# SigSpan Reviews
**Vendor:** SigSpan  
**Category:** [IT Alerting Software](https://www.g2.com/categories/it-alerting)
## About SigSpan
SigSpan is a hosted email-to-SMS gateway built for IT and operations teams that rely on email-based alerting for critical infrastructure monitoring. It accepts inbound alert emails via a dedicated relay address and delivers them as SMS messages to on-call staff — no app installs, no monitoring tool reconfiguration required. SigSpan is a drop-in replacement for retiring carrier email-to-SMS gateways including Verizon, AT&T, and T-Mobile, which are shutting down their free relay services. Pricing is per-SMS with volume tiers starting at $0.10/message, with no monthly minimums. Trusted by a U.S. financial institution, a California county hospital, and a national drug testing laboratory for production alert delivery.
