Gmelius vs Mixmax 2026: Shared Inbox vs Sales Engagement

Gmelius starts at $19 a seat and turns Gmail into a shared inbox. Mixmax starts at $29 a seat and turns Gmail into a sales engagement platform. They get lumped together because both live inside Gmail, but they solve different problems: one is built for support and ops teams sharing inboxes, the other for reps running outbound sequences.

How do Gmelius and Mixmax compare on pricing and features in 2026?

Gmelius is a Gmail-native shared inbox for support and ops teams, but it has no sales sequencing or dialer built in. Mixmax is a Gmail-native sales engagement platform, but it has no shared-inbox assignment workflow for a support@ alias. The strongest fit depends on which problem you're solving: Gmelius for collaborative inboxes, Mixmax for outbound sequences, and both if support and sales run out of the same Google Workspace.

Is Gmelius or Mixmax better for a Gmail-only support team?

If support@ or sales@ volume is the problem, not prospecting, Gmelius wins outright. It was built for shared inboxes, internal notes, auto-assignment, and SLA tracking without leaving Gmail.

Front and Missive solve a similar problem, but both pull your team into a separate app. Gmelius doesn't. Every conversation, label, and internal note stays inside the Gmail interface your team already keeps open all day, per Gmelius's product pages. Fewer app-switches means fewer missed replies. The Growth plan at $25/user/month annual, per Gmelius's pricing page, is the real starting point for a team, not Meli. Meli caps out at 5 users and skips automation rules and API access entirely.

Which tool actually drives more sales pipeline: Gmelius or Mixmax?

Mixmax, and it isn't close. Gmelius has no sequence builder, no dialer, and no multi-channel outreach. If reps are prospecting cold, Mixmax's Engagement Copilot at $49/user/month annual is the one of the two actually built for that job.

Mixmax competes with Outreach and Salesloft on paper, but at $49-89 a seat it undercuts both by a wide margin for teams under 50 reps. The catch: Mixmax Suite at $89/user annual bundles Meeting Copilot and Inbox Copilot whether a rep needs them or not, per Mixmax's pricing page. A pure SDR team chasing volume doesn't need meeting-notes AI. Buy Engagement Copilot alone and skip the bundle unless the team genuinely runs meetings through it too.

What do Gmelius and Mixmax cost at 10 seats in 2026?

Ten seats on Gmelius Growth runs $250/month annual, or $3,000/year. Ten seats on Mixmax Engagement Copilot runs $490/month annual, or $5,880/year. A 10-person team covering both support and outbound ends up paying roughly $740/month, about $8,880/year, for two separate Gmail-native tools instead of one bundled suite.

That's still cheaper than a single Outreach or ZoomInfo seat at most agencies, but it isn't free. If outbound is failing on deliverability or list quality, not tooling, spending $5,880/year on Mixmax before fixing infrastructure is the wrong first move. A sequencer sends whatever you load into it. It doesn't fix a burned domain or a stale list.

Modern Inbound doesn't sell shared inbox software or sequence tools. It manages the deliverability, data sourcing, and copy layer that decides whether the emails a tool like Mixmax sends actually land. Teams that already own the stack and need the execution layer running underneath it, that's what the setup engagement covers.

Gmelius vs Mixmax FAQ

Is Gmelius free?

No. Gmelius dropped its free tier. The cheapest plan is Meli at $19/user/month billed annually, capped at 5 users and 5,000 conversations/month, per Gmelius's pricing page. New signups get a 7-day trial of the Growth plan instead of a permanent free tier.

Does Mixmax have a free plan?

Yes. Mixmax Free covers 20 tracked emails and 50 sequence contacts per month with basic meeting scheduling, per Mixmax's pricing page. It's enough to test the product, not to run outbound at any real volume.

Can Gmelius and Mixmax replace each other?

Not really. Gmelius has no sequence builder or dialer, and Mixmax has no shared-inbox assignment workflow for a group alias like support@. Teams running both support and outbound out of Gmail usually license both instead of picking one.

Which is cheaper for a 20-person team?

Gmelius. The Growth plan at $25/user/month annual runs $500/month for 20 seats. Mixmax's Engagement Copilot at $49/user runs $980/month for the same headcount, nearly double, because Mixmax prices for sales output, not inbox management.
