Changelog

• We’ve made it easier to clean up outdated segments.
• Previously, you couldn’t delete a segment if it was tied to an In-App Message (IAM) or Journey, even if that campaign was paused or archived. Now, when you try to delete a segment, you’ll see a modal listing all IAMs and Journeys that are preventing deletion.
• This helps you quickly locate and update the associated campaigns, so you can keep your workspace clean and organized without having to hunt through every Journey or IAM.

• You can now create user segments based on how they interacted with previous messages across push, email, SMS and in-app.
• This update adds a new Message Event filter that allows you to segment users based on events like email opens, push clicks, SMS failures, and more - without relying on tags or external tools.
• Available on all paid plans.
• See Segmentation for more details.

• We’ve updated our docs!
• New AI features and easier readability.
• Updated API reference and openapi spec.
• New Tutorials page with common use cases and step-by-step details to get you setup quickly!

• Customers can now see In-App Message impressions, clicks, and click-through rates directly in the Engagement Trends chart. This update gives marketers a unified view of how users are interacting with all message types over time—including In-App—making it easier to spot trends, report on performance, and optimize messaging across channels.
• With this update, In-App engagement data is now included alongside push, email, and SMS across all views in the Engagement Trends chart. Stats are grouped by day and support up to two years of data (depending on plan). This data is exportable via CSV just like other channels, and can be filtered to look at specific date ranges or message types.
• This feature is available to all customers.

• Customers can now track engagement on every individual link within their emails. This update gives customers a much clearer view into what content or messaging is working so they can improve email performance over time.
• Previously, when customers included multiple links within an email, they could only view total click counts across all links. Now, they can see which specific links get the most engagement and how links perform inside journeys. This helps them refine content and messaging strategies.
• Multi-link tracking is automatically applied to most emails created in the Drag & Drop or HTML editor. Link-level performance metrics will also be available for emails sent using a template and emails in a Journey.
• This feature is available to all customers with access to email.

• OneSignal customers can quickly assess how individual templates are performing across all messages, without needing to download and stitch together separate reports.
• When users click into a template, they now land on a detailed analytics view showing Delivered, Unique Opens, Unique Clicks, and Unsubscribes. They can track performance over time, filter by platform, explore delivery breakdowns like Failed or Capped, and review a list of messages that used the template.
• Template analytics is especially useful for:
  • Marketers who test and iterate on message content
  • Developers who need visibility into transactional message delivery
  • High-volume senders seeking scalable insights
• Transactional visibility is a key differentiator that sets us apart from Firebase and other open source solutions. Customers can now answer questions like “How many Account Confirmation emails did I send last week?” or “What was the click-through rate on my Password Reset messages?”
• Important note: For templates created before April 17, 2025, enhanced metrics are only available for messages sent after that date. Customers can use the “Show historical data” toggle at the top of the page to see earlier performance data.
• The feature is live and available by default. Reporting history varies by plan:
  • Free: 30 days
  • Growth: 90 days
  • Professional: 1 year
  • Enterprise: 2 years

• You can now create new users directly from the Users tab in your OneSignal dashboard using a simple form. This update makes it easy to manually add a user with an email address, phone number, or both without needing an SDK, API call or CSV upload.
• This is especially helpful for quickly testing campaigns or adding users who aren’t yet in your system.

• Customers can now track SMS link performance directly in OneSignal without needing third-party tools like Bit.ly or custom UTM parameters. This feature gives our customers a more streamlined, built-in way to measure engagement and optimize messages faster, removing friction and helping drive better results from their SMS efforts.
• When composing an SMS message, customers simply click “Insert Trackable Link” and enter the full URL they want to send users to. OneSignal automatically shortens the link using the 1sgnl.co domain so it fits within SMS character limits and can be tracked.
• All SMS users will have access to trackable links as part of their existing plan.

• Now you can add labels to your messages to help you organize and manage them.
• See Labels for more details.

• You can now view and optimize template performance from a centralized reporting view. Click into any message template to view detailed performance data across every message a template is used in.

• Real-time validation: Get instant feedback on formatting errors before upload.
• Smart column mapping: Easily align your CSV headers with OneSignal fields.
• Email suppression support: Add or manage your suppression list directly in the file.
• Upload history: View the status of your past imports for up to 30 days.
• Helpful templates: Start quickly with a pre-built CSV example.

• You can now add more control, reliability, and speed to your Live Activities with three new parameters in the OneSignal API:
  • ios_relevance_score: Helps determine which Live Activity displays most prominently on iOS.
  • include_aliases: Allows you to target individual users directly rather than relying on segment-based delivery.
  • idempotency_key: Prevents the creation of duplicate Live Activities when retrying start requests if not using the OneSignal SDK.

• OneSignal customers can now effortlessly sync their app’s message event data—including push, email, in-app, and SMS—directly to Databricks. This integration enables secure, automatic data transfer, allowing teams to unify their OneSignal messaging data with broader funnel insights. By centralizing this data in Databricks, customers can unlock deeper analytics, measure the impact of their messaging, and make more data-driven decisions with ease.

• You can now see SMS opt-out status by sender, giving you better visibility and control when managing marketing and transactional messages.
• With this update, you can:
  • View subscription status by individual sender for any phone number
  • Continue sending transactional messages (like OTPs or alerts) even if a user has opted out of marketing
  • Maintain deliverability and avoid carrier filtering by respecting opt-out preferences
• This is especially useful if you manage separate senders for promotional and transactional use cases.
• To access this feature, go to Consent Management > Advanced Opt-out Settings and turn off the setting that globally unsubscribes a user when they reply with an opt-out keyword.
• Note: This option is only available to customers using advanced opt-out settings for SMS.

