Migration path
Twilio Programmable Messaging and Vonage Messages API are structurally similar. Swap SDK, map message parameters (Twilio From → Vonage from, Twilio StatusCallback → Vonage webhook event URL), update phone numbers (you can port numbers between carriers but it takes 1-3 weeks). Voice/TwiML is trickier — Vonage uses NCCO, requires rewriting IVR flows.

More Communication & Email comparisons
Resend vs SendGrid
Resend is the new developer-first transactional email API — React Email templates, great DX, simple pricing.
