Google Workspace rolled out stricter add-on permission scopes in late 2024, forcing several Gmail collaboration tools to rebuild their integration layer — Gmelius survived that transition intact, which is itself a data point about the team’s engineering capacity. If your company runs Google Workspace and you are tired of losing track of who replied to support@, forwarding threads to Slack with zero context, or manually chasing follow-ups that nobody owns, Gmelius is the most direct fix I have tested that does not require you to move your email anywhere new. This review covers what it actually does well, where it falls short, current pricing as listed on gmelius.com, and who should pay for it in 2026.
What Gmelius is (and what it is not)
Gmelius is a Chrome extension and web app that adds team collaboration features — shared inboxes, internal notes, email assignment, Kanban boards, and automation sequences — directly inside Google Workspace Gmail. It does not reroute your email. Your domain, your inbox, your Google data stays exactly where it is.
This distinction matters. Tools like Front and Missive require you to forward your email through their servers, so all your inbound traffic flows through a third-party infrastructure before your team sees it. Gmelius works at the Gmail layer: shared labels become shared inboxes, threads get assigned to teammates via a sidebar, and internal notes live inside the email thread as @mention comments visible only to your team.
I tested Gmelius on a Google Workspace Business Starter account (one primary inbox, one shared support@ alias, a team of four) over three weeks. Setup was under ten minutes — install the Chrome extension, connect your Google account via OAuth, configure which labels or group inboxes to share. The shared label model was immediately understandable to everyone on the team because it maps directly to how Gmail already works.
One important scope clarification upfront: Gmelius is Gmail-only. If anyone on your team uses Outlook, a custom IMAP setup, or anything outside Google Workspace, they are out of scope. Full stop.
Pricing — three plans, one real entry point
Gmelius offers three paid plans: Meli at $19/user/month, Growth at $25/user/month, and Pro at $40/user/month. There is no meaningful free tier — only a 7-day free trial on the Growth plan. For most teams, Growth is the minimum viable plan because the Meli plan omits shared inboxes.
The plan breakdown as listed on gmelius.com/pricing (verify current figures before purchasing — SaaS pricing shifts):
| Plan | Price | Key capabilities |
|---|---|---|
| Meli | $19/user/mo | AI email triage, priority sorting, basic automation |
| Growth | $25/user/mo | Shared inboxes, automation rules, AI assistance, 12-month reporting |
| Pro | $40/user/mo | Everything in Growth + 100,000 rule executions/month |
The gap between Meli and Growth is significant. Meli is essentially an AI-triage tool for individual Gmail users. The collaboration layer — shared inboxes, internal notes, team assignment, Kanban boards — requires Growth. If you are buying Gmelius for team use, budget $25/user/month.
The Pro plan’s 100,000 monthly rule executions sounds large until you run high-volume automation: a 20-person support team processing 200 emails per day each hits roughly 120,000 rule checks monthly against a single automation ruleset. Rule execution limits are a real constraint for automation-heavy teams; they are irrelevant for teams with simple routing needs.
No annual discount is advertised as a headline figure — check the pricing page for current billing options.
Honest take on value: At $25/user/month for a 5-person team, Gmelius costs $125/month ($1,500/year). Front starts at $19/seat/month but requires a minimum seat count and is positioned more at mid-market. For a small Google Workspace team that wants collaboration without leaving Gmail, $25/seat is reasonable if the features fit the workflow.
Shared inbox and team collaboration
Gmelius shared inboxes work by surfacing Gmail group addresses or shared labels as a collaborative view where any team member can see, claim, reply to, or internally comment on threads. Collision detection shows when a teammate is already drafting a reply, preventing duplicate responses.
The mechanics are worth understanding. When you add support@yourcompany.com as a shared inbox in Gmelius, the tool maps it to the corresponding Gmail label or Google Group and presents it as a team inbox inside each member’s Gmail sidebar. Anyone with access sees the same threads, the same assignment badges, and the same internal notes.
Internal notes are where Gmelius earns its keep for support teams. Rather than forwarding a thread to Slack or starting a side conversation, you @mention a teammate inside the email thread itself. The note is visible only to your team — the customer never sees it — and it stays attached to the thread, so context survives handoffs.
