About Unibox – Email by sender

Unibox groups your emails by sender. Find past messages, conversations and attachments under the relevant contact. See what you've written to each other. Under each contact, you'll see both received and sent emails. Whether you're arranging a meeting, following up with a question or sharing new documents, your correspondence stays together even when the subject changes. Find the file without first searching for the email. Unibox shows you all attachments from a sender in one place. Find documents and photos from different messages without first tracking down the email they came with. Clean up without opening every email. Delete or move all emails from the same sender together. This is useful for newsletters, automated confirmations and other regular emails. You can still manage individual emails separately. Reply with your previous emails in view. Read and write in the same window. While composing a reply, you can refer to earlier messages without switching between separate windows. A conversation stays together, even when several people are involved. Open a conversation with multiple participants from your email history. You'll see the messages in that conversation separately from other topics. Keep multiple inboxes in view. Unibox brings emails from all your accounts together in one view. See your personal and work email accounts in the same place. Use your existing email accounts. Unibox supports IMAP accounts, including iCloud, Gmail (with an app password), Outlook.com and Microsoft 365, as well as accounts on your own mail servers. Exchange accounts can be used if IMAP is enabled. Connect directly to your email provider. When sending and receiving email, Unibox connects directly to your email provider. Your emails are not routed through Unibox servers. Login credentials are stored locally on your device.
