In their own words
BlueMail
BlueMail is an email client that brings accounts from multiple providers into a unified inbox. It supports IMAP, Exchange (ActiveSync), POP3, Office 365, Gmail, Yahoo, iCloud, Outlook and other standard providers, and includes offline access and an integrated calendar. Clusters automatically group messages, while People-Centric organization arranges the inbox around people. GemAI can summarize threads, draft replies in the user's voice and rewrite messages for tone, length or clarity. Users can share threads to Slack, Notion and Linear; Messaging Bridge lists Slack, Teams, WhatsApp and SMS. BlueMail says it syncs directly with email providers rather than storing emails on its servers, and encrypts data in transit and at rest, with optional end-to-end PGP encryption. Blue Guard protections include phishing detection, attachment quarantine and pixel-tracker blocking. Apps are listed for Android, iOS, Linux, macOS and Windows.
Mailspring
Mailspring is a desktop email client for Linux, macOS, and Windows, with support for multiple accounts in one inbox. It connects to Gmail, iCloud, Office 365, Fastmail, Outlook.com, Yahoo!, and IMAP/SMTP providers, and indexes email for advanced Gmail-style searches across connected accounts. The client works offline and supports scheduled sending. Its free features include undo send, spell and grammar checking, custom themes, dark mode, and localization. Pro adds read receipts, link tracking, send later, follow-up reminders, templates, contact profiles, snoozing, and mailbox insights. Mailspring connects to mail providers through IMAP and to calendars and contacts through CalDAV and CardDAV, though calendar tools are not included in the app. It can translate drafts into Spanish, Russian, simplified Chinese, French, and German, and offer to translate incoming messages. Mailspring says credentials are kept in the system keychain and email is not processed in the cloud. The free plan is available; Pro costs $8 a month, billed monthly.
