Rocket Sender is a free WhatsApp Web bulk messaging Chrome extension that lets you send personalized text, images, videos, and documents to multiple contacts while controlling send speed to reduce ban risk.
What is Rocket Sender?
Rocket Sender is a WhatsApp Web bulk messaging tool built as a Chrome extension. It imports contacts from CSV files or manual entry, accepts custom messages with placeholders and attachments (images, videos, documents up to 16 MB), and outputs sent messages with real-time delivery tracking. It is developed by the Rocket Sender team and requires only an active WhatsApp account and WhatsApp Web login.
Key Features
- Bulk contact import — Upload existing contact lists via CSV or manually enter phone numbers; no limit on list size beyond daily sending caps.
- Personalized messages with placeholders — Use variables like
{name} or {timestamp} so each recipient sees unique content, reducing spam flags.
- Attachment support — Send images, videos, and documents (max 16 MB per file) alongside text messages.
- Adjustable sending intervals — Set a random time delay between messages to mimic human behavior and lower ban risk.
- Real-time sending status — Track which messages were delivered, failed, or pending during a campaign; after sending, view a checklist of failed contacts.
- Daily message caps — 50 messages on the first day, 300 messages per day from day two onward, enforced to protect account safety.
- Built on WhatsApp Web — Works as a Chrome extension that opens WhatsApp Web in one click; syncs with mobile phone chats.
Who is it for?
- Small business owners — Send appointment reminders, order confirmations, or promotional offers to opt-in contact lists without switching apps.
- Customer support teams — Broadcast updates or FAQ answers to hundreds of customers while tracking which messages failed.
- Marketers running consented campaigns — Personalize outreach with placeholders and attachments (e.g., holiday greetings with a flyer) while abiding by WhatsApp’s anti-spam policies.
- Sales representatives — Reach leads with tailored product information using CSV-imported contact lists and monitor delivery status.
What can you do with Rocket Sender?
- Send bulk campaign messages: Compose a message, attach a file, upload a contact CSV, adjust send speed, and click send. Real-time status shows progress.
- Personalize each message: Use placeholders like
{first_name} to address recipients individually, then attach their relevant PDF or image.
- Avoid WhatsApp bans: Set a random interval (e.g., 10–30 seconds) and use unique placeholders so messages don’t look identical; never exceed 300 messages per day after the first 50.
How does Rocket Sender work?
- Import contacts — Upload a CSV file or manually type phone numbers into the extension.
- Compose message — Write your text, add placeholders (e.g.,
{name}), and optionally attach an image, video, or document.
- Adjust sending settings — Choose a time interval (minimum suggested: a few seconds) and click “Send.”
- Monitor and review — Watch progress in real time; when finished, see a list of failed contacts for retry.
Pricing
Rocket Sender is free with no paid tiers. Daily message limits (50 first day, 300 thereafter) are enforced to protect account safety.
