Shared inbox software pricing usually comes down to one number: what you pay per person, per month. In 2026 most paid tools land somewhere between $10 and $30 per person for an entry plan, and the price climbs fast once you want rules, reports or a second channel. Here's how the bills are built, what to expect at three team sizes, and how to spot the charges that don't show up on the pricing page.
How shared inbox software pricing works
A shared inbox lets a team read and answer one email address together. Nobody replies twice, and everyone can see who owns what. Simple idea. The pricing is where it gets messy.
Vendors tend to pick one of four ways to charge:
- Per seat: you pay for each teammate who logs in. This is the most common model.
- Per contact: the price follows how many customers you talk to, not how many people answer.
- Per ticket or conversation: a monthly allowance, with extra fees past it.
- Per resolution: a fee each time the bot closes a question. We break that one down in our post on per resolution pricing.
Per seat is easy to plan around. The other three move with your volume, which makes next month's bill a guess. Our guide to help desk pricing models walks through the trade-offs in more detail.
What you'll pay by team size
Let's use a per-seat tool at $19 per person a month, which sits near the middle of what 2026 pricing roundups report for entry plans. Prices change often, so treat this as an example and check each vendor's site.
- Two people: $38 a month.
- Five people: $95 a month.
- Ten people: $190 a month.
Looks fine. Then the extras arrive. Many vendors put rules, automation, reports and extra channels on higher tiers, so the plan you really need can cost two or three times the headline price. A few also set a minimum seat count or bill monthly at a higher rate than annual.
The same five-person team on SupportifyGPT pays $39 a month on Growth, which covers up to 3 seats, or $79 a month on Enterprise, which covers up to 10. Every feature is on every plan. The tiers only differ by how many seats you get. That's flat pricing, so you always know the bill before the month starts.
Free options and where they stop
If you already pay for Google Workspace or Microsoft 365, you have a free way to share a mailbox. Google calls it a collaborative inbox. Microsoft calls it a shared mailbox.
These work for a small team that only needs to see the same emails. They get thin quickly. You usually can't see who's handling a message, set response-time targets, add a live chat widget or build a help center. Once you're copying and pasting between tabs, you've outgrown a free inbox. Our post on free help desk software covers what the free tiers really include.
The costs that hide behind the price
The monthly price is only the start. Before you commit, ask about these:
- Is the price shown for annual billing, and what does it cost month to month?
- Which features sit on higher plans, such as rules, reports or integrations?
- Is there a minimum number of seats?
- Are there setup or onboarding fees?
- Does the support bot cost extra, and how is it metered?
Our hidden costs of help desk software post goes deeper on each one. And if you're weighing specific tools side by side, the comparison pages show the honest numbers with the date we checked them.
How to choose without overpaying
Start by counting the people who'll actually answer customers. Owners often count themselves, a part-time helper and a bookkeeper who'll check in twice a month. Only the first two need a seat on most plans.
Next, list the features you'd miss on day one. For most small teams that's a shared inbox, ticket assignment, a few saved replies and a way to see response times. Then price that list on two or three tools, with the extras added in, and compare the totals instead of the headlines.
Last, run a trial with real email. The best test is a normal Tuesday. If your team answers faster and nothing slips through, you've found a fit. You can start a 14-day free trial of SupportifyGPT and see all of the features on any plan. Or look at the pricing page first and do the math yourself.
One more thing worth knowing: on SupportifyGPT the support bot writes answers from the articles you wrote, and says so when it doesn't know. It's included on every plan with no per-answer fee, so a busy month never turns into a surprise bill.
