Signal House is a business SMS and MMS platform with per-message pricing and an API for developers. It is aimed mainly at the US market, so it helps startups in the region that serve US customers, and is not the right choice for messaging within the region.
Key features
- 10DLC numbers: registered US local numbers for business messaging.
- Toll-free numbers: for higher-volume messaging.
- MMS: send images and media.
- API: build messaging into apps and CRMs.
- Registration support: to meet US carrier requirements.
