Frequently Asked Questions
5 questions
Twilio is superior for transactional SMS. It offers lower per-message pricing ($0.0075 vs $0.01), covers 150+ countries, provides real-time delivery tracking, and integrates seamlessly into application workflows. Mailchimp's SMS is better suited for marketing campaigns, not high-volume transactional use.
