RCS and email are complementary: RCS wins on immediacy and engagement, email wins on long-form content, attachments, and archiving. RCS messages land in the phone’s inbox and are read within minutes, with read rates and click-through far above email; email is better for newsletters, detailed content, documents, and records customers expect to keep and search. Most businesses use RCS for time-sensitive, action-oriented messages and email for depth and archives.

Why the engagement gap is structural, not cosmetic
Email competes with everything. A promotional send lands in a tab beside hundreds of other messages, is filtered by rules nobody controls, and is read hours later if at all. RCS lands in the messaging inbox, which people open dozens of times a day and where almost nothing arrives that they did not ask for. There is no promotions tab and no spam folder to fall into, and the sender is verified by Google and the carriers rather than asserted by a display name. That is why RCS click-through commonly runs 15-30% against a few percent for email: the difference is the surface, not the copywriting.
Where email still wins, and how to split the work
Email remains the right home for anything the customer needs to keep. Invoices, statements, itineraries, policy documents, receipts, long-form newsletters, and anything with an attachment belong in an inbox that is searchable years later and reachable from a desktop. RCS is not built to be an archive, and it is a poor fit for content that needs layout, length, or a PDF. The split most brands settle on is simple: RCS for the moment something happens, the order shipped, the appointment moved, the offer expires tonight, with a button that resolves it in one tap, and email for the record of what happened, sent alongside. Used that way the two raise each other rather than competing for the same send.
Email’s strengths are reach to any address, rich layout, attachments, and permanence. RCS’s strengths are speed, native-inbox attention, verified identity, and one-tap actions. They work best together rather than as substitutes.
- RCS click-through commonly runs 15-30%, well above typical email click rates of a few percent (industry benchmarks).
- RCS has no spam folder or promotions tab, and the sender is verified by Google and the carriers before a single message goes out.
- Email is the better channel for attachments, long-form content, and records customers expect to search later.
- SimplyRCS prices an RCS text at $0.0039 and a rich message at $0.0150, so cost per action is the fair way to compare it with an email program.
RCS vs Email, common questions.
Can RCS replace email marketing?
For time-sensitive, high-intent messages like order updates, alerts, and offers, RCS reaches customers faster and is opened far more often than email. Email still suits long newsletters and attachments, so most brands use both.
Why do RCS messages get opened more than email?
RCS lands in the phone’s messaging inbox, which people check constantly, from a verified business sender. There is no spam folder and no promotions tab to bury it.
Is RCS harder to set up than email?
Setup involves carrier verification of your brand, which SimplyRCS handles for you. After that, sending is as simple as email, with richer cards and buttons.
What click-through rate should I expect from RCS versus email?
Industry benchmarks put RCS click-through commonly in the 15-30% range, against a few percent for a typical marketing email. The gap comes from the surface, a native inbox with a verified sender and one-tap actions, rather than from better copy.
What should stay in email?
Anything the customer needs to keep or search later: invoices, statements, itineraries, policy documents, long-form newsletters, and anything with an attachment. RCS is not built to be an archive.
How do RCS and email costs compare?
Email is cheaper per send; RCS is $0.0039 a text or $0.0150 with media on SimplyRCS. The fair comparison is cost per action, where a channel read within minutes with a button in the message usually closes the gap and then some.
