Postman is an email client for Android. Connect your IMAP/SMTP accounts and read, organize, and send mail from your device.
What you can do
Add one or more mail accounts and sync with your provider
Read messages with a clean reading experience; work with attachments where supported
Compose and send email over your configured SMTP server
Keep mail data cached locally for faster access and offline-friendly use
Privacy & security
Account passwords are stored encrypted on your device (Android Keystore when available)
The app talks to your mail servers — not a separate “Postman cloud” for your mailbox
No third-party analytics SDKs in the current app build
Two ways to work
Light mode — a focused inbox-style flow
Full mode — browse folders and messages in depth
Postman is built for people who want a straightforward mail app and control over their own provider and data on the phone.
Note: “Postman” here is an independent email app and is not affiliated with other products that use the same name.
