How to test a notification channel

Before relying on a delivery channel, run a test to confirm it works.

When it is useful

  • You set up a new channel (Telegram, Viber, browser).
  • You want to verify delivery before use.
  • You see errors when notifications are sent.

What to know

  • A test notification is sent only through the selected channel (not all channels).
  • Tests do not change your notification settings.
  • Linked channels — for Telegram/Viber you must finish linking before testing.

Before you start

  • The channel is configured (for Email/Telegram/Viber — by an administrator).
  • The channel is connected (for Telegram/Viber — linked to your profile).
  • You are logged in.

Steps

1. Open notification settings

Go to Profile → Notifications → Channels tab.

2. Find the channel

Scroll to the channel:

  • Bell notifications
  • Banner notifications
  • Email
  • Telegram
  • Viber
  • Browser notifications

3. Click Test

Click Test next to the channel.

4. Check the outcome

Depending on the channel:

  • Bell — appears in the bell menu
  • Banner — toast in the top-right corner
  • Email — test arrives at your profile email
  • Telegram — test arrives in Telegram
  • Viber — test arrives in Viber
  • Browser — a system browser notification appears

5. Read the result message

The app shows:

  • Success — “Test notification sent via {channel}”
  • Error — details (for example, “Channel not connected”)

Result

After a successful test you can:

  • Use the channel for notifications
  • Be confident delivery works
  • Catch issues early
