Key Insight
RCS messaging delivers 8-15% CTR vs email 2-5% in India. Complete comparison of open rates, cost, deliverability, and when each channel wins for Indian businesses.
Most Indian businesses use email marketing and wonder whether RCS messaging is worth adding. This guide gives you a direct comparison on every metric that matters.
Bottom line upfront: RCS wins on open rates, CTR, and immediacy. Email wins on content depth, cost-per-contact, and nurturing. They serve different jobs.Open Rate: RCS Wins Significantly
| Metric | Email Marketing | RCS Messaging |
|---|---|---|
| Average open rate | 18-25% (India) | 85-95% |
| Opens within 1 hour | ~20% of total opens | ~90% of total opens |
| Reason | Inbox competition, spam filters | Native message app — same as personal SMS |
Email open rates in India are suppressed by Gmail's Promotions tab, which filters most marketing emails automatically. Many users never open the Promotions tab for days.
Click-Through Rate: RCS Wins
| Metric | RCS | |
|---|---|---|
| Average CTR | 2-5% | 8-15% |
| Why | Link buried in body text | Tap-to-action buttons inside the message |
RCS messages contain visible, tappable CTA buttons — "Book Now," "Get Offer," "Track Order." No scrolling required. No link copying. One tap.
Email CTR suffers because most email readers scan — they do not read. Links embedded in text are easy to miss. Images are often blocked by default in corporate email clients.
Cost Comparison: Email Wins at Scale
| Volume | Email (India) | RCS |
|---|---|---|
| 1,00,000 contacts | Rs 6,000-15,000/month | Rs 17,000 per send |
| 4 sends per month | Rs 6,000-15,000 total | Rs 68,000 total |
| Platform fee | Rs 2,000-10,000/month | Included in per-message rate |
Deliverability: RCS Wins in India
Email deliverability in India faces significant challenges:
- Gmail Promotions tab filters most B2C marketing email
- Corporate email clients have aggressive spam filters
- Email bounce rates of 5-15% are common with older lists
- Many Indian users use free Gmail — high competition for inbox space
RCS deliverability:
- Delivered to Android SMS inbox — no spam folder for RCS
- Fallback to SMS if RCS unavailable — message still reaches the device
- Delivery confirmation and read receipts available
Practical implication: An email with 25% open rate means 75% of your list never saw your message. An RCS message with 90% open rate means 90% of your list saw it within an hour.
Content Depth: Email Wins
This is where email has a clear advantage:
- Email can carry 2,000 words, multiple images, detailed HTML design
- RCS messages are limited to short, action-oriented content
- Long-form newsletters, product updates, detailed proposals — use Email
- Short action-oriented messages — use RCS
When to Use Each Channel
Use RCS for:- Flash sales and time-limited offers (high urgency)
- Appointment reminders (healthcare, services)
- Order and delivery updates

The Best Strategy: RCS + Email Together
The highest-performing Indian businesses use both at different stages:
Awareness: Email newsletter builds relationship over months at low cost. Action: RCS fires at the moment of decision — when a sale is live, seat is limited, or lead is hot. Example — Coaching Institute:- Email: Monthly educational content about exam preparation
- RCS: "Batch starts Monday — 3 seats left. Confirm now" sent 48 hours before deadline
ROI Comparison — 1 Lakh Database, Same Month
Assume 1 lakh contacts, Rs 5,000 average order value, 20% of clicks convert.
| Channel | Cost | Open Rate | CTR | Conversions | Revenue | ROI |
|---|---|---|---|---|---|---|
| Email (4 sends) | Rs 15,000 | 22% | 3% | 1,320 | Rs 66,00,000 | 440x |
| RCS (1 send) | Rs 17,000 | 90% | 10% | 9,000 | Rs 4,50,00,000 | 2,647x |
| RCS + Email | Rs 32,000 | Both | Both | 10,000+ | Rs 5,00,00,000+ | 1,562x |
The combined approach wins — email provides the frequency and nurturing, RCS provides the high-conversion moments.

Frequently Asked Questions
Is RCS cheaper than email marketing for Indian businesses?
For infrequent high-impact campaigns, email is cheaper per contact. For single high-urgency sends where engagement rate matters, RCS delivers significantly better ROI despite higher per-message cost.
Can RCS and email be sent to the same database?
Yes — but they use different identifiers. Email campaigns need email addresses. RCS campaigns use mobile numbers. Most Indian businesses have both.
Which has better ROI for coaching institutes?
Based on campaigns managed by Scalify Labs: RCS generates 3-5x more admissions per 1,000 sends compared to email for time-sensitive admission campaigns. Email is better for monthly content that builds trust between admission cycles.
