls X/Twitter and Instagram DMs into one inbox where you can tag contacts, add personal notes, set follow-up reminders, and fire off quick replies without switching between apps. It's built for solo operators and small teams — founders running their own pipeline, SDRs or BDRs working social leads — who treat DMs as a real sales channel rather than a side inbox. The standout capability is filtering and exporting tagged contacts, which lets you segment conversations by deal stage or topic and act on them in bulk rather than scrolling endlessly. Where it stops being a fit: Inboxs covers only X/Twitter and Instagram, so if your prospects live on LinkedIn or email, you'll need separate tooling for those channels.

Our verdict

Vanderbuild take

For founders and SDRs who close deals through X/Twitter or Instagram DMs, Inboxs is a focused CRM that does one thing — keeps those conversations organized and moving — without trying to be a full sales suite. On the agentic readiness front, this is UI-only with no API available; you can't drive it from an agent or plug it into an MCP layer without scraping, so don't plan any workflow automation beyond what's built into the product itself. At $35/month flat with a 7-day free trial and no credit card required, the risk to test is low. The honest limitation is channel coverage: if your ICP isn't reachable on X or Instagram, this tool has nothing to offer you.
