Signal House is a developer-focused SMS and messaging API for businesses that want to build texting, notifications, or two-way messaging directly into their own product.
Key features
- 10DLC (10-digit long code) SMS sending built for US application-to-person messaging
- Toll-free SMS and MMS support alongside standard long code messaging
- Direct API access designed for developers to integrate into existing apps
- Tier 2 Aggregator carrier relationships, which can affect deliverability and fees
Pricing
10DLC SMS starts from around $0.0065 per segment, dropping to around $0.0030 per segment at volumes above 10 million messages per month, plus about $1/month per phone number. Toll-free SMS starts from around $0.0079 per segment, and MMS starts from around $0.02 per segment. Carrier pass-through fees of roughly $0.0035 to $0.0045 per message are typically billed separately from the advertised per-segment rate. Confirm current pricing on Signal House’s site, since carrier fees change independently of platform pricing.
Pros and cons
| Pros | Cons |
|---|---|
| Per-segment pricing drops significantly at high volume | Carrier pass-through fees are billed separately from base rates |
| Supports 10DLC, toll-free, and MMS from one API | Requires development resources to integrate, not a no-code tool |
| Built specifically for developers embedding messaging into products | Not suited to teams wanting a simple dashboard-only messaging tool |
Who it’s for
Product and engineering teams building notifications, order updates, or two-way SMS features directly into their own app or platform will get the most from Signal House’s API-first approach.
Who should skip it
Non-technical teams that just want to send marketing texts from a simple dashboard, without writing code, would be better served by a no-code SMS marketing tool.
How to get started
Review the API documentation and pricing for your expected message volume, then register a 10DLC or toll-free number before integrating the API into your application.
FAQ
Are carrier fees included in Signal House’s advertised pricing?
No, carrier pass-through fees are typically billed separately from the per-segment rate, so your total cost per message will usually be higher than the base rate alone.
Do I need to write code to use Signal House?
Yes, Signal House is built as a developer API rather than a no-code dashboard tool, so integrating it requires development work.
