Choosing between RCS and WhatsApp for your next marketing campaign?
RCS campaigns reach customers in supported phone messaging apps, while WhatsApp campaigns reach them inside WhatsApp. To choose between them, check which customers you can reach, how they can respond and what the full campaign will cost.
If your customers already ask questions and buy through WhatsApp, start by considering WhatsApp for your marketing campaign.
It connects your offer with catalogs, Flows and ads that open a chat. RCS is worth considering when you want to add branded cards and reply options to an existing SMS audience that your provider can reach.
Both channels support conversations, so compare the customer journey you can actually deliver.
Let’s compare RCS vs WhatsApp marketing for businesses in India, work through a collection-launch example, and calculate what you need to budget before choosing a channel.
What Is RCS Business Messaging?
RCS stands for Rich Communication Services. It adds richer messaging features to supported phone messaging apps, including branded business messages, product cards, buttons and replies.
Customers do not need to install a separate business app to receive RCS messages.
Their device, messaging app and network still need to support the features your campaign uses.
With RCS for Business, a brand can send rich cards and handle customer replies through a connected bot or support system.
RCS supports conversations as well as notifications.
Check your reachable RCS audience first
A large mobile database does not tell you how many customers can receive an RCS campaign.
Ask your provider to check your actual contact list for device capabilities and the business-messaging coverage available to your sender.
- RCS business messaging is available for the recipient’s network and market.
- The device and messaging app support your message’s features.
- Your approved sender can reach that recipient through the provider’s route.
To send RCS business campaigns, onboard an approved sender with a provider that covers your intended audience.
Airtel announced its RCS partnership with Google in March 2026.
A carrier announcement still does not tell you which contacts your particular business sender can reach.
RCS on iPhone depends on the supported software, carrier and business-messaging rollout.
Ask your provider to confirm your intended audience rather than assuming every iPhone that supports personal RCS chats can receive your campaign.
If RCS is unavailable, your provider can configure another route such as SMS. Delivery is still subject to that route’s availability and rules.
Google recommends checking delivery receipts before fallback to avoid sending duplicates.
What Is WhatsApp Business Messaging?
WhatsApp Business Messaging lets you send messages and manage customer conversations inside WhatsApp.
Customers need a supported device and an active WhatsApp account.
The WhatsApp Business App suits smaller teams handling chats manually.
The WhatsApp Business API connects messaging to software such as AiSensy’s WhatsApp marketing platform for campaigns, automation and team support.
With the API, the tools available to your business depend on the platform, account setup and applicable feature eligibility.
- Approved templates for business-initiated messages
- Chatbots and AI Agents through your chosen platform
- Product catalogs and supported commerce features
- Payments where available for your market and setup
- Ads that click to WhatsApp
- A shared team inbox through your provider
If you're new to it, start with our WhatsApp Business API guide.
RCS vs WhatsApp: Key Differences
Here is how RCS for Business and the WhatsApp Business API compare for a marketing campaign.
| What to compare | RCS for Business | WhatsApp Business API |
|---|---|---|
| Customer inbox | Supported phone messaging apps | The WhatsApp app |
| Reach | Depends on device capabilities, carrier, market and sender launch coverage | Depends on customers using WhatsApp, account eligibility and permission |
| Interactive marketing | Rich cards, carousels, suggested replies and actions | Media templates, buttons, catalogs and WhatsApp Flows where supported |
| Customer conversations | Replies can connect to bots and support systems through the provider | Replies can connect to bots, AI Agents and a shared team inbox through a platform such as AiSensy |
| Customer acquisition | Customers can start a chat through supported links or QR codes. They need a supported version of Google Messages with RCS enabled, and your business sender must be launched on their carrier. | Ads that click to WhatsApp can open a customer conversation |
| Setup | Register and verify a business sender; confirm provider launch coverage | Connect your business and number, complete applicable checks and prepare approved templates |
| Security | Encrypted in transit. RCS business messages are not end-to-end encrypted. | Encrypted delivery to the business endpoint. Meta-hosted business chats are not considered end-to-end encrypted; review provider access and storage controls. |
| Fallback | Another route such as SMS needs provider configuration and delivery checks | Another channel needs a separate integration; SMS fallback is not automatic |
| Cost | Provider-specific billing model, setup and any fallback fees | Message charges plus applicable platform subscription and add-ons |
Example: launching a clothing collection
Say you sell clothing online and want to introduce a new collection to previous buyers who have agreed to receive your promotions.
The following is an illustrative campaign, not a customer result.
Your message could say: “Our new collection is here. Browse the styles and ask us if you need help choosing a size.”
Use the same offer and landing page when comparing channels.
On RCS, show selected styles in rich cards with a website button.
Suggested replies can let a customer ask about sizing, with a connected bot or support system handling the answer.
Check that your provider supports this journey.
On WhatsApp, send an approved marketing template with a relevant product image and a catalog or website action where supported.
A customer can reply with a size question, and your configured chatbot or team can continue the conversation.
Plan the next step after the click.
Check stock and delivery details, decide who handles product questions, and stop promotional follow-ups when the customer buys or opts out.
