Unibox – Email by sender

Conversations & attachments

Overview

Features & Capabilities

Unibox makes email easier to find by grouping messages by sender. Browse received and sent emails, keep conversations together, and access all attachments from a contact in one place. Reply while viewing previous messages, manage individual emails or clean up messages in bulk, and keep multi-person conversations separate by topic.

Bring multiple inboxes into one view while using your existing IMAP accounts, including iCloud, Gmail, Outlook.com, Microsoft 365, and supported mail servers. Unibox connects directly to your email provider, without routing messages through Unibox servers, and stores login credentials locally on your device.

User Reviews

Users praise Unibox for sender-centric threading, easy access to all messages and attachments per contact, and efficient bulk inbox cleanup. They value the clean UI and cross-account organization. However, the app is frequently described as abandoned with little developer support, struggles with modern provider security (Gmail 2FA/Advanced Protection), unreliable push/sync, and various stability issues, which undermines its usefulness for current, security-conscious users.
Pros
  • Sender-centric threading that groups all emails from a contact and shows attachments in one place.
  • Efficient bulk actions to delete or trash many emails at once (from a single sender or multiple senders).
  • Clean, simple, visually appealing interface with strong organization that boosts productivity.
  • Privacy-focused design, including not storing passwords on a central server and an emphasis on security.
  • Cross-account aggregation and the ability to manage or view specific accounts or group emails by contact.
Cons
  • App appears abandoned with long gaps between updates and little to no response from the developer.
  • Compatibility issues with modern providers (e.g., Gmail 2FA/Advanced Protection) and frequent authentication/setup failures.
  • Push notifications are often missing or unreliable, with syncing problems.
  • Stability and performance problems such as buggy scrolling, slow loading, and inconsistent behavior.
