Send personalized WhatsApp broadcasts to thousands of contacts at once, using Meta-approved templates and the official API — not a risky automation script.
Most “bulk WhatsApp sender” tools promise mass messaging but quietly put your number at risk — unofficial APIs and browser-automation tricks get flagged and banned by WhatsApp within days. Growby takes a different approach: bulk sending built entirely on the official WhatsApp Business API, so you can message thousands of contacts at once without gambling on your account.
The everyday friction that slows businesses like yours down.
Unofficial bulk senders and browser-automation tools get flagged by Meta within days, and losing a WhatsApp Business number mid-campaign can wipe out an entire customer relationship overnight.
A copy-pasted blast to thousands of contacts reads as impersonal, gets ignored, and can trigger recipients to block or report the number, dragging down your quality rating.
Sending too fast, ignoring rate limits, or using unapproved message formats causes large sends to stall halfway through or get silently throttled by WhatsApp.
Real workflows Growby customers run every day.
Announce a sale, new product, or limited-time offer to your entire customer list segmented by location, purchase history, or tags, in one scheduled send.
Push shipping confirmations, delivery updates, or event reminders to thousands of recipients the moment a status changes, without your team sending them one by one.
Reach dormant leads or lapsed customers with a targeted broadcast, then automatically route any replies into a shared inbox for follow-up.
Send location-specific messages — store openings, local offers, branch alerts — to the right contact segment across dozens of branches from a single campaign.
Broadcast a quick feedback request after a purchase or service visit, and collect structured replies automatically instead of chasing responses manually.
Queue a broadcast to go out at the exact date and time your audience is most likely to read it, instead of manually triggering every send.
Every message uses Meta's official WhatsApp Business API and approved templates, so you're never one policy update away from a shutdown.
Sends are automatically queued and throttled to stay within WhatsApp's rate limits, so a 50,000-contact broadcast goes out reliably instead of failing partway through.
Insert variables like name, city, or order number from your contact list, so every recipient gets a message that reads as if it were written for them individually.
See delivered, read, and reply rates per campaign in real time, so you know exactly which broadcasts are working and which need a rewrite.