Example: recovering an abandoned cart
A shopper adds a jacket to the cart but leaves before paying.
If you have permission to follow up, send a relevant reminder with a link back to the cart.
On RCS, your provider can build this around a product card and website action.
On WhatsApp, use an approved marketing template and let the shopper reply with questions about fit or delivery.
Connect cart and purchase data to the follow-up workflow so it stops after an order.
Your team can handle WhatsApp replies in AiSensy.
Compare recovered orders and cost per recovered order, using the same attribution period for each channel.
Example: filling salon appointment slots
Say your salon has appointments available before a festival.
Send a relevant offer to customers who have agreed to receive promotions.
An RCS card can take eligible customers to your booking page.
A WhatsApp template can invite a reply, with a configured Flow collecting service and timing preferences before your team confirms availability.
WhatsApp is useful when customers need advice before booking; RCS can suit a short route to an existing booking page.
Track confirmed appointments and attendance, so a reply or button click is not mistaken for a completed booking.
These are illustrative workflows, not reported customer results.
RCS and WhatsApp have separate inboxes.
Linking from an RCS message to WhatsApp can invite a new conversation, but it does not move the earlier RCS chat history into WhatsApp.
RCS vs WhatsApp Pricing in India
Your message bill is only part of the cost.
Compare the same audience, campaign and reporting period, then include the software and follow-up work needed to run it.
WhatsApp message charges through AiSensy
These are AiSensy’s listed message charges for Indian recipients, checked on 26 October 2026. Platform subscriptions, add-ons and taxes are extra.
| Message category | AiSensy’s listed India rate | Budget condition |
|---|---|---|
| Marketing | ₹1.09 per delivered message | Promotional campaigns, including the collection-launch example |
| Utility | ₹0.145 per delivered message | Includes utility templates inside the 24-hour service window under the current update |
| Authentication | ₹0.145 per delivered message | Applicable authentication messages; check destination and account pricing |
| Service | ₹0.145 after the free monthly allowance | First 1,000 service messages per business phone number per month are free |
From 1 October 2026, the first 1,000 service messages per business phone number are free each month, as confirmed in Meta’s updated WhatsApp Business FAQ.
After that allowance, AiSensy lists a service-message charge of ₹0.145 for Indian recipients.
Utility templates inside the 24-hour customer service window are also chargeable under the current update. Incoming customer messages and eligible messages within the 72-hour free entry point window remain free.
You can read the complete breakdown in our WhatsApp pricing update for October 2026.
Ask for an RCS quote that matches your campaign
RCS billing varies by provider, market and message model.
Get a quote for the campaign you’ll actually send, including any carousels, replies and SMS fallback.
Confirm the billing unit and how delivery, sender setup and fallback are charged.
Worked example: 10,000 delivered marketing messages
For 10,000 delivered marketing messages, AiSensy’s listed India rate gives a message charge of 10,000 × ₹1.09 = ₹10,900.
Use the table below to add the other costs and compare an RCS quote.
| Cost component | WhatsApp through AiSensy | RCS provider quote |
|---|---|---|
| Initial marketing send | 10,000 delivered messages × ₹1.09 = ₹10,900 | B × r: billable units (B) multiplied by the quoted rate per unit (r) |
| Software and setup | Applicable platform plan and enabled add-ons | Provider, sender, setup and platform fees |
| Follow-ups | Applicable message-category and destination charges | Additional billable units under the provider’s model |
| Fallback | Separate connected-route charges, if used | Configured SMS or other fallback-route charges |
| Taxes and paid acquisition | Add applicable taxes and advertising spend | Add applicable taxes and advertising spend |
| Total campaign budget | ₹10,900 + applicable costs above | B × r + applicable costs above |
Use B and r from the same RCS billing model: messages and conversations are different billing units. This is a budget framework, not an RCS price quote.
To compare business outcomes, divide the total campaign cost by the orders attributed under the same reporting rule.
If you are measuring qualified leads, use that outcome consistently for both channels.
Run a small test with comparable audiences and the same offer.
Measure cost per order or qualified lead alongside the message bill.
How to Choose Between RCS and WhatsApp Marketing
Start with your existing customer behaviour and the tools your campaign needs.
Before you choose a provider, check how it connects to your store or CRM and whether you can:
- Use customer and purchase data in your campaigns.
- Stop follow-ups when someone buys or opts out.
- Pass customer replies to the right team.
- Track each order once across the channels you use.
Consider RCS when
- You want to upgrade an existing SMS campaign with branded cards and carousels in the supported messaging inbox.
- Your provider’s capability check confirms a useful RCS audience for your sender.
- You already have an RCS provider or bot integration and want an SMS fallback route configured alongside it.
Consider WhatsApp when
- Your customers already enquire or buy through WhatsApp, and you want campaigns to connect with those conversations.
- You need WhatsApp catalogs or Flows for product browsing, forms or bookings.
- You acquire enquiries from Facebook or Instagram ads that click to WhatsApp.
- You want AiSensy broadcasts, automation and team replies in the same WhatsApp workflow.
Campaign Rules, Consent and Security in India
A phone number alone is not permission to send promotions.
Google’s RCS acceptable-use policy requires appropriate notice and consent.
