Admins can configure up to three reminders to be sent to end users when their messaging conversation becomes inactive. Configuration options for inactivity reminders are part of the capacity release settings in Admin Center.

Note: For accounts created after May 19, 2025, the capacity release and inactivity reminder settings are turned on by default. Accounts created before this date need to turn on automatic capacity release before they can configure these settings.

About inactivity reminders

For most accounts, inactivity reminders are turned on and configured by default for the Web Widget, iOS and Android SDKs, and Zendesk-supported social messaging channels. The default configuration sends three reminders with simple message text, in the account’s default language. You can keep these default settings or customize them as needed.

By default:

  • The First reminder is sent after five minutes of end-user inactivity, and updates the ticket’s status to Pending.
  • The Second reminder is sent after another five minutes of end-user inactivity, and does not update the ticket’s status.
  • The Third reminder is sent after one additional minute of end-user inactivity, and updates the ticket’s status to Solved.
  • The messaging session does not end when a ticket becomes inactive.
Consider the following when using inactivity reminders:
  • You must be an admin to configure inactivity reminders.
  • Inactivity reminders are available for the Web Widget, iOS and Android SDKs, and Zendesk-supported social messaging channels.
  • It can take up to 10 minutes for updates to the inactivity reminder setting to begin working.
  • If an AI agent is in use, inactivity reminders are sent to end users from that AI agent, and the avatar and bot name associated with it are displayed with the reminder message. If no AI agent is in use, the logo associated with the Web Widget appears with the message.

Configuring inactivity reminders

You can set up inactivity reminders when you configure your messaging capacity release settings, or update the setting at a later date.

To customize your inactivity reminder settings

  1. In Admin Center, click Channels in the sidebar, then select Messaging and social > Messaging.
  2. In the Advanced section, click Capacity release.
  3. Under Remind customers about inactive conversations, select 1 reminder, 2 reminders, or 3 reminders. Subsequent reminder settings are displayed based on this selection.

    To turn off inactivity reminders, select Do not remind.

    Note: If you selected Solved as the ticket status for the initial inactivity period, you will only be able to select Do not remind or 1 reminder.
  4. Select End messaging session after last reminder is sent to automatically end the messaging session when the ticket becomes inactive.
  5. Configure the reminders’ messages, inactivity periods, and ticket status changes as needed:
    Note: You can use dynamic content in reminder messages to automatically translate or customize the messages for end users.
    • First reminder: Enter the message you want to send when the initial inactivity period is reached, or use the default message. This reminder uses the wait time and ticket status configured for the initial messaging capacity release settings.
    • Second and Third reminders (if applicable): Enter a whole number between 1 and 15 for the Wait time after previous reminder in minutes. Enter the message you want to send and the status change you want to apply to the ticket when each subsequent inactivity period is reached. You can select No change, Pending, On-hold, Solved, or a custom status mapped to these ticket status categories.

      Support ticket triggers using the selected ticket status as a condition will fire when the new status is applied.

  6. Click Save settings.
