RCS Messaging in Sparkforge: Setup, Reach, and Best Practices

By Sparkforge Support Team ·Last reviewed May 3, 2026

RCS lets you send branded messages with images, buttons, and read receipts to compatible recipients. Sparkforge falls back to SMS automatically when a contact can't receive RCS, so design every message to work both ways.

Rich Communication Services (RCS) is a modern messaging standard that supports branded sender names, rich media, tappable buttons, and read receipts. Sparkforge falls back to SMS automatically when a recipient can't receive RCS.

What you can send with RCS

Branded messages displaying your business name in supported inboxes
Images and rich layouts
Tappable buttons (Call, Open URL, Suggested replies)
Interactive cards and carousels (where enabled)

RCS vs SMS vs MMS

Feature	RCS	SMS	MMS
Reach	Compatible devices only	Nearly universal	Nearly universal
Branding	Business name visible	Phone number	Phone number
Media	Native rich media and cards	Text only	Media (less consistent)
Buttons	Yes	No	No
Read receipts	Often available	No	No
Fallback	Falls back to SMS	N/A	N/A

Best practice: always design messages so they still work as plain SMS.

Who can receive RCS

RCS reaches recipients who have an RCS-supported device, an RCS-capable messaging app, RCS enabled in their settings, and a supported carrier or network. Some recipients on your list will get RCS; others will receive the SMS fallback.

Android

RCS is widely supported on Android devices using Google Messages or carrier-supported apps. Recipients can disable RCS in their settings.

iPhone

iPhone RCS support depends on OS version, app ecosystem, and carrier enablement. Many iPhone recipients will receive SMS fallback instead.

Brand and number requirements

Your business sender identity must be registered and approved before you can send RCS at scale.
Use phone numbers provisioned for RCS-eligible traffic.
Keep content compliant with carrier and Google policies (no prohibited categories, no deceptive content).

Best practices

Lead with the message; treat rich elements as accents, not crutches.
Keep buttons short and action-oriented (Book, Reply YES, View order).
Use images that read clearly at thumbnail size.
Always include a working SMS fallback version.
Test with both Android and iPhone recipients before launching a campaign.

Frequently Asked Questions

What happens if a recipient can't receive RCS?

Sparkforge automatically falls back to SMS when a recipient's device, app, settings, or carrier doesn't support RCS, so the message still gets through.

Do iPhones receive RCS messages?

iPhone RCS support depends on iOS version, messaging app, and carrier. Many iPhone recipients receive SMS fallback instead of RCS.

Can I send RCS campaigns to a contact list?

Yes. Use Bulk Actions in Sparkforge to send RCS campaigns. Recipients without RCS support get the SMS fallback.

Does RCS work on every Android phone?

Most modern Android devices using Google Messages or a carrier RCS app support RCS, but recipients can disable it in their settings.

Can I track if an RCS message was read?

Read receipts are often available with RCS, depending on the recipient's app and settings. SMS does not provide read receipts.