Keep records of the permission you collect and honour opt-outs on the channels you use.
RCS promotional campaigns in India: Google’s India business rules limit initial messages to each customer over a rolling 28-day period: two for a low-reputation agent, four for medium and eight for high.
New agents start at low reputation.
Business-initiated conversations are allowed between 7 AM and 10 PM.
Replies to customer-initiated messages are exempt from these traffic limits; unique-audience and cross-agent limits also apply.
Abandoned-cart reminders count as promotional messages, so confirm that your RCS sender is approved for promotions and check its traffic limits before planning follow-ups. Multi-use agents, which combine promotional and transactional messages, are unavailable in India.
WhatsApp templates and replies: Under the WhatsApp Business Messaging Policy, you must use an approved template to initiate a conversation.
Each customer message opens or resets a 24-hour service window, during which you can reply without a template.
After that window closes, use an approved template to follow up.
Plan your response team and automation around that window, and honour the customer’s opt-out.
RCS for Business encrypts messages in transit between devices, Google and the messaging partner.
It does not offer end-to-end encryption.
WhatsApp protects message delivery with encryption, but business hosting changes who can process the content.
WhatsApp says business chats hosted by Meta are not considered end-to-end encrypted.
Review access and storage controls for the business and provider systems that handle your messages.
What Real Campaigns Show About RCS and WhatsApp
The following published campaigns show practical uses of each channel.
They were separate tests with different audiences, so their results cannot establish a head-to-head winner.
RCS: helping customers choose a holiday menu
In Sinch’s Picard case study, the French food retailer used an RCS chatbot to ask about dietary preferences and budget, then recommend a holiday menu.
Sinch reports a click-through rate three times higher than Rich SMS for that campaign.
Sinch compared that campaign with Rich SMS, rather than WhatsApp.
WhatsApp: helping shoppers ask before buying
In Meta’s Stylesplash case study, the Mumbai fashion brand used website to WhatsApp ads so shoppers could browse its website and ask questions about fit, style and price.
Stylesplash reported 3.5 times more customer conversations than its traditional website ads in a test.
Meta labels the results self-reported and says individual results vary.
For your clothing campaign, that suggests a practical question: do shoppers need sizing advice before they buy?
Build the response and team handover into the journey, then measure completed purchases as well as conversations.
Measure the full customer journey
Track how many eligible customers were sent a message, how many received it, and how many clicked, replied or bought.
Keep delivery rate separate from read rate and click-through rate.
Use the same definitions and attribution period across channels.
Record fallback deliveries separately so one customer is not counted twice.
If you compare different offers or very different audiences, the result will not isolate the channel’s effect.
Note those differences before deciding where to spend more.
Using RCS and WhatsApp Together
You can use both channels when each has a clear role.
For example, use an RCS campaign for eligible customers who prefer that route, and WhatsApp for customers who choose to enquire or shop there.
Keep one customer record across the routes you use, so a fallback send or follow-up does not repeat an offer the customer has already received.
- Choose the route before sending: check RCS capability and the customer’s preferred channel.
- Confirm delivery before fallback: avoid sending the same offer twice when switching to SMS or another route.
- Combine reporting by customer: label fallback sends separately and attribute each order once.

You can check the latest details on the AiSensy pricing page.
Choose the Channel Your Campaign Can Use Well
For your next campaign, check your reachable audience, the customer’s next action and the full cost of the journey.
Both RCS and WhatsApp can support interactive messaging; your setup and execution determine how useful that experience becomes.
If WhatsApp fits your audience, start with one relevant offer in AiSensy, prepare the answers customers may need, and measure the campaign through to the purchase.

FAQs
Does WhatsApp use RCS?
No. WhatsApp and RCS use separate messaging systems and inboxes. A message sent through one does not appear in the other.
Can both RCS and WhatsApp support chatbots?
Yes. Both can support automated conversations. Check how your provider connects replies to the bot, business data and human support.
Is RCS cheaper than WhatsApp marketing in India?
There is no universal answer. Compare your RCS provider’s current quote with the applicable WhatsApp message charges, platform costs, add-ons and fallback fees for the same campaign.
Does RCS business messaging work on iPhone?
Availability depends on the device software, carrier, market and business-messaging route. Confirm that your provider can reach your intended recipients; consumer RCS support alone does not establish campaign reach.
Does RCS automatically fall back to SMS?
A business provider needs to configure an SMS or other fallback route. It should check the original delivery status to prevent duplicate messages. The fallback route has its own requirements and cannot guarantee delivery.
Will RCS replace WhatsApp for businesses?
Businesses can use either or both. Choose according to customer preferences, reachable audience, supported workflows and total cost rather than assuming one channel will replace the other.
Can I use my WhatsApp marketing list for an RCS campaign?
Only if you have the permission required for that channel and purpose. Do not assume that holding a phone number or WhatsApp marketing consent covers a new RCS promotion.
How can I start a WhatsApp campaign with AiSensy?
Connect your business and number, complete the applicable onboarding checks, choose an eligible audience and prepare an approved template. Review current plan and message charges, test your customer response journey, then schedule the campaign when ready.
