WA Auto Sender Studio

Send WhatsApp messages to your own contact lists from WhatsApp Web, with templates, media and per-plan daily limits.

WA Auto Sender Studio sends WhatsApp messages to multiple contacts directly through WhatsApp Web. You enter the recipients and write the message yourself - nothing is sent until you review the list and press Start. FEATURES - Send text messages to multiple numbers you provide - Send image messages with an optional caption (Pro / Business) - Import contacts from CSV (Pro / Business) - Custom parameter messages (Pro / Business): import a CSV parameter table and every column you add - name, company, appointment date, order reference - becomes a per-recipient variable. Write {欄名} or {人名} in the message and each recipient receives their own value at send time, so one template still reads as a message written for that person. Tables are stored locally and can be reused for the next campaign without re-importing. - Contact and group management (Pro / Business) - Message templates with {欄名} variables (Pro / Business) - Random send interval, plus delayed send - Pause, resume and stop a batch at any time - Sending continues while the popup is closed - Delivery report with export to CSV - Daily quota tracking with plan-based limits PLANS - Free: 20 messages/day, text only, 1 device, no CSV import or templates - Pro: unlimited messages/day, all features (including custom parameter messages), 1 device - Business: unlimited messages/day, all features (including custom parameter messages), 5 devices HOW TO USE 1. Open https://web.whatsapp.com and sign in 2. Click the WA Auto Sender Studio icon in the toolbar 3. Paste phone numbers (or import a CSV on Pro / Business) 4. Write your message (message templates are Pro / Business) 5. Review the recipient count, then press Start PRIVACY - Your phone numbers, message text and media files stay in your browser. They are never sent to us. - The only data that leaves your device is: your license key and an anonymous install ID (to activate and validate your license), and a daily count of messages sent (to enforce your plan quota). - If you buy a plan, our payment provider (Stripe) collects your email address so we can deliver your license key. - We do not sell or share your data with third parties. Full policy: https://wass.appza.app/privacy PERMISSIONS EXPLAINED The extension asks for these permissions, and each is used only for the stated purpose: - storage - saves your number list, message draft, send progress and license state locally - scripting - runs the send routine inside the WhatsApp Web tab you already have open - activeTab - accesses the WhatsApp Web tab only when you start a send - tabs - finds the open WhatsApp Web tab and opens the manager window - alarms - keeps the send loop running while a batch is in progress - clipboardWrite - places your image on the clipboard so it can be pasted into the WhatsApp composer - debugger - generates trusted keyboard input (Ctrl+V and Enter) in the WhatsApp Web composer. WhatsApp Web ignores synthetic DOM events, so image-with-caption and Enter-to-send do not work without it. Only the CDP Input domain is used; it never reads page content, network traffic, cookies or credentials, and it attaches only to your active WhatsApp Web tab while you press Start.
