About Wassender

What is Wassender?

A Chrome extension that adds a bulk messaging and auto-reply panel to WhatsApp Web. It sends personalized messages from Excel or CSV one at a time from your own WhatsApp account.

Who makes it?

Genoun. Wassender is independent and not affiliated with WhatsApp or Meta.

Which browsers and systems are supported?

Desktop Google Chrome and Chromium browsers such as Microsoft Edge and Brave, on Windows, macOS and Linux. It does not run on phones.

How much does it cost?

It is free to install, and each new account gets 1 hour of Unlimited from its first campaign without a card. Paid plans (monthly, yearly or lifetime) remove limits; prices are shown live on the pricing page. Monthly is a one-time 30 days unless you tick auto-renew at checkout when paying by card; with auto-renew on, you can cancel anytime from Account and keep access until the paid period ends. Yearly, Lifetime and bank-transfer payments never renew.

Files and personalization

Which files can I import?

Excel (.xlsx, .xls), CSV, a public Google Sheets link, pasted numbers, WhatsApp groups, Business labels and saved contacts.

How do variables work?

Every column header becomes a variable in square brackets, e.g. [name] or [order_no]. [name|friend] sets a fallback for empty cells; [if points>=10?Gold|Silver] picks text by condition (operators = != > < >= <= and ~ for contains; no [variables] inside the condition's text); {Hi|Hello} varies the wording.

Can I send attachments?

Yes: images, video and documents such as PDF, with your personalized text as the caption.

Can I schedule campaigns?

Yes, on the Unlimited plan: pick a date and time and the campaign starts while WhatsApp Web is open, within your sending hours and daily limit.

Safety and privacy

Will my number be banned?

WhatsApp can restrict any number that sends unwanted messages. Wassender uses randomized delays, batch rests, daily limits, sending hours and automatic pauses, and skips numbers not on WhatsApp. Message only people who expect you.

How are opt-outs handled?

Replies like STOP or إلغاء add the number to an opt-out list that every future campaign skips.

Does Wassender read my chats or upload my spreadsheet?

No. Spreadsheets, drafts and history stay in your browser's extension storage; cloud backup is off unless you enable Sync. Wassender does not sell personal data.

Does it use the WhatsApp Business API?

No. It works in your own WhatsApp Web session, so there is no API approval or per-message fee from Meta.
