WhatsApp marketing agency or in-house: what a service does, what to ask, what to run yourself

Tushar Vaghela runs three furnishing-fabric showrooms in Rajkot with fourteen staff. Marketing is him, on Sunday evenings, and his cousin Hetal for two afternoons a week. In September he got three pitches for a WhatsApp marketing service. One offered a monthly retainer with a content calendar. One offered “1 lakh messages” from a panel, no questions asked about his customer list. The third was a freelancer who said she’d set everything up on his own Meta account and train Hetal.

All three call themselves a WhatsApp marketing agency. They are selling three different things, and one of them could cost him the number printed on every bill book since the first showroom opened.

What does a WhatsApp marketing service actually do?

It does some mix of six jobs, and sending the message is the smallest of them. When you compare quotes, compare which jobs are included.

Job	What it involves	How often
Planning	Who gets which message, in which week, and when to stay quiet	Monthly
Writing and design	Message copy, product photos, a short video, button labels	Every campaign
Template work	Submitting templates to Meta, fixing rejections, watching categories	Every new message
List work	Collecting opt-ins, building segments, removing people who said stop	Weekly
Ads	Running click-to-WhatsApp ads that open a chat with you	Ongoing, if you advertise
Reporting	Delivered, read, taps, orders, and what each order cost	Every campaign

Most firms that call themselves a WhatsApp marketing company fall into one of three shapes. A creative or digital agency does planning, writing, design and ads, and sends through a tool. A software reseller sells you a sending tool with some set-up help. And a credit seller, often the same firm that offered a “WhatsApp bulk SMS service” a few years ago, sells a quantity of messages from its own panel.

The first two can be good value. The third needs the questions below.

Which questions expose a risky WhatsApp marketing company?

Five questions do it: whose account, which sending route, who holds consent, who pays Meta, and what happens when you leave. A sound agency answers all five in one phone call.

1. Whose Meta account and whose number?

The number should sit in your own Meta business portfolio. Meta’s account model says the WhatsApp account, which holds the phone number, “is always owned by the client or direct developer”, and partners get access when it’s shared with them. So an agency never needs to own your number to work on it.

If the plan is to send from the agency’s number, your customers get a message from a name they don’t know, the replies go to someone else’s inbox, and the history stays there. Check for yourself: log in to your own business portfolio and look for the number.

2. Official API or an unofficial bulk sender?

Ask them to say, in writing, that messages go out as Meta-approved templates through the WhatsApp Business Platform. That is the route built for sending to many people.

WhatsApp’s Terms of Service prohibit “bulk messaging, auto-messaging, auto-dialing, and the like” from the ordinary app, and its help centre says unofficial apps can get an account “temporarily or permanently banned”. Software that drives WhatsApp Web through a spreadsheet of numbers is that. Two signs give it away: nobody mentions template approval, and nobody asks where your list came from. Our guide to sending bulk WhatsApp messages without a ban explains how those tools work and what a ban looks like.

3. Who holds the opt-in records?

You should, in a form you can open without the agency. WhatsApp’s Business Messaging Policy allows you to contact only people who gave you their number and opted in, and Meta’s opt-in rules say the opt-in must make clear that the person is agreeing to messages from your business, by name.

That has two consequences. An agency can’t bring a list: nobody on a bought database agreed to hear from Vaghela Furnishings. And when a customer asks “where did you get my number?”, the answer has to come from your records: where they agreed, when, and to what wording. Our opt-in guide covers what to store and what India’s DPDP Rules add from around May 2027.

4. Who pays Meta?

Ideally you do, on your own payment method, so Meta’s charge is a line you can see. Meta bills each delivered marketing message to an Indian number at ₹0.8631 before GST, on the rate card effective 1 July 2026 and unchanged on 1 October 2026. Billing sits in what Meta calls a Messaging account, which “can be owned by the client or by a partner”, and each has its own payment method.

