How to Set Up Stream Alerts in Streamelements

You’ve just gone live. A new viewer, intrigued by your title, clicks on your stream. The first thing they do? They follow, waiting to see what happens. In this critical moment, a generic, pixelated alert pops up with a robotic voice. The viewer’s excitement fades. That small detail, a default alert, just told them your stream is like everyone else’s.

Now, imagine a different scenario. A custom, beautifully animated alert that matches your brand’s energy explodes onto the screen with a unique sound. The new follower feels an instant rush of excitement. They feel seen, welcomed. They’ve just been given a taste of your brand’s quality, and now they’re here to stay.

This is the power of professional stream alerts. They are not just notifications; they are the heartbeat of your channel’s brand and community.

In this ultimate guide, we will teach you not only how to set up stream alerts for Twitch, YouTube, and Kick, but also how to use them as a powerful tool for growth. We’ll cover the best platforms, the step-by-step setup process, and pro tips that top streamers use to turn viewers into loyal fans. Ready to level up? Let’s begin.

What Are Stream Alerts and Why Are They Your Most Powerful Growth Tool?

At its core, a stream alert is a real-time visual and audio notification that appears on your stream to acknowledge a viewer’s action. But strategically, they are much more than that. Professional alerts are a critical component of your growth strategy, serving four key functions:

1. Instant Viewer Gratification: When someone follows, subscribes, or donates, your custom alert provides an immediate, public thank you. This positive reinforcement creates a dopamine hit for the viewer, making them feel valued and recognized in front of the entire community.
2. Encourages More Support (Monetization): A well-designed, exciting donation or subscriber alert creates a mini-event within your stream. Other viewers see the celebration and are psychologically encouraged to participate as well, creating a powerful feedback loop that can significantly boost your income.
3. Strengthens Your Brand Identity: Are you a high-energy, competitive gamer? A chill, lo-fi artist? A chaotic comedy streamer? Your alerts should reflect that. Custom alerts are a key part of your stream branding, reinforcing your channel’s unique vibe with every notification. A great example is our dynamic Valorant Stream Alerts package, designed for a sharp, competitive feel.
4. Builds Community: Alerts create shared moments. When your signature “Raid Alert” plays, your community knows exactly what’s happening and how to react. These shared experiences and inside jokes are the foundation of a strong, dedicated community.

The Foundation: Choosing the Right Alert Platform

To manage your alerts, you need a browser-based alert management tool. These services host your alert graphics and logic, and you simply add them to your broadcast software (like OBS) via a single “Browser Source”. The two industry leaders are StreamElements and Streamlabs.

• StreamElements (Recommended): An incredibly powerful and flexible platform. It offers deep customization of your alerts and overlays, all stored in the cloud. It’s known for being lightweight and having less impact on your computer’s performance.
• Streamlabs: Another excellent and very popular choice, especially for beginners. It offers an all-in-one solution with its own broadcast software, though its alert customization is slightly less robust than StreamElements.

For this guide, we will focus primarily on StreamElements, as it offers the most professional control. The process for Streamlabs is very similar.

How to Set Up Custom Stream Alerts with StreamElements (Step-by-Step)

This is the most professional and flexible way to manage your new alerts. Follow these steps, and you’ll be running in minutes.

Step 1: Connect Your Streaming Account

First, head over to the StreamElements website and log in with your Twitch, YouTube, or Kick account. Authorize the connection to allow it to read your channel’s events (like new followers and subscribers).

Step 2: Create Your Overlay

In the StreamElements dashboard, go to the “Streaming Tools” section in the left menu and click on “My Overlays”. Click “New Overlay”. You’ll be asked to choose a resolution; select 1080p.

Step 3: Add the AlertBox Widget

You are now in the Overlay Editor. This is your canvas.

1. Click the blue + button at the bottom of the screen.
2. Go to “Alerts”.
3. Click on “AlertBox”.

You will see a default AlertBox appear on your canvas. This single box will handle all your different alert types.

Step 4: Uploading and Configuring Your Custom Alerts

Now for the fun part!

1. With the “AlertBox” layer selected, the settings panel will appear on the left. You will see a list of all the different alert types (Follower, Subscriber, Tip, Raid, etc.).
2. Click the gear icon (⚙️) next to “Follower alert” to open its settings.
3. A new window will pop up. At the top, click on “Change Video”.
4. Click “Upload” in the top right of the next window and drag-and-drop your custom .webm alert file.
5. Once uploaded, select it and click “Submit”.

