Why people consider alternatives to Twilio
Twilio is a cloud communications platform providing APIs for SMS, voice, video, WhatsApp, email, and authentication services. It enables developers to programmatically send messages and make calls.
Here are the real cost and limitation gotchas that push teams to look elsewhere:
- Carrier surcharges: US carriers charge $0.003-$0.005 per SMS on top of Twilio's rate. A $0.0083 message actually costs $0.011-$0.013 delivered.
- Phone number fees: $1.15/month per local number, $2.15/month per toll-free. A pool of 50 numbers for throughput costs $57-107/month before sending a single message.
- A2P 10DLC registration: Required for US business SMS. Brand registration $4 (one-time), campaign registration $15/quarter. Non-compliance means messages get filtered.
- Short code fees: $1,000/month per US short code. Required for high-volume campaigns. Plus carrier fees and approval process taking 8-12 weeks.
