Gmelius Review 2026: Features, Pricing & Honest Verdict
Gmelius is a Gmail-native collaboration platform. It bundles shared inboxes, sequences, kanban boards, and automation into one Chrome extension. No separate app to learn.
The trade-offs: Gmail-only (no Outlook), per-user pricing scales fast, and the all-in-one approach means no single feature is best-in-class.
Verdict: Solid pick for SMB Gmail-first teams that want shared inboxes plus sequences in one tool. Skip it if you only need shared inboxes (use Hiver), only need sequences (use Mixmax), use Outlook (use Yesware), or send high-volume cold email (use Instantly).
What is Gmelius?
Gmelius is a team email collaboration tool that lives inside Gmail. Built by a Switzerland-based team, it's used primarily by SMB and mid-market teams. It adds shared inboxes, shared labels, sequences, kanban boards built from emails, automation rules, and integrations with Slack, Trello, and HubSpot directly to Gmail's interface.
Think of it as a hybrid between a shared-inbox tool (like Hiver or Front), a Gmail CRM (like Streak), and a sales engagement tool (like Mixmax). It does all three reasonably well, but a focused tool will do any one of them better.
Key features
- Shared Gmail inboxes: Convert any Gmail label or alias (support@, sales@) into a team-managed inbox with assignment, statuses, internal notes, and visibility controls.
- Shared labels and drafts: Collaborate on email threads in real-time with shared drafts, mentions (@), and shared labels visible across the team.
- Email sequences: Multi-step automated outreach with reply detection that auto-stops the sequence when a recipient responds.
- Kanban boards: Turn email threads into kanban-style cards for tracking deals, hiring, projects, or any process tied to email.
- Email templates: Personal and shared template libraries with merge variables and team approval flows on higher tiers.
- Automation rules: If-this-then-that automation for inbox actions (auto-assign by sender, auto-tag by subject, auto-route based on rules).
- Mail merge: Send personalized email campaigns from Google Sheets with tracking and follow-ups.
- Meeting scheduler: Embed available time slots in emails so recipients can book without leaving Gmail.
- Integrations: Native two-way sync with Slack, Trello, Asana, HubSpot, Salesforce, Pipedrive, and Zapier (mostly on Pro).
- Reporting: Team analytics on response times, SLA compliance, sequence performance, and inbox load.

Pros
- Lives in Gmail. Zero context-switching. Shared inboxes, sequences, kanban, and automation all sit inside your normal inbox.
- True all-in-one. Replaces Hiver + Streak + Mixmax for teams that want one tool instead of three. Useful for SMBs that don't want to juggle subscriptions.
- Strong shared inbox features. Assignment, statuses, internal notes, mentions, and SLA tracking are properly thought through, not bolted on.
- Slack and Trello integrations. Native two-way sync (not just notifications) is rare in Gmail tools and genuinely useful for ops teams.
- Automation flexibility. Rule builder is more powerful than Streak's automations; useful for routing support tickets or auto-replying based on triggers.
- Privacy-focused company. EU-based (Switzerland), GDPR-friendly, with a generally good security posture.
Cons
- Gmail-only. No Outlook support. Mixed or Outlook teams need Yesware.
- Per-user pricing scales fast. A 10-person team on Growth = ~$240/month. Scaling to 25+ users gets pricey.
- Jack-of-all-trades, master of none. Hiver's shared inboxes are simpler. Streak's pipelines are cleaner. Mixmax's sequences and scheduler are more refined. Gmelius covers all three but doesn't lead any.
- Free plan is solo-only. Useful for testing personal features, but you can't try team features (the actual reason most people consider Gmelius) without paying.
- Setup complexity for shared inboxes. Connecting team aliases, configuring rules, and training people takes time. Not 5-minute onboarding.
- Gmail sending limits apply. Sequences send through your Gmail account, capping at ~500 (free) to ~2,000 (Workspace) emails/day. No inbox rotation for cold email volume.
- No built-in contact database. You need a separate prospecting tool like Apollo.io or Hunter.io.
- Performance with large pipelines. Gmail can slow noticeably when boards have hundreds of cards or when shared inboxes carry heavy volume.
Who is Gmelius best for?
- Small-to-mid-sized Gmail-first teams (under 20 users) wanting one tool instead of three
- Support and ops teams that need shared inboxes plus light automation
- Teams using Slack or Trello as their hub, the integrations are unusually deep
- Account managers and customer success who handle shared customer email accounts
- Privacy-conscious EU teams that value a Switzerland-based vendor
Who should look elsewhere?
- Outlook users: Gmelius is Gmail-only. Use Yesware for the closest cross-client feature set.
- Pure shared-inbox teams: Hiver is more focused if you don't need sequences or kanban. Front is a strong standalone option supporting Gmail, Outlook, and SMTP.
- Pure CRM users: Streak has cleaner pipelines and a usable free tier.
- Pure sales engagement: Mixmax has stronger sequences, the best inline scheduler, and Salesforce sync.
- High-volume cold emailers: Gmail's daily limits cap you at ~500 sends/day. Use Instantly ($30/mo) or QuickMail ($49/mo) with inbox rotation.
- Link building teams: Gmelius isn't designed for link building. MentionAgent ($99/mo flat) automates the full workflow.
Alternatives worth considering
| Tool | Starting Price | Best For |

