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.

You can now add labels during message creation making it easier to organize messages from the start. This update also expands label support to include In-App Messages (IAMs) and SMS messages, giving you more consistency and control across all message types.

We've updated our CSV importer so you can include emails, phone numbers, and data tags in a single file, eliminating the need to split and reformat your data.

What’s new:

• 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.

To try it out, go to the Import page in your OneSignal dashboard. The importer will guide you through mapping, validation, and reviewing your results.

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.

These updates are especially useful for apps with real-time transactional updates—like sports scores, food delivery, or ride sharing—giving you more precision and speed in how your Live Activities are delivered and displayed.

You can start using these parameters immediately in your API requests. If you’re not using the OneSignal SDK, it's recommend you manage duplicates with an idempotency_key.

You can now securely and automatically export your OneSignal data directly to Databricks. This new integration allows teams to sync key message event data, including sent, received, clicked (and more) into their Databricks Lakehouse environment. By centralizing this data alongside the rest of your customer information, you can power advanced reporting, build custom dashboards, and generate deeper insights into the impact of your messaging.

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.

When navigating to the dashboard, select “New Message” > “New In-App” or “New Email,” your available templates will be displayed with visual previews for faster selection. This update eliminates guesswork, speeds up the workflow, and ensures teams can quickly find and apply the right template to create engaging, on-brand messaging in less time.

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.

Documentation for this new feature can be found here.

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.

We highly recommend making use of our Test & Preview functionality so you can always see the most up-to-date message designs, with personalization, on your own device.

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.

PII masking is available exclusively for Enterprise customers and for Professional or Growth plan customers who have opted into the Security and Legal package. To enable this feature, contact OneSignal Support or your dedicated Account Manager.