You have now replaced the default follower alert with your custom animated one!

Step 5: Customizing the Text and Sound

Your custom alert is the visual base, but StreamElements will add the text (like the person’s username) on top of it.

• Layout: Choose how the text appears in relation to your animation (e.g., text below, text over, text to the side).
• Alert Message: Customize the message. The {name} variable will be automatically replaced with the viewer’s username.
• Text Settings: Change the font, size, and color of the on-screen text to match your brand.
• Sound: You can upload a custom sound to play along with your visual alert or remove the sound entirely if your .webm file already has audio.

Repeat this process for your Subscriber, Donation (Tip), and any other alerts you want to customize. For a truly unique and edgy look, check out how our Glitch Twitch Alerts can be customized with different fonts and colors.

Step 6: Adding Your Alerts to OBS Studio or Streamlabs Desktop

Once you have configured all your alerts, click the “Save” button in the top right of the StreamElements editor.

1. At the very top of the editor, find and click the “Copy Overlay URL” button (it looks like a chain link icon).
2. Open your broadcasting software, such as OBS Studio or Streamlabs Desktop.
3. In the “Sources” panel, click the + icon and select “Browser” (or “Browser Source”).
4. Give it a name, like “StreamElements Alerts”.
5. In the properties window, paste the URL you copied into the “URL” field.
6. Set the Width to 1920 and the Height to 1080.
7. Click “OK”.

That’s it! Your custom alerts are now live. You can test them by going back to the StreamElements editor and clicking “Emulate” at the bottom to trigger a test event.

How to Set Up Alerts with Streamlabs

The process for Streamlabs is just as simple, but you configure everything on their website dashboard.

1. Log in to the Streamlabs Dashboard and click on “Alert Box” in the left menu.
2. You’ll see tabs for each alert type (“Follows”, “Subscriptions”, etc.). Click the one you want to edit.
3. Click the image/video icon to open the media gallery. Upload your custom .webm file here.
4. Customize the font, color, and sound settings on the same page.
5. Save your settings at the bottom of the page.
6. At the top of the Alert Box page, copy the “Widget URL” and paste it into a “Browser Source” in OBS or Streamlabs Desktop, just like in the StreamElements method.

Beyond the Setup: Pro Tips for High-Converting Alerts

Setting up your alerts is just the beginning. Using them strategically is what separates amateurs from pros.

• Create Alert Variations: Both platforms allow you to create “Variations” for alerts. Use this to create special, more exciting alerts for larger donations, higher subscription tiers, or gifted subs. This rewards big supporters and encourages others to reach those levels.
• The Perfect Alert Sound: Your alert sound should match your brand and not be overly loud or annoying. A short, distinct, and pleasant sound is far more effective than a long, jarring one.
• Write Compelling On-Screen Text: Don’t just stick with “{name} just subscribed!”. Get creative! Use an inside joke from your community or a catchphrase that is unique to your stream.
• Keep it On-Brand: The number one rule. The style, color, font, and energy of your alerts should be a perfect extension of your brand identity. Consistency builds professionalism and trust.

Frequently Asked Questions (FAQ)

• What file format is best for animated alerts? The industry standard is .webm. It provides the highest quality with perfect transparency (alpha channel) and extremely small file sizes, ensuring your stream doesn’t lag. While .gif files work, their quality is very low and they lack true transparency. .mov files are for video editing and are generally not compatible with browser sources.
• Can I use these alerts on Twitch, YouTube, and Kick? Yes! Platforms like StreamElements and Streamlabs are multi-platform. You simply connect the streaming account you want to use (Twitch, YouTube, or Kick), and the AlertBox will listen for events from that platform.
• Why are my alerts lagging or not appearing instantly? This is almost always caused by using unoptimized files (like large GIFs) or a slow internet connection. Using professionally optimized .webm files, like the ones from StreamSkins, ensures the lowest possible file size and fastest performance.

Conclusion: Your Alerts Are Your Brand’s Heartbeat

Your stream alerts are the most frequent and visible representation of your brand’s personality and professionalism.

Now that you know how to set up stream alerts, it’s time to find the perfect design to represent your brand.
