Home / WhatsApp bulk message sender
A bulk sender is only useful if the messages arrive and the number survives. WatsBizz sends personalised broadcasts from your own linked WhatsApp number, paced deliberately rather than blasted, with delivery and read reporting for every campaign.
Import your contacts, pick or write a template, choose who receives it, and either send now or schedule it. Each recipient gets their own message with their own details merged in — not an obvious mass broadcast.
Sending a few thousand messages in a burst from a regular WhatsApp number is the fastest way to get it restricted. Campaigns are therefore throttled with randomised gaps rather than sent as fast as the connection allows.
Alongside that: a warm-up mode builds a new number’s activity up gradually before you run real campaigns, and device health and ban risk are monitored so problems surface early. The Opt In/Out module captures opt-out keywords once you enable it for a linked number, and those contacts are then skipped on later campaigns — it is per-device setup, and the suppression list is kept per number, so configure it on each number you send from.
This is the part most bulk-sender pages skip, and it matters more than any feature on this one. WhatsApp is a personal channel, and recipients report unwanted messages quickly — enough reports and the number is restricted, regardless of which software sent them.
Campaigns to your own customers — people who bought from you, enquired, or gave you their number — perform well and rarely cause problems. Purchased lists and scraped numbers are a different activity with a predictable ending, and no amount of throttling prevents it. Every message should also make it obvious how to stop receiving them.
Message allowances are monthly and scale with the plan: Starter includes 2,500 messages a month with 2 linked devices, Premium 5,000 with 5 devices, and Business 10,000 with 10 devices. Linking more devices spreads sending across several numbers, which is gentler on each one than pushing everything through a single number.
It depends on the plan: 2,500 on Starter, 5,000 on Premium and 10,000 on Business, per month. Additional linked devices let you spread that volume across more than one number.
Personalised. Merge fields insert each contact’s name and any custom fields you store, so every recipient receives their own message.
Yes. Campaigns can be queued for a specific time and resume automatically if the server restarts before they finish.
Campaigns are throttled with randomised delays, new numbers can be warmed up gradually, device health and ban risk are monitored, and opt-outs are excluded automatically. The decisive factor is still only messaging contacts who opted in.
Yes, contacts can be imported from CSV, and there is a Google Sheets sync if you would rather keep the list there.
