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.
Mailbutler Smart Assistant
Mailbutler Smart Assistant adds AI writing and email-management tools to Apple Mail, Microsoft Outlook, and Gmail. It drafts messages from keywords or prepares replies using details a user supplies, with controls for format, length, style, tone, and language. It can summarize selected emails, identify to-dos for Mailbutler Tasks, and suggest spelling and grammar improvements to drafts. Mailbutler says the assistant uses OpenAI GPT-4o. Smart Assistant is included in a 14-day trial, then requires a Smart or Business subscription. The separate free Starter plan includes a visible Mailbutler watermark on sent emails. Mailbutler says email subjects and bodies are processed by Microsoft Azure OpenAI Service in the EU, with personal data redacted before submission to the underlying model. It also says backend data is encrypted and that it is ISO/IEC 27001 certified and GDPR compliant. Apple Mail support is listed for macOS Tahoe, Sequoia, Sonoma, and Ventura; mobile apps require iOS 15 or later or Android 7 or later.