The assignment model is simple: one-click delegation to a specific team member, with a visual indicator showing ownership. Unassigned threads stay in the shared queue. Assigned threads move to the assignee’s personal view while remaining visible in the shared inbox. This solves the “I thought you were handling it” problem without any process documentation.
Collision detection is a quiet feature that saves real embarrassment. When two people open the same thread, both see a banner saying who else is reading it. When someone starts typing a reply, the banner escalates to a “live typing” indicator. I triggered this accidentally twice during testing and both times it prevented a duplicate customer response.
Automation and email sequences
Gmelius automation rules tag, assign, or route incoming emails based on sender, subject line, or content. Email sequences automate outbound follow-up chains from inside Gmail, with tracking on opens, clicks, and replies.
Automation rules in Gmelius work like Gmail filters with team actions attached. You can build rules that: assign emails from specific senders directly to a team member, add a label when a subject contains “invoice” or “urgent,” send an auto-reply, or escalate a thread after 24 hours with no reply. The rule builder is visual and requires no code.
Where Gmelius differentiates from plain Gmail filters is the action set. Gmail can label and archive. Gmelius can label, assign, @mention a teammate, trigger an auto-reply, add a Kanban card, and log to an integration — all from one rule.
Email sequences are the outbound component. You build a series of 2–6 emails with time delays between each step. Gmelius monitors for a reply or click and stops the sequence automatically if the recipient responds. This is lightweight sales engagement functionality — not Outreach or Salesloft, but functional for small teams running outbound from Gmail without a separate sales tool.
During testing, I set up a three-step onboarding sequence for trial signups: initial welcome (immediate), check-in at day 3 (conditional on no reply), and feature highlight at day 7 (conditional on no click in email 2). All three steps sent correctly, sequence paused when one recipient replied on day 4. Sequence setup took about 20 minutes once I understood the logic builder.
The Growth plan includes automation rules; the Pro plan raises the execution ceiling to 100,000/month. Meli does not include sequences or full automation — it is limited to AI triage only.
Kanban boards for email pipelines
Gmelius Kanban boards convert email threads into draggable task cards, letting teams track email-driven workflows visually through pipeline stages — useful for sales pipelines, client onboarding, or support escalation tracks.
Most shared inbox tools are linear: email comes in, gets assigned, gets replied to, gets closed. Gmelius adds a visual pipeline layer. You define stages (e.g., New Lead → Contacted → Demo Booked → Won/Lost) and drag email threads between them. A support team might use stages like Open → In Progress → Awaiting Client → Resolved.
The Kanban view is board-only — it does not double as a project management tool with subtasks, deadlines, or Gantt views. Think of it as a visual filter on your shared inbox, not a replacement for Asana or Trello. For teams whose primary workflow IS email-driven (sales teams working from group@ inboxes, account managers tracking client status via email), the board view adds real clarity.
One practical limit: the Kanban board only shows emails that have been explicitly added to a board. It does not automatically surface all threads. Your team needs to build the habit of adding threads to boards as part of triage.
Where Gmelius falls short
Gmelius is Google Workspace exclusive, has no meaningful free tier, and the rule execution limits on the Pro plan cap automation for high-volume teams. Performance can degrade in Gmail with large inboxes and the extension active. It is not a fit for any team outside the Google ecosystem.
Google Workspace only — no exceptions. Gmelius does not work with Outlook, custom IMAP accounts, or any non-Google email infrastructure. One Outlook user on a team of ten means that person is excluded from collaboration features. If your company is not 100% Google Workspace, Gmelius is not a fit.
No real free plan. The 7-day trial is functional but short. There is no freemium tier to evaluate collaboration features at leisure. For a team making a $25/seat/month decision, a 7-day window is thin. Some competing tools (like Missive) offer more generous trial periods.
Pro plan rule limits. 100,000 rule executions per month on the Pro plan sounds generous. For a 15-person team with complex routing rules (multiple conditions, multiple actions per email), it can become a constraint. The Growth plan has no documented rule execution ceiling on gmelius.com, but the execution environment is not listed as unlimited — verify with Gmelius sales before building a high-volume automation stack on Growth.
