Bulk WhatsApp marketing: frequently asked questions
Can I send bulk WhatsApp messages to my customer list?
Yes, through the official WhatsApp Business API, using Meta-approved message templates, to contacts who opted in to receive messages from your business.
How many WhatsApp messages can I send per day?
This is set by your messaging tier, not by your provider. New numbers usually start at 250 unique customers in 24 hours, then move up automatically to 1,000, 10,000, 100,000 and finally unlimited as you send good quality messages and keep your quality rating high.
What is the difference between the official API and bulk WhatsApp sender software?
Unofficial bulk senders work through unauthorised channels, break WhatsApp's terms and regularly get numbers permanently banned. The official API is sanctioned by Meta, gives you delivery and read reports, and carries no ban risk when used correctly.
How much does a bulk WhatsApp campaign cost?
Meta charges for the messages and TrendingBulb charges for the platform. In India, Meta's current rates are about Rs. 0.86 per marketing message and Rs. 0.12 per utility message, so a marketing campaign to 1,000 contacts costs roughly Rs. 860 in Meta charges. Platform plans start at Rs. 999 per month after a free trial. Rates differ by country and are set by Meta, so confirm current pricing with our team.
What results can I expect from WhatsApp marketing?
Results depend on your offer, how recently your contacts opted in and how well your list is segmented, so no provider can promise a specific figure. WhatsApp typically sees far higher open rates than email, and our team can share case studies from businesses in your industry so you can judge realistic outcomes.
