A 15-person team pays between $165 and $975 a month for shared inbox software in 2026, billed annually, depending on the tool and plan. The headline per-user price is only half the story: entry plans often cap the number of seats, AI features can cost extra, and tools that move your team out of Outlook come with migration and retraining time that never shows up on a pricing page.
All prices below come from each vendor's pricing page in November 2026, billed annually unless noted. Prices change often, so check before you buy.
Monthly cost for a 15-person team
| Tool | Entry plan for 15 users | Per user | 15 users per month | Mid-tier plan for 15 users |
|---|---|---|---|---|
| Emailgistics | Starter | $11 | $165 | Professional: $390 |
| Missive | Productive (Starter stops at 5 users) | $24 | $360 | Business: $540 |
| Hiver | Growth | $25 | $375 | Pro: $825 |
| Help Scout | Standard (listed price) | $25 | $375 | Plus: $675 |

Help Scout's pricing page shows one price per plan with a monthly and annual toggle, so its listed prices may change with the billing period you choose.
Seat caps change the math
The cheapest plan on a pricing page isn't always available to your team. Front's $25 Starter plan is limited to 10 seats, so a 15-person team starts at $65 per seat on Professional. Missive's $14 Starter plan is limited to 5 users, so the same team starts at $24 on Productive. Always price the plan your team size actually qualifies for.
What costs extra
- AI. Front's AI Copilot is a $20 per seat add-on on Starter and Professional, which would add $300 a month for 15 people. Emailgistics includes AI message summaries and suggested replies on Professional and Enterprise.
- SLAs and reporting. Some tools reserve SLA rules and detailed reporting for mid-tier plans, so compare the plan that has the features you need, not the entry plan.
- Onboarding. Some vendors charge for implementation or success services. Emailgistics onboarding is free.
The costs that aren't on the pricing page
Tools that replace Outlook carry costs beyond the subscription:
- Migration. Connecting mailboxes, rebuilding folders as labels or tags, and moving workflows into a new app.
- Retraining. Every agent learns a new interface, and productivity dips while they do.
- Two systems. IT manages another app, another set of permissions and another place where email lives.
An Outlook-native tool avoids these because the team keeps working in the same shared mailboxes in Outlook. Read more about the hidden cost of unmanaged shared mailboxes.
Price is only worth it if the tool fits
The right comparison is cost against what the team gets back. On the Professional plan, a 10-person team pays $3,120 a year for Emailgistics, and saving just 20 minutes per person per day pays that back in about six weeks.
