Why SMS

Simple, immediate, and auditable.

Nothing reaches as far: SMS remains the channel with the widest reach in Brazil. At Sintalk, we measure it from end to end.

Direct route with carriers

No middlemen: premium, trackable delivery that doesn't get caught in spam filters.

OTP & transactional

Access codes and critical notifications with low latency and guaranteed delivery.

Shortlinks with attribution

Every click becomes an event on the contact’s profile, from the initial click to the conversion, with no black box.

Ideal for: OTP and verification · Transactional notifications · High-volume campaigns

Formats

Three formats, three goals.

Each campaign requires a specific type of SMS. In the dashboard, you choose the format, and Sintalk handles the delivery.

SMS (Short Message Service)

Up to 160 characters, including a link and a call to action. The quick conversion format: promotions, coupons, and invitations.

SMS Flash

Appears on the screen as soon as it is received, even if the device is locked. Urgent notification for bill and last call.

Transactional SMS

OTP, confirmations, and system notifications via API, with priority delivery and a complete audit trail.

Orchestration

The fallback that always comes up.

When RCS isn't supported or delivery fails, SMS automatically takes over. Same message, same rules, no contacts lost.
