Signal House FAQ

Frequently asked about Signal House

Does Signal House support self-hosting or is it fully SaaS-only?

Signal House is a modern SaaS platform and does not currently offer a self-hosted deployment option. All messaging infrastructure and API endpoints are hosted and managed by Signal House, so teams must rely on their cloud service rather than on-premises installation.

Community insight informed by Reddit discussions

Can Signal House operate offline or queue messages locally if connectivity is lost?

Signal House requires an active internet connection to send and receive SMS messages through its API. It does not provide offline functionality or local message queuing; any message queuing or retry logic must be implemented client-side by the integrating application.

Community insight informed by StackOverflow discussions

What are the data ownership and privacy guarantees with Signal House?

All message data processed via Signal House is stored and managed within their cloud infrastructure. While Signal House adheres to industry-standard security and privacy practices, ultimate data ownership remains with the customer, but data residency options and export capabilities depend on the plan tier and region.

Community insight informed by Hacker News discussions

Are there any notable API limitations or rate limits developers should be aware of?

Signal House enforces API rate limits that vary by subscription tier, with higher tiers allowing greater throughput. Additionally, some advanced messaging features and webhook configurations are only available in premium plans.
