  description

  WhatsBlast is a powerful Chrome extension designed to enhance your WhatsApp Web experience by making communication faster, more efficient, and organized.
  
  Whether you're reaching out to clients, managing conversations, or handling business outreach, WhatsBlast helps you streamline your workflow without leaving your browser.
  
  Key Features:
  
  - Send messages quickly without saving contacts
  - Simplify bulk or repeated messaging workflows
  - Organize and manage conversations efficiently
  - Save time with a clean, easy-to-use interface
  - Works seamlessly with WhatsApp Web
  
  Perfect for business owners, marketers, recruiters, and support teams who rely on WhatsApp for daily communication.

  WhatsBlast turns WhatsApp Web into a real outreach and lead-management tool.
  
  Personalise every message with {name}, send to a CSV or pasted contact list, and let the extension handle the pacing in the background. A built-in CRM panel sits next to every chat so you can tag contacts, leave notes, and set follow-up reminders without leaving WhatsApp Web.
  
  WHAT YOU CAN DO
  
  → Bulk-send personalised messages
  Upload a CSV, paste a list of numbers, or pull leads from a Google Sheet. Use {name} to personalise per recipient. Attach images, videos, or PDFs. Pause, resume, or stop anytime.
  
  → Pull leads straight from Google Sheets
  Wire your Facebook Lead Ads (or any form) into a Google Sheet, paste the share link, and Leadgrabr fetches only the new leads since you last sent — automatic deduplication, no spreadsheet juggling.
  
  → Tag, comment, and remind on every chat
  A side panel inside WhatsApp Web with tags (using WhatsApp Business labels when available), free-text comments, and reminders that fire as desktop notifications at the time you set.
  
  → Bulk-tag dozens of chats at once
  Search, multi-select, apply — done in one click instead of opening every chat individually.
  
  → Smart pacing built in
  Three speed presets (Safe / Normal / Fast), randomised delays between sends, periodic longer pauses, and a 3-day warm-up schedule for fresh installs. An anti-spam guard warns before you send identical text to a large list.
