A client sends a correction to hello@agency.com while the account manager is out. One teammate starts a reply; another has already prepared a new email with the revised quote. Both need a second pair of eyes before anything leaves the inbox.

For a three-person Gmail team, Gmelius vs Hiver is a purchasing decision about who owns a reply, how a new draft gets reviewed, and how many seats must be paid for. Both add teamwork to Gmail. The practical differences appear when a three-person team pays for seats, shares a draft that is not a reply, or needs to tell a support queue from an ordinary client relationship.

Quick answer: Gmelius Growth is the more economical three-person Gmail shared inbox on published seat pricing. Hiver in Gmail is worth examining when support-style ticketing and a documented new-email shared-draft workflow matter more. Neither product should be assumed to enforce managerial sign-off simply because it has shared drafts or collision alerts.

Gmelius vs Hiver for three Gmail users: the short answer

Decision point	Gmelius	Hiver in Gmail
First paid plan with shared inboxes	Growth, $25/user/month billed annually	Growth, $25/user/month billed annually
Three-person annual bill	$900 for three Growth seats	$1,500 at the published five-seat step
Shared inbox allowance on that plan	Unlimited shared inboxes and labels	Two shared inboxes
Co-writing a reply	Shared drafts for shared conversations	Shared drafts in existing conversations
Starting a new shared draft	Help article describes a Google Docs route rather than direct new-thread sharing	Help article documents a new shared email from scratch
Best reason to shortlist	Gmail labels, shared workspaces, automation	Ticketing, service queue ownership, support reporting

The useful comparison is not a feature tally: it is the price and handoff for this specific team. Start with the email you actually need to send, then price the plan that supports it. See the Gmelius pricing page and Hiver in Gmail pricing page for current terms.

The three-person bill is not $75 versus $75

The headline annual price is $25 per user per month for both products’ relevant Growth tiers. That makes a three-person team look like a $75/month purchase on either side. The billing rules change the calculation.

Gmelius defines a user as a Google or Google Workspace email account on the subscription and lists Growth at $25 per user per month when billed annually. It also says everyone on the team must use the same plan. Its cheaper $19 Meli tier is a personal AI assistant plan; the feature table does not include shared inboxes there. For shared client mail, start the estimate at Growth, not Meli.

On its current pricing page, Hiver says plans start with two seats, increase from two to five, then grow in steps of five. Under that published rule, three active people require the five-seat step. That is an important difference for a small agency that cannot make use of the two extra seats.

People who need access	Gmelius Growth, annual commitment	Hiver Growth, annual commitment
2	$600/year (2 seats)	$600/year (2 seats)
3	$900/year (3 seats)	$1,500/year (5-seat step)
5	$1,500/year (5 seats)	$1,500/year (5 seats)

On month-to-month billing, the same three-person illustration becomes $99/month for Gmelius Growth (3 × $33) and $175/month for Hiver Growth (5 × $35).

These are calculations from published list prices and seat rules, not quotes. They exclude taxes, existing Google Workspace licenses, discounts, and additional services. Confirm the five-seat rule in Hiver’s checkout or with sales before committing, since packaging can change.

At five users, the entry-plan price difference disappears. The next question is how many inboxes the team needs: Gmelius lists unlimited shared inboxes on Growth, while Hiver lists two on Growth and five on Pro. That limit matters if hello@, billing@, and support@ need distinct ownership and reports.

A reply draft and a new quote are different jobs

Imagine two pieces of work on the same Tuesday. First, a client replies to a project thread asking for a deadline change. Second, the team wants to send a fresh quotation to a prospect who has never emailed the shared address. Both messages need internal review.

Both vendors document shared drafts for ongoing conversations. Gmelius’s shared-draft help article explains how teammates share and edit a reply inside a shared conversation. Its currently available instructions also state that sharing a draft directly from a new email thread is not supported in that workflow and point to a Google Docs approach. Because the article refers to an older change, verify this specific limitation during a current trial rather than treating it as a permanent product rule.

Hiver’s shared-drafts guide documents both routes: share a draft in an existing conversation, or compose a new email from scratch and invite teammates to work on it. It also tells users to check the sending address before anyone clicks Send. That matters when the client should see hello@agency.com, not an individual employee’s address.

This becomes visible in a real client handoff. An agency may send more new proposals, renewals, and status reports than replies to incoming tickets. If a new-message draft must move between writer, reviewer, and sender without copying text to another app, test that exact path first.

A shared draft is still not a guaranteed approval lock. Write down who can edit, who may send, and what counts as approval. Our shared-inbox duplicate-reply workflow separates visibility, ownership, and permission to send because those are different controls.

