SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Developers often default to SMS without considering whether RCS or WhatsApp would better fit their use case, leading to poor reach, missing rich content, or weak brand presence. This Skill qualifies a messaging use case across content type, geography, use case, cost, and branding before recommending a channel.

Core Features & Use Cases

  • Channel Qualification: Evaluates content type (plain text, media, rich interactive), recipient geography (US, LATAM, APAC, EU), and use case (marketing, notifications, OTP, support) to pick the right channel.
  • Vocabulary Translation: Maps loose developer phrasing like "send an SMS" or "branded message" to the correct channel, including redirects to Twilio Verify for OTP flows.
  • Proactive Pushback: Flags when a stated SMS request would be better served by RCS or WhatsApp, with fallback configuration guidance.
  • Use Case: A developer says "send SMS to customers in Brazil with product images" — the Skill recommends WhatsApp as primary with SMS fallback, then hands off to the send-message and messaging-services skills.

Quick Start

Ask the advisor which Twilio messaging channel to use for sending branded order updates with images to customers in Mexico.

Frequently Asked Questions about twilio-messaging-channel-advisor

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I choose between SMS, RCS, and WhatsApp for my app?▼

Choose based on content type, geography, and branding needs. SMS fits plain text and time-sensitive alerts, RCS fits branded rich content in the US on iOS 18+ and Android, and WhatsApp fits international reach in LATAM and APAC or conversational support.

What Twilio channel should I use for marketing messages?▼

For US marketing with rich content, use RCS with SMS fallback. For international promotional campaigns, use WhatsApp template messages, which require approval and are charged per conversation within a 24-hour window.

Does RCS work on both iPhone and Android?▼

Yes, RCS is supported on iOS 18+ and Android, making it the option for cross-device branded messaging with one experience. Configure SMS fallback through Twilio Messaging Services for older devices without RCS support.

Should I use SMS or Twilio Verify for OTP codes?▼

Use Twilio Verify instead of raw messaging for OTP and verification codes. Verify handles rate limits, retries, and fraud protection, and works across SMS, WhatsApp, RCS, push, and TOTP channels.

When is WhatsApp better than SMS for messaging?▼

WhatsApp is better when recipients are in WhatsApp-dominant markets like Brazil, Mexico, or India, when you need rich interactive templates, or for conversational support that fits its 24-hour session model. SMS remains the fallback channel.