• Quickly identify and select your email and in-app message templates with the new updated card view.
• Instead of relying on template names alone, you can now see clear visual previews, making it easier to choose the right template at a glance.

• Keep your users in sync across HubSpot and OneSignal! With this new workflow action, you can now create users in OneSignal whenever a HubSpot workflow trigger fires. This enables you to queue up personalization details (such as data tags) and plan engagement strategies before a user even interacts with your mobile platform. Additionally, you can trigger an SMS or email via HubSpot while simultaneously creating a user in OneSignal—ensuring seamless and immediate engagement.
• HubSpot Documentation

• As operating systems update, they often introduce new changes in their push designs.
• We’ve updated our previews so they match latest and greatest push notification designs across iOS (18), Android (15), Windows (11), macOS (Sequoia). This ensures you see what your users will see when testing in OneSignal.

• Protect user privacy and reduce compliance risks by masking personally identifiable information (PII) such as emails and phone numbers. With PII masking, your team can work securely while still analyzing campaign performance and sharing insights across teams.
• OneSignal automatically masks phone numbers and emails in the dashboard and any data exported directly from the platform. However, PII masking does not currently apply to data accessed via API requests, external IDs, or data tags.

• Sends the user a one-time verification code to ensure the customer owns the phone #
• Confirms the phone number entered by a user at onboarding is valid

• OneSignal customers can now effortlessly sync their app’s message event data—including push, email, in-app, and SMS—directly to BigQuery. This integration enables secure, automatic data transfer, allowing teams to unify their OneSignal messaging data with broader funnel insights. By centralizing this data in BigQuery, customers can unlock deeper analytics, measure the impact of their messaging, and make more data-driven decisions with ease.

• The counts of subscribed counts for each channel have moved from the dashboard to the Subscriptions page in OneSignal. Now you will see the number of Subscribed subscriptions for each channel at the top of the Subscriptions page under Audience to get an overview of audience reach per channel in the context of your subscriptions.
• If you still wish to view this information on the Dashboard, you can filter your Subscriptions trends chart by channel.

• We’ve made a couple of improvements to our SMS keywords.
  • Segment by subscription status when sending a keyword to encourage converting your customers who are not yet subscribed into opting in to your SMS marketing messages
  • Setup an auto-responder for unrecognized keywords

Clear empty states show when there’s no data in either tab, and updated messaging ensures you know the logs display a sample of your data.

SMS Keywords

• Now you can export the data from your Subscription Trends report as a CSV. If you apply filters to the report, OneSignal will export based on the filters you’ve applied so that you can fine-tune the data that you use to evaluate your messaging audience.

• Saved Rows are reusable content blocks that help streamline email creation and management. Many companies, especially those that have a lot of templates, prefer to use saved rows in their emails for consistency and to save time. Saved Rows are easily attached to new emails so you don’t have to create the same information from scratch each time. And when things change, you just have to update the saved row, and your updates will automatically sync across all campaigns that have that saved row attached.
• Common use cases include:
  • headers (logo, slogan)
  • footers (company details, social media links, mailing addresses)
  • disclaimers
  • other elements that are used across multiple campaigns
• You can now save Email Drag-and-Drop rows to use across many Campaigns or Templates. These re-suable Saved Rows make it easy to sync updates across many emails at once. Click on the Rows tab of a Drag-and-Drop email, to view your Saved Rows. To save your first row, click the save icon in the edit, in the top right corner of the row.
• We recommend you set up all of your templates to use saved rows for your header and footer so that you need to update the branding or content; you only have to make those edits once.

• Now, Journeys do not require External IDs to be set on subscriptions. Instead, Journeys will target your entire user base within OneSignal, including anonymous users. We recommend still configuring External IDs to identify individual users who have subscribed to multiple channels.

• We now make it easier to manage your Consent Keywords within Onesignal. Reach out to support if you’d like to update the default consent keywords and replies.

• Now you can use Message Personalization within the reply-tofield on an email. This allows you to direct message replies to the right inbox and can be helpful if you are sending from different brands or across different countries.

• Obtain a list of subscriptions that have faced errors - failures or unsubscribes, for a specific push notification in the push report page.

• Customers can now select and send message events from OneSignal to sync back to their Twilio Segment account, making the Segment integration bidirectional.

• Get a list of subscriptions that successfully or failed to receive a Live Activity on a Live Activity report page, which is accessible through the Delivery - Sent Index. This list can be exported as well.

• In the report page of an in-app message, you can now see which mobile subscriptions viewed (impression) or clicked on an in-app message. Audience activity is available for 30 days from the time the message is displayed

• On May 15, 2024, Google’s FCM service will start to expire stale push tokens for devices that have been inactive for more than 270 days. You may see a spike in Android unsubscribes when sending notifications due to this change. Don’t panic! These are devices that have not been online in over 270 days and are part of Google’s Best practices for FCM registration token management. If the device does come back online and opens your app, OneSignal will automatically resubscribe them to push if they were previously subscribed already.
• See FCM Expired Token FAQ for more details.

• Push notifications can now be capped at a rate of x notifications per any time frame (less than 1 week). Navigate to Settings > Messaging > Push Frequency Capping > Custom (in the time dropdown) to view these settings.
• Read Frequency Capping Documentation for more details.

• Android’s Live Notifications deliver live, dynamic content in notifications to enhance user engagement and app interactivity. This is a feature similar to iOS’s Live Activities feature (introduced with iOS 16), but uses its own set of tools and APIs that enable similar functionalities.

Apps targeting Android 13 must explicitly prompt for permission at a time of their choosing, or the system will display the permission prompt automatically on first launch—often resulting in lower opt-in rates.
• See Android 13 Push Notification Developer Update Guide or our Prompt for Push Permissions guide for details.
