Unrivaled Consistency and Reliability 🤝

We’ve optimized for that, building highly-reliable messaging APIs that consistently deliver.

Our engineers have taken special care to rigorously test our APIs, ensuring consistent message delivery without bottlenecks.
High Throughput and Scalability 📈

Speed is foundational to Signal House’s ethos. We pride ourselves on ensuring your messages reach their destination faster than our competitors.

Part of that is ensuring our APIs and databases are highly-scalable and leverage automatic scaling. However, we take this a step further.

Over time, we’re able to identify peak traffic times and procure additional bandwidth ahead of time, ensuring speedy delivery regardless of the time of day.

Have a special message that needs to go out to millions of people? 😬

No sweat, we can plan for that—expanding our utilized hardware and reserving space for your company with plenty of time to spare 😎
Developers Deserve Exceptional Experiences too ❤️

As a developer, a key function of your role is creating exceptional experiences for end users.

However, you’re also often neglected by the tools you utilize and we don’t think that’s fair.

So, our engineers have deliberately worked to provide intuitive APIs, simple-to-use SDKs, and sandboxes to do all the testing you need to feel confident your solution will seamlessly fit your needs immediately upon deployment.

Signal House does API differently, offering detailed documentation, proactive scalability, and intuitive implementation that your team will actually enjoy using 😍

“Utilizing Signal House for our messaging was a turning point for our company. Prior to moving to SH, we experienced poor support, messages getting filtered (up to 60%!), and paying a premium. We are saving over $40,000 per month with Signal House.”

Frequently Asked Questions

What is Tier 2 Aggregation?

Signal House is a Tier 2 Aggregator which means, at most, your messages will go through one additional layer before reaching the carriers and your customer’s handsets. This is in contrast to many CPaaS providers who go through 3-4 layers before doing the same.

This enables us to deliver messages in <1 second, have quick support turn-around times, and provide you with unrivaled transparency and visibility into the metrics that matter most.

What is a CPaaS?

CPaaS stands for Communications Platform as a Service. It’s a cloud-based platform that provides businesses with Application Programming Interfaces (APIs) for integrating real-time communication features like SMS, voice calls, video chat, and more, into their applications.

Can I use Signal House instead of Twilio?

Yes! Signal House offers the same services as Twilio; however, we provide up to 90% cheaper pricing, unparalleled support for all business types, superior integrations and documentation, and higher message throughput. If you are currently using Twilio looking for better delivery and pricing, Signal House is your partner!

Will we have downtime when we switch?

No! We leverage our connections with the Direct Connect Aggregators (DCAs) and other upstream partners to ensure seamless migration of any existing messaging campaigns.

Why is your messaging so much cheaper than Twilio?

We are very transparent with our pricing and don’t price gouge. With our strong network partnerships we are able to leverage substantial discounted pricing and pass those savings to our clients.

Can I port numbers to Signal House?

Absolutely! Our proprietary LOA port infrastructure supports single and bulk phone porting for 10DLC and Toll Free.

What are registration (A2P) fees for 10DLC?

We do not make a margin on 10DLC, A2P registration fees— they are passed-through to the upstream providers (TCR, DCAs, etc.). They are as follows:

Brand: $4.50 (each time the brand is attempted to be verified; usually this is one-time)

Campaign: $15 (one time)

Low Volume Campaign: $1.50/month

Standard Campaign: $10/month
