How to Create In-App Notifications Users Want to See

An in-app notification can help a user complete the task already in front of them—or interrupt it at exactly the wrong moment. The difference comes down to context: who sees the message, what triggered it, what action it requests, and whether the user can dismiss or revisit it.

This guide shows product, growth, and lifecycle teams how to make those decisions, turn them into a testable notification, and evaluate the result without confusing an in-app message with a mobile push notification.

What Is an In-App Notification?

An in-app notification is a message displayed inside a web or mobile application while the user is using it. It can announce a change, explain a feature, confirm an account event, or prompt a relevant next action. Common formats include banners, modals, tooltips, hotspots, and messages saved in an in-app notification center.

This article focuses on contextual messages rendered in the app interface. A persistent inbox is related, but it is a separate component that stores messages for later review. A mobile or web push notification is different again: it is delivered through an operating system or browser notification channel and can reach a user outside the active app experience.

For a broader introduction to the channel, including additional use cases and examples, read EngageLab's guide to in-app notifications.

How Do In-App Notifications Differ from Push Notifications and In-App Inboxes?

These channels can work together. A push notification might bring a user back for an urgent account update, while an in-app banner explains what changed and links to the relevant screen. Do not assume, however, that choosing a push provider automatically gives your app a custom modal, tooltip system, or persistent inbox. Those experiences may require a separate product module or app-side development.

Which In-App Notification Format Fits the Message?

These in-app notification examples show how to match the format to the user's task. Choose the least disruptive option, with a clear trigger and destination.

Onboarding Modal: Invite a Teammate

After a new user creates their first project, show a modal inviting them to add a teammate. Use “Invite teammate” as the CTA and open the member-invite panel when clicked. Let users skip this optional step, and measure completed invitations rather than button clicks.

Feature-Announcement Banner: Introduce a Relevant Change

Use a banner for an update that deserves attention but should not block the current task. Target users with access to the feature, trigger it on a related screen, and link directly to the feature or a short explanation. Keep it unobtrusive and stop showing it once the user has tried the feature.

Account-Update Modal: Request a Necessary Action

A modal is appropriate when the user must acknowledge or resolve something before continuing, such as an expired payment method. A complete specification could look like this:

• Audience: workspace owners whose saved payment method has expired.

• Trigger: the first dashboard visit after the expiration is confirmed.

• Format: modal with a clear close or “Remind me later” option when the action is not immediately mandatory.

• Message: “Update your payment method to prevent an interruption to your workspace.”

• CTA and destination: “Update payment method,” opening the billing screen.

• Success measure: completed payment-method update among users who saw the modal.

Use a persistent inbox entry when the user may need the same update later. A modal alone is a poor archive; an inbox alone may be too easy to miss for an urgent task.

How to Create an In-App Notification Step by Step

The same core workflow applies whether you use a messaging platform or build the experience in-house: define the goal, prepare the integration, create the message, configure who sees it and when, then test and measure the result. The steps below use the EngageLab AppPush Portal as a practical console example so you can see how those decisions translate into an actual campaign.

Before opening the console, create an AppPush project, register a test device, and complete the SDK integration. EngageLab's current In-App message documentation states that the feature supports Android and iOS, requires SDK version 4.5.0 or later, and is created in the web Portal rather than through the Push API. The Portal controls the message, target users, eligible page, timing, and display settings; your app supplies the identifiers, segments, page paths, deep-link destinations, behavioral data, and conversion events those controls depend on.

1. Define the Goal, Audience, and Trigger

Start with one action that helps the user. For example, “Help a new workspace owner invite the first teammate” is more useful than “increase engagement.” The audience is a new workspace owner, the trigger is reaching the project dashboard without a teammate, the CTA opens the invite panel, and the success event is a completed invitation.

In EngageLab, you can later select all registered users, a saved segment, or specific Registration IDs. Behavioral triggers and exclusions require the app or connected data system to identify the relevant state—for example, excluding anyone who has already invited a teammate or completed the requested action.

