Advanced Audience Segmentation

Send to exactly the right people. Segment by labels, purchase history, last interaction date, or any CRM field. No spray-and-pray campaigns.

Schedule & Timing Controls

Pick the exact date and time for your campaign. Set custom messaging windows to avoid sending outside business hours. Stay compliant without manual checks.

Smart Re-Targeting

After your first send, re-target only those who didn't open, only those who clicked, or only those who replied. Double the efficiency of every campaign.

Per-Message Delivery Analytics

Track delivered, read, clicked, and replied, per message, per campaign. Export to CSV. Know your ROI down to the last rupee.

How It Works

A campaign, from list to delivery report

Sending to thousands of people on WhatsApp is nothing like blasting an email list. The rules are stricter and the cost of getting it wrong is higher. Here is how a campaign runs on the platform.

1
Pick exactly who hears from you. Filter your contacts by tag, last purchase, city, language, or any custom field. A good list is the difference between a campaign people welcome and one that gets you reported, so this step matters more than the message itself.
2
Use an approved template. Marketing messages on WhatsApp have to run through pre-approved templates. You write it, submit it, and once Meta clears it you can send it to your whole list. The platform shows you the status so you are never guessing whether a template is live.
3
Schedule it for the right moment. Pick the date and time, and set windows so nothing goes out at 2am. A festival offer that lands at the right hour reads as helpful. The same message at the wrong hour reads as spam.
4
Watch it land in real time. As the campaign sends, you see delivered, read, clicked, and replied counts climb. No waiting until the next morning to find out how it went.
5
Re-target the people who matter. Send a gentle follow-up only to those who did not open, or a stronger offer only to those who clicked but did not buy. One campaign becomes a sequence, and your numbers climb without burning your whole list.
What You Can Send

Campaigns that earn a reply, not a block

Offers and promotions

Festival sales, launch announcements, and limited-time discounts, sent to the segment most likely to act on them. Add a button that opens a chat or a payment link and you turn a broadcast into a conversation.

Reminders and alerts

Appointment reminders, renewal nudges, restock alerts, and event invites. Utility messages cost a fraction of marketing ones and reach people on the channel they actually check.

Re-engagement

Win back customers who have gone quiet. Target people whose last order was months ago with a reason to come back, and measure exactly how many returned.

Feedback and reviews

Ask for a rating or a review at the right moment after a purchase. WhatsApp reply rates beat email by a wide margin, so you hear from far more of your customers.

Updates and newsletters

Share news, tips, or a monthly roundup with the people who opted in. Keep it useful and your open rates stay high, because people read WhatsApp in a way they no longer read inboxes.

Personalised at scale

Drop in each person's name, order ID, city, or appointment time automatically. A thousand messages that each read like they were written for one person.

Staying On The Right Side Of Meta

Deliverability is something you protect, not something you assume

WhatsApp gives every business number a quality rating. Send messages people want and that rating stays green, which keeps your sending limits high. Send to people who never opted in and the rating drops, your limits shrink, and eventually the number gets restricted.

The segmentation and re-targeting tools exist for exactly this reason. By sending the right message to the right segment instead of blasting everyone, you keep your block rate low and your account healthy. Good targeting is not just better marketing, it is what keeps you able to send at all.

Who Relies On It

Built for teams that send at volume

E-commerce brands running festival sales, drops, and cart recovery to lists in the thousands.
Service businesses sending appointment and renewal reminders that cut no-shows and churn.
Agencies managing campaigns for many clients from one place, with clean reporting per account.
Event organisers pushing invites, reminders, and last-minute updates to attendee lists.

What It Costs

Working out the cost of a campaign

The price of a bulk campaign is mostly the per-message charge that WhatsApp sets, not a platform markup. WA.Expert passes Meta's rates through without adding to them. Here is how the math works on a paid plan, using current rates.

A marketing campaign to 5,000 people

Marketing rate per message₹0.86
Recipients5,000
Message charges₹4,300
Roughly per campaign₹4,300

That is the message cost. Your platform plan is a separate, fixed quarterly or annual fee on top.

A utility blast to 5,000 people

Utility rate per message₹0.115
Recipients5,000
Message charges₹575
Roughly per send₹575

Reminders and alerts qualify as utility messages, which is why they cost a fraction of marketing sends.

Rates shown are current at the time of writing and are set by WhatsApp, not by WA.Expert. The Starter plan uses slightly higher message rates and the paid plans use the lower ones shown here. Always check the pricing page for the live figures before you budget, and remember that 18% GST applies to the platform fee.

