Best Bulk WhatsApp Message Sender Software in India

Whichever one keeps your line alive while it reaches thousands. That rules out anything puppeting an everyday account through WhatsApp Web and leaves Business API software. Within that field, KaamGPT tidies 20,000-row files, subtracts refusals gathered on every channel, spaces slices to Meta's ceiling, prices a send in rupees before release and routes answers to a team desk. Hold any rival to those tests during a free trial.

Messaging at volume is permitted on WhatsApp's official Business API, provided every recipient consented to messages from your particular business and Indian law on consent and notices is respected. What WhatsApp's terms forbid is automated mass sending from a consumer or Business-app account outside the authorised API. Every KaamGPT message is passed to one of two sanctioned gateways, MSG91 or Meta's Cloud API.

Plenty of tools marketed as bulk senders steer a normal account over WhatsApp Web or a second linked handset, row after row. WhatsApp treats that as automation outside its API, and strangers who never stored the number block and report it. Either one leads to restriction or a ban. On the Business API the safeguards differ: templates, recorded consent and a quality grade Meta displays openly.

Over any rolling 24 hours Meta counts the separate people a business portfolio reaches outside open service windows, and caps that count. Fresh portfolios begin at 250 per day; verification, or 2,000 well-received delivered messages inside 30 days, raises that to 2,000, and steady quality can lift it further, through 10,000 and 100,000 to no cap. Every line in the portfolio shares the figure, which is why KaamGPT shows the tier and lets you cap each line.

Yes. Devanagari Hindi is a supported template tag, sitting beside English and English (US) as the only three choices, and Devanagari Hindi suits most readers across Uttar Pradesh, Bihar, Madhya Pradesh, Rajasthan and Delhi. Write genuine Hindi rather than another tongue typed in Devanagari, because Meta checks the text against the language tag chosen.

Not under those language tags. The editor's menu stops at Hindi, English and English (US). Firms serving Tamil, Telugu, Kannada, Malayalam, Bengali, Marathi, Gujarati, Punjabi, Odia or Assamese readers therefore send English or Hindi, sometimes adding the regional language in Roman letters, which Meta judges against the tag. Once a buyer writes, your staff can reply in Tamil, Bengali or any language at all for 24 hours, because chat is not a template.

Think of it as a rent and a postage bill. The rent is the plan (₹0 on Free, ₹999 a month on Starter) and covers logins, storage and every app. Then every message is debited separately from coins bought over UPI, at whatever Meta's category commands, so a Pongal offer to Madurai buyers costs more per head than a shipping alert or an OTP. The likely spend is shown before release; the <a href="/pricing">pricing page</a> carries the full tier table.

No. There is no monthly bundle on any plan; each WhatsApp message consumes wallet coins. If the balance obviously cannot pay for the whole list, nothing starts, and one whose coins give out midway simply waits, frozen, until you recharge by UPI. If you linked your own line, Meta may also bill certain charges straight to your own Meta account.

Conversation-based billing ended on 1 July 2025; Meta now prices every template that actually reaches a phone. Category sets the price, and so does the destination country, which is why every +91 recipient from Srinagar to Kanniyakumari falls under India's rate card. Marketing templates are always billable, while Meta lets utility templates sent inside an open service window go free. KaamGPT's wallet displays the per-category spend before you release a send.

Meta requires a clear yes from each person to messages from your business by name, collected however suits you: a web form, an SMS, an IVR call flow, or a paper or face-to-face sign-up at a counter. Meta also recommends separate opt-ins for different message types. Before importing into KaamGPT, add a column noting where each contact agreed, so the trail outlives staff turnover.

The upload will accept any CSV, but a purchased list breaks Meta's opt-in rule, since nobody on it ever said yes to your firm. They are also the likeliest to block and report, which sinks the quality grade that governs your daily ceiling. Grow the list from customers, enquiries and counter sign-ups instead; it will be smaller and far kinder to the line.

Each CSV may carry 20,000 rows. Ten-digit Indian mobiles gain +91 automatically, every handset gets one message however often it is listed, and the preview counts heads exactly as dispatch will. Bigger lists arrive as several files or as CRM records, then combine through saved lists and conditions inside a single campaign.

Yes. Release a portion, perhaps the first five hundred names this morning and everyone after them the next day, then free the next portion from the same campaign. That keeps a long list inside Meta's daily ceiling and lets you check the quality grade between portions. A Business API campaign cannot yet be timed for later from the interface, so each portion is released by hand.

