14:32 ✓✓What WASENDERHQ Actually Delivers
100% verified extension capabilities directly from our Manifest V3 source code — built with group member extraction, account safety meters, privacy masks, and smart delay jitter.
Spintax Phrase Variations
Rotate greetings and phrasing to avoid repetitive text patterns
Use spintax notation like {Hi|Hello|Good day} to alternate text variations automatically across recipients, preventing identical message pattern flags.
Group Member Extractor
Extract participant numbers directly from WhatsApp Web groups
Extract raw phone numbers and contact names from any WhatsApp Web group in seconds with one click, giving you targeted prospect lists instantly.
Privacy Mask Overlay
Blur contacts and messages during screen shares or video calls
Built-in privacy toggle that automatically blurs contact names, profile photos, and message content on WhatsApp Web to prevent accidental data leaks during recordings or screen shares.
Account Safety Monitor
Continuous monitoring of sending velocity and delay boundaries
Monitors sending speed, volume, delay boundaries, and template text variations to keep your WhatsApp outreach pace organic and within safe limits.
Delay boundaries & spintax variations active.
Smart Account Warm-Up
Progressively scales daily message caps to build account trust
Protects new or fresh WhatsApp accounts by automatically scaling allowed daily outbound dispatches in calculated increments, establishing organic sender reputation.
Phone Number Engine
Normalizes, validates, and deduplicates international numbers
Automatically formats country codes, removes invalid symbols, strips duplicate phone entries, and verifies correct international number syntax before sending.
Pause & Resume Queue Engine
Freeze and continue sending; survives browser restarts
Pause sending mid-way and resume whenever you want. Session state persists in `chrome.storage.local`, so closing the browser tab or popup will never lose your queue state.
Smart Delays with Jitter
Adjustable randomized wait boundaries to mimic typing profile
Configurable wait intervals (e.g. 4s - 9s) with random millisecond jitter between individual contacts to emulate realistic human typing speeds.
Schedule Send Engine
Background scheduling powered by Manifest V3 service workers
Schedule messages to launch at a future date and time. Uses Chrome Manifest V3 `chrome.alarms` service worker API to trigger sending queues reliably.
Triggers: Tomorrow at 10:00 AM
Message Template Manager
Save up to 5 custom templates with single-click loading
Store your top message drafts, follow-ups, and customer reminder templates in local storage and load them with one click into your message composer.
Live Stats & Activity Log Export
Animated counters for opened, sent, remaining, and skipped contacts
