Mail is not sold on its own, and the cheapest plan that includes it is Business at $33 per member per month billed annually, or $40 monthly.**Slashy is a focused AI email product** at $25 per user per month billed annually, or $30 monthly, with a seven-day trial that requires a credit card.**The $8 difference is not the interesting part.** You are choosing between a suite where email is one of four things, and a single product that only does email.**Neither company publishes which email providers it supports** on its homepage or pricing page. Confirm before you buy, especially on Outlook.- Superhuman has scale and compliance behind it. Slashy has focus and a lower entry price.\n\nAnyone comparing these two in 2026 is usually reacting to the same thing: Superhuman got more expensive and more complicated, and a wave of cheaper AI email products arrived while that happened. Slashy is one of the more credible ones.\n\nWe build a competing product, which we will get to at the end. Nothing below depends on that. All prices and features here come from each company’s own pricing pages, checked on 4 August 2026.\n\n## What Superhuman is now\n\nThis is the part most comparisons miss, and it changes the math.\n\nSuperhuman today sells a suite of four products. Mail is the email client people know. Grammarly is the writing assistant. Docs is a collaborative document tool. Go is an agent that works across applications.\n\nThe plan structure follows from that:\n\n| Plan | Price (annual) | Price (monthly) | Includes Mail |\n|---|---|---|---|\n| Free | $0 | $0 | No |\n| Pro | $12 / member | $15 | No |\nBusiness | $33 / member | $40 | Yes |\n| Enterprise | Custom | Custom | Yes |\n\nMail appears only at Business and above. There is no way to buy the inbox by itself, so anyone who wants Superhuman Mail is buying Grammarly, Docs and Go along with it whether they use them or not.\n\nWhether that is good or bad depends entirely on whether you would otherwise pay for a writing assistant and a docs tool. If you would, the bundle is strong value. If you only want a faster inbox, you are paying for three products to get one.\n\n## What Slashy is\n\nSlashy sells one thing: an AI email client. One plan, Professional, at $25 per user per month billed annually or $30 monthly, plus a bespoke Enterprise tier. The trial runs seven days and asks for a credit card up front.\n\nWhat is included, per its own plan details: replies drafted in your voice, inline rewrites, voice drafts, reusable snippets, a personalized memory of your relationships and preferences, plain-language search, thread summaries, meeting preparation, reminders and follow-ups, intelligent labels and archiving, open tracking, calendar management, availability and team scheduling, unlimited connected inboxes, private team comments, and Mac, iPhone and web apps.\n\nTwo things stand out. **Automations** run on triggers rather than only on demand: when email arrives, before a meeting, or on a schedule you set. And **you can reach it from iMessage and Slack**, so the assistant is available in the apps where you are already typing.\n\nEnterprise adds SSO and SCIM, a security review package, guided onboarding, a dedicated account manager and custom data controls.\n\n## Where the two actually differ\n\nFeature lists overlap more than either would admit. Both draft in your voice, both summarize threads, both do calendar and scheduling, both do snippets, both offer plain-language search, both prepare you for meetings, both have an MCP surface, both do team collaboration on threads.\n\nThe real differences are these.\n\n**Scope.** Superhuman is a bundle where email is one component. Slashy is an email product. That is the decision, and everything else follows from it.\n\n**Where the assistant lives.** Slashy’s is reachable from iMessage and Slack. Superhuman’s lives in the Superhuman apps. If you want to fire off a request from your phone’s messaging app rather than opening another client, that is a genuine gap between them.\n\n**CRM.** Superhuman Business reads HubSpot, Salesforce and Pipedrive inside the inbox. That is read-only, but for a sales team it removes a lot of tab-switching. Slashy does not publish an equivalent.\n\n**Compliance.** Superhuman lists SOC 2 Type 2, SAML SSO, SCIM, audit logs, data loss prevention and BYOK encryption at the higher tiers. Slashy lists SSO, SCIM and a security review package at Enterprise. If you have a security review to pass, Superhuman publishes more detail about what it will survive.