Receiving Trello notifications
When subscribed to a card, you’ll get notifications for…
- All comments from other users
- Adding, changing, and upcoming due dates
- Card moves and archives
- Attachments uploaded to a card
When subscribed to a list or board…
- You’ll get the same notifications listed above, but for all cards in a list or board.
- You’ll also get notifications for all newly created cards
And at any time, you’ll get notifications when…
- You are mentioned in a comment.
- You are added to a card, board, or team.
- You are mentioned in a checklist item.
- One of your boards is closed.
- When someone makes you an admin of a board or team.
Notifications are represented on the Trello site with a bell shaped button in the top right corner. When you have notifications the button turns red. Click on the notifications button to view your notifications. Also, by default you will receive a notification email for any notifications that go unread within Trello.
Due Date Notifications
If you set a due date on a card and you are a member of the card (or subscribed to the card), you will receive a notification about the card twenty-four hours before it is due. Notifications for due dates only occur twenty-four hours before the card is due and if you are not subscribed to the card or have not been added you will not receive a notification.
Notification Emails and Preferences
You can change how often you get notification emails in your "Account" page. You can also set your notification email preferences by clicking the Notifications button in the header and selecting "Change Notification Email Frequency". Options are "Never", "Periodically", and "Instantly." "Instantly" is the default and any unread notifications in Trello are emailed out as soon as possible.
Emails contain a collection of all unread notifications. Email summaries won't include any notifications you've already read on the site. You can reply to individual notifications from within a notification email to add a new comment to the card that is referenced in each notification.
If you’re using Chrome, Safari or Firefox, your browser can generate desktop notifications, an emerging web standard. (At this time, they're not supported in Internet Explorer or Edge.) Just click on your name in the header, and select "Settings" then select “Enable Desktop Notifications…” from the settings page. Now when you get a notification, a small window with the notification will show up in the corner of your desktop. Desktop notifications can also be set in your " Account" page.
If you would like to disable Trello desktop notifications in Chrome & Firefox, while at https://trello.com you can select the lock icon in your browser's address bar and under Permissions change the Notifications permissions to block. To disable Trello desktop notifications in Safari, in the Safari header select "Safari", then "Preferences", then "Notifications." In the notifications tab you will want to find trello.com in the list of websites and select "Deny."
Note: If you have previously denied desktop notifications in Chrome, Firefox, or Safari you may not see the option to enable desktop notifications in your Trello settings page. If this is the case then you can still enable Trello desktop notifications in Chrome and Firefox by selecting the lock icon in your browser's address bar and under Permissions changing the Notifications permissions to allow. In Safari you can enable desktop notifications by selecting "Safari" from the browser's header, then "Preferences", then "Notifications." In the notifications tab you will want to find trello.com in the list of websites and select "Allow."
