I really like the unified platform GreenAds Global offers called Telinfy, which includes WhatsApp, SMS, and RCS. The fallback messaging feature is particularly beneficial because if a message isn't delivered on WhatsApp, it automatically gets sent via SMS. This ensures that important messages, like OTPs, are not missed even if the customer is offline. Also, the automation of customer conversations has been a huge help in handling many customers. The quick response from the sales team was great too; within 48 hours of confirming I needed the service, I received my credentials for the Telinfy account. Review collected by and hosted on G2.com.
