In-App Messaging: What It Is and How to Do It

In-app messaging is communication that appears while someone is using your app or website. These messages can take the form of banners, tooltips, notifications, and more, and are built directly into the product itself to guide users, highlight updates, or suggest next steps.

However, what makes in-app messaging particularly effective is its timing. Instead of interrupting someone’s day with a poorly timed push notification or easily ignored email, these messages appear precisely when they’re most needed—right in the moment.

The results speak for themselves: one study found that in-app messaging had a 75% open rate—that’s 45 times higher than email and three times higher than push notifications.

A strong customer engagement strategy uses a mix of communication channels, each with its own strengths:

• Emails are great for newsletters, account summaries, and deeper dives, but they can get lost in crowded inboxes and pull users away from your product.
• Push notifications grab attention outside the app, making them useful for urgent alerts. However, if overused, they can feel intrusive and may get turned off completely.
• Chatbots provide on-demand help, answering questions and fixing issues when they arise. But, they usually need users to start the conversation.

In-app messaging works alongside these channels to create a smoother, more enjoyable experience.

For instance, an in-app prompt can introduce a new feature as it becomes relevant to their journey, while a follow-up email provides extra details for those wanting to learn more. This way, you can meet users exactly where they are, keeping them engaged without the app feeling overwhelming.

In-app messaging follows a straightforward principle: deliver the right message to the right person at the right moment. But making that happen requires a thoughtful process powered by user data, behavior triggers, and careful message design.

Track user behavior

The process starts with understanding what users are doing (or not doing).

When someone completes a task, visits a specific page, or reaches a milestone, an in-app message can respond and direct a user in real time.

Inaction can also be a useful signal. A well-placed pop-up can provide a gentle nudge if a user hasn’t explored a feature before.

Choose the right format

Different messages require different types of response. The system selects the best one based on the situation:

• Tooltips to subtly highlight features or updates
• Modals for critical announcements or confirmations
• Banners to keep key updates on the screen
• Progress indicators to celebrate milestones (like completing an onboarding step).

Segment users for personalization

Nobody enjoys generic messages. By grouping users based on behavior, subscription level, industry, or past interactions, in-app messages can feel more relevant and engaging, like help and guidance, rather than interruptions.

Test, learn, and improve

Testing and refining are also equally important. A/B testing different wording, timing, and design helps fine-tune the overall experience. If a user frequently dismisses certain types of messages, the system adapts, making future messages more useful and aligned to what specific users want.

In-app messaging fills gaps that other communication methods can’t always cover. It improves the user experience in ways that impact your most important metrics: engagement, retention, and revenue.

Drives product adoption

New users often abandon apps when they feel lost or overwhelmed. Well-timed in-app messages provide guidance at potential drop-off points, helping users stay on track instead of giving up. This reduces dreaded “day-one churn” and enables users to see your product’s value faster.

Builds deeper product engagement

People tend to stick to the basics of an app or website unless prompted otherwise. In-app messages introduce users to valuable but often overlooked features, helping them unlock more of your product’s potential.

For example, a design tool user might rely on simple functions until an in-app message reveals more advanced features that could improve their workflow.

Creates memorable learning moments

Users don’t always remember everything from an onboarding sequence they completed days (or weeks) ago. In-app messages deliver help when they actually need it and help to reaffirm knowledge.

Provides insight into feature adoption

In-app messages provide businesses with a window into how their product is being used (or ignored).

If a feature stays underused despite in-app promotions, it may need a redesign. On the other hand, if engagement spikes after a message, you know you’ve highlighted something people find genuinely valuable.

Shows you understand your users

When in-app messaging feels personal and well-timed, users see it as helpful instead of purely promotional. Showing users that you understand them and care about their success makes them likely to continue using your app and recommend it to others.

In-app messages come in many forms. Here are some of the most common types and when to use them.

Banners

Banners appear at the top or bottom of the screen without disrupting the user’s workflow. They’re suitable for:

• Announcements (e.g., introducing a new feature)
• Confirmations (e.g., after a successful action)

Since they’re subtle and nonintrusive, banners work best for FYI-style messages that users can acknowledge and then swipe away without stopping what they’re doing.

Interstitial (half or full)

Interstitial messages briefly pause the user journey to highlight more important information.

