Gmelius vs Streak: Shared Inbox or CRM? Here's the Real Difference
Most comparison articles treat these two like interchangeable Gmail add-ons. They're not. The Gmelius vs Streak decision comes down to one question: do you need a shared inbox for your team, or a CRM for your pipeline? Both live inside Gmail, both have loyal users, and both will frustrate you if you pick the wrong one.
30-Second Verdict
Pick Gmelius if your team manages shared inboxes (support@, sales@, finance@) and needs collaboration features like assignment, notes, and automation rules. It holds a 4.4/5 on G2 from 776 reviews.
Pick Streak if you're a solo rep or small sales team tracking deals in a visual pipeline without leaving Gmail. It edges ahead with a 4.5/5 on G2 from 260 reviews.
Skip both if your real bottleneck is bad contact data, not inbox management. No inbox tool fixes a list that bounces 20% - start with data enrichment and verification.
What Each Tool Actually Does
Gmelius solves the "who's handling this email?" problem. Your support team is forwarding emails back and forth, customers get duplicate replies, nobody knows what's assigned to whom. Gmelius turns Gmail into a shared workspace with shared inboxes, Kanban boards, collaborative notes, and Sequences for multi-stage campaigns. Its built-in AI assistant, Meli, helps draft replies, organize email, and route conversations.
Streak solves a completely different headache. You're juggling 40 deals across sticky notes, spreadsheets, and your memory. Streak embeds a full CRM pipeline directly into Gmail - visual deal stages, mail merge with automatic follow-ups, Magic Columns that auto-track engagement, and task reminders synced to Google Calendar. We've tested it extensively, and it genuinely feels like a CRM that never asks you to open another tab.

| CRM pipelines | ❌ | ✅ Core feature | Streak |
| Email tracking | ✅ | ✅ Free-forever email tools | Streak (free tools) |

Here's the thing: Streak is the better product for one person. Gmelius is the better product for any team. If you're a two-person startup unsure which you need, start with Streak - you'll outgrow it before the collaboration pain hits, and the free tools buy you time.
If you're building outbound alongside this, pair your Gmail workflow with sales prospecting techniques and a clean list.
Neither Streak nor Gmelius can fix bad contact data. Before you pick a Gmail tool, make sure your list is worth managing. Prospeo verifies emails at 98% accuracy on a 7-day refresh cycle - so your pipeline stays clean whether you route it through a shared inbox or a CRM.

Pricing Breakdown
Both tools gate features aggressively. The limits aren't always obvious upfront.
Gmelius Pricing
From their pricing page:
| Plan | Annual | Monthly | Conversations/mo | Rule executions/mo |
|---|---|---|---|---|
| Meli | $19/user/mo | $24/user/mo | 5,000 | - |
| Growth | $25/user/mo | $30/user/mo | 10,000 | 10,000 |
| Pro | $40/user/mo | $45/user/mo | 100,000 | 100,000 |
| Enterprise | Custom | $45/seat/mo | Unlimited | Unlimited |
Watch the fine print: Gmelius caps you at 5,000 conversations/month on their cheapest plan, and that wall comes fast for active teams. All team members must be on the same plan - no mixing tiers. The 7-day Growth trial doesn't require a credit card.
Streak Pricing
From their pricing page:
| Plan | Annual | Monthly | AI credits/mo | Mail merge |
|---|---|---|---|---|
| Free tools | $0 | $0 | 0 | 50/day |
| Pro | $49/user/mo | $59/user/mo | 10 | 1,500/day |
| Pro+ | $69/user/mo | $89/user/mo | 50 | 1,500/day |
| Enterprise | $129/user/mo | $159/user/mo | 500 | 1,500/day |
Streak's free email tools - tracking, snippets, 50/day mail merge - are genuinely free forever. That's a real differentiator for solo reps doing light outreach, especially if you follow a repeatable sales follow-up system.
What Users Actually Say
We've seen teams outgrow Streak's collaboration limits faster than expected, and the reviews confirm it. Reps love the tight Gmail integration and ease of use, but Gmail lag is the recurring complaint. One G2 reviewer wrote they "actually disabled it" when Streak slowed their inbox to a crawl. Reporting is basic, and collaboration breaks down past 10-15 users.
Gmelius earns praise for automation and team workflows. Teams running shared inboxes find it genuinely useful. The weak spot is mobile - the app shows up in nearly every critical review - and surprise usage caps frustrate growing teams who didn't read the fine print.
On TrustRadius, overall scores are close (Gmelius 8.0/10, Streak 8.3/10), but Gmelius pulls ahead on Likelihood to Recommend: 9.8 vs Streak's 7.0. Sample sizes are small, but the gap suggests Gmelius users stick around longer.
Who Should Pick Which
Pick Gmelius if you manage shared inboxes, need Kanban boards for email workflows, and your team is 5-50 people. It's the collaboration play. If you're evaluating broader options, compare against other contact management software too.
Pick Streak if you're a solo rep or small team under 15, need visual deal pipelines, and want free email tracking. It's the individual productivity play - and a good example if you're learning examples of a CRM.
Pick neither if you need strong reporting or mobile-first workflows. At that point, you're usually better off with a dedicated shared inbox platform like Front or Hiver, or a dedicated CRM like Pipedrive or Copper - both common top alternatives on G2.
The Piece Both Tools Ignore
Let's be honest about something: choosing between Gmelius and Streak only matters once you have the right people to email. Streak's pipeline is useless if half your emails bounce. Gmelius's shared inbox doesn't help if the leads coming in are junk.
That's where your data layer matters. Prospeo, for example, delivers 98% email accuracy on a 7-day refresh cycle, with a free tier of 75 emails/month - so you can validate your contact list before it ever hits your inbox tool. Find the right contacts first, then manage them in whichever Gmail tool fits your workflow. If bounces are a recurring issue, fix your email bounce rate and follow a proper email deliverability checklist.
Streak's mail merge tops out at 1,500/day. Gmelius caps you at 5,000 conversations/month. Both limits hurt more when 20% of your sends bounce. Prospeo's 98% email accuracy at ~$0.01/email means every send counts - no wasted credits, no domain damage.
Fix the data layer before you optimize the inbox layer.
