Common questions about sending bulk WhatsApp messages with iSend.
Bulk WhatsApp messaging is the practice of sending one message to many customers at once over WhatsApp using the official WhatsApp Business API. Unlike the free WhatsApp Business app — which is designed for one-to-one chats — bulk messaging lets you send approved template messages (promotions, order updates, reminders) to your entire customer list from a single dashboard.
Yes — when you use the official WhatsApp Business API and follow WhatsApp's policies. iSend is an official WhatsApp Business API provider. We require opt-in consent, use approved message templates for messages sent outside the 24-hour customer service window, and support opt-out management so your campaigns stay compliant.
No. You can start sending immediately through iSend's verified shared WhatsApp Business API number — no Meta Business account or Meta credit card required. If you prefer, our team can also help you connect your own dedicated WhatsApp Business API number.
iSend uses simple monthly plans that include message units — 1 unit equals 1 approved WhatsApp template sent to a customer. Customer replies and 24-hour chat conversations are free, and unused units roll over to the next month. WhatsApp delivery via iSend's shared number is included in your plan. If you connect your own Meta number, Meta bills its own conversation charges separately.
It depends on your plan — from 1,000 units per month on Starter up to 50,000 on Enterprise, with top-up packs whenever you need more. You can send a campaign to your entire opted-in audience in a single broadcast; actual throughput scales with your plan and Meta's rate limits.
Yes. You can insert the customer's name and other attributes into your templates so each recipient gets a personalised message while you send to thousands at once. You can also segment your audience (by location, purchase history, tags) so different groups receive different messages.
Common uses include order confirmations and delivery updates, flash sales and promotions, event invitations and reminders, appointment reminders, birthday and loyalty offers, re-engagement campaigns, and product launches. It works for retail, e-commerce, schools, event organisers and service businesses.
Both let you reach many customers at once, but WhatsApp supports rich media (images, buttons, documents), interactive replies and two-way chat, while SMS is a simple text message of 160 characters. Many businesses use WhatsApp for engagement and rich messaging, and SMS as a reliable fallback for customers who do not use WhatsApp.