2. Open the In-App Creation Screen

In EngageLab, sign in, open the AppPush project, select Push in the main navigation, and choose In-App from the Push menu.

3. Choose a Format and Write the Message

Choose the least disruptive format that can complete the user's task, then write the message and CTA around that action. In EngageLab, enter a message name, select Android or iOS, and choose an interstitial, banner, full-screen model, or custom HTML template. Add the image, title, body, and primary or secondary buttons. Button actions can use a URL, deep link, permission prompt, or dismiss action.

State what changed, why it matters now, and what the user should do next. A specific CTA such as “Invite teammate” or “Update payment method” is more useful than “Learn more.” Keep a prominent close control on promotional messages and make sure the destination already exists in the app.

4. Select Your Audience and Display Settings

Translate the audience and trigger from Step 1 into targeting and display rules. In EngageLab, choose all registered users, a saved user segment, or specific Registration IDs. Then decide whether the message can appear on any page or only on a specified app page. The page path and deep-link behavior must match the routes implemented by your app.

Select immediate or scheduled delivery. Advanced settings let you delay the popup, use timed disappearance or manual close, and set a display-validity period. Use these controls to prevent a stale message from appearing after its context has passed. Any repeat limits, completed-action suppression, or priority rules not provided by the campaign screen must be enforced through your audience logic or app implementation.

5. Test, Send, and Review Results

Every implementation should be tested in the live app before the audience expands. In EngageLab, select Registration ID under Target Users, enter the test device's Registration ID, and click Send Preview. Then open the live app and check the eligible page, message content, buttons, destination, close behavior, and expiration. After it passes the checklist in the next section, switch to the intended audience, confirm the sending time and advanced options, and submit the production send.

Use EngageLab's message statistics to review the available delivery, impression, and click data. Connect those metrics to the conversion event in your own analytics so that a click is not mistaken for completion of the intended task.

How Should You Test and Measure an In-App Notification?

Test the eligibility logic and the live user experience across the conditions that can change the outcome.

• Eligible and ineligible users: confirm that the intended segment sees the message and excluded users do not.

• First and repeat triggers: verify initial display, repeat limits, cooldowns, and completed-action suppression.

• Dismissal: test close, escape, back-button, outside-click, and “remind me later” behavior where applicable.

• CTA destination: check authentication state, deep links, back navigation, and unavailable destinations.

• Devices and versions: test supported screen sizes, orientations, operating systems, browsers, app versions, languages, and text expansion.

• Accessibility: check keyboard focus, screen-reader labels, contrast, readable motion, and zoom behavior.

Measure the funnel in stages. Eligible users met the targeting rules; displays or impressions confirm that the UI appeared; clicks show CTA interaction; dismissals show that users closed it; and conversions record the intended action, such as completing setup. Use the correct denominator for every rate, and make sure the final action is instrumented before launch.

FAQs

• 1

  Do in-app notifications require operating-system permission?

  A message rendered as part of your app interface generally does not use the operating system's push-notification permission. That does not remove privacy, consent, preference, or accessibility obligations related to the data and experience. Push notifications delivered through an operating system or browser follow their own permission and platform rules.
• 2

  How often should in-app notifications appear?

  There is no universal frequency. Define limits by message urgency, user behavior, dismissal history, and the number of competing prompts. Stop showing a notification after the user completes its goal, and test repeat triggers so a helpful reminder does not become a loop.
• 3

  Can users revisit an in-app notification?

  Only if the implementation supports it. A temporary banner, modal, or tooltip may disappear after dismissal or expiration. Store information that users may need later in a notification inbox, activity feed, account screen, or another durable destination.

Create Notifications Around the User's Next Action

A useful in-app notification connects one eligible audience and one meaningful trigger to one clear next action. Define the implementation boundary before writing the copy, test the complete experience rather than the preview alone, and measure whether users complete the intended task. That approach makes the notification easier to evaluate—and less likely to become another interruption inside the app.
