RCS for Business. Built for Microsoft Teams
RCS for Business is a secure, interactive messaging channel designed for modern customer engagement.YakChat embeds RCS directly into Microsoft Teams, enabling branded, outbound-first conversations with rich content — all within the workspace your organisation already uses.With RCS in Teams, users can send longer messages, share high-quality images and files and include interactive buttons to guide responses and keep conversations moving.
The evolution of SMS
Trusted, Branded Business Messaging
RCS goes beyond SMS with verified brand identity, security and message insight – directly inside Microsoft Teams.
Branded Messages
Messages display your Google verified business name and logo instead of a number so customers recognize and trust who the message is from.
Encrypted Delivery
Messages are encrypted in transit to help protect communications. This adds a layer of data security not available with traditional SMS.
Read Receipts
See when messages are opened to better understand customer engagement. Use this insight to time follow-ups and next steps more effectively.

Team Inboxes

Compliance built-in
YakChat + RCS: Compliance by Design
Using RCS on personal phones puts your business at risk of shadow IT. Messages are scattered across individual devices with no central oversight, records or control.If a message is deleted, it’s gone. Lose an employee, and you lose the entire conversation. GDPR and FCA obligations around data access, retention, consent and auditability can be breached in an instant.YakChat provides a controlled, auditable way to use RCS in Microsoft Teams. Messages are centrally managed, archived and retained in line with organisational policies - ensuring data protection and compliance.Built-in opt-out handling ensures customer preferences are respected, reinforcing compliant messaging.
One platform. Every channel.
Add More Messaging Channels to Microsoft Teams
RCS is a core messaging channel, but effective engagement spans multiple channels.YakChat unifies SMS, WhatsApp and RCS in a single workspace — so teams can shift conversations between channels and devices without compromising context, compliance or control.
