What it does

A practical sender for people who already use WhatsApp Web.

The extension turns a contact sheet into a controlled WhatsApp Web sending queue. You write one message template, import or paste contacts, choose pacing settings, and monitor the send from the popup. It is made for legitimate updates, follow-ups, invites, and small outreach workflows where manual sending becomes repetitive.

Key features

Everything users need before they trust a sender.

These are based on the actual extension flow: popup import, options page, message resolver, queue, and send log.

CSV

Import contacts from CSV or XLSX

Upload spreadsheets with columns like phone and name. The importer recognizes common number headers, reads names when available, and adds valid rows to the send list.

Name

Personalize each message

Add a name beside each number and use the template field to send messages that feel direct. The extension replaces the name placeholder for each recipient before adding it to the queue.

A/B

Rotate message variations automatically

Use variation blocks such as {{Register now|RSVP now|Join now}} to rotate copy across sends. Options are shuffled and reused carefully so every recipient does not get the exact same line.

File

Send attachments and action buttons

Attach supported media or documents, add captions, and configure up to three buttons for links, phone actions, or quick reply style interactions where WhatsApp Web supports them.

6-15s

Add random delays between messages

Choose a min and max delay window, or use a fixed interval. Each queued message gets its own pacing value before the next send is attempted.

Batch

Use batch pauses for controlled sending

Pause after a random number of messages and sleep for a random duration between configured ranges. The popup shows whether it is waiting for a normal delay or a batch pause.

Control panel

Built-in controls for real sending sessions.

During a run, the popup tracks processed, sent, failed, remaining, duplicate, and queued contacts. You can pause, resume, or cancel the queue without losing sight of progress.

Workflow

From spreadsheet to send queue in minutes.

1

Open WhatsApp Web

Log in to WhatsApp Web first, then open the extension popup.

2

Draft the message

Add personalization, variations, attachment, buttons, country prefix, and pacing settings from Options.

3

Import or paste contacts

Upload CSV/XLSX or paste numbers manually. Duplicate numbers are counted and logged.

4

Send and monitor

Start the queue, watch progress, pause when needed, and review sent or failed logs afterward.

Use cases

Designed for useful updates, not unwanted messages.

Use it when people expect to hear from you: college clubs, hackathons, product launches, customer onboarding, event reminders, founder follow-ups, sales check-ins, and community announcements.

Responsible use

Send only to people who should receive your message.

The extension gives you pacing controls, batch pauses, and logs, but it does not make unwanted outreach acceptable or guarantee account safety. Keep messages relevant, respect opt-outs, test on your own number first, and use WhatsApp responsibly.
