Plain vs Outlook

Plain has taken a unique approach to the best help desk space by doing what the name suggests and taking a more "plain" and simple approach to it all.

A single inbox for support teams to prioritize and respond to customers across email, Slack, and other areas. You're not meant to think of Plain as a shared inbox, like many of the other best help desks mentioned.

Plain is focusing heavily on product-teams that can benefit from deeper integrations with tools like Linear, Slack, and Stripe.

• For product-led teams where support and engineering need to stay closely connected
• Deep integrations with Slack, Linear, and Stripe that few help desks offer
• API-first architecture makes it flexible for developer-heavy teams
• Clean, minimal interface centered around a single inbox
• Great Slack workflows (turn messages into tickets and Linear issues)

• Not designed as a traditional shared inbox (contact@, billing@, admin@ workflows)
• Best suited for technical teams, which may limit adoption for non-technical support staff
• Fewer mature help desk features compared to established tools like Help Scout or Zendesk
• Knowledge base and automation capabilities are more limited

The standout features of Plain are actually the deep native integrations. If you're using Stripe for your product, you can easily display all the details of the plan and purchases on the right-hand side.

In-fact, the same is the case with Linear + Slack, you can easily turn a Slack message into a support ticket and spin up a Linear issue from that, pulling in full context to one place:

Plain Integration with Linear

So if you're a team especially that has shared Slack channels with customers/partners, Plain has a pretty impressive integration with Slack that we haven't really seen with any other Help Desk on the market.

If any of the above integrations sound exciting, they great! You're probably in their target customer profile, if not? That makes sense, it's for quite a specific type of product team, one that is likely using Linear and Slack already.

Just to be clear, Plain is not a shared inbox in the general sense, so you're not going to want to send to it "contact@ admin@ billing@", you're going to only want to use it for your support@ channel, for customers who you specifically want to respond to, likely via an SLA.

If you're looking for a more traditional help desk (or shared inbox), you might want to check out Help Scout instead. That said, if the above fits your use-case, then we think plain is a fantastic choice, and super promising in the somewhat stagnant and uninspiring help desk space!

If you're a larger enterprise, you're likely using Outlook instead of Gmail (Google Workspace) to manage your email and calendar for work.

That said, most startups and quickly growing companies use Google Workspace, so if you're looking into Gmail vs Outlook, we believe Gmail is the clear winner here. It just has a more user-friendly experience all-around, and has significantly more integrated tools ( most modern tools integrate with Gmail over Outlook).

If you're "stuck" with Outlook and want to make your email experience 10X better, using Outlook in addition to a platform like Superhuman email is the way to go.

• All-in-one email and calendar solution within Microsoft 365
• Tight integration with other Microsoft tools
• Familiar interface for long-time enterprise users
• Standard choice for companies already committed to Microsoft

• Clunkier user experience compared to modern email clients
• Fewer modern integrations compared to Google Workspace
• Limited “Sign in with Microsoft” support across newer SaaS tools
• Most modern startups and tools prioritize Google compatibility
• Rarely a proactive choice for small business owners

Outlook combines your inbox and calendar into a single interface. Giving you the ability to respond to your emails, check calendar availability, schedule a meeting, and send out invites, without switching tools.

For companies already using Microsoft 365, you know it works and that it’s functional. You also know it lacks that modern feel that places importance on speed and focus.

Outlook connects directly with the rest of the Microsoft ecosystem (Word, Excel, Teams, SharePoint, and OneDrive). And that's great if 365 is what you're committed to, but when you're looking to create a tech stack outside of their system, it suddenly becomes a lot less compelling.

Large enterprises rely on the level of oversight that Microsoft provides. It provides strong security, compliance features, and centralized admin controls, but this is a great example of just because flagship companies are using it doesn't mean it's what's best for you and your team.

If your team is a smaller and fast-moving team, this level of complexity will probably feel like overkill.

Outlook itself is included with Microsoft 365, and pricing varies depending on features and region. Most Microsoft 365 plans start around:

• Business Basic: ~$6/user/month
• Business Standard: ~$12.50/user/month
• Business Premium: ~$22/user/month
