Check message flags what to improve, and OneSignal AI can apply the fixes for you. ![Push editor on the left with a weak draft. The OneSignal AI panel on the right shows a verdict, a findings table with the issue and why it matters for each line, suggested rewrites, and buttons to apply the rewrites, suggest an image, or add an action button.](https://mintcdn.com/onesignal/xvsa7y1pbuvdchy3/images/check-message/check-message-example.png?fit=max\&auto=format\&n=xvsa7y1pbuvdchy3\&q=85\&s=b44aeb7881ad5469808b55645420db32) Check message reviewing a push draft. OneSignal AI shows a verdict, findings, and suggested rewrites next to the editor. > [!NOTE] > > **Check message** is in beta and supports push notifications and push templates only. Support for other channels is coming soon. ## Prerequisites * Access to [OneSignal AI](https://documentation.onesignal.com/docs/en/onesignal-ai.md). AI features must be turned on for your organization. When AI features are off, the **Check message** button does not appear. * Permission to create and edit messages in the app. ## Check a message **1. Open a push draft or template** Create a new push notification or push template, or open an existing one. **2. Click Check message** Click **Check message**, next to **Review and Send**. OneSignal AI opens in a panel on the right and reviews the message, including the title, body, image, buttons, links, and platform settings. ![Push editor action buttons: Review and Send, Check message, and Save](https://mintcdn.com/onesignal/xvsa7y1pbuvdchy3/images/check-message/check-message-button.png?fit=max\&auto=format\&n=xvsa7y1pbuvdchy3\&q=85\&s=605c3ac107fa04a9d9b3d54f5aa8c5cb) The Check message button next to Review and Send, and Save. **3. Review the recommendations** OneSignal AI starts with a verdict on the message. It then lists findings, with the line, the issue, and why it matters, most important first. Lower-priority items are listed after the findings. For copy issues, OneSignal AI suggests rewrites. **4. Apply the fixes you want** Click a suggested action, such as **Apply the rewrites**, or ask OneSignal AI for a specific fix. OneSignal AI updates the editor after you confirm. Some fixes, such as adding an image, need you to make the change yourself. **5. Save and send** Review the changes and click **Save**. OneSignal AI does not save or send the message for you. > [!TIP] > > You can also ask for a review from the chat. Run the `/critique` skill in OneSignal AI to run the same checks on a draft, template, or recent notification. See [OneSignal AI skills](https://documentation.onesignal.com/docs/en/onesignal-ai-skills.md#critique-push-message-review). ## What Check message reviews **Check message** groups its checks into four categories. OneSignal adds and tunes checks over time, so the examples below are not a complete list. ### Delivery Delivery checks catch problems that stop a push from sending or displaying correctly. Fix these before you send. * **No platforms selected.** The push is not set to send to any platform, so no one receives it. * **Payload size.** The title, body, and additional data are over the platform size limit. See [What is the maximum push notification payload size?](https://documentation.onesignal.com/docs/en/push.md#what-is-the-maximum-push-notification-payload-size) * **Invalid links.** A launch URL or link in the message has broken syntax. * **Image not served over HTTPS.** iOS does not display images hosted on HTTP. * **Invalid Liquid syntax.** A [Liquid](https://documentation.onesignal.com/docs/en/using-liquid-syntax.md) expression in the title or body cannot render. ### Copy Copy checks help your title and message read clearly on a lock screen. * Titles that are too long to display in full * Body text that gets cut off before the key information * Vague titles that don't say what the message is about * Grammar errors and hard-to-read sentences ### Brand and audience Brand and audience checks compare the message to your account data. * **On-brand.** When you have a [Brand Kit](https://documentation.onesignal.com/docs/en/brand-kit.md), OneSignal AI checks the title and body against your brand voice. * **Audience relevance.** OneSignal AI checks whether the content fits the [segments](https://documentation.onesignal.com/docs/en/segmentation.md) you are sending to. ### Rich media and actions Rich media and action checks look at what the user sees and taps. * No image on a message that would benefit from one * Missing or generic [action buttons](https://documentation.onesignal.com/docs/en/action-buttons.md), such as "OK" or "View" * No [deep link](https://documentation.onesignal.com/docs/en/deep-linking.md), so a tap opens the app home screen instead of the relevant page ## FAQ ### Do I have to follow every recommendation? No. Recommendations are suggestions. You decide which fixes to apply, and you can send the message without changing anything. ### Can I stop OneSignal AI from showing a recommendation? Yes. Tell OneSignal AI that you don't want to see a specific recommendation again. OneSignal AI stops showing that recommendation to you in that app. Other team members still see it, and so do you in your other apps. ### Does Check message send or save my message? No. OneSignal AI only changes the editor after you confirm, and you click **Save** yourself. OneSignal AI never sends messages. ### How is Check message different from Refine in the AI message composer? They do different jobs. Use [Refine](https://documentation.onesignal.com/docs/en/ai-message-composer.md) to iterate on your wording in the direction you choose, such as friendlier or more concise. Use **Check message** to compare your message to OneSignal best practices and get guidance on what to change to follow them. ### Can I check email or SMS messages? Not yet. **Check message** supports push notifications and push templates today. Support for other channels is coming soon. ## Related pages > [card] [OneSignal AI](https://documentation.onesignal.com/docs/en/onesignal-ai.md) > > Use the assistant built into the dashboard to get answers, analyze performance, and draft content. > [card] [OneSignal AI skills](https://documentation.onesignal.com/docs/en/onesignal-ai-skills.md) > > Run /critique and other guided workflows from the chat. > [card] [Brand Kit](https://documentation.onesignal.com/docs/en/brand-kit.md) > > Set your brand voice so **Check message** can check that your messages sound like you. > [card] [Push notification CTR](https://documentation.onesignal.com/docs/en/notification-ctr.md) > > Troubleshoot and improve click-through rates on your push notifications.