Is It Legal

Bulk WhatsApp is allowed, with one firm condition

Sending marketing messages to people in bulk on WhatsApp is permitted, as long as those people opted in to hear from you. That is the line. Opt-in means the person gave you their number and agreed to receive messages, through a form, a checkbox at checkout, a keyword they sent you, or a clear request. Scraping numbers or buying a list and blasting it is against WhatsApp's rules and will get your number restricted quickly.

This is different from bulk SMS in India, where DLT registration with the telecom regulator governs sending. WhatsApp runs its own approval system instead, through pre-approved message templates and your number's quality rating. You do not register on the DLT portal for WhatsApp, but you do have to keep your opt-in clean and your templates compliant.

What Counts As Opt-In

Ways people can agree to hear from you

A checkbox at checkout or sign-up where they agree to WhatsApp updates.
They message your number first, or send a keyword from an ad or QR code.
They fill a form, online or on paper, that clearly mentions WhatsApp contact.
They ask you directly to send updates, offers, or reminders on WhatsApp.
How It Compares

Bulk WhatsApp against the channels you already use

  Bulk WhatsApp Bulk SMS Email
Typical open rateVery high, most messages get readHigh, but no media or buttonsLow, often a fraction are opened
Rich contentImages, buttons, catalogues, formsPlain text, character limitsFull design, but lands in promotions
Two-way repliesYes, becomes a conversationRarely practicalSlow, separate thread
Best forOffers, reminders, recovery, supportOTPs, simple alertsNewsletters, long content

None of these fully replaces the others. The point is that WhatsApp gets read in a way email no longer is, and it carries far more than SMS can, which is why it has become the channel of choice for offers, reminders, and anything that benefits from a reply.

Avoid These

The mistakes that get a number banned

Sending to a bought list

Messaging people who never opted in is the fastest way to a flood of blocks and a restricted number. No tool can protect a number from a cold list.

One message to everyone

Blasting your whole database the same offer ignores who actually wants it. Irrelevant messages get reported, and reports drag down your quality rating.

No easy way to opt out

If people cannot stop your messages, they block you instead, which hurts far more than an unsubscribe ever would. Always make leaving simple.

Too much, too often

Daily promotional messages wear people out fast. A steady drip of useful, well-timed sends keeps your rating healthy and your audience listening.

Sample Templates

What a good bulk message looks like

Offer

Hi {name}, our monsoon sale is live. Flat 25% off everything till Sunday. Tap below to shop before your favourites sell out.

Reminder

Hi {name}, this is a reminder of your appointment on {date} at {time}. Reply 1 to confirm or 2 to reschedule.

Cart recovery

Hi {name}, you left {product} in your cart. It is still available. Complete your order in the next 24 hours and we will hold it for you.

Each of these uses a personalised field, gives a clear reason to act, and respects the reader's time. That combination is what earns a reply instead of a block. Templates like these need WhatsApp approval before sending, which the platform walks you through.

FAQ

Bulk WhatsApp messaging questions, answered

How many messages can I send in a day?
+
Your daily limit is set by WhatsApp based on your number's quality rating, and it grows as you build a track record of good sending. New numbers usually start at 1,000 business-initiated conversations a day and move up through tiers as your rating stays healthy. Sending well-targeted messages to people who opted in is what unlocks the higher tiers.
Why do marketing messages need approved templates?
+
WhatsApp requires any business-initiated message to use a template it has reviewed first. This is how the platform keeps spam off the channel. You submit your template, it is usually reviewed within a short window, and once approved you can send it as often as you need within your limits.
What does a campaign actually cost?
+
You pay WhatsApp's per-message charge, which differs for marketing, utility, and authentication messages, plus any platform fee for your plan. WA.Expert does not add a markup on the WhatsApp charges. The pricing page lists current rates so you can work out a campaign's cost before you send it.
Can I personalise each message?
+
Yes. You can pull in any field you store about a contact, such as their name, city, order ID, or appointment time, and each recipient sees their own details. This is built into the template, so it happens automatically across the whole send.
How do I avoid getting my number blocked?
+
Send only to people who agreed to hear from you, keep your messages relevant, and make it easy to opt out. Use the segmentation tools so you are not sending the same thing to everyone. The platform's re-targeting features help you send less but better, which is exactly what protects your quality rating.
Can I see who opened and clicked?
+
Yes. Every campaign reports delivered, read, clicked, and replied figures per message, and you can export the data to CSV. You can then build a follow-up campaign that targets only the people who took a specific action.
