ChatInbox: Email by Sender

About this app

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.

New • Relationship insights (Settings → optional): open a contact's details to see how the two of you actually relate — who usually reaches out first, typical reply speed, when you tend to talk, quiet stretches and reconnections, plus a tappable chart of your message rhythm over time. It's built entirely on your device from who-and-when only — never the contents of your mail. Improvements • Tapping a contact now opens an unread message fully expanded, so you can read it straight away instead of tapping "Expand" first. • Gmail messages now show the same time gmail.com does. Some mail from bulk senders could be off by a few minutes. Fixes • Fixed conversations in the chat list showing a nonsense date like "0001-01-01" instead of the real time of the last message.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
