Superhuman alternative for Gmail and Outlook that keeps you in your own inbox
InboxManager is a Superhuman alternative for people who want AI help with email without moving to a new email app. It works inside the Gmail or Outlook you already use: new mail is sorted into five lanes, long threads get a short summary and reply drafts in your voice wait in your Drafts folder. Superhuman is a separate, keyboard-first email client billed per member, from 25 USD a month on yearly Starter and 33 USD on yearly Business. InboxManager charges one price per workspace, from 24 USD a month billed yearly for an owner and an assistant.

InboxManager and Superhuman side by side
Superhuman and InboxManager both use AI on your email, but they sit in different places. Superhuman replaces the app you read mail in. InboxManager works on the mailbox itself, so the results show up in Gmail, Outlook and their phone apps. Superhuman figures come from the Superhuman plans page and help center in October 2026, InboxManager figures from our own pricing page.
| What you compare | InboxManager | Superhuman Mail |
|---|---|---|
| Where you read mail | Your own Gmail or Outlook, web, desktop and phone | The Superhuman app on Mac, Windows, web, iPhone and Android |
| Accounts it works with | Gmail, Google Workspace, Outlook.com and Microsoft 365 | Gmail, Google Workspace and Microsoft 365 |
| How you pay | Per workspace, Starter 24 USD a month billed yearly | Per member, Starter 300 USD a year and Business 396 USD a year |
| Monthly billing | Starter 49 USD, Plus 149 USD for up to 5 people | Starter 30 USD and Business 40 USD per member |
| AI reply drafts prepared before you open a thread | Every plan | Auto Drafts on Business and Enterprise |
| AI sorting of new mail | Five lanes on every plan, rules in plain English | Split inbox, Custom Auto Labels on Business |
| Assistant working in your mailbox | Included on Starter, with approval of sensitive replies | Shared conversations and team comments |
| Shared inboxes for info@ or support@ | From Plus, with assignment and collision detection | Not a core feature |
| Keyboard shortcuts for everything | Uses Gmail or Outlook shortcuts | The core of the product |
| CRM next to the thread | Not included | HubSpot and Salesforce on Business |
| Sends email by itself | Never, every draft waits for you | You send from the app |
What a team of five pays on each tool
Superhuman is priced per member, so the bill grows with every person who needs access. Here is the same five-person team at list prices.
- 01 Superhuman Business, billed yearly, 5 members at 396 USD a year comes to 165 USD a month
- 02 Superhuman Starter, billed yearly, 5 members at 300 USD a year comes to 125 USD a month
- 03 Superhuman Business, billed monthly, 5 members at 40 USD comes to 200 USD a month
- 04 InboxManager Plus, billed yearly, up to 5 people for 74 USD a month in total
- 05 InboxManager Plus, billed monthly, 149 USD a month in total
Plus includes 10 connected mailboxes, 20,000 triaged emails, 2,000 reply drafts and 900 thread summaries a month, plus two shared inboxes. For one person the difference is small: Superhuman Starter billed yearly is about 25 USD a month and InboxManager Starter is 24 USD with an assistant seat included. The gap opens up with the second, third and fourth person, and when the auto drafting you want sits only in Superhuman Business. We break the numbers down further in our Superhuman pricing guide.
Why a cheaper Superhuman alternative does not mean a weaker one
Most of what Superhuman charges for is the app: a fast, polished client built around shortcuts. If you already like Gmail or Outlook, you are paying for a second interface you will not use much. InboxManager puts the money into the work an inbox creates, sorting, summaries, drafts, follow-ups and handing mail to an assistant, and leaves the reading to the app your company already pays for.
When Superhuman is the better choice
An honest answer saves you from switching twice. Superhuman is a very good product, and for some people it beats InboxManager.
- 01 You answer a high volume of email yourself and want the fastest keyboard-driven client there is
- 02 You want read statuses, snippets and a reminder system built into the app you write in
- 03 Your sales team wants HubSpot or Salesforce records next to every thread
- 04 Your company would buy Grammarly anyway, and the Superhuman suite bundles it with Mail on Business
If you would rather keep Gmail or Outlook and have less email land on you in the first place, InboxManager is the better fit, especially once an assistant or a team shares the inbox.
