FAQ
WhatsApp marketing software questions
Is SemiOffice an unrestricted WhatsApp bulk sender?
No. It is designed for business contacts who have opted in. Live sending requires an official WhatsApp Business Platform connection and platform safety approval.
Why is there a free 50,000-message software allowance?
The Free plan lowers the barrier to trying the product. Paid plans add much larger software-processing allowances while WhatsApp/Meta/provider messaging charges remain separate.
Can an agency use it for multiple clients?
The application already has separate workspaces and platform-level controls. The Agency plan starts at $79/month; multi-workspace provisioning is reviewed during activation so client separation and volume can be configured safely.
Can I download the software as an app?
Yes. Install the free SemiOffice web app on Android, iPhone, Windows or Mac using your browser. There is no separate APK or desktop installer.
Can I use the free tools without creating an account?
Yes. The public generators work in the browser and are intended to be useful before signup.
