# Push notifications > Send announcements to attendees' phones, now or at a scheduled time, to everyone or to chosen groups. Source: https://help.highbar.ai/docs/run-your-event/push-notifications Audience: event organizers, working in the Highbar dashboard Push notifications put a short message on attendees' lock screens and in the app's **Notifications** screen. Use them for things people need to act on: a room change, a keynote about to start, lunch being served, a prize draw. You'll find **Push notifications** in the event sidebar after launch, in the **Event app** group. The Overview page also has a **Push Notifications** quick link. You can also notify attendees when you post an announcement: turn on **Send push notification** on a post in the [activity stream](https://help.highbar.ai/docs/run-your-event/community/activity-stream). ## Send a notification On the **Push Notifications** page, click **Push notification**. ![The empty Push Notifications page saying Add first push notification, with a Push notification button in the middle and another at the top right.](https://help.highbar.ai/images/run-your-event/push-empty.webp) Under **Send to**, choose **All attendees**, or **Specific recipients** to pick tags or individual attendees. Write a **Title** (up to 40 characters) and a **Message** (up to 120 characters). Keep it to one point: most phones cut off longer text. ![The Push notification drawer with Send to set to All attendees, the Title Welcome, the Message Welcome to Horizons!

Then click **Send now** or **Schedule**. To finish later, click **Save draft**. ![A second notification, Keynote Sessions, linked to the session The Future of Hybrid Events, with an arrow pointing to Send set to Scheduled time, a Date of November 18, 2026, a Time of 7:36 pm, the Timezone Pacific Time, and the Schedule button.](https://help.highbar.ai/images/run-your-event/push-scheduled.webp) ## Track what you've sent The Push Notifications page lists every notification with its status (**Draft**, **Scheduled**, **Sending**, **Sent** or **Failed**) and its **Audience**. Two columns show how it landed: - **Delivered**: devices reached. One person can have several devices, so this can be higher than the number of people. - **Opened**: attendees who opened it in the app. ![The Push Notifications list with two notifications: Keynote Sessions, linked to a session, for an audience of 2 on Nov 18, marked Scheduled with an edit button, and Welcome, sent on Nov 4 to 1 attendee, Delivered 1, Opened 0 (0%), marked Sent.](https://help.highbar.ai/images/run-your-event/push-list.webp) A notification you saved with **Save draft** is marked **Draft**, with no date until you send or schedule it. Click the pencil next to a draft or scheduled notification to edit it, change its schedule or delete it. A scheduled one shows when it's due, and you save changes with **Update schedule**. If a notification shows **Failed**, open it to see how many devices it reached, then click **Send again**. Sending it again notifies the whole audience, including people who already got it. ![The Push Notifications list with a Schedule change notification linked to a session, with no date, and an arrow pointing to its Draft status and edit pencil, above the scheduled Keynote Sessions and the sent Welcome.](https://help.highbar.ai/images/run-your-event/push-draft.webp) ## Who receives notifications A push reaches attendees who have allowed notifications from the app. Some never will, and on iPhones the app has to be installed to the home screen first. Everyone, including those without push turned on, still sees your notifications in the app's **Notifications** screen the next time they open it. To reach as many phones as possible: - Ask attendees to install the app and allow notifications early. The [attendee guide to notifications](https://help.highbar.ai/docs/attendees/notifications) walks them through it, including how to turn notifications back on if they blocked them. - Mention notifications when you share the app link: "Turn on notifications so you don't miss room changes." ## Send them well - **Fewer is better.** Two or three a day is plenty. Attendees who get too many turn them off for good, and then your urgent message doesn't arrive. - **Time them.** Schedule notifications for just before sessions start or at breaks, not in the middle of a keynote. - **Make them actionable.** Link to the session, sponsor or speaker the message is about. - **Target when you can.** Use **Specific recipients** with tags (speakers, VIPs, booth staff) for messages that only matter to some people.
