Zendesk vs. Outlook vs. Helply: Which Should Run Your B2B Support?

Key takeaways

• An Outlook shared mailbox works under about 50 tickets a month, then breaks: no assignment, no reporting, no collision detection, and a 50 GB storage ceiling.
• Zendesk fixes the structure but bills per agent. Public tiers run from $55 to $115 per agent per month, Suite Enterprise is custom-priced, and the Copilot AI add-on adds another $50 per agent.
• Helply keeps the helpdesk free forever with unlimited seats and charges only for AI outcomes, starting at $0.25 a draft and $0.50 a resolution.
• For B2B teams, support is account health: Helply loads CRM, Stripe, and Gong context by default and routes churn and upsell signals to the right person.
• Pick Outlook for tiny volume, Zendesk for a mature seat-priced suite, and Helply if you want support to pay for itself.

An Outlook shared mailbox is where you start, not a help desk. It is fine at low volume and costs nothing extra inside Microsoft 365, but it has no ticketing, routing, reporting, or AI.

Zendesk solves the structure problem. It adds tickets, SLAs, macros, reporting, and multi-channel support. The catch is the model: you pay per agent, every month, and the bill grows as you hire.

Helply is a B2B support platform, not a helpdesk in the old sense. The full helpdesk is free forever with unlimited seats, and you pay only when its AI produces a result, such as a draft, a resolution, or a churn signal. For a B2B software team, that model usually wins on both cost and outcomes.

One note on that table: Outlook is the only column that looks free, but free here means no support layer at all, not zero cost to the business.

Why B2B Teams Start in an Outlook Shared Mailbox

Starting in Outlook is a reasonable decision. Your IT team already runs Microsoft 365, so a shared mailbox costs nothing extra and takes minutes to set up. Everyone knows the interface, and at five or ten emails a day it genuinely works.

The problem is not that teams chose wrong. It is that a shared inbox was never built for support, and the cracks only show once volume and headcount climb. That is the next section.

Where the Outlook Shared Mailbox Breaks

As ticket volume grows, an Outlook shared mailbox starts to leak. The failures are predictable, and most teams hit them in the same order.

• No accountability. Everyone sees every message, so nothing is truly owned. Emails slip through the cracks and customers wait.
• No collision detection. Two agents open the same email and both reply. The customer gets duplicate or contradictory answers.
• No support metrics. You cannot measure first response time, resolution time, CSAT, or backlog. Microsoft’s shared-mailbox documentation focuses on access, licensing, and storage limits, not on support metrics.
• No automation or SLAs. There is no routing, no triage, no saved replies, and no way to enforce a response deadline.
• A storage ceiling. A shared mailbox holds 50 GB without a license, and 100 GB with an Exchange Online Plan 2 license, per Microsoft’s Exchange Online limits. Attachment-heavy support fills that fast.

If three or more of those sound like your week, you have outgrown the shared mailbox. The next question is what to replace it with.

Can You Use Outlook as a Help Desk?

Technically yes, but only at very low volume. An Outlook shared mailbox can collect and answer customer email, yet it has no ticketing, assignment, reporting, or AI.

Once you pass roughly 50 tickets a month or add a third teammate, the gaps create more work than they save, and most teams move to a purpose-built platform.

The Usual Fix, and Its Catch: Zendesk

Zendesk is the name most teams reach for, and it does close the gaps. You get a real ticket queue, assignment and SLAs, macros, reporting, a knowledge base, and a Copilot AI assistant.

For teams over 50 agents, its infrastructure is well proven.

The catch is the pricing model. Zendesk charges per agent, so the bill climbs every time you hire. Here is the current Zendesk pricing, billed annually:

Run the math for a 12-agent team. Suite Professional at $115 plus the $50 Copilot add-on works out to about $1,980 a month on those seats alone.

Zendesk also sells a bundled Suite + Copilot Professional rate of $155 per agent, which lands closer to $1,860 a month. Either way, the bill grows every time you hire. There is a second cost too.

Agents leave the Outlook they know for a new interface, which means training time and slower adoption. AI is real on Zendesk, but it sits as a separate line item, not the core of the product.

The Third Option: Outcome Pricing With Helply

Helply takes a different shape. The helpdesk is free forever, with unlimited seats and every channel included. You pay only when the AI delivers a specific outcome. If the AI does nothing, you pay nothing.

That matters for B2B because support here is not high-volume deflection. It is lower volume, higher stakes, and tied to known accounts.

Every ticket is a read on the health of a customer. Helply is built around that idea, with account context loaded from the first word of a ticket.

How Helply charges

What you actually get

• An AI assistant that supercharges agents. It drafts every reply with sources and full account context, so a human stays in the loop and moves faster. This is the most-used capability for B2B teams. See how AI drafts every reply works.
• Autonomous resolution when it is safe. High-confidence tickets are resolved automatically across any channel, while everything else goes to a person with a drafted reply ready.
• Revenue signals routed to the right team. Every ticket is scanned for churn risk, upsell intent, and competitor mentions, then sent to the CSM, AE, or Product owner.
• Deep channels and account context. Slack Connect, Microsoft Teams, Discord, email, in-app chat, SMS, and WhatsApp all feed the same context layer, with CRM, Stripe, and Gong data attached. This is the foundation of support as a revenue engine.

Helply is built for B2B software companies in the $1M to $50M ARR range. It is not for B2C, ecommerce, agencies, or marketplaces. Naming that boundary is the point. Focus is what makes the AI accurate on technical, account-based tickets.

What Is the Best Way to Run Support for a B2B SAAS Team?

It depends on volume and on how you want to pay. If you handle a handful of emails a week, stay in Outlook. If you want a mature, seat-priced suite and can absorb a bill that grows with headcount, Zendesk fits.

Helply is the strongest match for a growing B2B software company. You want the full support layer for free, AI you only pay for on results, and support that surfaces revenue rather than just closing tickets. The model treats support as account health instead of cost.

When to Choose Which

• Outlook. Stay in Outlook only if you handle under about 50 tickets a month, have one or two people, and need no reporting.
• Zendesk. Choose Zendesk if you want a mature seat-priced suite and your budget can scale predictably with every new hire.
• Helply. Choose Helply if you are a $1M to $50M ARR B2B software team that wants a free helpdesk, AI paid only on results, and churn and upsell signals tied to known accounts.

How to Move off a Shared Mailbox

Switching is lower risk than most teams expect. A clean migration follows five steps.

• 1. Connect your channels first, starting with email and the chat or Slack channels your customers already use.
• 2. Train the AI on your past tickets, knowledge base, and help docs, which is the richest source you have.
• 3. Connect your context layer, such as your CRM and Stripe, so account data rides along with every ticket.
• 4. Turn on outcomes, beginning with drafts so a human reviews everything before resolutions go live.
• 5. Go live and watch the first signals appear. The migration playbook walks through each step.

The Bottom Line

Outlook is the start line, not the destination. Zendesk fixes the structure but charges for every seat, so the cost grows as your team does.

Helply gives you the full support layer free and charges only when AI produces a result, while turning each ticket into a signal about the account behind it.

For a B2B software team that wants support to stop being a cost center, the choice is clear. Helply is free to start, and you pay for outcomes, not seats.
