REAL-WORLD RESULTS

Trusted in highly demanding industries

Effortless marketing compliance

Retail brands can automatically stop sending marketing messages when customers opt out, reducing manual work and lowering the risk of accidental sends.

Preserve critical communications

Logistics teams let customers unsubscribe from promotions while still receiving essential delivery updates—maintaining compliance without disrupting the experience.

Complex financial alerts

When a user texts “STOP,” you receive a webhook so your system can apply the right business rules before suppressing future messages—ideal for financial services and regulated workflows.

Regulatory compliance

Financial institutions can retrieve complete, time-stamped consent histories through the API, making audits faster and simplifying compliance reporting.
