Quick answer. 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.
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.
Key facts
- RCS click-through commonly runs 15–30%, well above typical email click rates of a few percent (industry benchmarks).
