Customer Reviews
Consistent performance, good value
This was my third time using Signal House for our bulk SMS needs, and as always, the service was reliable. I've found their SMS Gateway to be consistently fast, and the API documentation is always clear, which makes integration smooth. Compared to my previous order a few months back, the performance for the delivery reports was just as solid. It's why I keep coming back for our business messaging.
Messaging Platform is super great
I can't say enough good things about Signal House! I used their Messaging Platform and it was so easy to set up with our marketing automation system. The delivery reports were instant and accurate, which is a huge plus for our campaigns. I had some free trial credits to get started, and they went a long way. I'm definitely planning on moving all our SMS workflows over to them. I've already told my team about it and they're excited to try it for their projects. Will be shopping here again for sure!
Quick setup, reliable service
Signed up for the SMS API. Setup was fast, and the API documentation was straightforward. My test messages went through without issues. The delivery reports were accurate. No complaints with the service.
Good value, free credits helped
As a first-time buyer, I was looking for the most cost-effective way to implement two-way messaging for our startup. Signal House offered some free API testing credits, which was a big draw. It allowed me to fully test the Inbound Message Handling and SMS Autoresponders without commitment. The per-message rates seemed reasonable after that, especially considering the quality of the service. I felt like I got good value for my money and the experience was worth it.