A Superhuman alternative for Outlook and Microsoft 365
A lot of people searching for Superhuman for Outlook really want one thing: AI help that lives in Outlook itself, because that is where the company calendar, rules and compliance setup are. Superhuman connects to Microsoft 365 accounts, but you read the mail in the Superhuman app. InboxManager connects through Microsoft Graph with Microsoft sign-in and does its work in the mailbox. Important and Needs reply stay in your Inbox with a color category, newsletters and cold pitches move to their own folders and drafts land in Drafts, so you see everything in Outlook on the web, on Windows and Mac and on your phone. Focused Inbox and your existing rules keep working, and if your tenant needs admin consent, IT approves InboxManager once in Microsoft Entra. The full setup is on the Outlook AI assistant page.
A Superhuman alternative for Gmail and Google Workspace
In Gmail, InboxManager uses labels instead of folders, and drafts appear in the thread exactly where you would start typing a reply. You keep Gmail's search, filters, add-ons and the mobile app your team knows. Details are on the Gmail AI assistant page.
What you get that a faster email client does not give you
Superhuman makes the person at the keyboard faster. InboxManager is built so that fewer emails need that person at all.
- 01 Five lanes for every new message: Important, Needs reply, Waiting, Newsletters, and Spam and cold pitches
- 02 AI reply drafts written in your voice from your past sent mail, ready before you open the thread
- 03 Thread summaries that turn a long chain into a few lines you can read in seconds
- 04 Follow-up reminders for threads in Waiting that went quiet, with a nudge draft ready
- 05 Assistant delegation so an executive assistant works in your mailbox while you approve what matters
- 06 A daily briefing email with what needs a reply and who owes you an answer
How to switch from Superhuman to InboxManager
Nothing moves when you switch, because your mail never lived in Superhuman. It stayed in your Gmail or Microsoft 365 account the whole time.
- 01 Paste a real email into the demo at the top of this page to see the lane, summary and draft InboxManager produces
- 02 Create your InboxManager account and connect Gmail or Outlook with Google or Microsoft sign-in
- 03 Write two or three rules in plain English for the senders that matter most, such as "invoices from our accountant go to Important"
- 04 Go back to reading mail in Gmail or Outlook, and check that your drafts and lanes are there
- 05 Cancel Superhuman in its settings and remove its access in your Google Account or Microsoft account security page
What is the best alternative to Superhuman?
The best alternative depends on why you are leaving. If you want to stay in Gmail or Outlook and have AI sort mail and prepare drafts, InboxManager or Fyxer AI fit. If you want another fast Gmail client, Shortwave is the usual pick. For shared team inboxes, InboxManager Plus or Front.
Is there a cheaper alternative to Superhuman?
Yes. For a team, InboxManager Plus covers up to five people for 74 USD a month billed yearly, while five Superhuman Business seats cost about 165 USD a month billed yearly. For a single user the prices are close, and InboxManager Starter adds an assistant seat at 24 USD a month.
Does Superhuman work with Outlook?
Superhuman works with Microsoft 365 accounts as well as Gmail and Google Workspace, but you read and answer that mail in the Superhuman app, not in Outlook. If you want the AI help to show up inside Outlook itself, use an assistant that works on the mailbox, such as InboxManager.
Is Superhuman worth the money?
Superhuman is worth it for people who process a lot of email themselves and value speed and shortcuts above everything else. It is less worth it if you like Gmail or Outlook, need an assistant in your inbox or pay for several team members, because each one is a separate seat.
Can I use InboxManager and Superhuman together?
Yes. InboxManager works on the mailbox, so its labels, folders and drafts also appear in Superhuman when it shows your Gmail or Microsoft 365 account. Some people keep Superhuman for writing and let InboxManager do the sorting and drafting, then decide which one they still need.
Try the Superhuman alternative on your own email
