Why should I use a single toll-free number instead of spreading messages across multiple numbers?

Spreading similar messages across multiple numbers as a way to avoid per number rate limits and volume limitations is called “snowshoeing” and is a common technique used by spammers. Adopting this technique often results in your messages being blocked based on your message content, including your URLs. Using a single toll-free number provides a better user experience for businesses and their customers and reduces the likelihood that TCPA-compliant (Telephone Consumer Protection Act) messages will be blocked for violating CTIA guidelines than using pools of rotating numbers.
