Frequently Asked Questions
How does Zavu compare to Twilio?
Zavu offers the same SMS capabilities with a flat per-message rate that already includes US carrier fees: $0.004 per US message versus Twilio's $0.0083 plus $0.0035 to $0.0045 in carrier fees. Registry fees like 10DLC are identical pass-through on both. On typical US traffic that is roughly a third of the effective Twilio cost.
How long does it take to integrate?