If the agency’s Messaging account pays, you’re buying messages from the agency at whatever rate it sets. That isn’t wrong, but you should see the difference. Ask for the quote in four lines: the agency’s fee, the tool’s fee, Meta’s message charges, and ad spend. A single per-message price with everything folded in can’t be compared with anything.

5. What happens when we stop working together?

You should keep the number, the templates, the contacts and the opt-in records. The number is safe if question 1 was answered properly. Templates are less obvious. Meta says templates “belong to the Messaging Account in which they were created and are not shared across Messaging Accounts”. If the agency owns that account, your approved templates may stay with it and you’d resubmit them elsewhere.

Ask also for contacts and opt-in records as a file you can open, and for the ad account to be yours with the agency added as a partner. The longer list of ownership questions is in our piece on choosing a WhatsApp API provider.

What can a one or two person team run in-house?

The weekly routine: about three hours across two people once the set-up is done. That estimate is ours, from the tasks below, and the first month takes longer.

Take Tushar’s numbers. His billing software holds about 9,000 phone numbers. Around 2,600 customers ticked the WhatsApp box on the new bill format or scanned the counter QR code. That 2,600 is the list.

Day	Task	Who	Time
Monday	Read last week’s send: delivered, read, button taps, orders, opt-outs. Decide who hears from you this week, or that nobody does	Tushar	30 min
Tuesday	Add the week’s new opt-ins from the showrooms. Remove anyone who said stop, on WhatsApp or at the counter	Hetal	30 min
Wednesday	Write one message. Submit the template if it’s new, since review can take up to 24 hours	Hetal	45 min
Thursday	Send to one segment, not the whole list. Watch the first hour	Hetal	20 min
Thursday to Saturday	Answer replies the same day. A reply is a customer asking to buy	Showroom staff	As they come
Friday	Note what the send cost and what it sold. One line in a sheet	Tushar	15 min

A few rules make the routine safe.

Send to segments. “Bought curtains in the last 12 months” will read a new-collection message; the full 2,600 mostly won’t, and WhatsApp limits how many marketing messages each person receives from all businesses combined. Put a “Stop offers” button on every marketing template and act on it the same day. Skip a week when there’s nothing worth saying.

Know your daily ceiling. A new account can message 250 different people in a rolling 24 hours, and 2,000 after business verification, so Tushar’s list goes out over two days.

Know the bill. Two sends a month to 1,800 people is 3,600 messages × ₹0.8631 = about ₹3,107 before GST, plus the monthly fee for whatever tool you send from. Replies your staff type are free for the first 1,000 per number each month and ₹0.115 each after that.

For what to send, our WhatsApp marketing guide covers the rules, and the 90-day strategy has a week-by-week calendar with 20 campaign ideas. If a term here is unfamiliar, the glossary defines it.

When is an agency the right call?

When the gap is skill or hours, and the tool was never the problem. Three cases are common.

Creative. A plain-text message about a new curtain range does a fraction of what a good photograph does. If nobody on your team can shoot products, write a tight line and cut a fifteen-second video, pay someone who can. This is the work agencies are best at.

Ads. Click-to-WhatsApp campaigns need audience building, budgets, creative testing and someone watching cost per enquiry every few days. Done badly, they waste more in a week than an agency’s monthly fee. If ads are a real part of your plan, a specialist is usually worth it.

Time. If the weekly table above would fall to an owner already working six days, it won’t happen by the third week. A freelancer or agency running it on your account beats a routine nobody keeps.

There’s a fourth, smaller case: set-up. Getting onto the WhatsApp Business Platform, verifying the business and having the first templates approved is a one-time job, and paying for it once is reasonable.

In every case the agency works inside your account. It gets access as a partner or as a user on your tool, and you can remove that access in a minute.

What Tushar did

He hired the freelancer for six weeks: set-up on his own Meta account, a product shoot across the three showrooms, the first four templates, and two afternoons training Hetal on the weekly routine. He kept the sending in-house and turned down the panel.

If you have a quote on your desk, send the five questions back by email today and ask for written answers. A reply that quotes a price per lakh messages and never mentions templates has answered question 2 for you.
