Gmelius vs Streak: Which Gmail Tool Is Better in 2026?
Both Gmelius and Streak live inside Gmail and add team workflow features on top. They overlap on kanban boards and team collaboration, but their core focus is different. Gmelius is a collaboration suite (shared inboxes + sequences + automation). Streak is a Gmail CRM (visual pipelines for deals, hiring, projects).
Pick Gmelius if shared Gmail inboxes are central to your work, with sequences and automation as bonus features (from ~$15/user/mo). Pick Streak if you primarily need a CRM-style pipeline inside Gmail with a usable free plan (from $15/user/mo, free tier available).

What is Streak?
Streak is a Chrome extension that adds a CRM layer directly into Gmail. It pioneered "boxes" and "pipelines" that let you organize Gmail threads into kanban-style workflows for sales deals, hiring, fundraising, or any process tied to email conversations.
Key strengths:
- Visual pipelines (boxes + stages) for tracking deals and projects, the cleanest in the category
- Generous free plan (basic pipelines, ~50 mail merges/day, email tracking)
- Thread sharing across teams without forwarding
- Simple to adopt for teams already living in Gmail
- Used heavily for non-sales workflows (hiring, fundraising, project intake)
Key weaknesses:
- No automated sequences, only one-shot mail merges
- No shared inboxes the way Gmelius / Hiver / Front do them
- Gmail can slow noticeably on large pipelines
- Per-user pricing scales fast for larger teams
- Gmail-only, no Outlook

Your team needs multi-step outreach sequences that stop when a prospect replies. Which tool handles this natively?
Right! Gmelius Growth offers multi-step sequences with auto-stop on reply. Streak only does one-shot mail merges; no automated follow-up sequences. For sequences, Gmelius (or Mixmax) is the fit.
Streak's mail merge sends a one-time batch but doesn't automate follow-ups. Gmelius Growth has true sequences. For more advanced sequences, Mixmax is even stronger.
Who should choose Gmelius?
- Support, ops, or customer success teams with shared support@ / sales@ inboxes
- Small teams wanting shared inboxes plus sequences in one tool
- Teams that already use Slack or Trello (deep two-way sync)
- Anyone running email-driven workflows (intake, hiring, ticket triage)
- Privacy-focused EU teams that prefer a Swiss vendor
Who should choose Streak?
- Solopreneurs and small teams that need a lightweight CRM inside Gmail
- Non-sales use cases: hiring pipelines, fundraising, project tracking
- Teams that want clean visual pipelines with custom fields and formulas
- Anyone wanting a usable free CRM plan (Streak's is the best in the category)
- Teams that don't need automated sequences and can live with mail merges
A 6-person support team uses a shared support@ Gmail inbox and wants assignment, statuses, internal notes, and SLA reporting. Which fits better?
Right! Gmelius's shared Gmail inbox with assignment, statuses, and SLA reporting is built specifically for this use case. Streak's thread sharing is for collaborating on individual conversations, not running a team mailbox.
Streak's thread sharing isn't a true shared inbox. Gmelius (or Hiver) is the right fit for a team mailbox with assignment and SLA tracking.
Can you use both Gmelius and Streak?
Technically yes, but they overlap heavily on kanban boards and team collaboration. Most teams pick one. If you really need Streak's CRM-grade pipelines AND Gmelius's shared inboxes, expect to pay roughly $30-40/user/month combined, and you'll have two extensions fighting for Gmail's UI.
A more common setup: Streak alone for CRM (pipelines + free tier), or Gmelius alone for shared inboxes (with kanban as a bonus). Pick the tool whose core feature is your core need.
The case for neither: focused alternatives
Both tools are jack-of-all-trades. Focused tools usually do their one job better:
| If you need... | Better choice | Why |
|---|---|---|
| A real CRM | HubSpot Free CRM | Free tier, custom objects, automations, reporting |
| A pure shared inbox | Hiver or Front | Built specifically for this; cleaner setup |
| Sales sequences | Mixmax | Branching sequences + the best inline scheduler |
| Cold email at volume | Instantly | Inbox rotation; flat $30/mo |
| Outreach in Outlook + Gmail | Yesware | The only top-tier cross-client option |
A simpler alternative: MentionAgent
Gmelius and Streak both require you to build and manage outreach yourself. You source leads, write emails, manage pipelines, and configure rules. If your goal is specifically link building or blog outreach, MentionAgent takes the opposite approach.
MentionAgent finds relevant blogs in your niche, looks up contacts, writes personalized pitches, and handles follow-ups. You just approve the emails before they send. No pipelines to build, no shared inboxes to set up, no per-user fees.
- Price: $99/mo flat, same for a team of 1 or 10
- Setup: Minutes, not hours
- Your job: Approve emails. That's it.
A 10-person team on Streak Pro ($49/user/mo) pays how much per year vs. a flat-rate tool at $99/mo?
Right! 10 users * $49 * 12 = $5,880/year. A flat $99/mo tool is $1,188/year. For larger teams, per-user pricing on Streak (and Gmelius) gets expensive fast.
10 users * $49/mo * 12 months = $5,880/year for Streak Pro. A flat-rate tool at $99/mo costs $1,188/year. Per-user scales linearly; flat doesn't.
No pipelines. No shared inboxes. Just placements.
MentionAgent finds relevant blogs, looks up contacts, writes personalized pitches, and follows up. Flat $99/mo for your whole team. No Gmail extensions required.

Frequently asked questions
Is Gmelius or Streak better?
Gmelius for shared inboxes plus sequences and automation. Streak for a Gmail CRM with cleaner visual pipelines and a usable free plan. They share kanban-style boards but have different core focus.
Which is cheaper, Gmelius or Streak?
Both start at ~$15/user/mo. Streak's free plan is dramatically more usable. For sequences, Gmelius Growth (~$24/user/mo) is cheaper than Streak Pro ($49) needed for shared pipelines.
Can I use Gmelius and Streak together?
Technically yes, but heavy overlap on kanban + collaboration. Most teams pick one. If both, expect ~$30-40/user/mo combined and two Gmail extensions competing for UI space.
What's a better alternative to both?
For a real CRM, HubSpot Free CRM. For shared inboxes, Hiver or Front. For sales sequences, Mixmax. For automated link building outreach, MentionAgent ($99/mo flat).
Does Gmelius or Streak work with Outlook?
Neither. Both are Gmail / Google Workspace only. Outlook users should look at Yesware for the closest cross-client equivalent.
Does Streak have shared inboxes like Gmelius?
Not in the same way. Streak supports thread sharing across teams without forwarding, but it's not a shared inbox with assignment, statuses, and SLA tracking. Streak is built around pipelines, not team mailboxes.
Which has a better mobile app, Gmelius or Streak?
Both have iOS and Android apps. Streak's mobile app is more mature and widely used for working pipelines on the go. Gmelius's app focuses on reading shared inboxes and replying inside sequences. Heavy board or campaign editing happens on desktop in both.
Can I migrate data between Streak and Gmelius?
Partially. Contacts, deals, and template content can be exported as CSV from either tool and re-imported. Pipelines, kanban boards, and automation rules don't import directly; you'll need to recreate them. Your Gmail emails stay in Gmail and aren't moved.
Which is better for hiring or recruiting pipelines?
Streak. Recruiters commonly use Streak's pipelines for candidate tracking because of the visual stages, custom fields, and Gmail-native thread linking. Gmelius can do this with kanban boards, but Streak's data structure (custom columns, formulas) is closer to a real ATS.
