In a traditional inbox, emails from the people who matter most get buried under everything else. ChatInbox puts people first — grouping every message by contact, so each person's conversation is always one tap away.
Tap a contact. See everything you've ever exchanged — messages, attachments, history — all in one clean, chat-style view. No more hunting through a chronological pile of unread mail to find that one message from your client, your accountant, or your kid's school.
If you've ever wished email worked like iMessage — but for every account, every provider, all in one place — ChatInbox is what you've been looking for.
CONTACT-CENTERED INBOX
Every email is grouped by sender. Your contact list shows the most recent conversation first, each person appearing only once. Open a contact to see your full history, displayed as a natural back-and-forth conversation.
UNIFIED ACCOUNTS
Connect Gmail, Outlook, iCloud, and any IMAP account. All your email, all your contacts, one inbox — synced across iPhone, iPad, and Mac.
SMART CONTACT GROUPING
ChatInbox automatically groups related contacts — airlines, hotels, online shopping, subscriptions — so you can manage entire categories of email at once.
CALENDAR EMAIL FILTER
Browse your inbox by date using the built-in calendar view. Find any message from any day without searching.
VISUAL ORGANIZATION
Tag and organize emails on a Kanban board. Track what needs attention, what's waiting for a reply, and what's done.
REMINDERS & NOTIFICATIONS
Set custom reminders on any email. Get notified about messages that matter and let the rest wait.
MARKDOWN COMPOSER
Write polished emails with built-in Markdown formatting. Style text clearly without wrestling with toolbars.
PRIVACY FIRST
Your emails stay on your devices. ChatInbox connects directly to your mail servers — no third-party servers, no data mining, no tracking.
Previously used Unibox and miss email grouped by sender? ChatInbox carries that vision forward — rebuilt from the ground up for modern Apple platforms, with features Unibox never had.

This is the type of app I have been looking for for a long time. An app to arrange my emails by sender, similar to text messages. It helps me bulk filter importance based on where emails are coming from. My only complaint right now is lack of support for easier bulk actions/swipe features/keyboard shortcuts. I want to be able to swipe to delete messages or sender folders. Also be able to use things like Cmd-A to set all messages from a sender. My main use of this app is to easily bulk delete and unsubscribe from senders I don’t care about, so I am really glad an app like this exists, I just want more ease of use features :)
Nice!

My wife and I had been using Unibox for years, but since last big Apple Update it is broken and it does not look like developers will be updated it anymore. My wife found this one to replace Unibox since we like chat style and she mentioned it to me, I was skeptical because it was so new and only had two written reviews. I tried it anyways and to my surprise I like it very much. It is nice to have the chat contact feature back! I decided to get in on their limited low price deal - Premium Lifetime. I recommend it for those coming from Unibox and it has better features than Unibox. I also recommend it for anyone who likes the personal chat style like Messages, by the way you can easily tap/click on icon and it will switch to old style email layout if that is what you prefer and then just as easily switch back. I am using both of their Apps for iPhone and Mac. It is simple to use and appealing to the eyes on both.

Great for getting through bulk
Chris - Software Dev
This app more than any other I’ve found lets me deal with email the way I want to, which is by sender rather than by individual email. So much easier to go through all the mail from a single company rather than to constantly context switch between lots of things. Also makes it so much easier to deal with all the bulk email garbage you get when you can just delete everything from a single sender in one fell swoop. There are a few bugs here and there, but I’m willing to forgive those small things for the power it gives me to get through email the way I want to.
Got potential

I love how the app separates the subject lines yet keeps things grouped by the sender of the email. It makes it much easier to follow threads. I deal with a lot of group emails in my business and community HOA. However I can’t figure out how to attach an image from my iPhone library. It just connects to my files. Also I love the idea of groups, however I don’t see the point as I can’t attach the email addresses in the group to an email. It would be great to click on the group and start an email with all the addresses in the group. I’d pay for the premium if these fixes were made. Especially attaching an image, not being able to do that is a deal breaker for me.
Developer Response
Thank you for your valuable suggestions, which have helped us better understand our users' needs and improve our product. We've taken your ideas—direct messaging to groups and support for photo attachments—seriously. Both features have been implemented in version 1.4.1, which we've submitted to the App Store for review. It should be available for update within 1-2 days. Should you have any more observations or areas you believe could be improved, please don't hesitate to share. Thanks again!
New Features
- New bottom tab bar: a simpler way to get around — swap the side menu for a familiar bottom bar with Inbox, Folders, Calendar, Tags, and Settings, plus a redesigned Folders tab with search, per-account filtering, and a Snoozed view.
- Calendar, rebuilt for iOS: a clean Apple Calendar–style day view with a week strip you can swipe through, an unscheduled drawer, long-press anywhere to add an event, and drag to reschedule.
- Add to Calendar from a message: turn any email into an event or to-do with one tap, and see a badge on messages that already have something scheduled.
- Snoozed messages stay in view: instead of disappearing from the thread, snoozed messages now show up so you don't lose the context.
- Smarter search: type multiple words and only results matching all of them come back, or use quotes for exact phrases. Search now ignores trash and spam, just like your inbox does.
- Attachment previews: see thumbnails for documents and other files right in the chat list — not just images.
- Refreshed Folders banner: a cleaner, full-width filter row at the top of folder views.
- Polished Tags: a more native look and smoother drag-and-drop on the kanban board.
Improvements and Fixes
- Mail stays in sync: a long-standing issue where syncing would silently stop has been fixed, along with several causes of stuck or frozen accounts — including iCloud accounts that wouldn't load message bodies.
- Stuck messages and attachments now self-recover: if a message body or attachment failed to load, it now retries automatically instead of staying stuck.
- Gmail accounts recover better after long gaps without opening the app.
- No more unread badge flicker when you open a feed — the newest message opens as read immediately.
- Back-to-Top button redesigned as a smaller round button that's easier to tap.
- Avatars: fixed a bug where colleagues at the same company would briefly show the wrong logo after restarting the app.
- Fewer battery drains: stopped a case where a spinner would keep animating invisibly and use CPU.
- Cleaner conversations: stray "references" to threads no longer clutter your chat list.
- Small polish to the mail list so the first section header no longer sits flush against the top edge.
