What is WaSenderHQ?
WaSenderHQ is a bulk WhatsApp message sender extension for Chrome and Firefox. It helps businesses import contacts from CSV or Google Sheets, personalize each message, attach images or supported documents, review the campaign, and send from an active WhatsApp Web session—without setting up an API.
Review more before sending and recover from failures safely
Version 1.3.5 adds attachment previews, a complete pre-send check, focused retries, suppression controls, and clearer campaign tracking.
Pre-send campaign review
Check recipients, invalid numbers, duplicates, suppressions, attachments, delays, and safety warnings before starting.
Retry failed messages
Retry only failed contacts while successful and skipped recipients remain untouched.
Do Not Message list
Exclude suppressed contacts from immediate campaigns, scheduled campaigns, and failed-message retries.
How it works
Send a personalized WhatsApp follow-up in three steps
Start with the contacts and conversations you already manage—without API setup or a complicated campaign builder.
- 01
Install the extension
Add WaSenderHQ to Chrome or Firefox, then open your usual WhatsApp Web session.
- 02
Bring in your contact list
Upload a CSV or use a Google Sheet and match the fields you want to personalize.
- 03
Write, review, and send
Create a helpful message for contacts who expect it, then follow campaign progress in one place.
Use WaSenderHQ only for relevant, expected outreach. Respect recipients' preferences and applicable messaging policies.
