Why Instant Push matters
Speed you can feel.
For time-critical email (alerts, approvals, two-factor codes, breaking news), every second matters. We measure and tune the push pipeline relentlessly.
Works on every account
Personal or work, Gmail, Outlook, Exchange or your own server: Instant Push works with them all.
Battery-friendly
Engineered to preserve battery life through smart connection pooling and adaptive backoff.
Cross-device awareness
A push on your phone instantly silences the same notification on your laptop. Less noise across devices.
How it works
Built on open protocols.
No proprietary servers. No central intermediary. BlueMail talks directly to your provider using the modern push standards each one supports.

BlueMail fetches the message and surfaces it as a notification within milliseconds.
