Key Insight
RCS messages achieve 85-95% open rates vs push notifications 5-15% in India. Full comparison of reach, opt-in requirements, cost, and when each channel wins for Indian businesses.
Both RCS messaging and push notifications reach users on mobile phones. But they work through completely different mechanisms and produce very different results.
How They Reach Users Differently
RCS messaging:- Delivered via your carrier (Jio, Airtel, Vi) to the native Android Messages app
- Requires only a mobile number — nothing else
- No app download or notification permission required
- Works on any Android phone on supported Indian carriers
- Delivered through your app or website browser
- Requires app installed AND notification permission granted
- 40-60% of Indian users deny notification permissions on prompt
- Requires internet at moment of delivery
Opt-In Requirements: RCS Wins on Reach
| Factor | Push Notifications | RCS |
|---|---|---|
| What user needs | App + permission granted | Mobile number only |
| % of database reachable | 20-40% (app users who allowed) | 80-95% of Android users |
| Permission denial rate | 40-60% deny on prompt | No separate permission needed |
- Push notifications reach: 2,000-4,000 (only app users who allowed)
- RCS reaches: 8,000-9,500 (all Android users on Jio/Airtel/Vi)
Open Rate and Engagement
| Metric | Push Notifications | RCS |
|---|---|---|
| Average open rate | 5-15% | 85-95% |
| Click-through rate | 3-8% | 8-15% |
| Rich media | Limited (image, title, body) | Full (carousel, video, CTAs) |
Cost Comparison
| Volume | Push Notifications | RCS |
|---|---|---|
| Platform cost | Rs 3,000-30,000/month (Firebase, OneSignal, CleverTap) | No platform fee |
| Per notification | Rs 0-0.02 (volume included in platform) | Rs 0.18 per delivered RCS |
| 1 lakh sends | Rs 0-2,000 + platform | Rs 18,000 |
If push reaches 30% of list at 5% CTR, and RCS reaches 90% at 10% CTR:
- Push: 1,00,000 x 30% x 5% = 1,500 clicks
- RCS: 1,00,000 x 90% x 10% = 9,000 clicks
RCS generates 6x more clicks. At 9x the per-message cost, cost-per-click is approximately 1.5x — still significantly more clicks for roughly comparable total spend.

Setup Requirements
| Factor | Push Notifications | RCS |
|---|---|---|
| Technical setup | App development or website SDK | Managed by RCS provider |
| Development cost | Rs 50,000-5,00,000 for app | Zero (no app needed) |
| Ongoing maintenance | App updates, SDK maintenance | Zero |
| Time to first campaign | Weeks to months | 10-14 days |
For businesses without an app — the majority of Indian SMBs — push notifications are simply not viable. RCS works with just mobile numbers.
When to Use Each
Use Push Notifications when:- You have an established app with active users
- Real-time in-app alerts are needed (Swiggy delivery, banking transactions)
- Your users are highly app-engaged (fintech, food delivery, gaming)
- You do not have an app (most Indian SMBs)
- You want to reach your entire phone database, not just app users
- High open rates for time-sensitive communication are needed
- Your audience is primarily Android users on Indian carriers
Industry-Wise Recommendation
| Industry | Recommended Primary | Why |
|---|---|---|
| Coaching institutes | RCS | No app, high student mobile numbers |
| E-commerce with app | Push + RCS | Push for in-app, RCS for lapsed users |
| Hospitals | RCS | Patients do not install hospital apps |
| Real estate | RCS | Prospects do not install developer apps |
| Banking with app | Both | Push for in-app, RCS for non-app users |
| Retail without app | RCS | No app = push not possible |
Case Study: RCS Beats Push for Re-Engagement
An e-commerce brand with 2 lakh past customers ran a Diwali sale campaign:
- Push notification (sent to 60,000 app users who opted in): 4,200 opens, 840 clicks, 126 orders
- RCS (sent to 2,00,000 total database): 1,72,000 opens, 17,200 clicks, 2,580 orders
RCS generated 20x more orders from the same Diwali campaign. The difference: RCS reached the full database, not just app users with permissions.
Frequently Asked Questions
Can I use both RCS and push notifications together?
Yes — many brands use push for existing app users and RCS for the wider mobile database. Maximum reach is achieved by combining both.
Is RCS better than push for re-engagement?
For lapsed users who stopped using your app, RCS reaches them regardless of app status. Push cannot reach users who uninstalled your app. RCS is significantly better for re-engagement campaigns.
Which feels more personal?
RCS arrives in the SMS inbox — same as personal messages. Push notifications are increasingly associated with marketing and dismissed reflexively.
Does RCS work on iPhone?
Yes — since iOS 18 (2024), Apple added RCS support. Indian iPhone users on Jio, Airtel, and Vi can receive RCS messages.
