There is no single best AI email assistant for everyone. The right choice depends on whether you want a new email app or want to stay in Gmail and Outlook, whether you need replies written or only mail filtered, and whether an assistant or a team shares your inbox. This page compares InboxManager with five well-known tools using only their general public positioning, so you can pick the one that fits. We make InboxManager, so read it with that in mind and check each product's own site before you decide.
Before comparing names, answer five questions about your own inbox.
Your answers narrow the field quickly. A person who loves keyboard shortcuts and wants a fresh client has different needs from an executive whose assistant drafts replies in Outlook.
The table reflects each product's general public positioning at the time of writing. Features change, so treat any "check their site" as an invitation to look at the current details.

Superhuman is a separate, fast email client built around keyboard shortcuts, with AI writing features, and it connects to Gmail and Outlook accounts. It suits people who want a new, highly polished app and are happy to read mail there instead of in Gmail or Outlook. It costs around 30 USD per user per month, with a Business tier around 40 USD per user per month at the time of writing, check their site for current pricing.
Shortwave is an AI-first email client for Gmail accounts, with AI search, summaries and writing help. It fits Gmail users who want a different interface with AI built into it. It is not for Outlook mailboxes. It costs around 24 to 45 USD per user per month at the time of writing, check their site for current pricing.
Fyxer AI works inside Gmail and Outlook, sorts mail and drafts replies, which makes it the closest in approach to InboxManager. Compare the details that matter to you, such as delegation, shared inboxes and admin controls, on their site. It costs around 22 to 50 USD per user per month at the time of writing, check their site for current pricing.
SaneBox has a long track record of filtering email into folders so less important mail stays out of your inbox, and it works with many mail providers. It is a good fit if filtering is all you want. It does not focus on writing replies. It costs around 7 to 36 USD per month depending on the plan at the time of writing, check their site for current pricing.
Front is a shared inbox platform built for teams, especially customer support and operations, where many people answer mail from shared addresses and work in Front itself. It suits teams that need help desk style workflows. It is priced per seat on team plans, check their site for current pricing.
InboxManager is built for the person who owns the inbox and the people who help them. It works inside the Gmail or Outlook you already use, writes reply drafts in your voice and never sends anything without your approval, because no auto-send setting exists. Every plan includes an assistant seat, Gmail and Outlook mailboxes can be mixed on one account, and shared inboxes for info@, sales@ and support@ arrive from Plus upward.
Being honest helps you choose well. If you want to leave Gmail and Outlook behind for a new client with its own interface, Superhuman or Shortwave are built for that. If you only want filtering and never want AI to write anything, SaneBox is focused on exactly that. If you run a large support team that needs a full help desk workflow, Front is designed for it. InboxManager fits best when you want to stay in Gmail or Outlook, want drafts written for you, and work with an assistant or a small team.
Per user prices are hard to compare because plans include different things. InboxManager Starter costs 24 USD per month billed yearly, or 49 USD month to month, and covers one owner, one assistant and two mailboxes. To compare, price the same setup elsewhere: two people and two mailboxes, with drafting and delegation. Every InboxManager plan and its monthly limits are on the pricing page.
Several tools connect to both. The difference is where you read your mail. InboxManager and Fyxer AI work inside Gmail and Outlook themselves, while Superhuman connects both kinds of accounts to its own client. Shortwave is for Gmail only.
InboxManager saves every reply as a draft and has no automatic sending setting, so a person always presses send. Other tools describe their own approval options on their sites.
Not with every tool. InboxManager writes labels, folders, categories and drafts into your mailbox, so you keep using Gmail or Outlook on the web, desktop and phone. Tools built as their own clients ask you to read mail in their app instead.
Yes, once. The home page has a demo where you paste an email and see how InboxManager sorts it, summarizes it and drafts a reply. There is no free plan, paid plans start at 24 USD per month billed yearly.
If staying in Gmail or Outlook, getting drafts in your voice and approving every send sounds right, connect your mailbox and see it work. Read how inbox management works or compare email management software options for business.