\n\n**Scale.** Superhuman claims over 40 million people and 50,000 teams across the suite. Slashy is a newer, smaller company. That cuts both ways: one is a safer institutional bet, the other is more likely to ship something you asked for.\n\n## What neither of them tells you\n\nWe went looking for which email providers each one supports, because for most buyers that is the first question and it decides the purchase.\n\nNeither answers it where you would expect. Slashy’s homepage does not mention Gmail, Google Workspace, Outlook or Microsoft anywhere. Its pricing page has a FAQ entry titled “Which email providers does Slashy work with?” and another asking “Do I need to migrate away from Gmail?”, which implies a Gmail orientation without confirming what else is covered. Superhuman’s plans page does not name providers either.\n\nIf you run on Microsoft 365, ask both vendors directly and get the answer in writing before you pay. It is the single fastest way to waste a trial.\n\n## Which one should you pick\n\n**Choose Superhuman if** you would pay for a writing assistant or a docs tool anyway, you need CRM context inside the inbox, or you have a procurement process that wants SOC 2 Type 2 and BYOK on the page before it will talk to you. At $33 the bundle is doing real work beyond email.\n\n**Choose Slashy if** you want an inbox product and nothing else, you value reaching the assistant from iMessage or Slack, or $25 against $33 matters at your headcount. You are buying focus, and focus is worth something.\n\n**Choose neither if** your problem is not email. Both of these make one inbox faster. If the work arriving at your team is spread across Slack, Teams, Google Chat and WhatsApp as well as email, a faster email client leaves most of it untouched.\n\n## Where we fit\n\nWe build [this+that](/), so treat this as disclosure rather than analysis.\n\nWe are not trying to be a better email client than either of these. We work across email and chat together, turn what arrives into tracked tasks with owners, run workflows on those messages, and keep a shared brain of what the team knows so the AI is answering from your business rather than guessing. It is free during the open beta.\n\nIf a faster inbox is what you need, one of the two above will serve you better than we will, and Superhuman in particular has a decade of polish we do not. If the problem is that work arrives in six places and falls through the gaps between them, that is the problem we picked.\n\n## Frequently asked questions\n\n### Can you buy Superhuman Mail without the rest of the suite?\n\nNo. Mail is included from the Business plan upward, at $33 per member per month billed annually or $40 monthly. The Free and Pro plans include Grammarly, Docs and Go but not Mail.\n\n### Is Slashy cheaper than Superhuman?\n\nYes, at list price. Slashy is $25 per user per month billed annually, or $30 on monthly billing. Superhuman Business, the cheapest plan that includes Mail, is $33 billed annually or $40 monthly. Whether the gap is worth it depends on whether you would use Grammarly and Docs, which come with that price and are not part of Slashy.\n\n### Do either of them work with Outlook?\n\nNeither publishes a provider list on its homepage or pricing page. Ask both directly before buying if you are on Microsoft 365.\n\n### Can you try them before paying?\n\nSlashy offers a seven-day trial and requires a credit card to start it. Superhuman has a free plan, but it does not include Mail, so it does not let you evaluate the inbox.\n\n### Which has better security credentials?\n\nSuperhuman publishes more: SOC 2 Type 2, SAML SSO, SCIM, audit logs, data loss prevention and BYOK encryption across its tiers. Slashy lists SSO, SCIM and a security review package at Enterprise without publishing the underlying certifications.", "url": "https://wpnews.pro/news/slashy-vs-superhuman-in-2026", "canonical_source": "https://www.thisandthat.chat/blog/slashy-vs-superhuman/", "published_at": "2026-08-05 00:00:00+00:00", "updated_at": "2026-08-05 20:14:07.748308+00:00", "lang": "en", "topics": ["ai-products", "ai-tools", "artificial-intelligence"], "entities": ["Superhuman", "Slashy", "Grammarly", "Docs", "Go"], "alternates": {"html": "https://wpnews.pro/news/slashy-vs-superhuman-in-2026", "markdown": "https://wpnews.pro/news/slashy-vs-superhuman-in-2026.md", "text": "https://wpnews.pro/news/slashy-vs-superhuman-in-2026.txt", "jsonld": "https://wpnews.pro/news/slashy-vs-superhuman-in-2026.jsonld"}}
