Rocket Sender - WhatsApp Sender Free

Free tool to send personalized WhatsApp messages with templates, CSV lists, and scheduling.

Rocket Sender helps you prepare and send personalized messages from your own WhatsApp Web session. It is designed for consent-based customer follow-ups, reminders, support updates, and team communication. Key features: • Manual or Excel recipients: Enter phone numbers manually or import an .xlsx or .xls workbook. • Excel personalization: Personalize messages using fields from each imported row. • Messages and attachments: Send text with optional attachments selected from your device. • Sending intervals: Set a randomized interval between sending actions. • Progress controls: Monitor local progress and pause or resume the active queue. • Local result export: Export successful, failed, and not-sent results to an Excel file. • No Rocket Sender account required: Use the Extension with your existing WhatsApp Web session. How it works: 1. Open WhatsApp Web and sign in to your own WhatsApp account. 2. Open Rocket Sender from the WhatsApp Web toolbar. 3. Enter recipient numbers or download and complete the included Excel template. 4. Add your message, optional attachments, and sending interval. 5. Review the recipient count and message content, then start sending. 6. Monitor progress, pause or resume when needed, and export the local results. Privacy: • Recipient numbers, message content, Excel fields, attachments, queue state, and sending results are processed primarily in your browser. • Message drafts, selected attachments, and sending preferences may be stored locally using Chrome extension storage. • Rocket Sender does not upload analytics, diagnostic logs, WhatsApp account identifiers, recipient data, message content, or attachments to developer-controlled analytics or application servers. • A small validated CSS selector configuration is requested over HTTPS to maintain compatibility with WhatsApp Web. The response cannot contain executable code, HTML, advertisements, messages, or links. • When you start sending, the selected content is transmitted through your WhatsApp Web session to WhatsApp and the recipients you selected. Responsible use: • Only contact people who have agreed to receive your messages. • Avoid unsolicited, misleading, or abusive messaging. • Follow WhatsApp's Terms of Service and all applicable laws. • Rocket Sender cannot prevent account restrictions, guarantee message delivery, or bypass WhatsApp enforcement. Rocket Sender does not require a separate product account or payment. A normal signed-in WhatsApp Web session is required to use the core functionality.
