Rocket Sender is a Chrome extension that streamlines WhatsApp Web communication for consent-based follow-ups, reminders, and support updates. It lets you import recipient lists from Excel, personalize messages with row-specific fields, attach files, and set randomized sending intervals. All processing happens locally in your browser, ensuring privacy. Monitor progress, pause or resume queues, and export results to Excel. No separate account needed—just your existing WhatsApp Web session.
