OneSignal – Web Push Notifications

Description

OneSignal is an easy way to increase user engagement. Use OneSignal to send visitors targeted push notifications so they keep coming back. It takes just a few minutes to install.

As a WordPress VIP Gold Partner, OneSignal has been rigorously tested to handle even the highest volume use cases with reliability and ease of use.

After setup, your visitors opt-in to receive push notifications when you publish a new post. Visitors receive these notifications even after they’ve left your website, thus driving re-engagement.

You can configure notification delivery at preset intervals, create user segments, and customize the opt-in process for visitors.

OneSignal’s free plan allows targeting up to 30,000 subscribers with push notifications. Contact support@onesignal.com if you have any questions. We’d love to hear from you!

We power push notifications for everyone from early stage startups to Fortune 500 Companies, sending over 6 billion notifications per day. It is the most popular push notification plugin on WordPress with 100,000+ installations.

  • Targeting Segments – Send notifications to specific visitors based on language, number of times they’ve visited your blog, or even set up your own user attributes that you can target.

  • Opt-In Customization – Choose when and how to ask your visitors to opt-in to browser notifications. Customize the prompt they first see.

  • Real Time Analytics – See your notifications being delivered in real time, and watch them as they convert into visitors.

  • A/B Testing – Try out different messages to a smaller set of your visitors to figure out which messages are more effective and then send the more effective message to the rest of your visitors!

  • Scheduled Notifications – Schedule notifications to be delivered in the future, based on a user’s time zone, or even based on the same time of day they last visited your website.

I love OneSignal. It is worth the setup time. This application is very reliable, and I love the user interface. Its so simple that I can only use the word "perfect" to describe it. I do have email subscribers, but OneSignal grows faster and uses a fraction of the bandwidth. Using OneSignal means you will never anger the SPAM gods and you can just get on with creating the most awesome website on the www.

I was having trouble to start using it, then I found the youtube video, from OneSignal channel, so it became easy. I just followed step by step and now it's working. Thanks!

I like this solution a lot, because it simply does what it should. The free version is perfect for small projects. I have to findout where to find the amount of push receiptions ... saw in the account on the OneSignal Website... I'll find ut. Everything works just fine. Thanks a lot for your moods and skills <3

Everything is fine but this plugin indexes its files on Google. And this will lead to drop of rankings. I researched on Google and couldn't find any solution, so I am deleting this plugin.

1.16.10

Updated plugin description and added FAQ section.

1.16.9

Reverting the UI changes for HTTP switch.

1.16.8

This release makes HTTP switch match the dashboard (renamed to “My site is not fully HTTPS”) and removes deprecation warnings for php 7.2.

1.16.7

This release updates the service worker to use a 50% smaller service worker-only file.

1.16.6

This release the issue where even after saving the form, the error about not completing the required fields would appear because the settings for the new page view were loaded before the previous page’s settings were saved. Also a broken doc link was fixed.

1.16.5

This release changes the notification send rate limit from at most one every 10 seconds to at most one every 1 second.

1.16.4

This release removes begining and ending whitespaces from textboxes when saving. This can fix common errors like pasting the App ID, REST API Key, or subdomain (also called label) with an ending whitespace which normally causes errors.

1.16.3

This release greatly simplifies the setup guide to follow our documentation instead of an inline guide.

  • Update AMP helper files to be centralized instead of hardcoded inlined JavaScript

1.16.2

This release updates the amp-helper-frame.html and amp-permission-dialog.html files used for amp-web-push due to permission changes in Chrome 62.

  • Update readme to show tested up to 4.9 Release Candidate 2

1.16.1

This release adds an option to disable the “Successfully sent a notification to X recipients” message, and also includes files for AMP web push (to be used with another AMP plugin) in case you decide to add AMP web push for your site.

  • Add option “Show status message after sending notifications”
  • Include amp-helper-frame.html and amp-permission-dialog.html for use with AMP web push

1.16.0

This release adds a helpful message describing the notification’s recipient count after sending a notification. After publishing a post, for example, the info box may say “Successfully sent a notification to 100 recipients.”.

  • Lowered priority of wp_head hook from 5 to 10.

1.15.1

This release fixes a bug with the 1.15.0 release that checks the “Dismiss notifications automatically after ~20 seconds” field. The wrong field was being checked and caused a warning to appear.

1.15.0

This release adds a setting for hiding notifications on Mac OS X platforms.

  • “Dismiss notifications automatically after ~20 seconds” has been replaced with “Hide notifications after a few seconds” with a couple of
    choices “Yes”, “No”, “Yes on Mac OS X. No on other platforms”. Previously, notifications would be persisted on all platforms except Mac OS X.

1.14.4

This release restores 4 missing image files in the Setup guide included in our WordPress plugin (Chrome & Firefox Push step 7, OneSignal Keys step 2).

No code changes were made in this patch.

1.14.3

  • Use larger sized icons for the featured image

    Notification small icons and large images previously used the uploaded image closest to size 80×80. For a large uploaded image with no
    resized variants, there would be no issues. But for uploaded images resized to different sizes by WordPress, this caused the smallest image
    size to be selected and look blurry. Notification small icons now use the closest available image to 192×192 for a sharper image, whereas
    large images use the closest available image to 640×480.

1.14.2

  • Update Setup tab’s images and text

    Clarify some steps that are typically confusing to new users setting up the plugin, like how to get the value in the Subdomain textbox.

1.14.1

  • Remove .htaccess file

    Apache httpd.conf configurations that don’t allow custom .htaccess options will error out with a 500 if we place this file there.

1.14.0

  • Update semantic versioning; update minor version for new backwards-compatible functionality
  • Hide Google Project Number from configuration (using one is unnecessary since we provide a default Project Number)
  • Add option “Use the post’s featured image for Chrome’s large notification image” (see: https://goo.gl/uSDr5p)
  • Lower notification rate limit from 55 seconds to 10 seconds. Countdown shows time remaining (e.g. “Please try again in 6 seconds”)

1.13.9

  • Check in missing image to SVN: admin Configuration page HTTP Permission Request modal
  • Remove obsolete admin option “Show the OneSignal logo on the prompt”
  • Remove unused Bootstrap CSS/JS assets
  • Fix Prompt options custom language text not outputted for HTTPS sites (https://goo.gl/5Hi4HA)

1.13.8

  • Config page changes

1.13.7

  • Add rate limiting to prevent notifications from being sent too quickly; one notification can be sent every 55 seconds
  • Remove Preview Popup button; users can still follow the screenshot in the section header to match their customized
    values with the window their users will see

  • Add a hidden page comment if users disable OneSignal initialization for easier debugging
