The one.com Mail app lets you access and manage your one.com email from your phone. You can read and send emails, manage your inbox, and add multiple email accounts in one app.

Logging in to the one.com Mail app

When you log in to the one.com Mail app, your email account is saved in the app, so you don't need to enter your login details every time you open it. You can add and use multiple email accounts in the same app.

If you are logged out of an account, it will remain listed in the app. Simply select the account and enter your password to log in again.

If you log in for the first time:

1. Open the one.com Mail app.
2. Log in using your full email address and password.
3. Tap the Log in button.

Tip: When logging in, you can choose to save your credentials securely on your device. This means you won't need to enter your password again the next time you log in.

Managing push notifications

You can receive push notifications on your device when you get new emails in the one.com Mail app.

Allow notifications on your device
To receive notifications, you must accept the notification permission request in the app or via your device settings. If you don’t allow notifications, the app cannot send alerts about new emails.

How often does the app check for new emails?
The app checks for new emails approximately every 5 minutes. This means there may be a delay of up to around 5 minutes before you're notified about a new email. You'll receive a separate notification for each email account that has new messages.

Checking for new emails when opening the app
When you open the app, we immediately check for new emails again. Unread emails are marked with a red dot, making them easy to spot in your inbox.

While you're in the inbox, tap on the magnifying glass icon to reveal the search bar. It'll appear near the top of the screen. Start typing to find specific emails by sender, subject, or keyword.