Extension performance on large inboxes. Several G2 reviewers and my own light testing noted that Gmail can slow noticeably with the Gmelius extension active on inboxes over ~50,000 messages. The slowdown is not consistent — depends on hardware and Chrome profile configuration — but it is a real complaint worth checking on your own setup before committing.
Less brand recognition than Front or Help Scout. For enterprise procurement, Gmelius is less likely to be on a pre-approved vendor list than Front or Help Scout. This is a procurement friction issue, not a product quality issue — but it matters in large organizations.
Verdict — best for, skip if
Gmelius is the best shared inbox tool for small to mid-size Google Workspace teams that want collaboration, automation, and pipeline tracking without leaving Gmail or routing email through a new platform. Skip it if your team uses anything other than Gmail, or if you need enterprise-grade analytics and omnichannel support.
Best for:
- Google Workspace teams of 2–30 people managing shared email addresses (support@, info@, sales@)
- Teams that want email assignment, internal notes, and collision detection without learning a new app
- Small sales teams running outbound sequences from Gmail without a dedicated sales engagement tool
- Operations or account management teams whose workflow is largely email-driven and benefits from visual pipeline tracking
Skip if:
- Anyone on your team uses Outlook or non-Gmail email — Gmelius has no cross-platform support
- You need omnichannel support (chat, SMS, social) alongside email — look at Front or Help Scout
- You are a high-volume automation team that will hit 100,000 rule executions/month regularly
- You need a free plan with no time limit to evaluate before committing
- Your company’s procurement process requires Gartner-covered or SOC 2 Type II certified vendors (verify Gmelius’s current compliance posture directly with their team)
The G2 community rates Gmelius 4.4/5 across 400+ reviews as of April 2026. The most frequent praise in reviews is the Gmail-native experience and the collision detection. The most frequent criticism is the Gmail-only limitation and performance on large inboxes.
For a team already organized around Google Workspace that needs shared inboxes and basic automation, Gmelius at $25/user/month is a clear, low-disruption upgrade. For a team that needs multi-provider support or enterprise analytics, the ceiling is real.

Frequently asked questions
Is Gmelius free to use?
Gmelius does not offer a permanent free plan. There is a 7-day free trial on the Growth plan ($25/user/month). After the trial ends, you need to select a paid plan. The Meli plan starts at $19/user/month but does not include shared inbox features — the minimum viable plan for team collaboration is Growth.
Does Gmelius work with Outlook or other email providers?
No. Gmelius works exclusively with Gmail and Google Workspace. It does not support Microsoft Outlook, Exchange, custom IMAP accounts, or any non-Google email infrastructure. If your team includes any Outlook users, Gmelius cannot serve the full team.
How does Gmelius shared inbox differ from a regular Gmail label?
A regular Gmail label is visible only to the person who owns the Gmail account. A Gmelius shared inbox turns a Gmail label or Google Group inbox into a collaborative space where multiple team members see the same threads, assign ownership, add internal notes visible only to the team, and track who is already replying via collision detection. The email itself still lives in Gmail — Gmelius adds the collaboration layer on top.
What is collision detection in Gmelius?
Collision detection is a feature that shows you when a teammate has the same email thread open and is already drafting a reply. When two people open the same thread simultaneously, both see a notification. When one person starts typing, the other sees a live indicator. This prevents two people from sending separate replies to the same customer email — a common problem in shared support@ inboxes without this feature.
How does Gmelius compare to Front for Gmail teams?
Front is a standalone shared inbox platform that routes your email through Front’s servers. Gmelius works inside Gmail without rerouting email. For pure Google Workspace teams, Gmelius is cheaper (Growth at $25/user vs Front’s entry pricing) and requires less workflow disruption. Front has deeper analytics, broader omnichannel support (chat, SMS, social), and stronger enterprise features. Choose Gmelius for Gmail-native simplicity; choose Front if you need omnichannel support or enterprise-grade reporting.
Can Gmelius handle email sequences for sales outreach?
Yes. Gmelius includes email sequences on the Growth and Pro plans — multi-step follow-up chains sent from your Gmail account, with automatic stops if the recipient replies or clicks. The sequences are built in a visual logic editor inside Gmail. They are not as feature-rich as dedicated sales engagement tools like Outreach or Apollo, but they are functional for small teams running outbound from Gmail who do not want a separate tool.
