What is an SMS Aggregator?
An SMS aggregator is a company that connects businesses to mobile carrier networks. When you send an SMS through a platform like Twilio, Plivo, or others, aggregators handle the actual delivery to carriers.
Major SMS Aggregators
- Syniverse — One of the largest global aggregators
- Sinch — Major player after acquiring several providers
- Bandwidth — Also operates as a carrier
- Twilio — Uses multiple upstream aggregators
- Plivo, Vonage, etc. — Various other providers
Why Detect Aggregators?
Routing Optimization
If you know which aggregator handles a recipient's messages, you can:
- Route through direct connections when available
- Avoid aggregators with known issues
- Reduce hops for faster delivery
Troubleshooting
When delivery fails, knowing the aggregator helps identify where issues occur. You can work with the specific provider to resolve problems.
