Overview

AppBoost Web Push Notifications is a channel for marketing managers and e-commerce teams to send clickable browser notifications to visitors who have opted in, without needing their contact details. It supports immediate, scheduled and recurring sends, segment targeting, event-based automation and a REST API, and installs through the Web SDK or a no-code store integration.

Key facts

No-code install
Shopify, Salla and Zid through the Shrinkit app
SDK requirement
Web SDK plus firebase-messaging-sw.js in the site root

The problem

Most site visitors leave without leaving a trace

Visitors who browse and leave give you no email or phone number to follow up with. Web push lets them opt in with one click, so you can re-engage them later without collecting personal contact details.

Capabilities

What Web Push Notifications includes

  • Immediate, scheduled, recurrent

    Send now, at a set time, or on a repeating schedule that runs hourly, daily, weekly or monthly, and target different time zones.

  • Segment targeting

    Send to all subscribers or to a segment identified by the user IDs from your app, so messages reach the right people.

  • Event-based campaigns

    Trigger automated, behavior-based web push through the Appgain Automator, such as reminders after a visitor shows interest.

  • Links and destinations

    Attach a URL, a Smart Link or a Micro Page to open when the notification is clicked, or send text only.

  • Templates and emoji

    Reuse saved push message templates to save time on every campaign, and add emoji to make notifications more noticeable.

  • Bulk and one-to-one sends

    Run a campaign to a broad audience or send a single notification to one person, with statistics for both.

  • Detailed analytics

    Review sent and failed counts per platform, subscriber acquisition channel, opt-in versus opt-out, and subscriber locations.

  • REST API and no-code installs

    Automate campaigns and one-to-one messages through the REST API. On Shopify, Salla and Zid, web push installs when you add the Shrinkit app.

How it works

How Web Push Notifications works

  1. 1

    Install web push

    On Shopify, Salla or Zid, add the Shrinkit app. On other sites, add the Web SDK and place firebase-messaging-sw.js in your website root directory.

  2. 2

    Collect subscribers

    Visitors opt in through the browser prompt. You can also gather subscribers with Short Links or Micro Pages if you have no website.

  3. 3

    Create a campaign

    Open Store, choose New Campaign, select Web Push and enter the campaign name, a message of 160 characters or fewer, and the destination URL.

  4. 4

    Schedule and send

    Choose immediate, scheduled or recurrent delivery and submit. Then follow subscriber growth and campaign success ratios in the dashboard.

Frequently asked questions

Web Push Notifications FAQ

Which devices and browsers receive web push?
Web push works on desktop and Android. It is not supported on iPhone or iPad because Safari on iOS lacks the Web Push API, although notifications are supported on macOS through Safari. Plan a fallback channel, such as SMS or email, for iOS visitors.
How do I add web push to my website?
Add the Appgain Web SDK script and initialize it with your project ID and API key, then place firebase-messaging-sw.js in your site root, which push requires. On Shopify, Salla and Zid, installing the Shrinkit app adds web push automatically.
Can I collect subscribers without a website?
Yes. The docs state you can gather web push subscribers through the default integration with Short Links, and Micro Pages are listed as a subscriber acquisition channel. This lets you build an audience before you have a site of your own.
How long can a web push message be?
The campaign form limits the message to 160 characters or fewer. You also add a campaign name and the URL that opens when the user clicks. Keep the text short and specific so the value is clear from the notification alone.
Can I send web push automatically?
Yes. You can schedule sends as immediate, later or recurrent (hourly, daily, weekly, monthly), and run event-based campaigns through the Appgain Automator. The REST API is available for automated campaigns and one-to-one notifications from your own system.
How does web push fit with other AppBoost channels?
Web push shares the Omni-channels area with app push, SMS, email and WhatsApp. Marketing automation can send web push alongside the other channels, and Short Links and Micro Pages can serve as destinations or subscriber sources.
