ByteMail

It doesn’t bundle a browser engine and supports Gmail, iCloud, Outlook, Microsoft 365, Yahoo, Fastmail, and other IMAP email providers, consolidating multiple accounts into a single, fast, unified inbox. The software offers conversational and classic email views, instant cross-account search, attachment search, smart tags, unread filtering, automatic rule archiving, post-processing, scheduled sending, retractable sending, email alerts, and multi-account signatures. It connects directly to your email service provider, with credentials stored in macOS Keychain; emails, contacts, and usage data do not pass through bytemail servers. Tracking pixels and link tracking parameters are cleaned up, external images are loaded on demand, and it can identify spoofed domains, brand impersonation, and suspicious links. The software also supports local summaries, smart replies, and rewrites, and connects to AI applications like Claude, Codex, and Cursor via MCP to process content from specified accounts upon user confirmation.
