Having accumulated over a decade of experience in the SMS marketing industry, we've noticed a troubling trend: 8-18% of text messages fail to reach their destination through carriers. Compounding the issue is the fact that carriers charge for messages, regardless of successful delivery. To combat this, we developed a solution that allows us to preview phone numbers before sending them to carriers. Despite encountering high prices from third-party vendors offering similar services, our research eventually uncovered a reliable and cost-effective solution. Implementing this into our SMS platform produced significant results. In just four months, one major client experienced a monthly savings of over $5300.00 in delivery fees.
