About WhatsBlast — WhatsApp Bulk Sender + CRM | Leadgrabr
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.