One Gmail surface, two operating models

Gmelius is designed around shared Gmail conversations, labels, assignment, and rules. Its Growth plan includes shared inboxes and labels, shared drafts, collision detection, automatic assignment, templates, and analytics. The pricing table also sets limits: up to 10,000 email conversations and 10,000 rule executions per month on Growth. Gmelius defines a conversation as a Gmail thread entering a Gmelius workspace, so ask how that count behaves if the same client thread appears in several shared workspaces. The public pricing table does not give an overage price or explain what happens at the cap; ask the vendor before relying on a high-volume workflow.

Hiver in Gmail emphasizes a ticketing-style support queue. Growth includes shared inboxes, assignments, rule-based automation, and pre-built analytics, with two inboxes, ten automations per inbox, and up to ten users according to the published feature table. Pro adds features such as service-level targets, customer-satisfaction surveys, and more advanced reporting. Hiver also offers a separate product, Hiver Omni, for teams that need a standalone multichannel service platform. Do not mix Omni claims into a comparison of the Gmail extension.

For a small consultancy, the distinction often comes down to the kind of work in the inbox. If the team shares account relationships and project threads, shared labels and flexible routing may be the center of the workflow. If it runs a customer-support queue where requests must be assigned, tracked, and measured, the ticketing model deserves a closer look.

A shared inbox still needs a person responsible for the next reply. Both document collision warnings that alert people to overlapping activity; a warning is not proof that a second sender cannot act. Gmelius describes alerts when another teammate is viewing or replying, while Hiver describes a banner when someone else begins drafting. Use a real two-person test rather than assuming either tool is a hard send lock.

AI is part of the plan, not the buying criterion

Gmelius now markets AI assistants alongside Gmail collaboration. Hiver’s Growth tier lists AI Agents and AI Copilot as part of its offering. Their marketing labels are not a reliable basis for declaring one model more accurate or safer, and there is no independently measured output quality in this article.

For client-facing email, keep AI-generated replies in draft status until a human checks dates, amounts, commitments, and confidential information. Ask each vendor what usage limits apply to your chosen AI features, what customer data the feature reads, and whether an administrator can restrict automated sending. A cheap seat does not help if the workflow sends an unapproved promise.

If your main need is only email summarization or rewriting, compare the incremental value against Gemini already inside Gmail. The paid shared inbox earns its keep through ownership, handoffs, and shared history, not another rewrite button.

Run one awkward afternoon through both trials

Do not import a year of client email to discover that the first important handoff is awkward. Use a small test mailbox and three teammates, with no sensitive real-client data. Both vendors advertise seven-day trials. Gmelius says its trial starts on Growth; Hiver says its trial opens Elite features. Test the paid Growth tier separately rather than assuming every trial feature survives checkout. Record the plan you are actually evaluating.

1. New inbound request: send a message to hello@, assign one owner, add a private note, and hand it to a second person.
2. Shared reply: draft a response, request edits, then check who can change or send it.
3. Brand-new outbound email: create a fresh quotation, share the draft for review, and inspect the From address on the final message.
4. Collision test: have two teammates open and begin replying to the same conversation. Record what the warning does and does not prevent.
5. Absence and access: remove the original owner from the queue, then check whether the remaining team can find context without accessing unrelated personal email.
6. Paid-tier reality: verify the actual number of seats, inboxes, automation rules, and AI usage limits shown at checkout.

Keep a simple scorecard with four columns: task, expected behavior, observed behavior, and blocker. Ignore the features your team will not touch. What matters is whether a reviewed message reaches the right client once, from the right address.

A third option is to keep a lighter Google Workspace setup until the workload justifies a paid team inbox. If you are comparing broader client-email tools, our Missive vs Hiver guide examines the cost of leaving Gmail versus staying inside it. Our Missive vs Front review goes deeper on shared drafts and client sign-off in standalone email clients.

Which one should a small Gmail team choose?

Shortlist Gmelius Growth if your team has three Gmail users, multiple shared labels or inboxes, and a workflow built around assigning client threads rather than managing a formal support desk. The published three-seat bill is lower, but the direct new-outbound shared-draft path deserves a trial check if your team sends many fresh proposals.

Shortlist Hiver in Gmail Growth if you want support-style conversation ownership, a documented shared-draft path for new emails, and reporting around a small service queue. Be comfortable with the two-inbox limit and confirm the five-seat pricing step for a three-person team. If service-level agreements, customer-satisfaction surveys, or advanced analytics are non-negotiable, price Hiver Pro rather than comparing its Growth price to a higher-tier requirement.

Choose neither yet if the real problem is simply that teammates do not know who is replying. Set one owner, one reviewer, and one final sender in the existing mailbox first. Then decide whether software is needed to make that rule visible and durable.
