How we compared
We read each extension's Chrome Web Store listing on the date above and recorded only what the listing states. Wassender's column reflects the published version shown in the table. Nothing here is a paid placement.
Where each one fits
Wassender: businesses that send personal messages built from spreadsheet data (orders, appointments, invoices), want conditional wording, auto-replies and per-recipient reports, and need a full Arabic interface.
WASender: the most widely installed option, with AI replies and CRM-style features according to its listing.
WAMessager: a permanent daily free allowance suits very small, steady sending.
Wa Bulk Sender: a minimal free tool if you only need plain messages to a list.
What none of them change
All of these extensions send through your own WhatsApp Web session. WhatsApp can restrict any number that sends unwanted messages; safe pacing helps, but consent matters most. For very high volume or automated transactional messaging, the official WhatsApp Business API is the right tool.
How to choose
- Does the free allowance fit your list size? A daily allowance and a short full-featured trial suit different needs.
- Do you need more than a name — order numbers, dates, amounts, or text that changes by condition?
- Do you need auto-replies, scheduling and a per-recipient report you can export?
- Do you message customers in Arabic or another right-to-left language?
- Read recent reviews and check the last-updated date: WhatsApp Web changes often.
Frequently asked questions
What is the best free WhatsApp bulk sender Chrome extension?
It depends on volume. WAMessager states 50 free messages per day. Wassender gives every new account 1 hour of Unlimited with all campaign features from the first campaign. Wa Bulk Sender is free but basic.
Are WhatsApp bulk sender extensions safe?
They automate WhatsApp Web in your browser; check each one's privacy policy and permissions. Wassender stores spreadsheets and history in your browser and does not read your conversations. Your number's safety depends mostly on messaging people who expect you.
Is Wassender the same as WASender?
No. Wassender is made by Genoun. WASender is a separate extension by another developer with a similar name.
Do these extensions use the WhatsApp Business API?
No. They work on top of WhatsApp Web with your own account. The Business API is a separate, paid, official service.
