Check message reviewing a push draft. OneSignal AI shows a verdict, findings, and suggested rewrites next to the editor.

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. 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

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.
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.

​
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?
  • 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 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, OneSignal AI checks the title and body against your brand voice.
  • Audience relevance. OneSignal AI checks whether the content fits the segments 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, such as “OK” or “View”
  • No deep link, 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 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.
