WA Bulk Sender — Free WhatsApp message blaster (no number saving)
Overview
Send personalized WhatsApp Web messages to a list of numbers without saving contacts. Placeholders, media, delays. 100% local, free.
WA Bulk Sender lets you send one personalized message to a whole list of phone numbers on WhatsApp Web — without saving any of them as contacts. Paste your list (or load a .csv / .txt), write your message, set a comfortable sending pace, and press Start. Everything runs locally in your browser. 100% FREE — every feature below is included. No quota, no license key, no account, no sign-up, and no telemetry. — WHAT IT DOES — • Bulk send without saving contacts Paste numbers or load a .csv / .txt list. Each number is messaged directly, so your address book stays clean. • Personalization placeholders Use {name} for the first field, {1} {2} {3}… for fields by position, and {number} for the recipient's number. Example: a line "447700900000, Bob, VIP" with message "Hi {name}, your tier is {2}" sends "Hi Bob, your tier is VIP". • Optional media Attach one image, video, or document. Your message text becomes the caption. • Smart pacing Set a randomized minimum/maximum delay between sends, plus a periodic cooldown (pause every N messages for X seconds). Randomized, human-like pacing reduces the chance WhatsApp flags the account. • Live progress that survives popup close Watch sent / failed / total counts, a progress bar, and a running log. The send loop runs in the page, not the popup — so you can close the popup, reopen it, and the progress is still there. Stop any time. — HOW TO USE — 1. Open https://web.whatsapp.com and log in (scan the QR code). 2. Wait for your chats to finish loading. 3. Click the WA Bulk Sender icon. 4. Paste your recipients (one per line, international format, no "+"): The first comma-separated value is the phone number; the rest are fields for your placeholders. 5. Write your message, optionally attach media, and set your pacing. 6. Press "Start sending" and watch the progress. — PRIVACY — • 100% local. Your numbers, message, and media never leave your browser. There is no server, no analytics, and no tracking. • The only site the extension touches is web.whatsapp.com. • Permissions: "storage" (to keep send progress so the popup can reopen) and "tabs" (to find your active WhatsApp Web tab). Nothing else. — RESPONSIBLE USE (please read) — Sending unsolicited bulk messages can violate WhatsApp's Terms of Service and may get your number rate-limited or banned, regardless of pacing. Only message people who expect to hear from you. This tool includes no list-buying, no scraping, and no number harvesting — it simply sends your message to the list you provide. You are responsible for how you use it. — NOTES — • Works on WhatsApp Web in Chrome. Your WhatsApp tab must stay open while sending (closing it stops the run; progress so far is kept). • Built on the open-source WPPConnect wa-js library. A major WhatsApp Web update may temporarily affect it until the library updates. A free plugin provided by Extension.software. Check out our other free plugins at https://extension.software/apps
