Creating web push

After configuring the web push module and the dynamic content that displays the agreement form, you are ready to create and send a web push. In this process, the main steps are: defining the recipients of the notification, selecting a template, and scheduling the web push notification.


You must be granted a set of user permissions that allow access to Communication module and performing actions with regard to messages.

Creating web push notifications

  1. Go to Communication icon Communication > Web Push > Create new.
  2. Enter the name of the notification (this name is visible only on the list of the web push notifications).

Select recipients

  1. To define recipients, in the Audience section, click Define.

    • To select all customers (with the web push marketing agreement on) you have in your database, select the Everyone tab.
    • To select an existing group of customers, select the Segment tab and select the groups. If you select more than one, the customer must belong to at least one of them
    • To define a new group of customers, select the New audience tab and follow the procedure described here.
    Important: Regardless of the way of selecting the audience, the system limits the audience to those who have agreed to web push marketing.
    Advanced options - explanation

    • Batch delivery - It prevents sending web push notifications to all recipients at once.
      When to use it? When there is a risk that sending all of messages at once will result in excessive traffic on your website or the target audience is so large that the messaging provider might not be able to process all messages at once.
    • Enable control group - It creates a subgroup of the recipients who won’t receive any web push notification variant.
      When to use it? When you send one or several variants of web push (A/B testing). When a customer is assigned to their control group, the information is available in their Profiles card as an event.
    • Include audience changes - Available only for scheduled web push notifications. It recalculates the number of recipients right before sending the notification. By default, the size of the customer segment chosen for the notification is the same as in the moment of sending, even if the number of customers in the chosen segment changed between creating the notification and sending. When to use it? When the size of the segments of customers selected as the audience of the notification can change dynamically.
    • Ignore limits - If you want to make sure that this message is sent to a customer, even it exceeds the global limit of this type of messages for a single customer per day (more information is available here), enable the Ignore limits toggle. You may apply it to system messages such as a transaction confirmation, notifications about order delays, and so on.

  2. Confirm the selection by clicking Apply.

    How to check the number of customers who will receive web push?

    A customer receives a web push notification only if they agreed to receive such notifications (through an agreement form) and they must have an active token. To verify the number of customers who will receive the notification, perform the following steps:

    1. Create a segmentation.
    2. In the first condition, use a receive_webpush_messages attribute set to true.
    3. In the second condition, use a snrs_has_webpush_devices attribute set to true.
    4. Define the dependency between two conditions as AND.
    5. Click Save and check the preview.

Select a template

  1. To select the web push template or create a new one, in the Content section, click Define.
  2. Click Create message.
    Result: You are redirected to the template library.
  3. To create:
    • a message from scratch, click New template.
      Tip: The procedure of creating a web push template from scratch is described here.
    • a message based on an existing template, select a template from the list.
      1. Find the folder the template is saved in.
      2. Click the folder.
      3. Select the template.
      4. If needed, make changes to the template.
      5. If the service approval is disabled for your workspace, click Next.
      6. If the service approval is enabled and you made changes to the template:
        • The system uses the approved version of the template if you proceed.
        • You can send the template for approval once again.
  4. To add more variants of the notification, click the Communication icon icon.
  5. Perform actions described in step 3.
  6. Confirm by clicking Apply.

Schedule the notification

Schedule section
Schedule section
  1. To define when the web push is sent to your customers, in the Schedule section, click Define.
  2. You can choose from two options:
    • To send your notification after clicking the Send button on the upper right corner, use the Immediately option.
    • To plan a message to be sent at a future date, use the Scheduled option. Set the start time and the time zone.
      Synerise performs best with real-time data. This is why you can’t schedule a message for more than 10 days in the future.
      To select the best time of sending the message, take a look at the suggestion from the AI engine that calculates the best time (for all recipients). If time optimization is disabled, click here to learn more how to enable it and use it.

  3. In Time to live, define the time for how long the push service will keep trying to send the notification to the browser. If the push service can’t deliver the notification within that time (for example, due to the user’s device being turned off), the notification will be discarded. The notification is only shown to customers whose browsers are running (also in the background) within this time range.
    If you leave this field empty, it defaults to 7 days.
  4. Select the Silence Hours setting:
    • Without silence hours - The communication can be processed and sent out to the recipients at any time during the day.

    • Include silence hours - With this option, you can set a time of day when the communication can’t be sent:

      1. In the From field, select when the silence hours start.
      2. In the To field, select when the silence hours end.
        The period can’t be longer than 12 hours.
        When a message can’t be sent due to silence hours, a webpush.skipped event is generated.
      • When silence hours are enabled, the Discard messages option is always enabled. This means that messages blocked by silence hours are discarded entirely. The discarded messages are not sent when silence hours end.
      • If the Start time of the schedule is in the silence hours, you can’t apply the settings.
      • If communication is scheduled for sending just before silence hours (for example, silence hours start at 22:00 and sending is scheduled at 21:59:59), the communication may be processed, sent, and logged in the events a short time after the silence hours start.
  5. To save the changes, click Apply.

Define UTM parameters

  1. Optionally, you can add UTM parameters. In the UTM & URL parameters section, click Define.
  2. Fill in the UTM campaign, UTM medium, UTM source, UTM term, and UTM content fields.
  3. Confirm by clicking Apply.


In this part of the process, for testing purposes, you can send the message or one of its variants to the recipients you indicate in this section.

  • You can send the test message only to the users available in the Profiles list and who have the has_web_push_devices set to true.
  • Test messages are not counted towards capping limits.
  1. In the Test section, click Define.
  2. If your message has more than one variant, select the variant of the message which you would like to use for testing.
  3. In the Select the user you want to send the test message to searchbox, search the recipients by name, surname, email address, custom ID, or UUID.
    Result: A dropdown list with search results appears.
  4. On the dropdown list:
    • if you have saved list of recipients in the past, click the Saved lists tab.
    • if you want to define a one-off list of recipients, select the users to include in your list.
  5. Confirm your choice by clicking Add in the searchbox.
  6. Optionally, to save the list of recipients for future use, click Save list.
    Result: A pop-up appears.
    1. In the List name field, enter the name of the list of recipients.
    2. Confirm by clicking Apply.
      Result: The list is available in the Saved lists tab on the dropdown of searchbox when it’s clicked.
  7. To send the message, click Send test.

Adding custom parameters

  • weppush.send
  • weppush.notSent
  • webpush.capping