A single reply does it. Reply STOP, opt out, unsubscribe or cancel, and that buyer vanishes from future sends without anyone at head office lifting a finger. Ahead of every later batch it also removes people who quit your emails, carry a do-not-contact marker or asked KaamGPT's voice agent not to ring again. For a chain with branches in several states, a single refusal then holds everywhere without staff relaying it.

Inside the run, a temporary fault gets up to three more tries. Anything still bouncing is listed with its reason, and the most frequent reasons are summed up in the report. Mend the cause, perhaps a mistyped number or a lapsed template, then send again to the bounced recipients alone, so buyers already reached are neither charged for nor pestered twice.

Six running tallies, from queued and handed over through reached, opened and answered to bounced, plus the leading bounce reasons. Every tally exports as a spreadsheet whose times follow IST. KaamGPT keeps no record of link clicks, run split tests or build click-to-WhatsApp ads, so national teams generally judge a send by replies and by the calls the opened-but-silent sheet produces.

Yes. A workspace can carry a line for Patna, another for Pune and a third for head office, the head-office line set as default and a per-day cap fixed for each. Remember that Meta's limit belongs to the business portfolio, not the line, so every number in it draws on the same allowance. The Sending routes page tells you how each line is doing, and shows Meta's grade and tier for it when Meta supplies them, which helps a Delhi head office stop one region's send crowding out another's.

For most senders the Meta Cloud route offers more. Your existing line joins through Embedded Signup, headers may be pictures, clips or PDFs, carousels work, and the chatbot can take first replies. On MSG91 it is KaamGPT's team who connects the line, and that route's templates are made in the MSG91 panel, text only with no media header, fine for words-only notices. Most firms begin on Meta Cloud.

Leave a few days. On a Meta Cloud line a KaamGPT checker reads the draft first and may adjust its category or a phrase, and then Meta rules. A webhook usually brings Meta's answer; failing that, KaamGPT polls every six hours, or someone presses Sync. Turned-down drafts show why Meta refused and may be amended and filed again, so lodge Pongal, Navratri or Diwali wording well ahead.

In most cases. Meta's Embedded Signup runs inside KaamGPT's screens, KaamGPT being one of Meta's Tech Providers, and your line migrates there. A number still active on the WhatsApp or WhatsApp Business phone app must first go through Meta's own steps for moving onto the platform. Until your line is ready, a KaamGPT-owned number can be lent to the workspace.

No. Everything runs from KaamGPT's lone Bengaluru office; there are no regional branches and nobody in the field. Set-up happens online through Meta, and help is a call or WhatsApp away on +91 79767 82366, so a Guwahati distributor, a Ludhiana trader and a Mumbai label all receive the same service.

Yes. Developer API keys limited by scope let an ERP, billing package or web store push an approved template, ask after a message's delivery state, or create and check one-time passwords. Keep dispatch and payment notices on that route and leave promotions to campaigns in the app, so transactional messages never wait behind a large promotional slice.

Your own people, from a common team desk. Any chat may be passed to a colleague, given labels and private notes, starred, filed away or marked done, with the CRM card alongside, and a new buyer message can alert as many as ten staff handsets over WhatsApp. If the line sits on Meta Cloud, KaamGPT's chatbot can take the first, routine questions and then hands over the moment a colleague types.

Usually. Free costs ₹0 and includes every app, a five-person team and half a gigabyte, which covers connecting one number, getting a first template passed and messaging a modest batch of consenting buyers. Messages still draw wallet coins. Each paid plan can also be run free for 14 days, and a Coimbatore or Cuttack owner can <a href="/signup">open a workspace</a> alone, no sales call required.

Treat each region as a separate audience. Tag contacts by state and preferred language, build festive templates per region, and release slices in the weeks of Pongal, Bihu, Onam, Navratri, Durga Puja or Chhath instead of one national blast. Keep dispatch notices on their own templates, and watch the shared portfolio ceiling so one region's slice leaves room for the next.

No, and no straight provider can promise it. A retailer's handset may be dead for the day, a landline may have crept into the file, and Meta can throttle a portfolio whose quality grade has slid. KaamGPT shows precisely who bounced and why, retries passing faults, and lets you send again to the bounced numbers alone once the cause is mended.
