Gmelius Review — Honest Pros, Cons & Pricing (2026)

Category: Shared inbox and workflow automation for Gmail teams

Also known as: gmelius.

Overview

Gmelius turns Gmail into a collaborative workspace for teams. It adds shared inboxes, email delegation, shared labels, SLA tracking, and Kanban boards directly inside Gmail. For cold email operations, Gmelius solves a specific problem: managing replies from cold email campaigns across a team. When your campaigns generate 20 to 50 replies per day, you need a system for assigning replies to specific team members, tracking response times, and making sure nothing falls through the cracks. Gmelius handles this without requiring your team to leave Gmail. It is not a cold email sending tool. It sits downstream of your sending platform and helps you manage the conversations that cold email generates.
