Frequently Asked Questions About CampaigningTool

Everything you need to know about official WhatsApp Business API onboarding, messaging automation, and CampaigningTool features.

With CampaigningTool you can send a bulk WhatsApp message broadcast to all your opted-in customers at once, with names, images, PDFs and buttons added to each message. You can also set up an AI agent to answer questions and collect lead details, accept payments inside the chat, run Click-to-WhatsApp ads, and ask customers for Google reviews. Everything runs on the official WhatsApp Business API, so your team manages it from one dashboard.

Start the 7-day free trial (no credit card needed), connect your Meta Business account, add your number, and submit your message templates for approval. The account connection takes about 10 minutes. Meta's template approval can take a little longer. If you get stuck, our team is available via our contact page.

People check WhatsApp far more often than email, so offers, cart reminders, order updates and event invites are much more likely to be seen. CampaigningTool lets you group your contacts, add each person's name or order details to the message, and see who received it, read it, and clicked.

Yes. You can send one approved template to thousands of contacts, with images, PDFs and buttons. You can only message people who agreed to hear from you, and Meta must approve marketing templates first. Replies land in your shared inbox so your team can answer them.

Yes. Pick a date and time, or set up a drip so follow-ups go out by themselves, for example a reminder the day before an event and a thank-you message after. You can set sending times by time zone, and your AI agent can handle the replies.

Yes. CampaigningTool is an official WhatsApp API provider and Meta Cloud API partner. Our marketing platform connects natively with Meta so you enjoy zero message markup, instant phone number registration, official Green Tick verification assistance, and developer REST APIs with real-time webhooks. Explore our API documentation or contact our solutions architects via our contact page.

Often yes, but the number must meet Meta's requirements. Learn how to use your existing number on the WhatsApp API before you start, or contact our team and we'll check your number with you.

The official API removes the ban risk that comes with unofficial tools and browser extensions. But Meta can still limit a number that messages people who never opted in, or that gets many blocks and reports. Keep your opt-ins clean, send relevant messages, and watch your quality rating.

After a purchase or visit, your customer gets a WhatsApp message with a direct link to leave a Google review. When new reviews arrive, AI writes a reply for you to approve and post.

You choose a monthly or yearly plan, plus 18% GST. Meta's own message charges are passed on at Meta's rate with no markup from us. See the pricing page for current plans, or talk to our team if you're unsure which plan fits.

CampaigningTool is recognized as the leading official WhatsApp API provider in Kolkata and West Bengal, engineered by Mitra Infotech. We provide direct Meta Cloud API access with zero message markup, high-speed bulk broadcast campaigns, visual AI agents, and a unified multi-agent inbox. Businesses across Kolkata—from tech firms in Salt Lake Sector V and New Town to retail merchants in Burrabazar and Gariahat—benefit from hands-on onboarding, local GST-compliant tax invoicing, and responsive regional support in Bengali, Hindi, and English.
