1-Click Opt-In
Web Push: Re-Engage Website Visitors Without Asking for Emails or Phone Numbers
A high-converting soft-ask banner followed by native browser permission. Rich push notifications with thumbnails and action buttons — even when the browser tab is closed.
Zero Forms
No Contact Info Submitted — Still an Active Channel
Forms asking for names and phone numbers create massive drop-off. Web push operates securely via anonymous browser tokens.
Triggers
Price Drops, Abandoned Carts, Back-in-Stock Alerts
Contextual behavioral triggers and transactional updates instead of annoying daily blasts to all subscribers.
EXCLUSIVE CAPABILITY
Two-Step Soft-Ask Before Native System Popups
Throwing a native browser prompt on first load triggers immediate, permanent blocks. Explain the value first within your site's native UI.
Browser Support
Chrome, Firefox, Edge, and Safari — Including iOS 16.4+
HTTPS required. iOS requires Add to Home Screen (PWA) — this is an Apple platform requirement, not a volbor limitation.
EXCLUSIVE CAPABILITY
In-Notification Action Buttons Without Opening Blind Tabs
Buy now, save for later, or open product. Every action click feeds into your analytics dashboard.
E-Commerce
Two Action Buttons
Direct checkout or save for later.
Content
Open Guide
Headline up to 40 characters + rich preview banner.
Transactional
Shipping Updates
Pure delivery status without promotional noise.
Smart Timing
Prompt After 40 Seconds or 50% Scroll — Never on First Paint
Show the prompt only after visitors see value, without interrupting hero banners.
40 Seconds on Site
Or any custom time threshold you define.
50% Page Scroll
Displays the banner only after they read your offer.
2–3 Page Views
Target engaged catalog browsers, filtering out instant bounces.
After Add-to-Cart
High-intent context: “We'll alert you if stock runs low”.
Anti-Fatigue
Frequency Capping and Quiet Hours
Cap delivery at 2–3 pushes per week. Overnight delivery is blocked unless explicitly marked as a transactional alert.
Frequency Capping
Global limits enforced across all active campaigns per subscriber token.
Quiet Hours
Based on the subscriber's local device time zone, not your marketing office.
Message TTL
Expired flash sale notifications won't pop up 24 hours later.
Frictionless Unsubscribe
Standard browser padlock controls plus in-app preference center management.
EXCLUSIVE CAPABILITY
Offline Push Queue Syncs the Moment Screens Wake Up
When a laptop lid is closed, the message doesn't disappear. It waits in the TTL queue and delivers upon wake-up.

FAQ
Frequently Asked Questions About Web Push
Does web push work on iPhones?
Yes, starting with iOS 16.4, provided the user adds your site to their Home Screen (as a PWA). Standard Safari browser tabs on iOS do not support native web push — this is Apple's platform policy.
Is web push GDPR compliant?
Yes. Subscriptions rely on anonymous browser tokens without requiring email or PII. Privacy policies and native browser unsubscribe options are mandatory. Web push opt-in does not replace marketing consent for other channels.
Does the service worker slow down site performance?
No. The worker script executes asynchronously on background threads and should not be bundled with heavy chat widgets.
What happens if a user's computer is turned off?
The notification remains in queue for the duration of its Time-To-Live (TTL). If the device turns on before TTL expires, the push delivers. If it expires, it is safely dropped to avoid showing stale offers.
Can web push be paired with messengers?
Yes. If a web push does not convert, volbor can automatically cascade follow-ups to WhatsApp or Telegram if the customer's contact record exists.