Your team of 10 reps uses Outlook, not Gmail. Which tool gives you a Gmelius-style feature set?
Right! Gmelius is Gmail-only. Yesware works in both Gmail and Outlook with similar tracking, sequences, and templates. Streak is also Gmail-only.
Gmelius doesn't support Outlook at any tier. Yesware covers both clients. Streak is also Gmail-only.
You send 2,000 cold emails per week to prospects. Why isn't Gmelius the right tool?
Right! Gmelius sends through your Gmail account, which has a ~500 email/day limit (free) or ~2,000/day (Workspace). For sustained 2,000/week you want inbox rotation across multiple sending accounts, use Instantly or QuickMail.
Gmelius has sequences and follow-ups. The issue is Gmail's daily sending limit. High-volume cold email needs inbox rotation across multiple accounts, which Gmelius doesn't do.
You're a solo link builder who wants to stop managing campaigns, templates, and sequences. Which tool fits?
Correct! MentionAgent automates the full link building workflow, prospect finding, contact lookup, email writing, and follow-ups. Gmelius and Yesware still require you to build and run campaigns manually.
Gmelius and Yesware are productivity layers on your inbox, you still manage campaigns manually. MentionAgent ($99/mo flat) automates the entire link building workflow end-to-end.
Outreach that runs itself
MentionAgent finds relevant blogs, looks up contacts, writes personalized pitches, and follows up. You just approve the emails. No per-user pricing, no shared inboxes to manage, no campaigns to build.

Frequently asked questions
Is Gmelius legit?
Yes. Gmelius is a Switzerland-based company that has been building Gmail collaboration tools for years. It's used primarily by SMB and mid-market teams for shared inboxes, sequences, and team automation.
What is Gmelius best for?
Small-to-mid-sized Gmail-first teams that want shared inboxes, sequences, and basic automation in one Chrome extension instead of stitching together several specialized tools.
What are the downsides of Gmelius?
Gmail-only (no Outlook), per-user pricing scales fast, the all-in-one approach means no single feature is best-in-class, and Gmail's sending limits cap cold email volume.
Is there a better alternative to Gmelius?
Does Gmelius work on mobile?
Partially. The Chrome extension runs in desktop Gmail, so most features are desktop-only. Gmelius has iOS and Android apps for reading and replying inside shared inboxes and sequences, but campaign and automation setup happens on desktop.
Is Gmelius a Chrome extension?
Yes. It installs as a Chrome extension that sits on top of Gmail. Also works in Edge and Brave (Chromium-based). Limited support in Safari and Firefox.
Can Gmelius replace a CRM?
For lightweight needs, yes. Kanban boards and shared inboxes work for basic deal tracking or hiring pipelines. For real CRM needs (custom fields, reporting, opportunity stages), use HubSpot or Salesforce, optionally with Streak for Gmail-side tracking.
Does Gmelius integrate with Slack and Trello?
Yes, with native two-way sync. HubSpot, Salesforce, Pipedrive, and Zapier are also supported, mostly on the Pro tier.
Is Gmelius GDPR compliant?
Yes. Gmelius is built by a Switzerland-based team and aligns with GDPR. They publish a Data Processing Agreement (DPA) and offer EU data residency on higher tiers. Always check their current security and compliance page before signing for sensitive workflows.
Does Gmelius slow down Gmail?
It can with very heavy use, large kanban boards with hundreds of cards or shared inboxes carrying high volume tend to add the most overhead. This is a common trade-off for Chrome extensions that sit on top of Gmail. Most teams don't notice slowdown at typical usage levels.
What happens to my data if I cancel Gmelius?
Your actual emails stay in Gmail; Gmelius doesn't store them. Gmelius-specific data, kanban boards, statuses, shared labels, sequences, and templates, is removed from your account after cancellation. Export anything you want to keep before downgrading or canceling.