They work well for:

• Major product updates
• Time-sensitive promotions
• Celebratory moments (e.g., completing a milestone)

Full-screen interstitials, in particular, can create a strong visual impact—perfect for reinforcing aha moments or marking special achievements.

Modals

Modals require users to take action before they can continue using the product. Because they dim and take focus, they’re ideal for:

• Important decisions (e.g., confirming an action)
• Critical information (e.g., policy updates)

As modals interrupt the user flow more than other options, you should use them sparingly to avoid frustration.

Surveys

Surveys collect direct feedback while users are actively engaging with your product. They work best when they’re:

• Kept short and clear (aim for one to three questions)
• Ask simple, easy-to-answer questions (steer clear of open-ended ones if you can)
• Gathering information that is truly needed
• Timed strategically (e.g., after trying a new feature)

Compared to a follow-up email sent days or weeks later, in-app surveys capture more accurate and immediate insights.

Tooltips

Tooltips provide quick, contextual guidance without getting in the way. They help users by:

• Explaining unfamiliar elements
• Drawing attention to features users might have missed

They’re often used in progressive disclosure—a method of gradually introducing product capabilities so users don’t feel overwhelmed.

Onboarding checklists

Onboarding checklists make learning a new (especially complex) product feel manageable by breaking it down into small, actionable chunks. They provide:

• A clear path to getting started
• A sense of progress and achievement
• A little psychological boost (because checking off tasks typically feels good)

By gently guiding users through the main actions, checklists help them feel more confident, often leading to better retention and long-term engagement.

Using in-app messages effectively requires an approach beyond just pushing notifications in front of a user. It’s about delivering value at the right time in the right way.

Set clear goals for each message

Start by asking yourself what specific action (e.g., upgrading, finishing onboarding, trying a new feature) you want your users to take. This clarity helps you craft more focused content that supports real engagement, unlike run-of-the-mill announcements that users commonly ignore.

Consider your timing

Messages should feel helpful and natural, not random or disruptive. Look for contextual moments to engage, such as:

• After a user completes a task
• Upon reaching a milestone
• When a user seems stuck or isn’t progressing

Keep content concise and action-oriented

Most users typically skim text, especially in apps, so keep your messages short and to the point. Stick to one to two sentences highlighting the benefit, followed by a clear call to action (CTA). Your goal is to guide, not overload.

Personalize whenever possible

Personalized messages resonate better and boost engagement. Use a user’s actual name and reference their specific behaviors: “Hi Sarah, we noticed you’ve been using our reporting feature daily,” instead of a more blanket “Dear user, check out our reporting tools.”

Build in response mechanisms

It lets users dismiss messages, ask for more information, or let you know they’ve already completed an action. Listening to your users and creating a feedback loop helps refine your messaging and prevents you from repeating things unnecessarily.

Respect user preferences

Users appreciate having control. Let them choose how often they receive messages or opt out of certain types. When people feel in charge of their experience, they’re less likely to become annoyed or suffer from message fatigue.

Test different approaches

Small changes can have significant effects. Try A/B or multivariate testing of various elements to find what works best. For example, “Try this new feature” may outperform “New feature available” in driving engagement.

Measure the impact (beyond clicks)

While engagement rates matter, the real, objective measure of success often comes down to whether in-app messages lead to:

• Higher product adoption
• Improved user retention
• Increased conversions

Tie your messaging strategy to these core outcomes to understand its true value and impact on long-term growth.

Effective in-app messaging starts with understanding who your users are and what they’re trying to achieve. This is where your data comes in.

Segmenting user data enables you to craft messages that speak directly to each group's priorities—whether that’s power users vs. newcomers or enterprise customers vs. small business owners. The more you can personalize, the more relevant your messages become.

Going beyond basic demographic information also helps you determine how and when to deliver these messages. Look at:

• The device your users are using
• What time of day they engage with your product
• Whether they’re rushing through tasks or taking their time

An analytics platform like Amplitude helps make these insights actionable.

• Use cohort analysis to pinpoint which user segments benefit most from specific messaging types
• Monitor real-time data on feature adoption, session length, and retention to see how your messages are performing
• Use the Behavioral Graph to predict which features will likely be valuable next based on similar users’ journeys
